     * Note that this function expects normal calendar dates, meaning that months are 1-based (i.e. 1 = January).
     * The {@link #defaults} hash will be used for any date value (i.e. year, month, day, hour, minute, second or millisecond)
     * which cannot be found in the passed string. If a corresponding default date value has not been specified in the {@link #defaults} hash,
     * the current date's year, month, day or DST-adjusted zero-hour time value will be used instead.
     * Keep in mind that the input date string must precisely match the specified format string
     * in order for the parse operation to be successful (failed parse operations return a null value).

 * @class Ext.Loader
 *

Ext.Loader is the heart of the new dynamic dependency loading capability in Ext JS 4+. It is most commonly used
via the {@link Ext#require} shorthand. Ext.Loader supports both asynchronous and synchronous loading
approaches, and leverage their advantages for the best development flow. We'll discuss about the pros and cons of each approach:

# Asynchronous Loading #

- Advantages:
        + Cross-domain
        + No web server needed: you can run the application via the file system protocol (i.e: `file://path/to/your/index
 .html`)
        + Best possible debugging experience: error messages come with the exact file name and line number

- Disadvantages:
        + Dependencies need to be specified before-hand

### Method 1: Explicitly include what you need: ###

    // Syntax
    Ext.require({String/Array} expressions);

    // Example: Single alias
    Ext.require('widget.window');

    // Example: Single class name
    Ext.require('Ext.window.Window');

    // Example: Multiple aliases / class names mix
    Ext.require(['widget.window', 'layout.border', 'Ext.data.Connection']);

    // Wildcards
    Ext.require(['widget.*', 'layout.*', 'Ext.data.*']);

### Method 2: Explicitly exclude what you don't need: ###

    // Syntax: Note that it must be in this chaining format.
    Ext.exclude({String/Array} expressions)
       .require({String/Array} expressions);

    // Include everything except Ext.data.*
    Ext.exclude('Ext.data.*').require('*'); 

    // Include all widgets except widget.checkbox*,
    // which will match widget.checkbox, widget.checkboxfield, widget.checkboxgroup, etc.
    Ext.exclude('widget.checkbox*').require('widget.*');

# Synchronous Loading on Demand #

- *Advantages:*
        + There's no need to specify dependencies before-hand, which is always the convenience of including ext-all.js
 before

- *Disadvantages:*
        + Not as good debugging experience since file name won't be shown (except in Firebug at the moment)
        + Must be from the same domain due to XHR restriction
        + Need a web server, same reason as above

There's one simple rule to follow: Instantiate everything with Ext.create instead of the `new` keyword

    Ext.create('widget.window', { ... }); // Instead of new Ext.window.Window({...});

    Ext.create('Ext.window.Window', {}); // Same as above, using full class name instead of alias

    Ext.widget('window', {}); // Same as above, all you need is the traditional `xtype`

Behind the scene, {@link Ext.ClassManager} will automatically check whether the given class name / alias has already
 existed on the page. If it's not, Ext.Loader will immediately switch itself to synchronous mode and automatic load the given
 class and all its dependencies.

# Hybrid Loading - The Best of Both Worlds #

It has all the advantages combined from asynchronous and synchronous loading. The development flow is simple:

### Step 1: Start writing your application using synchronous approach. Ext.Loader will automatically fetch all
 dependencies on demand as they're needed during run-time. For example: ###

    Ext.onReady(function(){
        var window = Ext.createWidget('window', {
            width: 500,
            height: 300,
            layout: {
                type: 'border',
                padding: 5
            },
            title: 'Hello Dialog',
            items: [{
                title: 'Navigation',
                collapsible: true,
                region: 'west',
                width: 200,
                html: 'Hello',
                split: true
            }, {
                title: 'TabPanel',
                region: 'center'
            }]
        });

        window.show();
    })

### Step 2: Along the way, when you need better debugging ability, watch the console for warnings like these: ###

    [Ext.Loader] Synchronously loading 'Ext.window.Window'; consider adding Ext.require('Ext.window.Window') before your application's code
    ClassManager.js:432
    [Ext.Loader] Synchronously loading 'Ext.layout.container.Border'; consider adding Ext.require('Ext.layout.container.Border') before your application's code

Simply copy and paste the suggested code above `Ext.onReady`, i.e:

    Ext.require('Ext.window.Window');
    Ext.require('Ext.layout.container.Border');

    Ext.onReady(...);

Everything should now load via asynchronous mode.

# Deployment #

It's important to note that dynamic loading should only be used during development on your local machines.
During production, all dependencies should be combined into one single JavaScript file. Ext.Loader makes
the whole process of transitioning from / to between development / maintenance and production as easy as
possible. Internally {@link Ext.Loader#history Ext.Loader.history} maintains the list of all dependencies your application
needs in the exact loading sequence. It's as simple as concatenating all files in this array into one,
then include it on top of your application.

This process will be automated with Sencha Command, to be released and documented towards Ext JS 4 Final.

/**
 * @class Ext.Error
 * @private
 * @extends Error

A wrapper class for the native JavaScript Error object that adds a few useful capabilities for handling
errors in an Ext application. When you use Ext.Error to {@link #raise} an error from within any class that
uses the Ext 4 class system, the Error class can automatically add the source class and method from which
the error was raised. It also includes logic to automatically log the eroor to the console, if available, 
with additional metadata about the error. In all cases, the error will always be thrown at the end so that
execution will halt.

Ext.Error also offers a global error {@link #handle handling} method that can be overridden in order to 
handle application-wide errors in a single spot. You can optionally {@link #ignore} errors altogether,
although in a real application it's usually a better idea to override the handling function and perform
logging or some other method of reporting the errors in a way that is meaningful to the application.

At its simplest you can simply raise an error as a simple string from within any code:

#Example usage:#

    Ext.Error.raise('Something bad happened!');
    
If raised from plain JavaScript code, the error will be logged to the console (if available) and the message
displayed. In most cases however you'll be raising errors from within a class, and it may often be useful to add
additional metadata about the error being raised.  The {@link #raise} method can also take a config object.
In this form the `msg` attribute becomes the error description, and any other data added to the config gets
added to the error object and, if the console is available, logged to the console for inspection.

#Example usage:#
 
    Ext.define('Ext.Foo', {
        doSomething: function(option){
            if (someCondition === false) {
                Ext.Error.raise({
                    msg: 'You cannot do that!',
                    option: option,   // whatever was passed into the method
                    'error code': 100 // other arbitrary info
                });
            }
        }
    });

If a console is available (that supports the `console.dir` function) you'll see console output like:

    An error was raised with the following data:
    option:         Object { foo: "bar"}
        foo:        "bar"
    error code:     100
    msg:            "You cannot do that!"
    sourceClass:   "Ext.Foo"
    sourceMethod:  "doSomething"
    
    uncaught exception: You cannot do that!

As you can see, the error will report exactly where it was raised and will include as much information as the 
raising code can usefully provide.

If you want to handle all application errors globally you can simply override the static {@link handle} method
and provide whatever handling logic you need. If the method returns true then the error is considered handled
and will not be thrown to the browser. If anything but true is returned then the error will be thrown normally.

#Example usage:#

    Ext.Error.handle = function(err) {
        if (err.someProperty == 'NotReallyAnError') {
            // maybe log something to the application here if applicable
            return true;
        }
        // any non-true return value (including none) will cause the error to be thrown
    }

be preferable to supply a custom error {@link #handle handling} function instead.

/**
 * @class Ext

 The Ext namespace (global object) encapsulates all classes, singletons, and utility methods provided by Sencha's libraries.</p>
 Most user interface Components are at a lower level of nesting in the namespace, but many common utility functions are provided
 as direct properties of the Ext namespace.

 Also many frequently used methods from other classes are provided as shortcuts within the Ext namespace.
 For example {@link Ext#getCmp Ext.getCmp} aliases {@link Ext.ComponentManager#get Ext.ComponentManager.get}.

 Many applications are initiated with {@link Ext#onReady Ext.onReady} which is called once the DOM is ready.
 This ensures all scripts have been loaded, preventing dependency issues. For example

     Ext.onReady(function(){
         new Ext.Component({
             renderTo: document.body,
             html: 'DOM ready!'
         });
     });

/**
 * @class Ext.util.Format

This class is a centralized place for formatting functions inside the library. It includes
functions to format various different types of data, such as text, dates and numeric values.

__Localization__
This class contains several options for localization. These can be set once the library has loaded,
all calls to the functions from that point will use the locale settings that were specified.
Options include:
- thousandSeparator
- decimalSeparator
- currenyPrecision
- currencySign
- currencyAtEnd
This class also uses the default date format defined here: {@link Ext.date#defaultFormat}.

__Using with renderers__
There are two helper functions that return a new function that can be used in conjunction with 
grid renderers:

    columns: [{
        dataIndex: 'date',
        renderer: Ext.util.Format.dateRenderer('Y-m-d')
    }, {
        dataIndex: 'time',
        renderer: Ext.util.Format.numberRenderer('0.000')
    }]
    
Functions that only take a single argument can also be passed directly:
    columns: [{
        dataIndex: 'cost',
        renderer: Ext.util.Format.usMoney
    }, {
        dataIndex: 'productCode',
        renderer: Ext.util.Format.uppercase
    }]
    
__Using with XTemplates__
XTemplates can also directly use Ext.util.Format functions:

    new Ext.XTemplate([
        'Date: {startDate:date("Y-m-d")}',
        'Cost: {cost:usMoney}'
    ]);

/**
 * @class Ext.core.DomHelper
 * <p>The DomHelper class provides a layer of abstraction from DOM and transparently supports creating
 * elements via DOM or using HTML fragments. It also has the ability to create HTML fragment templates
 * from your DOM building code.</p>
 *
 * <p><b><u>DomHelper element specification object</u></b></p>
 * <p>A specification object is used when creating elements. Attributes of this object
 * are assumed to be element attributes, except for 4 special attributes:
 * <div class="mdetail-params"><ul>
 * <li><b><tt>tag</tt></b> : <div class="sub-desc">The tag name of the element</div></li>
 * <li><b><tt>children</tt></b> : or <tt>cn</tt><div class="sub-desc">An array of the
 * same kind of element definition objects to be created and appended. These can be nested
 * as deep as you want.</div></li>
 * <li><b><tt>cls</tt></b> : <div class="sub-desc">The class attribute of the element.
 * This will end up being either the "class" attribute on a HTML fragment or className
 * for a DOM node, depending on whether DomHelper is using fragments or DOM.</div></li>
 * <li><b><tt>html</tt></b> : <div class="sub-desc">The innerHTML for the element</div></li>
 * </ul></div></p>
 *
 * <p><b><u>Insertion methods</u></b></p>
 * <p>Commonly used insertion methods:
 * <div class="mdetail-params"><ul>
 * <li><b><tt>{@link #append}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #insertBefore}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #insertAfter}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #overwrite}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #createTemplate}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #insertHtml}</tt></b> : <div class="sub-desc"></div></li>
 * </ul></div></p>
 *
 * <p><b><u>Example</u></b></p>
 * <p>This is an example, where an unordered list with 3 children items is appended to an existing
 * element with id <tt>'my-div'</tt>:<br>
 <pre><code>
var dh = Ext.core.DomHelper; // create shorthand alias
// specification object
var spec = {
    id: 'my-ul',
    tag: 'ul',
    cls: 'my-list',
    // append children after creating
    children: [     // may also specify 'cn' instead of 'children'
        {tag: 'li', id: 'item0', html: 'List Item 0'},
        {tag: 'li', id: 'item1', html: 'List Item 1'},
        {tag: 'li', id: 'item2', html: 'List Item 2'}
    ]
};
var list = dh.append(
    'my-div', // the context element 'my-div' can either be the id or the actual node
    spec      // the specification object
);
 </code></pre></p>
 * <p>Element creation specification parameters in this class may also be passed as an Array of
 * specification objects. This can be used to insert multiple sibling nodes into an existing
 * container very efficiently. For example, to add more list items to the example above:<pre><code>
dh.append('my-ul', [
    {tag: 'li', id: 'item3', html: 'List Item 3'},
    {tag: 'li', id: 'item4', html: 'List Item 4'}
]);
 * </code></pre></p>
 *
 * <p><b><u>Templating</u></b></p>
 * <p>The real power is in the built-in templating. Instead of creating or appending any elements,
 * <tt>{@link #createTemplate}</tt> returns a Template object which can be used over and over to
 * insert new elements. Revisiting the example above, we could utilize templating this time:
 * <pre><code>
// create the node
var list = dh.append('my-div', {tag: 'ul', cls: 'my-list'});
// get template
var tpl = dh.createTemplate({tag: 'li', id: 'item{0}', html: 'List Item {0}'});

for(var i = 0; i < 5, i++){
    tpl.append(list, [i]); // use template to append to the actual node
}
 * </code></pre></p>
 * <p>An example using a template:<pre><code>
var html = '<a id="{0}" href="{1}" class="nav">{2}</a>';

var tpl = new Ext.core.DomHelper.createTemplate(html);
tpl.append('blog-roll', ['link1', 'http://www.edspencer.net/', "Ed&#39;s Site"]);
tpl.append('blog-roll', ['link2', 'http://www.dustindiaz.com/', "Dustin&#39;s Site"]);
 * </code></pre></p>
 *
 * <p>The same example using named parameters:<pre><code>
var html = '<a id="{id}" href="{url}" class="nav">{text}</a>';

var tpl = new Ext.core.DomHelper.createTemplate(html);
tpl.append('blog-roll', {
    id: 'link1',
    url: 'http://www.edspencer.net/',
    text: "Ed&#39;s Site"
});
tpl.append('blog-roll', {
    id: 'link2',
    url: 'http://www.dustindiaz.com/',
    text: "Dustin&#39;s Site"
});
 * </code></pre></p>
 *
 * <p><b><u>Compiling Templates</u></b></p>
 * <p>Templates are applied using regular expressions. The performance is great, but if
 * you are adding a bunch of DOM elements using the same template, you can increase
 * performance even further by {@link Ext.Template#compile "compiling"} the template.
 * The way "{@link Ext.Template#compile compile()}" works is the template is parsed and
 * broken up at the different variable points and a dynamic function is created and eval'ed.
 * The generated function performs string concatenation of these parts and the passed
 * variables instead of using regular expressions.
 * <pre><code>
var html = '<a id="{id}" href="{url}" class="nav">{text}</a>';

var tpl = new Ext.core.DomHelper.createTemplate(html);
tpl.compile();

//... use template like normal
 * </code></pre></p>
 *
 * <p><b><u>Performance Boost</u></b></p>
 * <p>DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead
 * of DOM can significantly boost performance.</p>
 * <p>Element creation specification parameters may also be strings. If {@link #useDom} is <tt>false</tt>,
 * then the string is used as innerHTML. If {@link #useDom} is <tt>true</tt>, a string specification
 * results in the creation of a text node. Usage:</p>
 * <pre><code>
Ext.core.DomHelper.useDom = true; // force it to use DOM; reduces performance
 * </code></pre>
 * @singleton

/**
 * @class Ext.DomQuery
Provides high performance selector/xpath processing by compiling queries into reusable functions. New pseudo classes and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in).
<p>
DomQuery supports most of the <a href="http://www.w3.org/TR/2005/WD-css3-selectors-20051215/#selectors">CSS3 selectors spec</a>, along with some custom selectors and basic XPath.</p>

<p>
All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example "div.foo:nth-child(odd)[@foo=bar].bar:first" would be a perfectly valid selector. Node filters are processed in the order in which they appear, which allows you to optimize your queries for your document structure.
</p>
<h4>Element Selectors:</h4>
<ul class="list">
    <li> <b>*</b> any element</li>
    <li> <b>E</b> an element with the tag E</li>
    <li> <b>E F</b> All descendent elements of E that have the tag F</li>
    <li> <b>E > F</b> or <b>E/F</b> all direct children elements of E that have the tag F</li>
    <li> <b>E + F</b> all elements with the tag F that are immediately preceded by an element with the tag E</li>
    <li> <b>E ~ F</b> all elements with the tag F that are preceded by a sibling element with the tag E</li>
</ul>
<h4>Attribute Selectors:</h4>
<p>The use of &#64; and quotes are optional. For example, div[&#64;foo='bar'] is also a valid attribute selector.</p>
<ul class="list">
    <li> <b>E[foo]</b> has an attribute "foo"</li>
    <li> <b>E[foo=bar]</b> has an attribute "foo" that equals "bar"</li>
    <li> <b>E[foo^=bar]</b> has an attribute "foo" that starts with "bar"</li>
    <li> <b>E[foo$=bar]</b> has an attribute "foo" that ends with "bar"</li>
    <li> <b>E[foo*=bar]</b> has an attribute "foo" that contains the substring "bar"</li>
    <li> <b>E[foo%=2]</b> has an attribute "foo" that is evenly divisible by 2</li>
    <li> <b>E[foo!=bar]</b> attribute "foo" does not equal "bar"</li>
</ul>
<h4>Pseudo Classes:</h4>
<ul class="list">
    <li> <b>E:first-child</b> E is the first child of its parent</li>
    <li> <b>E:last-child</b> E is the last child of its parent</li>
    <li> <b>E:nth-child(<i>n</i>)</b> E is the <i>n</i>th child of its parent (1 based as per the spec)</li>
    <li> <b>E:nth-child(odd)</b> E is an odd child of its parent</li>
    <li> <b>E:nth-child(even)</b> E is an even child of its parent</li>
    <li> <b>E:only-child</b> E is the only child of its parent</li>
    <li> <b>E:checked</b> E is an element that is has a checked attribute that is true (e.g. a radio or checkbox) </li>
    <li> <b>E:first</b> the first E in the resultset</li>
    <li> <b>E:last</b> the last E in the resultset</li>
    <li> <b>E:nth(<i>n</i>)</b> the <i>n</i>th E in the resultset (1 based)</li>
    <li> <b>E:odd</b> shortcut for :nth-child(odd)</li>
    <li> <b>E:even</b> shortcut for :nth-child(even)</li>
    <li> <b>E:contains(foo)</b> E's innerHTML contains the substring "foo"</li>
    <li> <b>E:nodeValue(foo)</b> E contains a textNode with a nodeValue that equals "foo"</li>
    <li> <b>E:not(S)</b> an E element that does not match simple selector S</li>
    <li> <b>E:has(S)</b> an E element that has a descendent that matches simple selector S</li>
    <li> <b>E:next(S)</b> an E element whose next sibling matches simple selector S</li>

        /**
Object hash of "pseudo class" filter functions which are used when filtering selections. 
Each function is passed two parameters:

- **c** : Array
    An Array of DOM elements to filter.
    
- **v** : String
    The argument (if any) supplied in the selector.

A filter function returns an Array of DOM elements which conform to the pseudo class.
In addition to the provided pseudo classes listed above such as `first-child` and `nth-child`,
developers may add additional, custom psuedo class filters to select elements according to application-specific requirements.

For example, to filter `a` elements to only return links to __external__ resources:

    Ext.DomQuery.pseudos.external = function(c, v){
        var r = [], ri = -1;
        for(var i = 0, ci; ci = c[i]; i++){
            // Include in result set only if it's a link to an external resource
            if(ci.hostname != location.hostname){
                r[++ri] = ci;
            }
        }
        return r;
    };

Then external links could be gathered with the following statement:

    var externalLinks = Ext.select("a:external");

/**
 * @class Ext.core.Element
 * <p>Encapsulates a DOM element, adding simple DOM manipulation facilities, normalizing for browser differences.</p>
 * <p>All instances of this class inherit the methods of {@link Ext.fx.Anim} making visual effects easily available to all DOM elements.</p>
 * <p>Note that the events documented in this class are not Ext events, they encapsulate browser events. To
 * access the underlying browser event, see {@link Ext.EventObject#browserEvent}. Some older
 * browsers may not support the full range of events. Which events are supported is beyond the control of ExtJs.</p>
 * Usage:<br>
<pre><code>
// by id
var el = Ext.get("my-div");

// by DOM element reference
var el = Ext.get(myDivElement);
</code></pre>
 * <b>Animations</b><br />
 * <p>When an element is manipulated, by default there is no animation.</p>
 * <pre><code>
var el = Ext.get("my-div");

// no animation
el.setWidth(100);
 * </code></pre>
 * <p>Many of the functions for manipulating an element have an optional "animate" parameter.  This
 * parameter can be specified as boolean (<tt>true</tt>) for default animation effects.</p>
 * <pre><code>
// default animation
el.setWidth(100, true);
 * </code></pre>
 *
 * <p>To configure the effects, an object literal with animation options to use as the Element animation
 * configuration object can also be specified. Note that the supported Element animation configuration
 * options are a subset of the {@link Ext.fx.Anim} animation options specific to Fx effects.  The supported
 * Element animation configuration options are:</p>
<pre>
Option    Default   Description
--------- --------  ---------------------------------------------
{@link Ext.fx.Anim#duration duration}  .35       The duration of the animation in seconds
{@link Ext.fx.Anim#easing easing}    easeOut   The easing method
{@link Ext.fx.Anim#callback callback}  none      A function to execute when the anim completes
{@link Ext.fx.Anim#scope scope}     this      The scope (this) of the callback function
</pre>
 *
 * <pre><code>
// Element animation options object
var opt = {
    {@link Ext.fx.Anim#duration duration}: 1,
    {@link Ext.fx.Anim#easing easing}: 'elasticIn',
    {@link Ext.fx.Anim#callback callback}: this.foo,
    {@link Ext.fx.Anim#scope scope}: this
};
// animation with some options set
el.setWidth(100, opt);
 * </code></pre>
 * <p>The Element animation object being used for the animation will be set on the options
 * object as "anim", which allows you to stop or manipulate the animation. Here is an example:</p>
 * <pre><code>
// using the "anim" property to get the Anim object
if(opt.anim.isAnimated()){
    opt.anim.stop();
}
 * </code></pre>
 * <p>Also see the <tt>{@link #animate}</tt> method for another animation technique.</p>
 * <p><b> Composite (Collections of) Elements</b></p>
 * <p>For working with collections of Elements, see {@link Ext.CompositeElement}</p>
 * @constructor Create a new Element directly.
 * @param {String/HTMLElement} element
 * @param {Boolean} forceNew (optional) By default the constructor checks to see if there is already an instance of this element in the cache and if there is it returns the same instance. This will skip that check (useful for extending this class).

     * <b>Combining Options</b><br>
     * In the following examples, the shorthand form {@link #on} is used rather than the more verbose

     * types of listeners:<br>
     * <br>
     * A delayed, one-time listener that auto stops the event and adds a custom argument (forumId) to the
     * options object. The options object is available as the third parameter in the handler function.<div style="margin: 5px 20px 20px;">
     * Code:<pre><code>
el.on('click', this.onClick, this, {
    single: true,
    delay: 100,
    stopEvent : true,
    forumId: 4
});</code></pre></p>
     * <p>
     * <b>Attaching multiple handlers in 1 call</b><br>
     * The method also allows for a single argument to be passed which is a config object containing properties
     * which specify multiple handlers.</p>
     * <p>
     * Code:<pre><code>
el.on({
    'click' : {
        fn: this.onClick,
        scope: this,
        delay: 100
    },
    'mouseover' : {
        fn: this.onMouseOver,
        scope: this
    },
    'mouseout' : {
        fn: this.onMouseOut,
        scope: this
    }
});</code></pre>
     * <p>
     * Or a shorthand syntax:<br>
     * Code:<pre><code></p>
el.on({
    'click' : this.onClick,
    'mouseover' : this.onMouseOver,
    'mouseout' : this.onMouseOut,
    scope: this
});
     * </code></pre></p>
     * <p><b>delegate</b></p>
     * <p>This is a configuration option that you can pass along when registering a handler for
     * an event to assist with event delegation. Event delegation is a technique that is used to
     * reduce memory consumption and prevent exposure to memory-leaks. By registering an event
     * for a container element as opposed to each element within a container. By setting this
     * configuration option to a simple selector, the target element will be filtered to look for
     * a descendant of the target.
     * For example:<pre><code>
// using this markup:
&lt;div id='elId'>
    &lt;p id='p1'>paragraph one&lt;/p>
    &lt;p id='p2' class='clickable'>paragraph two&lt;/p>
    &lt;p id='p3'>paragraph three&lt;/p>
&lt;/div>
// utilize event delegation to registering just one handler on the container element:
el = Ext.get('elId');
el.on(
    'click',
    function(e,t) {
        // handle click
        console.info(t.id); // 'p2'
    },
    this,
    {
        // filter the target element to be a descendant with the class 'clickable'
        delegate: '.clickable'
    }
);

 * @class Ext.util.DelayedTask
 * 
 * The DelayedTask class provides a convenient way to "buffer" the execution of a method,
 * performing setTimeout where a new timeout cancels the old timeout. When called, the
 * task will wait the specified time period before executing. If durng that time period,
 * the task is called again, the original call will be cancelled. This continues so that
 * the function is only called a single time for each iteration.
 * 
 * This method is especially useful for things like detecting whether a user has finished
 * typing in a text field. An example would be performing validation on a keypress. You can
 * use this class to buffer the keypress events for a certain number of milliseconds, and
 * perform only if they stop for that amount of time.  
 * 
 * ## Usage
 * 
 *     var task = new Ext.util.DelayedTask(function(){
 *         alert(Ext.getDom('myInputField').value.length);
 *     });
 *     
 *     // Wait 500ms before calling our function. If the user presses another key
 *     // during that 500ms, it will be cancelled and we'll wait another 500ms.
 *     Ext.get('myInputField').on('keypress', function(){
 *         task.{@link #delay}(500);
 *     });
 * 
 * Note that we are using a DelayedTask here to illustrate a point. The configuration
 * option `buffer` for {@link Ext.util.Observable#addListener addListener/on} will
 * also setup a delayed task for you to buffer events.
 * 
 * @constructor The parameters to this constructor serve as defaults and are not required.
 * @param {Function} fn (optional) The default function to call.
 * @param {Object} scope The default scope (The <code><b>this</b></code> reference) in which the
 * function is called. If not specified, <code>this</code> will refer to the browser window.
 * @param {Array} args (optional) The default Array of arguments.

/**
 * @class Ext.EventObject

Just as {@link Ext.core.Element} wraps around a native DOM node, Ext.EventObject
wraps the browser's native event-object normalizing cross-browser differences,
such as which mouse button is clicked, keys pressed, mechanisms to stop
event-propagation along with a method to prevent default actions from taking place.

For example:

    function handleClick(e, t){ // e is not a standard event object, it is a Ext.EventObject
        e.preventDefault();
        var target = e.getTarget(); // same as t (the target HTMLElement)
        ...
    }

    var myDiv = {@link Ext#get Ext.get}("myDiv");  // get reference to an {@link Ext.core.Element}
    myDiv.on(         // 'on' is shorthand for addListener
        "click",      // perform an action on click of myDiv
        handleClick   // reference to the action handler
    );

    // other methods to do the same:
    Ext.EventManager.on("myDiv", 'click', handleClick);
    Ext.EventManager.addListener("myDiv", 'click', handleClick);

     *   <li><b>One anchor (deprecated)</b>: The passed anchor position is used as the target element's anchor point.
     *       The element being aligned will position its top-left corner (tl) to that point.  <i>This method has been

/**
 * @class Ext.util.Animate
 * This animation class is a mixin.
 * 
 * Ext.util.Animate provides an API for the creation of animated transitions of properties and styles.  
 * This class is used as a mixin and currently applied to {@link Ext.core.Element}, {@link Ext.CompositeElement}, 
 * {@link Ext.draw.Sprite}, {@link Ext.draw.CompositeSprite}, and {@link Ext.Component}.  Note that Components 
 * have a limited subset of what attributes can be animated such as top, left, x, y, height, width, and 
 * opacity (color, paddings, and margins can not be animated).
 * 
 * ## Animation Basics
 * 
 * All animations require three things - `easing`, `duration`, and `to` (the final end value for each property) 
 * you wish to animate. Easing and duration are defaulted values specified below.
 * Easing describes how the intermediate values used during a transition will be calculated. 
 * {@link Ext.fx.Anim#easing Easing} allows for a transition to change speed over its duration.
 * You may use the defaults for easing and duration, but you must always set a 
 * {@link Ext.fx.Anim#to to} property which is the end value for all animations.  
 * 
 * Popular element 'to' configurations are:
 * 
 *  - opacity
 *  - x
 *  - y
 *  - color
 *  - height
 *  - width 
 * 
 * Popular sprite 'to' configurations are:
 * 
 *  - translation
 *  - path
 *  - scale
 *  - stroke
 *  - rotation
 * 
 * The default duration for animations is 250 (which is a 1/4 of a second).  Duration is denoted in 
 * milliseconds.  Therefore 1 second is 1000, 1 minute would be 60000, and so on. The default easing curve 
 * used for all animations is 'ease'.  Popular easing functions are included and can be found in {@link Ext.fx.Anim#easing Easing}.
 * 
 * For example, a simple animation to fade out an element with a default easing and duration:
 * 
 *     var p1 = Ext.get('myElementId');
 * 
 *     p1.animate({
 *         to: {
 *             opacity: 0
 *         }
 *     });
 * 
 * To make this animation fade out in a tenth of a second:
 * 
 *     var p1 = Ext.get('myElementId');
 * 
 *     p1.animate({
 *        duration: 100,
 *         to: {
 *             opacity: 0
 *         }
 *     });
 * 
 * ## Animation Queues
 * 
 * By default all animations are added to a queue which allows for animation via a chain-style API.
 * For example, the following code will queue 4 animations which occur sequentially (one right after the other):
 * 
 *     p1.animate({
 *         to: {
 *             x: 500
 *         }
 *     }).animate({
 *         to: {
 *             y: 150
 *         }
 *     }).animate({
 *         to: {
 *             backgroundColor: '#f00'  //red
 *         }
 *     }).animate({
 *         to: {
 *             opacity: 0
 *         }
 *     });
 * 
 * You can change this behavior by calling the {@link Ext.util.Animate#syncFx syncFx} method and all 
 * subsequent animations for the specified target will be run concurrently (at the same time).
 * 
 *     p1.syncFx();  //this will make all animations run at the same time
 * 
 *     p1.animate({
 *         to: {
 *             x: 500
 *         }
 *     }).animate({
 *         to: {
 *             y: 150
 *         }
 *     }).animate({
 *         to: {
 *             backgroundColor: '#f00'  //red
 *         }
 *     }).animate({
 *         to: {
 *             opacity: 0
 *         }
 *     });
 * 
 * This works the same as:
 * 
 *     p1.animate({
 *         to: {
 *             x: 500,
 *             y: 150,
 *             backgroundColor: '#f00'  //red
 *             opacity: 0
 *         }
 *     });
 * 
 * The {@link Ext.util.Animate#stopAnimation stopAnimation} method can be used to stop any 
 * currently running animations and clear any queued animations. 
 * 
 * ## Animation Keyframes
 *
 * You can also set up complex animations with {@link Ext.fx.Anim#keyframe keyframe} which follows the 
 * CSS3 Animation configuration pattern. Note rotation, translation, and scaling can only be done for sprites. 
 * The previous example can be written with the following syntax:
 * 
 *     p1.animate({
 *         duration: 1000,  //one second total
 *         keyframes: {
 *             25: {     //from 0 to 250ms (25%)
 *                 x: 0
 *             },
 *             50: {   //from 250ms to 500ms (50%)
 *                 y: 0
 *             },
 *             75: {  //from 500ms to 750ms (75%)
 *                 backgroundColor: '#f00'  //red
 *             },
 *             100: {  //from 750ms to 1sec
 *                 opacity: 0
 *             }
 *         }
 *     });
 * 
 * ## Animation Events
 * 
 * Each animation you create has events for {@link Ext.fx.Anim#beforeanimation beforeanimation}, 
 * {@link Ext.fx.Anim#afteranimate afteranimate}, and {@link Ext.fx.Anim#lastframe lastframe}.  
 * Keyframed animations adds an additional {@link Ext.fx.Animator#keyframe keyframe} event which 
 * fires for each keyframe in your animation.
 * 
 * All animations support the {@link Ext.util.Observable#listeners listeners} configuration to attact functions to these events.
 *    
 *     startAnimate: function() {
 *         var p1 = Ext.get('myElementId');
 *         p1.animate({
 *            duration: 100,
 *             to: {
 *                 opacity: 0
 *             },
 *             listeners: {
 *                 beforeanimate:  function() {
 *                     // Execute my custom method before the animation
 *                     this.myBeforeAnimateFn();
 *                 },
 *                 afteranimate: function() {
 *                     // Execute my custom method after the animation
 *                     this.myAfterAnimateFn();
 *                 },
 *                 scope: this
 *         });
 *     },
 *     myBeforeAnimateFn: function() {
 *       // My custom logic
 *     },
 *     myAfterAnimateFn: function() {
 *       // My custom logic
 *     }
 * 
 * Due to the fact that animations run asynchronously, you can determine if an animation is currently 
 * running on any target by using the {@link Ext.util.Animate#getActiveAnimation getActiveAnimation} 
 * method.  This method will return false if there are no active animations or return the currently 
 * running {@link Ext.fx.Anim} instance.
 * 
 * In this example, we're going to wait for the current animation to finish, then stop any other 
 * queued animations before we fade our element's opacity to 0:
 * 
 *     var curAnim = p1.getActiveAnimation();
 *     if (curAnim) {
 *         curAnim.on('afteranimate', function() {
 *             p1.stopAnimation();
 *             p1.animate({
 *                 to: {
 *                     opacity: 0
 *                 }
 *             });
 *         });
 *     }

     * </ul>
     * <p>For example, to animate a Window to a new size, ensuring that its internal layout, and any shadow is correct:</p>
     * <pre><code>
myWindow = Ext.create('Ext.window.Window', {
    title: 'Test Component animation',
    width: 500,
    height: 300,
    layout: {
        type: 'hbox',
        align: 'stretch'
    },
    items: [{
        title: 'Left: 33%',
        margins: '5 0 5 5',
        flex: 1
    }, {
        title: 'Left: 66%',
        margins: '5 5 5 5',
        flex: 2
    }]
});
myWindow.show();
myWindow.header.el.on('click', function() {
    myWindow.animate({
        to: {
            width: (myWindow.getWidth() == 500) ? 700 : 500,
            height: (myWindow.getHeight() == 300) ? 400 : 300,
        }
    });
});
</code></pre>
     * <p>For performance reasons, by default, the internal layout is only updated when the Window reaches its final <code>"to"</code> size. If dynamic updating of the Window's child
     * Components is required, then configure the animation with <code>dynamic: true</code> and the two child items will maintain their proportions during the animation.</p>

address: '5 Cups Drive',
city: 'Palo Alto',
state: 'CA',

drinks: ['Coffee', 'Soda', 'Water'],
kids: [{

    },{
        name: 'Solomon',
        age:0
}]
};
 </code></pre>
 * </div>
 * </li>
 *
 *
 * <li><b><u>Auto filling of arrays</u></b>
 * <div class="sub-desc">
 * <p>The <b><tt>tpl</tt></b> tag and the <b><tt>for</tt></b> operator are used
 * to process the provided data object:
 * <ul>
 * <li>If the value specified in <tt>for</tt> is an array, it will auto-fill,
 * repeating the template block inside the <tt>tpl</tt> tag for each item in the
 * array.</li>
 * <li>If <tt>for="."</tt> is specified, the data object provided is examined.</li>
 * <li>While processing an array, the special variable <tt>{#}</tt>
 * will provide the current array index + 1 (starts at 1, not 0).</li>
 * </ul>
 * </p>
 * <pre><code>
&lt;tpl <b>for</b>=".">...&lt;/tpl>       // loop through array at root node
&lt;tpl <b>for</b>="foo">...&lt;/tpl>     // loop through array at foo node
&lt;tpl <b>for</b>="foo.bar">...&lt;/tpl> // loop through array at foo.bar node
 </code></pre>
 * Using the sample data above:
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Kids: ',
    '&lt;tpl <b>for</b>=".">',       // process the data.kids node
        '&lt;p>{#}. {name}&lt;/p>',  // use current array index to autonumber
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data.kids); // pass the kids property of the data object
 </code></pre>
 * <p>An example illustrating how the <b><tt>for</tt></b> property can be leveraged
 * to access specified members of the provided data object to populate the template:</p>
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Title: {title}&lt;/p>',
    '&lt;p>Company: {company}&lt;/p>',

        '&lt;p>{name}&lt;/p>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);  // pass the root node of the data object
 </code></pre>
 * <p>Flat arrays that contain values (and not objects) can be auto-rendered
 * using the special <b><tt>{.}</tt></b> variable inside a loop.  This variable
 * will represent the value of the array at the current index:</p>
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>{name}\&#39;s favorite beverages:&lt;/p>',
    '&lt;tpl for="drinks">',
        '&lt;div> - {.}&lt;/div>',
    '&lt;/tpl>'
);
tpl.overwrite(panel.body, data);
 </code></pre>
 * <p>When processing a sub-template, for example while looping through a child array,
 * you can access the parent object's members via the <b><tt>parent</tt></b> object:</p>
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',

 * </div>

 *
 *
 * <li><b><u>Conditional processing with basic comparison operators</u></b>
 * <div class="sub-desc">
 * <p>The <b><tt>tpl</tt></b> tag and the <b><tt>if</tt></b> operator are used
 * to provide conditional checks for deciding whether or not to render specific

 *
 * <li><b><u>Execute arbitrary inline code with special built-in template variables</u></b>
 * <div class="sub-desc">
 * <p>Anything between <code>{[ ... ]}</code> is considered code to be executed
 * in the scope of the template. There are some special variables available in that code:

 * scope changing sub-templates, you can change what <tt>values</tt> is.</li>
 * <li><b><tt>parent</tt></b>: The scope (values) of the ancestor template.</li>
 * <li><b><tt>xindex</tt></b>: If you are in a looping template, the index of the

 * <li><b><tt>xcount</tt></b>: If you are in a looping template, the total length

/**
 * @class Ext.ComponentLoader
 * @extends Ext.ElementLoader
 * 
 * This class is used to load content via Ajax into a {@link Ext.Component}. In general 
 * this class will not be instanced directly, rather a loader configuration will be passed to the
 * constructor of the {@link Ext.Component}.
 * 
 * ## HTML Renderer
 * By default, the content loaded will be processed as raw html. The response text
 * from the request is taken and added to the component. This can be used in
 * conjunction with the {@link #scripts} option to execute any inline scripts in
 * the resulting content. Using this renderer has the same effect as passing the
 * {@link Ext.Component#html} configuration option.
 * 
 * ## Data Renderer
 * This renderer allows content to be added by using JSON data and a {@link Ext.XTemplate}.
 * The content received from the response is passed to the {@link Ext.Component#update} method.
 * This content is run through the attached {@link Ext.Component#tpl} and the data is added to
 * the Component. Using this renderer has the same effect as using the {@link Ext.Component#data}
 * configuration in conjunction with a {@link Ext.Component#tpl}.
 * 
 * ## Component Renderer
 * This renderer can only be used with a {@link Ext.Container} and subclasses. It allows for
 * Components to be loaded remotely into a Container. The response is expected to be a single/series of
 * {@link Ext.Component} configuration objects. When the response is received, the data is decoded
 * and then passed to {@link Ext.Container#add}. Using this renderer has the same effect as specifying
 * the {@link Ext.Container#items} configuration on a Container. 
 * 
 * ## Custom Renderer
 * A custom function can be passed to handle any other special case, see the {@link #renderer} option.
 * 
 * ## Example Usage
 *     new Ext.Component({
 *         tpl: '{firstName} - {lastName}',
 *         loader: {
 *             url: 'myPage.php',
 *             renderer: 'data',
 *             params: {
 *                 userId: 1
 *             }
 *         }

/**
 * @class Ext.Ajax
 * @singleton
 * @markdown
 * @extends Ext.data.Connection

A singleton instance of an {@link Ext.data.Connection}. This class
is used to communicate with your server side code. It can be used as follows:

    Ext.Ajax.request({
        url: 'page.php',
        params: {
            id: 1
        },
        success: function(response){
            var text = response.responseText;
            // process server response here
        }
    });

Default options for all requests can be set be changing a property on the Ext.Ajax class:

    Ext.Ajax.timeout = 60000; // 60 seconds

Any options specified in the request method for the Ajax request will override any
defaults set on the Ext.Ajax class. In the code sample below, the timeout for the
request will be 60 seconds.

    Ext.Ajax.timeout = 120000; // 120 seconds
    Ext.Ajax.request({
        url: 'page.aspx',
        timeout: 60000
    });

In general, this class will be used for all Ajax requests in your application.
The main reason for creating a separate {@link Ext.data.Connection} is for a
series of requests that share common settings that are different to all other
requests in the application.

 * @class Ext.data.Association
 * @extends Object
 *
 * <p>Associations enable you to express relationships between different {@link Ext.data.Model Models}. Let's say we're
 * writing an ecommerce system where Users can make Orders - there's a relationship between these Models that we can
 * express like this:</p>
 *
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email'],

    hasMany: {model: 'Order', name: 'orders'}
});

Ext.define('Order', {
    extend: 'Ext.data.Model',
    fields: ['id', 'user_id', 'status', 'price'],

    belongsTo: 'User'
});
</code></pre>
 *
 * <p>We've set up two models - User and Order - and told them about each other. You can set up as many associations on
 * each Model as you need using the two default types - {@link Ext.data.HasManyAssociation hasMany} and
 * {@link Ext.data.BelongsToAssociation belongsTo}. There's much more detail on the usage of each of those inside their
 * documentation pages. If you're not familiar with Models already, {@link Ext.data.Model there is plenty on those too}.</p>

/**
 * @author Ed Spencer
 * @class Ext.ModelManager
 * @extends Ext.AbstractManager

The ModelManager keeps track of all {@link Ext.data.Model} types defined in your application.

__Creating Model Instances__
Model instances can be created by using the {@link #create} function. It is also possible to do
this by using the Model type directly. The following snippets are equivalent:

    Ext.define('User', {
        extend: 'Ext.data.Model',
        fields: ['first', 'last']
    });
    
    // method 1, create through the manager
    Ext.ModelManager.create({
        first: 'Ed',
        last: 'Spencer'
    }, 'User');
    
    // method 2, create on the type directly
    new User({
        first: 'Ed',
        last: 'Spencer'
    });
    
__Accessing Model Types__
A reference to a Model type can be obtained by using the {@link #getModel} function. Since models types
are normal classes, you can access the type directly. The following snippets are equivalent:

    Ext.define('User', {
        extend: 'Ext.data.Model',
        fields: ['first', 'last']
    });
    
    // method 1, access model type through the manager
    var UserType = Ext.ModelManager.getModel('User');
    
    // method 2, reference the type directly
    var UserType = User;

 *             console.log('Initialized Users! This happens before the Application launch function is called');
 *         }
 *     });
 * 
 * The init function is a special method that is called when your application boots. It is called before the 
 * {@link Ext.app.Application Application}'s launch function is executed so gives a hook point to run any code before
 * your Viewport is created.
 * 
 * The init function is a great place to set up how your controller interacts with the view, and is usually used in 
 * conjunction with another Controller function - {@link Ext.app.Controller#control control}. The control function 
 * makes it easy to listen to events on your view classes and take some action with a handler function. Let's update
 * our Users controller to tell us when the panel is rendered:
 * 
 *     Ext.define('MyApp.controller.Users', {
 *         extend: 'Ext.app.Controller',
 * 
 *         init: function() {
 *             this.control({
 *                 'viewport > panel': {
 *                     render: this.onPanelRendered
 *                 }
 *             });
 *         },
 * 
 *         onPanelRendered: function() {
 *             console.log('The panel was rendered');
 *         }
 *     });
 * 
 * We've updated the init function to use this.control to set up listeners on views in our application. The control
 * function uses the new ComponentQuery engine to quickly and easily get references to components on the page. If you
 * are not familiar with ComponentQuery yet, be sure to check out THIS GUIDE for a full explanation. In brief though,
 * it allows us to pass a CSS-like selector that will find every matching component on the page.
 * 
 * In our init function above we supplied 'viewport > panel', which translates to "find me every Panel that is a direct
 * child of a Viewport". We then supplied an object that maps event names (just 'render' in this case) to handler 
 * functions. The overall effect is that whenever any component that matches our selector fires a 'render' event, our 
 * onPanelRendered function is called.
 * 
 * <u>Using refs</u>
 * 
 * One of the most useful parts of Controllers is the new ref system. These use the new {@link Ext.ComponentQuery} to
 * make it really easy to get references to Views on your page. Let's look at an example of this now:
 * 
 * Ext.define('MyApp.controller.Users', {
     extend: 'Ext.app.Controller',

     refs: [
         {
             ref: 'list',
             selector: 'grid'
         }
     ],

     init: function() {
         this.control({
             'button': {
                 click: this.refreshGrid
             }
         });
     },

     refreshGrid: function() {
         this.getList().store.load();
     }
 });
 * 
 * This example assumes the existence of a {@link Ext.grid.Panel Grid} on the page, which contains a single button to 
 * refresh the Grid when clicked. In our refs array, we set up a reference to the grid. There are two parts to this - 
 * the 'selector', which is a {@link Ext.ComponentQuery ComponentQuery} selector which finds any grid on the page and
 * assigns it to the reference 'list'.
 * 
 * By giving the reference a name, we get a number of things for free. The first is the getList function that we use in
 * the refreshGrid method above. This is generated automatically by the Controller based on the name of our ref, which 
 * was capitalized and prepended with get to go from 'list' to 'getList'.
 * 
 * The way this works is that the first time getList is called by your code, the ComponentQuery selector is run and the
 * first component that matches the selector ('grid' in this case) will be returned. All future calls to getList will 
 * use a cached reference to that grid. Usually it is advised to use a specific ComponentQuery selector that will only
 * match a single View in your application (in the case above our selector will match any grid on the page).
 * 
 * Bringing it all together, our init function is called when the application boots, at which time we call this.control
 * to listen to any click on a {@link Ext.button.Button button} and call our refreshGrid function (again, this will 
 * match any button on the page so we advise a more specific selector than just 'button', but have left it this way for
 * simplicity). When the button is clicked we use out getList function to refresh the grid.
 * 
 * You can create any number of refs and control any number of components this way, simply adding more functions to 
 * your Controller as you go. For an example of real-world usage of Controllers see the Feed Viewer example in the 
 * examples/app/feed-viewer folder in the SDK download.
 * 
 * <u>Generated getter methods</u>
 * 
 * Refs aren't the only thing that generate convenient getter methods. Controllers often have to deal with Models and 
 * Stores so the framework offers a couple of easy ways to get access to those too. Let's look at another example:
 * 
 * Ext.define('MyApp.controller.Users', {
     extend: 'Ext.app.Controller',

     models: ['User'],
     stores: ['AllUsers', 'AdminUsers'],

     init: function() {
         var User = this.getUserModel(),
             allUsers = this.getAllUsersStore();

         var ed = new User({name: 'Ed'});
         allUsers.add(ed);
     }
 });
 * 
 * By specifying Models and Stores that the Controller cares about, it again dynamically loads them from the appropriate
 * locations (app/model/User.js, app/store/AllUsers.js and app/store/AdminUsers.js in this case) and creates getter 
 * functions for them all. The example above will create a new User model instance and add it to the AllUsers Store.
 * Of course, you could do anything in this function but in this case we just did something simple to demonstrate the 
 * functionality.
 *

 * @class Ext.data.Types
 * <p>This is s static class containing the system-supplied data types which may be given to a {@link Ext.data.Field Field}.<p/>
 * <p>The properties in this class are used as type indicators in the {@link Ext.data.Field Field} class, so to
 * test whether a Field is of a certain type, compare the {@link Ext.data.Field#type type} property against properties
 * of this class.</p>
 * <p>Developers may add their own application-specific data types to this class. Definition names must be UPPERCASE.
 * each type definition must contain three properties:</p>
 * <div class="mdetail-params"><ul>
 * <li><code>convert</code> : <i>Function</i><div class="sub-desc">A function to convert raw data values from a data block into the data
 * to be stored in the Field. The function is passed the collowing parameters:
 * <div class="mdetail-params"><ul>
 * <li><b>v</b> : Mixed<div class="sub-desc">The data value as read by the Reader, if undefined will use
 * the configured <tt>{@link Ext.data.Field#defaultValue defaultValue}</tt>.</div></li>
 * <li><b>rec</b> : Mixed<div class="sub-desc">The data object containing the row as read by the Reader.
 * Depending on the Reader type, this could be an Array ({@link Ext.data.reader.Array ArrayReader}), an object
 * ({@link Ext.data.reader.Json JsonReader}), or an XML element.</div></li>
 * </ul></div></div></li>
 * <li><code>sortType</code> : <i>Function</i> <div class="sub-desc">A function to convert the stored data into comparable form, as defined by {@link Ext.data.SortTypes}.</div></li>
 * <li><code>type</code> : <i>String</i> <div class="sub-desc">A textual data type name.</div></li>
 * </ul></div>
 * <p>For example, to create a VELatLong field (See the Microsoft Bing Mapping API) containing the latitude/longitude value of a datapoint on a map from a JsonReader data block
 * which contained the properties <code>lat</code> and <code>long</code>, you would define a new data type like this:</p>
 *<pre><code>
// Add a new Field data type which stores a VELatLong object in the Record.
Ext.data.Types.VELATLONG = {
    convert: function(v, data) {
        return new VELatLong(data.lat, data.long);
    },
    sortType: function(v) {
        return v.Latitude;  // When sorting, order by latitude
    },
    type: 'VELatLong'
};
</code></pre>
 * <p>Then, when declaring a Model, use <pre><code>
var types = Ext.data.Types; // allow shorthand type access

/**
 * @author Ed Spencer
 * @class Ext.data.Field
 * @extends Object
 * 
 * <p>Fields are used to define what a Model is. They aren't instantiated directly - instead, when we create a class 
 * that extends {@link Ext.data.Model}, it will automatically create a Field instance for each field configured in a 
 * {@link Ext.data.Model Model}. For example, we might set up a model like this:</p>
 * 
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        'name', 'email',
        {name: 'age', type: 'int'},
        {name: 'gender', type: 'string', defaultValue: 'Unknown'}
    ]
});
</code></pre>
 * 
 * <p>Four fields will have been created for the User Model - name, email, age and gender. Note that we specified a
 * couple of different formats here; if we only pass in the string name of the field (as with name and email), the
 * field is set up with the 'auto' type. It's as if we'd done this instead:</p>
 * 
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'name', type: 'auto'},
        {name: 'email', type: 'auto'},
        {name: 'age', type: 'int'},
        {name: 'gender', type: 'string', defaultValue: 'Unknown'}
    ]
});
</code></pre>
 * 
 * <p><u>Types and conversion</u></p>
 * 
 * <p>The {@link #type} is important - it's used to automatically convert data passed to the field into the correct
 * format. In our example above, the name and email fields used the 'auto' type and will just accept anything that is
 * passed into them. The 'age' field had an 'int' type however, so if we passed 25.4 this would be rounded to 25.</p>
 * 
 * <p>Sometimes a simple type isn't enough, or we want to perform some processing when we load a Field's data. We can
 * do this using a {@link #convert} function. Here, we're going to create a new field based on another:</p>
 * 
<code><pre>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        'name', 'email',
        {name: 'age', type: 'int'},
        {name: 'gender', type: 'string', defaultValue: 'Unknown'},

        {
            name: 'firstName',
            convert: function(value, record) {
                var fullName  = record.get('name'),
                    splits    = fullName.split(" "),
                    firstName = splits[0];

                return firstName;
            }
        }
    ]
});
</code></pre>
 * 
 * <p>Now when we create a new User, the firstName is populated automatically based on the name:</p>
 * 
<code><pre>
var ed = Ext.ModelManager.create({name: 'Ed Spencer'}, 'User');

console.log(ed.get('firstName')); //logs 'Ed', based on our convert function
</code></pre>
 * 
 * <p>In fact, if we log out all of the data inside ed, we'll see this:</p>
 * 
<code><pre>
console.log(ed.data);

//outputs this:
{
    age: 0,
    email: "",
    firstName: "Ed",
    gender: "Unknown",
    name: "Ed Spencer"
}
</code></pre>
 * 
 * <p>The age field has been given a default of zero because we made it an int type. As an auto field, email has
 * defaulted to an empty string. When we registered the User model we set gender's {@link #defaultValue} to 'Unknown'
 * so we see that now. Let's correct that and satisfy ourselves that the types work as we expect:</p>
 * 
<code><pre>
ed.set('gender', 'Male');
ed.get('gender'); //returns 'Male'

ed.set('age', 25.4);
ed.get('age'); //returns 25 - we wanted an int, not a float, so no decimal places allowed
</code></pre>

 * 
 * <p><u>Loading Nested Data</u></p>
 * 
 * <p>Readers have the ability to automatically load deeply-nested data objects based on the {@link Ext.data.Association associations}
 * configured on each Model. Below is an example demonstrating the flexibility of these associations in a fictional CRM system which
 * manages a User, their Orders, OrderItems and Products. First we'll define the models:
 * 
<pre><code>
Ext.define("User", {
    extend: 'Ext.data.Model',
    fields: [
        'id', 'name'
    ],

    hasMany: {model: 'Order', name: 'orders'},

    proxy: {
        type: 'rest',
        url : 'users.json',
        reader: {
            type: 'json',
            root: 'users'
        }
    }
});

Ext.define("Order", {
    extend: 'Ext.data.Model',
    fields: [
        'id', 'total'
    ],

    hasMany  : {model: 'OrderItem', name: 'orderItems', associationKey: 'order_items'},
    belongsTo: 'User'
});

Ext.define("OrderItem", {
    extend: 'Ext.data.Model',
    fields: [
        'id', 'price', 'quantity', 'order_id', 'product_id'
    ],

    belongsTo: ['Order', {model: 'Product', associationKey: 'product'}]
});

Ext.define("Product", {
    extend: 'Ext.data.Model',
    fields: [
        'id', 'name'
    ],

    hasMany: 'OrderItem'
});
</code></pre>
 * 
 * <p>This may be a lot to take in - basically a User has many Orders, each of which is composed of several OrderItems. Finally,
 * each OrderItem has a single Product. This allows us to consume data like this:</p>
 * 
<pre><code>
{
    "users": [
        {
            "id": 123,
            "name": "Ed",
            "orders": [
                {
                    "id": 50,
                    "total": 100,
                    "order_items": [
                        {
                            "id"      : 20,
                            "price"   : 40,
                            "quantity": 2,
                            "product" : {
                                "id": 1000,
                                "name": "MacBook Pro"
                            }
                        },
                        {
                            "id"      : 21,
                            "price"   : 20,
                            "quantity": 3,

                }
            ]
        }
    ]
}
</code></pre>
 * 
 * <p>The JSON response is deeply nested - it returns all Users (in this case just 1 for simplicity's sake), all of the Orders
 * for each User (again just 1 in this case), all of the OrderItems for each Order (2 order items in this case), and finally
 * the Product associated with each OrderItem. Now we can read the data and use it as follows:
 * 
<pre><code>
var store = new Ext.data.Store({
    model: "User"
});

store.load({
    callback: function() {
        //the user that was loaded
        var user = store.first();

/**
 * @author Ed Spencer
 * @class Ext.data.reader.Json
 * @extends Ext.data.reader.Reader
 * 
 * <p>The JSON Reader is used by a Proxy to read a server response that is sent back in JSON format. This usually
 * happens as a result of loading a Store - for example we might create something like this:</p>
 * 
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email']
});

var store = new Ext.data.Store({
    model: 'User',
    proxy: {
        type: 'ajax',
        url : 'users.json',
        reader: {
            type: 'json'
        }
    }
});
</code></pre>
 * 
 * <p>The example above creates a 'User' model. Models are explained in the {@link Ext.data.Model Model} docs if you're
 * not already familiar with them.</p>
 * 
 * <p>We created the simplest type of JSON Reader possible by simply telling our {@link Ext.data.Store Store}'s 
 * {@link Ext.data.proxy.Proxy Proxy} that we want a JSON Reader. The Store automatically passes the configured model to the
 * Store, so it is as if we passed this instead:
 * 
<pre><code>
reader: {
    type : 'json',
    model: 'User'
}
</code></pre>
 * 
 * <p>The reader we set up is ready to read data from our server - at the moment it will accept a response like this:</p>
 * 
<pre><code>
[
    {
        "id": 1,
        "name": "Ed Spencer",
        "email": "ed@sencha.com"
    },
    {
        "id": 2,
        "name": "Abe Elias",
        "email": "abe@sencha.com"
    }
]
</code></pre>
 * 
 * <p><u>Reading other JSON formats</u></p>
 * 
 * <p>If you already have your JSON format defined and it doesn't look quite like what we have above, you can usually
 * pass JsonReader a couple of configuration options to make it parse your format. For example, we can use the 
 * {@link #root} configuration to parse data that comes back like this:</p>
 * 
<pre><code>
{
    "users": [
       {
           "id": 1,
           "name": "Ed Spencer",
           "email": "ed@sencha.com"
       },
       {
           "id": 2,
           "name": "Abe Elias",
           "email": "abe@sencha.com"
       }
    ]
}
</code></pre>
 * 
 * <p>To parse this we just pass in a {@link #root} configuration that matches the 'users' above:</p>
 * 
<pre><code>
reader: {
    type: 'json',
    root: 'users'
}
</code></pre>
 * 
 * <p>Sometimes the JSON structure is even more complicated. Document databases like CouchDB often provide metadata
 * around each record inside a nested structure like this:</p>
 * 
<pre><code>
{
    "total": 122,
    "offset": 0,
    "users": [
        {
            "id": "ed-spencer-1",
            "value": 1,
            "user": {
                "id": 1,
                "name": "Ed Spencer",
                "email": "ed@sencha.com"
            }
        }
    ]
}
</code></pre>
 * 
 * <p>In the case above the record data is nested an additional level inside the "users" array as each "user" item has
 * additional metadata surrounding it ('id' and 'value' in this case). To parse data out of each "user" item in the 
 * JSON above we need to specify the {@link #record} configuration like this:</p>
 * 
<pre><code>
reader: {
    type  : 'json',
    root  : 'users',
    record: 'user'
}
</code></pre>
 * 
 * <p><u>Response metadata</u></p>
 * 
 * <p>The server can return additional data in its response, such as the {@link #totalProperty total number of records} 
 * and the {@link #successProperty success status of the response}. These are typically included in the JSON response
 * like this:</p>
 * 
<pre><code>
{
    "total": 100,
    "success": true,
    "users": [
        {
            "id": 1,
            "name": "Ed Spencer",
            "email": "ed@sencha.com"
        }
    ]
}
</code></pre>
 * 
 * <p>If these properties are present in the JSON response they can be parsed out by the JsonReader and used by the
 * Store that loaded it. We can set up the names of these properties by specifying a final pair of configuration 
 * options:</p>
 * 
<pre><code>
reader: {
    type : 'json',
    root : 'users',
    totalProperty  : 'total',
    successProperty: 'success'
}
</code></pre>
 * 
 * <p>These final options are not necessary to make the Reader work, but can be useful when the server needs to report
 * an error or if it needs to indicate that there is a lot of data available of which only a subset is currently being
 * returned.</p>

 * @class Ext.data.proxy.Proxy
 * 
 * <p>Proxies are used by {@link Ext.data.Store Stores} to handle the loading and saving of {@link Ext.data.Model Model} data.
 * Usually developers will not need to create or interact with proxies directly.</p>
 * <p><u>Types of Proxy</u></p>
 * 
 * <p>There are two main types of Proxy - {@link Ext.data.proxy.Client Client} and {@link Ext.data.proxy.Server Server}. The Client proxies
 * save their data locally and include the following subclasses:</p>
 * 
 * <ul style="list-style-type: disc; padding-left: 25px">
 * <li>{@link Ext.data.proxy.LocalStorage LocalStorageProxy} - saves its data to localStorage if the browser supports it</li>
 * <li>{@link Ext.data.proxy.SessionStorage SessionStorageProxy} - saves its data to sessionStorage if the browsers supports it</li>
 * <li>{@link Ext.data.proxy.Memory MemoryProxy} - holds data in memory only, any data is lost when the page is refreshed</li>
 * </ul>
 * 
 * <p>The Server proxies save their data by sending requests to some remote server. These proxies include:</p>
 * 
 * <ul style="list-style-type: disc; padding-left: 25px">
 * <li>{@link Ext.data.proxy.Ajax Ajax} - sends requests to a server on the same domain</li>
 * <li>{@link Ext.data.proxy.JsonP JsonP} - uses JSON-P to send requests to a server on a different domain</li>
 * <li>{@link Ext.data.proxy.Direct Direct} - uses {@link Ext.direct} to send requests</li>
 * </ul>
 * 
 * <p>Proxies operate on the principle that all operations performed are either Create, Read, Update or Delete. These four operations 
 * are mapped to the methods {@link #create}, {@link #read}, {@link #update} and {@link #destroy} respectively. Each Proxy subclass 
 * implements these functions.</p>
 * 
 * <p>The CRUD methods each expect an {@link Ext.data.Operation Operation} object as the sole argument. The Operation encapsulates 
 * information about the action the Store wishes to perform, the {@link Ext.data.Model model} instances that are to be modified, etc.
 * See the {@link Ext.data.Operation Operation} documentation for more details. Each CRUD method also accepts a callback function to be 
 * called asynchronously on completion.</p>
 * 
 * <p>Proxies also support batching of Operations via a {@link Ext.data.Batch batch} object, invoked by the {@link #batch} method.</p>
 * 
 * @constructor
 * Creates the Proxy
 * @param {Object} config Optional config object

 * @author Ed Spencer
 * @class Ext.data.proxy.Ajax
 * @extends Ext.data.proxy.Server
 * 
 * <p>AjaxProxy is one of the most widely-used ways of getting data into your application. It uses AJAX requests to 
 * load data from the server, usually to be placed into a {@link Ext.data.Store Store}. Let's take a look at a typical
 * setup. Here we're going to set up a Store that has an AjaxProxy. To prepare, we'll also set up a 
 * {@link Ext.data.Model Model}:</p>
 * 
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email']
});

//The Store contains the AjaxProxy as an inline configuration
var store = new Ext.data.Store({
    model: 'User',
    proxy: {
        type: 'ajax',
        url : 'users.json'
    }
});

store.load();
</code></pre>
 * 
 * <p>Our example is going to load user data into a Store, so we start off by defining a {@link Ext.data.Model Model}
 * with the fields that we expect the server to return. Next we set up the Store itself, along with a {@link #proxy}
 * configuration. This configuration was automatically turned into an Ext.data.proxy.Ajax instance, with the url we
 * specified being passed into AjaxProxy's constructor. It's as if we'd done this:</p>
 * 
<pre><code>
new Ext.data.proxy.Ajax({
    url: 'users.json',
    model: 'User',
    reader: 'json'
});
</code></pre>
 * 
 * <p>A couple of extra configurations appeared here - {@link #model} and {@link #reader}. These are set by default 
 * when we create the proxy via the Store - the Store already knows about the Model, and Proxy's default 
 * {@link Ext.data.reader.Reader Reader} is {@link Ext.data.reader.Json JsonReader}.</p>
 * 
 * <p>Now when we call store.load(), the AjaxProxy springs into action, making a request to the url we configured
 * ('users.json' in this case). As we're performing a read, it sends a GET request to that url (see {@link #actionMethods}
 * to customize this - by default any kind of read will be sent as a GET request and any kind of write will be sent as a
 * POST request).</p>
 * 
 * <p><u>Limitations</u></p>
 * 
 * <p>AjaxProxy cannot be used to retrieve data from other domains. If your application is running on http://domainA.com
 * it cannot load data from http://domainB.com because browsers have a built-in security policy that prohibits domains
 * talking to each other via AJAX.</p>
 * 
 * <p>If you need to read data from another domain and can't set up a proxy server (some software that runs on your own
 * domain's web server and transparently forwards requests to http://domainB.com, making it look like they actually came
 * from http://domainA.com), you can use {@link Ext.data.proxy.JsonP} and a technique known as JSON-P (JSON with 
 * Padding), which can help you get around the problem so long as the server on http://domainB.com is set up to support
 * JSON-P responses. See {@link Ext.data.proxy.JsonP JsonPProxy}'s introduction docs for more details.</p>
 * 
 * <p><u>Readers and Writers</u></p>
 * 
 * <p>AjaxProxy can be configured to use any type of {@link Ext.data.reader.Reader Reader} to decode the server's response. If
 * no Reader is supplied, AjaxProxy will default to using a {@link Ext.data.reader.Json JsonReader}. Reader configuration
 * can be passed in as a simple object, which the Proxy automatically turns into a {@link Ext.data.reader.Reader Reader}
 * instance:</p>
 * 
<pre><code>
var proxy = new Ext.data.proxy.Ajax({
    model: 'User',
    reader: {
        type: 'xml',
        root: 'users'
    }
});

proxy.getReader(); //returns an {@link Ext.data.reader.Xml XmlReader} instance based on the config we supplied
</code></pre>
 * 
 * <p><u>Url generation</u></p>
 * 
 * <p>AjaxProxy automatically inserts any sorting, filtering, paging and grouping options into the url it generates for
 * each request. These are controlled with the following configuration options:</p>
 * 
 * <ul style="list-style-type: disc; padding-left: 20px;">
 *     <li>{@link #pageParam} - controls how the page number is sent to the server 
 *     (see also {@link #startParam} and {@link #limitParam})</li>
 *     <li>{@link #sortParam} - controls how sort information is sent to the server</li>
 *     <li>{@link #groupParam} - controls how grouping information is sent to the server</li>
 *     <li>{@link #filterParam} - controls how filter information is sent to the server</li>
 * </ul>
 * 
 * <p>Each request sent by AjaxProxy is described by an {@link Ext.data.Operation Operation}. To see how we can 
 * customize the generated urls, let's say we're loading the Proxy with the following Operation:</p>
 * 
<pre><code>
var operation = new Ext.data.Operation({
    action: 'read',
    page  : 2
});
</code></pre>
 * 
 * <p>Now we'll issue the request for this Operation by calling {@link #read}:</p>
 * 
<pre><code>
var proxy = new Ext.data.proxy.Ajax({
    url: '/users'
});

proxy.read(operation); //GET /users?page=2
</code></pre>
 * 
 * <p>Easy enough - the Proxy just copied the page property from the Operation. We can customize how this page data is
 * sent to the server:</p>
 * 
<pre><code>
var proxy = new Ext.data.proxy.Ajax({
    url: '/users',
    pagePage: 'pageNumber'
});

proxy.read(operation); //GET /users?pageNumber=2
</code></pre>
 * 
 * <p>Alternatively, our Operation could have been configured to send start and limit parameters instead of page:</p>
 * 
<pre><code>
var operation = new Ext.data.Operation({
    action: 'read',
    start : 50,
    limit : 25
});

var proxy = new Ext.data.proxy.Ajax({
    url: '/users'
});

proxy.read(operation); //GET /users?start=50&limit=25
</code></pre>
 * 
 * <p>Again we can customize this url:</p>
 * 
<pre><code>
var proxy = new Ext.data.proxy.Ajax({
    url: '/users',
    startParam: 'startIndex',
    limitParam: 'limitIndex'
});

proxy.read(operation); //GET /users?startIndex=50&limitIndex=25
</code></pre>
 * 
 * <p>AjaxProxy will also send sort and filter information to the server. Let's take a look at how this looks with a
 * more expressive Operation object:</p>
 * 
<pre><code>
var operation = new Ext.data.Operation({
    action: 'read',
    sorters: [
        new Ext.util.Sorter({
            property : 'name',
            direction: 'ASC'
        }),
        new Ext.util.Sorter({
            property : 'age',
            direction: 'DESC'
        })
    ],
    filters: [
        new Ext.util.Filter({
            property: 'eyeColor',
            value   : 'brown'
        })
    ]
});
</code></pre>
 * 
 * <p>This is the type of object that is generated internally when loading a {@link Ext.data.Store Store} with sorters
 * and filters defined. By default the AjaxProxy will JSON encode the sorters and filters, resulting in something like
 * this (note that the url is escaped before sending the request, but is left unescaped here for clarity):</p>
 * 
<pre><code>
var proxy = new Ext.data.proxy.Ajax({
    url: '/users'
});

proxy.read(operation); //GET /users?sort=[{"property":"name","direction":"ASC"},{"property":"age","direction":"DESC"}]&filter=[{"property":"eyeColor","value":"brown"}]
</code></pre>
 * 
 * <p>We can again customize how this is created by supplying a few configuration options. Let's say our server is set 
 * up to receive sorting information is a format like "sortBy=name#ASC,age#DESC". We can configure AjaxProxy to provide
 * that format like this:</p>
 * 
 <pre><code>
 var proxy = new Ext.data.proxy.Ajax({
     url: '/users',
     sortParam: 'sortBy',
     filterParam: 'filterBy',

     //our custom implementation of sorter encoding - turns our sorters into "name#ASC,age#DESC"
     encodeSorters: function(sorters) {
         var length   = sorters.length,
             sortStrs = [],
             sorter, i;

         for (i = 0; i < length; i++) {
             sorter = sorters[i];

             sortStrs[i] = sorter.property + '#' + sorter.direction
         }

         return sortStrs.join(",");
     }
 });

 proxy.read(operation); //GET /users?sortBy=name#ASC,age#DESC&filterBy=[{"property":"eyeColor","value":"brown"}]
 </code></pre>
 * 
 * <p>We can also provide a custom {@link #encodeFilters} function to encode our filters.</p>
 * 
 * @constructor
 * 
 * <p>Note that if this HttpProxy is being used by a {@link Ext.data.Store Store}, then the
 * Store's call to {@link #load} will override any specified <tt>callback</tt> and <tt>params</tt>
 * options. In this case, use the Store's {@link Ext.data.Store#events events} to modify parameters,
 * or react to loading events. The Store's {@link Ext.data.Store#baseParams baseParams} may also be
 * used to pass parameters known at instantiation time.</p>
 * 
 * <p>If an options parameter is passed, the singleton {@link Ext.Ajax} object will be used to make
 * the request.</p>

/**
 * @author Ed Spencer
 * @class Ext.data.Model
 *
 * <p>A Model represents some object that your application manages. For example, one might define a Model for Users, Products,
 * Cars, or any other real-world object that we want to model in the system. Models are registered via the {@link Ext.ModelManager model manager},
 * and are used by {@link Ext.data.Store stores}, which are in turn used by many of the data-bound components in Ext.</p>
 *
 * <p>Models are defined as a set of fields and any arbitrary methods and properties relevant to the model. For example:</p>
 *
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'name',  type: 'string'},
        {name: 'age',   type: 'int'},
        {name: 'phone', type: 'string'},
        {name: 'alive', type: 'boolean', defaultValue: true}
    ],

    changeName: function() {
        var oldName = this.get('name'),
            newName = oldName + " The Barbarian";

        this.set('name', newName);
    }
});
</code></pre>
*
* <p>The fields array is turned into a {@link Ext.util.MixedCollection MixedCollection} automatically by the {@link Ext.ModelManager ModelManager}, and all
* other functions and properties are copied to the new Model's prototype.</p>
*
* <p>Now we can create instances of our User model and call any model logic we defined:</p>
*
<pre><code>
var user = Ext.ModelManager.create({
    name : 'Conan',
    age  : 24,
    phone: '555-555-5555'
}, 'User');

user.changeName();
user.get('name'); //returns "Conan The Barbarian"
</code></pre>
 *
 * <p><u>Validations</u></p>
 *
 * <p>Models have built-in support for validations, which are executed against the validator functions in
 * {@link Ext.data.validations} ({@link Ext.data.validations see all validation functions}). Validations are easy to add to models:</p>
 *
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'name',     type: 'string'},
        {name: 'age',      type: 'int'},
        {name: 'phone',    type: 'string'},
        {name: 'gender',   type: 'string'},
        {name: 'username', type: 'string'},
        {name: 'alive',    type: 'boolean', defaultValue: true}
    ],

    validations: [
        {type: 'presence',  field: 'age'},
        {type: 'length',    field: 'name',     min: 2},
        {type: 'inclusion', field: 'gender',   list: ['Male', 'Female']},
        {type: 'exclusion', field: 'username', list: ['Admin', 'Operator']},
        {type: 'format',    field: 'username', matcher: /([a-z]+)[0-9]{2,3}/}
    ]
});
</code></pre>
 *
 * <p>The validations can be run by simply calling the {@link #validate} function, which returns a {@link Ext.data.Errors}
 * object:</p>
 *
<pre><code>
var instance = Ext.ModelManager.create({
    name: 'Ed',
    gender: 'Male',
    username: 'edspencer'
}, 'User');

var errors = instance.validate();
</code></pre>
 *
 * <p><u>Associations</u></p>
 *
 * <p>Models can have associations with other Models via {@link Ext.data.BelongsToAssociation belongsTo} and
 * {@link Ext.data.HasManyAssociation hasMany} associations. For example, let's say we're writing a blog administration
 * application which deals with Users, Posts and Comments. We can express the relationships between these models like this:</p>
 *
<pre><code>
Ext.define('Post', {
    extend: 'Ext.data.Model',
    fields: ['id', 'user_id'],

    belongsTo: 'User',
    hasMany  : {model: 'Comment', name: 'comments'}
});

Ext.define('Comment', {
    extend: 'Ext.data.Model',
    fields: ['id', 'user_id', 'post_id'],

    belongsTo: 'Post'
});

Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id'],

    hasMany: [
        'Post',
        {model: 'Comment', name: 'comments'}
    ]
});
</code></pre>
 *
 * <p>See the docs for {@link Ext.data.BelongsToAssociation} and {@link Ext.data.HasManyAssociation} for details on the usage
 * and configuration of associations. Note that associations can also be specified like this:</p>
 *
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id'],

    associations: [
        {type: 'hasMany', model: 'Post',    name: 'posts'},
        {type: 'hasMany', model: 'Comment', name: 'comments'}
    ]
});
</code></pre>
 *
 * <p><u>Using a Proxy</u></p>
 *
 * <p>Models are great for representing types of data and relationships, but sooner or later we're going to want to
 * load or save that data somewhere. All loading and saving of data is handled via a {@link Ext.data.proxy.Proxy Proxy},
 * which can be set directly on the Model:</p>
 *
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email'],

    proxy: {
        type: 'rest',
        url : '/users'
    }
});
</code></pre>
 *
 * <p>Here we've set up a {@link Ext.data.proxy.Rest Rest Proxy}, which knows how to load and save data to and from a
 * RESTful backend. Let's see how this works:</p>
 *
<pre><code>
var user = Ext.ModelManager.create({name: 'Ed Spencer', email: 'ed@sencha.com'}, 'User');

user.save(); //POST /users
</code></pre>
 *
 * <p>Calling {@link #save} on the new Model instance tells the configured RestProxy that we wish to persist this
 * Model's data onto our server. RestProxy figures out that this Model hasn't been saved before because it doesn't
 * have an id, and performs the appropriate action - in this case issuing a POST request to the url we configured
 * (/users). We configure any Proxy on any Model and always follow this API - see {@link Ext.data.proxy.Proxy} for a full
 * list.</p>
 *
 * <p>Loading data via the Proxy is equally easy:</p>
 *
<pre><code>
//get a reference to the User model class
var User = Ext.ModelManager.getModel('User');

//Uses the configured RestProxy to make a GET request to /users/123
User.load(123, {
    success: function(user) {
        console.log(user.getId()); //logs 123
    }
});
</code></pre>
 *
 * <p>Models can also be updated and destroyed easily:</p>
 *
<pre><code>
//the user Model we loaded in the last snippet:
user.set('name', 'Edward Spencer');

//tells the Proxy to save the Model. In this case it will perform a PUT request to /users/123 as this Model already has an id
user.save({
    success: function() {
        console.log('The User was updated');
    }
});

//tells the Proxy to destroy the Model. Performs a DELETE request to /users/123
user.destroy({
    success: function() {
        console.log('The User was destroyed!');
    }
});
</code></pre>
 *
 * <p><u>Usage in Stores</u></p>
 *
 * <p>It is very common to want to load a set of Model instances to be displayed and manipulated in the UI. We do this
 * by creating a {@link Ext.data.Store Store}:</p>
 *
<pre><code>
var store = new Ext.data.Store({
    model: 'User'
});

//uses the Proxy we set up on Model to load the Store data
store.load();
</code></pre>
 *
 * <p>A Store is just a collection of Model instances - usually loaded from a server somewhere. Store can also maintain
 * a set of added, updated and removed Model instances to be synchronized with the server via the Proxy. See the
 * {@link Ext.data.Store Store docs} for more information on Stores.</p>
 *
 * @constructor
 * @param {Object} data An object containing keys corresponding to this model's fields, and their associated values
 * @param {Number} id Optional unique ID to assign to this model instance

 * <p>The Component base class has built-in support for basic hide/show and enable/disable and size control behavior.</p>

 * It should not usually be necessary to instantiate a Component because there are provided subclasses which implement specialized Component
 * use cases which over most application needs. However it is possible to instantiate a base Component, and it will be renderable,
 * or will particpate in layouts as the child item of a Container:
{@img Ext.Component/Ext.Component.png Ext.Component component}
<pre><code>

        html: 'Hello world!',

        },
        renderTo: Ext.getBody()
    });
</code></pre>
 *</p>
 *<p>The Component above creates its encapsulating <code>div</code> upon render, and use the configured HTML as content. More complex
 * internal structure may be created using the {@link #renderTpl} configuration, although to display database-derived mass
 * data, it is recommended that an ExtJS data-backed Component such as a {Ext.view.DataView DataView}, or {Ext.grid.Panel GridPanel},
 * or {@link Ext.tree.Panel TreePanel} be used.</p>
 * @constructor
 * @param {Ext.core.Element/String/Object} config The configuration options may be specified as either:

     * <p>A floating Component may be used as a child item of a Container. This just allows the floating Component to seek a ZIndexManager by
     * examining the ownerCt chain.</p>
     * <p>When configured as floating, Components acquire, at render time, a {@link Ext.ZIndexManager ZIndexManager} which manages a stack
     * of related floating Components. The ZIndexManager brings a single floating Component to the top of its stack when
     * the Component's {@link #toFront} method is called.</p>
     * <p>The ZIndexManager is found by traversing up the {@link #ownerCt} chain to find an ancestor which itself is floating. This is so that
     * descendant floating Components of floating <i>Containers</i> (Such as a ComboBox dropdown within a Window) can have its zIndex managed relative
     * to any siblings, but always <b>above</b> that floating ancestor Container.</p>
     * <p>If no floating ancestor is found, a floating Component registers itself with the default {@link Ext.WindowManager ZIndexManager}.</p>
     * <p>Floating components <i>do not participate in the Container's layout</i>. Because of this, they are not rendered until you explicitly

Adds {@link Ext.Component Component}(s) to this Container.

##Description:##

- Fires the {@link #beforeadd} event before adding.
- The Container's {@link #defaults default config values} will be applied
  accordingly (see `{@link #defaults}` for details).
- Fires the `{@link #add}` event after the component has been added.

##Notes:##

If the Container is __already rendered__ when `add`
is called, it will render the newly added Component into its content area.

__**If**__ the Container was configured with a size-managing {@link #layout} manager, the Container
will recalculate its internal layout at this time too.

Note that the default layout manager simply renders child Components sequentially into the content area and thereafter performs no sizing.

If adding multiple new child Components, pass them as an array to the `add` method, so that only one layout recalculation is performed.

    tb = new {@link Ext.toolbar.Toolbar}({
        renderTo: document.body
    });  // toolbar is rendered
    tb.add([{text:'Button 1'}, {text:'Button 2'}]); // add multiple items. ({@link #defaultType} for {@link Ext.toolbar.Toolbar Toolbar} is 'button')

##Warning:## 

Components directly managed by the BorderLayout layout manager
may not be removed or added.  See the Notes for {@link Ext.layout.container.Border BorderLayout}
for more details.

/**
 * @class Ext.container.Container
 * @extends Ext.container.AbstractContainer
 * <p>Base class for any {@link Ext.Component} that may contain other Components. Containers handle the
 * basic behavior of containing items, namely adding, inserting and removing items.</p>
 *
 * <p>The most commonly used Container classes are {@link Ext.panel.Panel}, {@link Ext.window.Window} and {@link Ext.tab.Panel}.
 * If you do not need the capabilities offered by the aforementioned classes you can create a lightweight
 * Container to be encapsulated by an HTML element to your specifications by using the
 * <code><b>{@link Ext.Component#autoEl autoEl}</b></code> config option.</p>
 *
 * {@img Ext.Container/Ext.Container.png Ext.Container component} 
 * <p>The code below illustrates how to explicitly create a Container:<pre><code>
// explicitly create a Container
Ext.create('Ext.container.Container', {
    layout: {
        type: 'hbox'
    },
    width: 400,
    renderTo: Ext.getBody(),
    border: 1,
    style: {borderColor:'#000000', borderStyle:'solid', borderWidth:'1px'},
    defaults: {
        labelWidth: 80,
        // implicitly create Container by specifying xtype
        xtype: 'datefield',
        flex: 1,
        style: {
            padding: '10px'
        }
    },
    items: [{
        xtype: 'datefield',
        name: 'startDate',
        fieldLabel: 'Start date'
    },{
        xtype: 'datefield',
        name: 'endDate',
        fieldLabel: 'End date'
    }]
});
</code></pre></p>
 *
 * <p><u><b>Layout</b></u></p>
 * <p>Container classes delegate the rendering of child Components to a layout
 * manager class which must be configured into the Container using the
 * <code><b>{@link #layout}</b></code> configuration property.</p>
 * <p>When either specifying child <code>{@link #items}</code> of a Container,
 * or dynamically {@link #add adding} Components to a Container, remember to
 * consider how you wish the Container to arrange those child elements, and
 * whether those child elements need to be sized using one of Ext's built-in
 * <b><code>{@link #layout}</code></b> schemes. By default, Containers use the
 * {@link Ext.layout.container.Auto Auto} scheme which only
 * renders child components, appending them one after the other inside the
 * Container, and <b>does not apply any sizing</b> at all.</p>
 * <p>A common mistake is when a developer neglects to specify a
 * <b><code>{@link #layout}</code></b> (e.g. widgets like GridPanels or
 * TreePanels are added to Containers for which no <code><b>{@link #layout}</b></code>
 * has been specified). If a Container is left to use the default
 * {Ext.layout.container.Auto Auto} scheme, none of its
 * child components will be resized, or changed in any way when the Container
 * is resized.</p>
 * <p>Certain layout managers allow dynamic addition of child components.
 * Those that do include {@link Ext.layout.container.Card},
 * {@link Ext.layout.container.Anchor}, {@link Ext.layout.container.VBox}, {@link Ext.layout.container.HBox}, and
 * {@link Ext.layout.container.Table}. For example:<pre><code>
//  Create the GridPanel.
var myNewGrid = new Ext.grid.Panel({
    store: myStore,
    headers: myHeaders,
    title: 'Results', // the title becomes the title of the tab
});

myTabPanel.add(myNewGrid); // {@link Ext.tab.Panel} implicitly uses {@link Ext.layout.container.Card Card}
myTabPanel.{@link Ext.tab.Panel#setActiveTab setActiveTab}(myNewGrid);
 * </code></pre></p>
 * <p>The example above adds a newly created GridPanel to a TabPanel. Note that
 * a TabPanel uses {@link Ext.layout.container.Card} as its layout manager which
 * means all its child items are sized to {@link Ext.layout.container.Fit fit}
 * exactly into its client area.
 * <p><b><u>Overnesting is a common problem</u></b>.
 * An example of overnesting occurs when a GridPanel is added to a TabPanel
 * by wrapping the GridPanel <i>inside</i> a wrapping Panel (that has no
 * <code><b>{@link #layout}</b></code> specified) and then add that wrapping Panel
 * to the TabPanel. The point to realize is that a GridPanel <b>is</b> a
 * Component which can be added directly to a Container. If the wrapping Panel
 * has no <code><b>{@link #layout}</b></code> configuration, then the overnested
 * GridPanel will not be sized as expected.<p>
 *
 * <p><u><b>Adding via remote configuration</b></u></p>
 *
 * <p>A server side script can be used to add Components which are generated dynamically on the server.
 * An example of adding a GridPanel to a TabPanel where the GridPanel is generated by the server
 * based on certain parameters:
 * </p><pre><code>
// execute an Ajax request to invoke server side script:
Ext.Ajax.request({
    url: 'gen-invoice-grid.php',
    // send additional parameters to instruct server script
    params: {
        startDate: Ext.getCmp('start-date').getValue(),
        endDate: Ext.getCmp('end-date').getValue()
    },
    // process the response object to add it to the TabPanel:
    success: function(xhr) {
        var newComponent = eval(xhr.responseText); // see discussion below
        myTabPanel.add(newComponent); // add the component to the TabPanel
        myTabPanel.setActiveTab(newComponent);
    },
    failure: function() {
        Ext.Msg.alert("Grid create failed", "Server communication failure");
    }
});
</code></pre>
 * <p>The server script needs to return a JSON representation of a configuration object, which, when decoded
 * will return a config object with an {@link Ext.Component#xtype xtype}. The server might return the following
 * JSON:</p><pre><code>
{
    "xtype": 'grid',
    "title": 'Invoice Report',
    "store": {
        "model": 'Invoice',

            })

            "params": {
                "startDate": '01/01/2008',
                "endDate": '01/31/2008'
            }
        }
    },
    "headers": [
        {"header": "Customer", "width": 250, "dataIndex": 'customer', "sortable": true},
        {"header": "Invoice Number", "width": 120, "dataIndex": 'invNo', "sortable": true},

        {"header": "Value", "width": 120, "dataIndex": 'value', "renderer": 'usMoney', "sortable": true}
    ]
}
</code></pre>
 * <p>When the above code fragment is passed through the <code>eval</code> function in the success handler
 * of the Ajax request, the result will be a config object which, when added to a Container, will cause instantiation
 * of a GridPanel. <b>Be sure that the Container is configured with a layout which sizes and positions the child items to your requirements.</b></p>
 * <p>Note: since the code above is <i>generated</i> by a server script, the <code>autoLoad</code> params for

/**
 * @class Ext.button.Button
 * @extends Ext.Component

Create simple buttons with this component. Customisations include {@link #config-iconAlign aligned}
{@link #config-iconCls icons}, {@link #config-menu dropdown menus}, {@link #config-tooltip tooltips}
and {@link #config-scale sizing options}. Specify a {@link #config-handler handler} to run code when
a user clicks the button, or use {@link #config-listeners listeners} for other events such as
{@link #events-mouseover mouseover}.

{@img Ext.button.Button/Ext.button.Button1.png Ext.button.Button component}
Example usage:

    Ext.create('Ext.Button', {
        text: 'Click me',
        renderTo: Ext.getBody(),        
        handler: function() {
            alert('You clicked the button!')
        }
    });

The {@link #handler} configuration can also be updated dynamically using the {@link #setHandler} method.
Example usage:

    Ext.create('Ext.Button', {
        text    : 'Dyanmic Handler Button',
        renderTo: Ext.getBody(),
        handler : function() {
            //this button will spit out a different number every time you click it.
            //so firstly we must check if that number is already set:
            if (this.clickCount) {
                //looks like the property is already set, so lets just add 1 to that number and alert the user
                this.clickCount++;
                alert('You have clicked the button "' + this.clickCount + '" times.\n\nTry clicking it again..');
            } else {
                //if the clickCount property is not set, we will set it and alert the user
                this.clickCount = 1;
                alert('You just clicked the button for the first time!\n\nTry pressing it again..');
            }
        }
    });

A button within a container:

    Ext.create('Ext.Container', {
        renderTo: Ext.getBody(),
        items   : [
            {
                xtype: 'button',
                text : 'My Button'
            }
        ]
    });

A useful option of Button is the {@link #scale} configuration. This configuration has three different options:
* `'small'`
* `'medium'`
* `'large'`

{@img Ext.button.Button/Ext.button.Button2.png Ext.button.Button component}
Example usage:

    Ext.create('Ext.Button', {
        renderTo: document.body,
        text    : 'Click me',
        scale   : 'large'
    });

Buttons can also be toggled. To enable this, you simple set the {@link #enableToggle} property to `true`.
{@img Ext.button.Button/Ext.button.Button3.png Ext.button.Button component}
Example usage:

    Ext.create('Ext.Button', {
        renderTo: Ext.getBody(),
        text: 'Click Me',
        enableToggle: true
    });

You can assign a menu to a button by using the {@link #menu} configuration. This standard configuration can either be a reference to a {@link Ext.menu.Menu menu}
object, a {@link Ext.menu.Menu menu} id or a {@link Ext.menu.Menu menu} config blob. When assigning a menu to a button, an arrow is automatically added to the button.
You can change the alignment of the arrow using the {@link #arrowAlign} configuration on button.
{@img Ext.button.Button/Ext.button.Button4.png Ext.button.Button component}
Example usage:

    Ext.create('Ext.Button', {
        text      : 'Menu button',
        renderTo  : Ext.getBody(),        
        arrowAlign: 'bottom',
        menu      : [
            {text: 'Item 1'},
            {text: 'Item 2'},
            {text: 'Item 3'},
            {text: 'Item 4'}
        ]
    });

Using listeners, you can easily listen to events fired by any component, using the {@link #listeners} configuration or using the {@link #addListener} method.
Button has a variety of different listeners:
* `click`
* `toggle`
* `mouseover`
* `mouseout`
* `mouseshow`
* `menuhide`
* `menutriggerover`
* `menutriggerout`

Example usage:

    Ext.create('Ext.Button', {
        text     : 'Button',
        renderTo : Ext.getBody(),
        listeners: {
            click: function() {
                //this == the button, as we are in the local scope
                this.setText('I was clicked!');
            },
            mouseover: function() {
                //set a new config which says we moused over, if not already set
                if (!this.mousedOver) {
                    this.mousedOver = true;
                    alert('You moused over a button!\n\nI wont do this again.');
                }
            }
        }
    });

/**
 * @class Ext.FocusManager

The FocusManager is responsible for globally:

1. Managing component focus
2. Providing basic keyboard navigation
3. (optional) Provide a visual cue for focused components, in the form of a focus ring/frame.

To activate the FocusManager, simply call {@link #enable `Ext.FocusManager.enable();`}. In turn, you may
deactivate the FocusManager by subsequently calling {@link #disable `Ext.FocusManager.disable();`}.  The
FocusManager is disabled by default.

To enable the optional focus frame, pass `true` or `{focusFrame: true}` to {@link #enable}.

Another feature of the FocusManager is to provide basic keyboard focus navigation scoped to any {@link Ext.container.Container}
that would like to have navigation between its child {@link Ext.Component}'s. The {@link Ext.container.Container} can simply
call {@link #subscribe Ext.FocusManager.subscribe} to take advantage of this feature, and can at any time call
{@link #unsubscribe Ext.FocusManager.unsubscribe} to turn the navigation off.

/**
 * @class Ext.toolbar.Toolbar
 * @extends Ext.container.Container

Basic Toolbar class. Although the {@link Ext.container.Container#defaultType defaultType} for Toolbar is {@link Ext.button.Button button}, Toolbar 
elements (child items for the Toolbar container) may be virtually any type of Component. Toolbar elements can be created explicitly via their 
constructors, or implicitly via their xtypes, and can be {@link #add}ed dynamically.

__Some items have shortcut strings for creation:__

| Shortcut | xtype         | Class                         | Description                                        |
|:---------|:--------------|:------------------------------|:---------------------------------------------------|
| `->`     | `tbspacer`    | {@link Ext.toolbar.Fill}      | begin using the right-justified button container   |
| `-`      | `tbseparator` | {@link Ext.toolbar.Separator} | add a vertical separator bar between toolbar items |
| ` `      | `tbspacer`    | {@link Ext.toolbar.Spacer}    | add horiztonal space between elements              |

{@img Ext.toolbar.Toolbar/Ext.toolbar.Toolbar1.png Toolbar component}
Example usage:

    Ext.create('Ext.toolbar.Toolbar", {
        renderTo: document.body,
        width   : 500,
        items: [
            {
                // xtype: 'button', // default for Toolbars
                text: 'Button'
            },
            {
                xtype: 'splitbutton',
                text : 'Split Button'
            },
            // begin using the right-justified button container
            '->', // same as {xtype: 'tbfill'}, // Ext.toolbar.Fill
            {
                xtype    : 'textfield',
                name     : 'field1',
                emptyText: 'enter search term'
            },
            // add a vertical separator bar between toolbar items
            '-', // same as {xtype: 'tbseparator'} to create Ext.toolbar.Separator
            'text 1', // same as {xtype: 'tbtext', text: 'text1'} to create Ext.toolbar.TextItem
            {xtype: 'tbspacer'},// same as ' ' to create Ext.toolbar.Spacer
            'text 2',
            {xtype: 'tbspacer', width: 50}, // add a 50px space
            'text 3'
        ]
    });

Toolbars have {@link #enable} and {@link #disable} methods which when called, will enable/disable all items within your toolbar.

{@img Ext.toolbar.Toolbar/Ext.toolbar.Toolbar2.png Toolbar component}
Example usage:

    Ext.create('Ext.toolbar.Toolbar', {
        renderTo: document.body,
        width   : 400,
        items: [
            {
                text: 'Button'
            },
            {
                xtype: 'splitbutton',
                text : 'Split Button'
            },
            '->',
            {
                xtype    : 'textfield',
                name     : 'field1',
                emptyText: 'enter search term'
            }
        ]
    });

{@img Ext.toolbar.Toolbar/Ext.toolbar.Toolbar3.png Toolbar component}
Example usage:
    
    var enableBtn = Ext.create('Ext.button.Button', {
        text    : 'Enable All Items',
        disabled: true,
        scope   : this,
        handler : function() {
            //disable the enable button and enable the disable button
            enableBtn.disable();
            disableBtn.enable();
            
            //enable the toolbar
            toolbar.enable();
        }
    });
    
    var disableBtn = Ext.create('Ext.button.Button', {
        text    : 'Disable All Items',
        scope   : this,
        handler : function() {
            //enable the enable button and disable button
            disableBtn.disable();
            enableBtn.enable();
            
            //disable the toolbar
            toolbar.disable();
        }
    });
    
    var toolbar = Ext.create('Ext.toolbar.Toolbar', {
        renderTo: document.body,
        width   : 400,
        margin  : '5 0 0 0',
        items   : [enableBtn, disableBtn]
    });

Adding items to and removing items from a toolbar is as simple as calling the {@link #add} and {@link #remove} methods. There is also a {@link #removeAll} method 
which remove all items within the toolbar.

{@img Ext.toolbar.Toolbar/Ext.toolbar.Toolbar4.png Toolbar component}
Example usage:

    var toolbar = Ext.create('Ext.toolbar.Toolbar', {
        renderTo: document.body,

        items: [

    });

/**
 * @class Ext.fx.Animator
 * Animation instance

This class is used to run keyframe based animations, which follows the CSS3 based animation structure. 
Keyframe animations differ from typical from/to animations in that they offer the ability to specify values 
at various points throughout the animation.

__Using Keyframes__
The {@link #keyframes} option is the most important part of specifying an animation when using this 
class. A key frame is a point in a particular animation. We represent this as a percentage of the
total animation duration. At each key frame, we can specify the target values at that time. Note that
you *must* specify the values at 0% and 100%, the start and ending values. There is also a {@link keyframe}
event that fires after each key frame is reached.

__Example Usage__
In the example below, we modify the values of the element at each fifth throughout the animation.

    Ext.create('Ext.fx.Animator', {
        target: Ext.getBody().createChild({
            style: {
                width: '100px',
                height: '100px',
                'background-color': 'red'
            }
        }),
        duration: 10000, // 10 seconds
        keyframes: {
            0: {
                opacity: 1,
                backgroundColor: 'FF0000'
            },
            20: {
                x: 30,
                opacity: 0.5    
            },
            40: {
                x: 130,
                backgroundColor: '0000FF'    
            },
            60: {
                y: 80,
                opacity: 0.3    
            },
            80: {
                width: 200,
                y: 200    
            },
            100: {
                opacity: 1,
                backgroundColor: '00FF00'
            }

/**
 * @class Ext.fx.Easing
 * 
This class contains a series of function definitions used to modify values during an animation.
They describe how the intermediate values used during a transition will be calculated. It allows for a transition to change
speed over its duration. The following options are available: 

- linear The default easing type
- backIn
- backOut
- bounceIn
- bounceOut
- ease
- easeIn
- easeOut
- easeInOut
- elasticIn
- elasticOut
- cubic-bezier(x1, y1, x2, y2)

Note that cubic-bezier will create a custom easing curve following the CSS3 transition-timing-function specification `{@link http://www.w3.org/TR/css3-transitions/#transition-timing-function_tag}`. The four values specify points P1 and P2 of the curve
as (x1, y1, x2, y2). All values must be in the range [0, 1] or the definition is invalid.

/**
 * @class Ext.fx.Anim
 * 
 * This class manages animation for a specific {@link #target}. The animation allows
 * animation of various properties on the target, such as size, position, color and others.
 * 
 * ## Starting Conditions
 * The starting conditions for the animation are provided by the {@link #from} configuration.
 * Any/all of the properties in the {@link #from} configuration can be specified. If a particular
 * property is not defined, the starting value for that property will be read directly from the target.
 * 
 * ## End Conditions
 * The ending conditions for the animation are provided by the {@link #to} configuration. These mark
 * the final values once the animations has finished. The values in the {@link #from} can mirror
 * those in the {@link #to} configuration to provide a starting point.
 * 
 * ## Other Options
 *  - {@link #duration}: Specifies the time period of the animation.
 *  - {@link #easing}: Specifies the easing of the animation.
 *  - {@link #iterations}: Allows the animation to repeat a number of times.
 *  - {@link #alternate}: Used in conjunction with {@link #iterations}, reverses the direction every second iteration.
 * 
 * ## Example Code
 * 
 *     var myComponent = Ext.create('Ext.Component', {
 *         renderTo: document.body,
 *         width: 200,
 *         height: 200,
 *         style: 'border: 1px solid red;'
 *     });
 *     
 *     new Ext.fx.Anim({
 *         target: myComponent,
 *         duration: 1000,
 *         from: {
 *             width: 400 //starting width 400
 *         },
 *         to: {
 *             width: 300, //end width 300

/**
 * @class Ext.dd.DragDrop
 * Defines the interface and base operation of items that that can be
 * dragged or can be drop targets.  It was designed to be extended, overriding
 * the event handlers for startDrag, onDrag, onDragOver and onDragOut.
 * Up to three html elements can be associated with a DragDrop instance:
 * <ul>
 * <li>linked element: the element that is passed into the constructor.
 * This is the element which defines the boundaries for interaction with
 * other DragDrop objects.</li>
 * <li>handle element(s): The drag operation only occurs if the element that
 * was clicked matches a handle element.  By default this is the linked
 * element, but there are times that you will want only a portion of the
 * linked element to initiate the drag operation, and the setHandleElId()
 * method provides a way to define this.</li>
 * <li>drag element: this represents the element that would be moved along
 * with the cursor during a drag operation.  By default, this is the linked
 * element itself as in {@link Ext.dd.DD}.  setDragElId() lets you define
 * a separate element that would be moved, as in {@link Ext.dd.DDProxy}.
 * </li>
 * </ul>
 * This class should not be instantiated until the onload event to ensure that
 * the associated elements are available.
 * The following would define a DragDrop obj that would interact with any
 * other DragDrop obj in the "group1" group:
 * <pre>
 *  dd = new Ext.dd.DragDrop("div1", "group1");
 * </pre>
 * Since none of the event handlers have been implemented, nothing would
 * actually happen if you were to run the code above.  Normally you would
 * override this class or one of the default implementations, but you can
 * also override the methods you want on an instance of the class...
 * <pre>
 *  dd.onDragDrop = function(e, id) {
 *  &nbsp;&nbsp;alert("dd was dropped on " + id);
 *  }
 * </pre>
 * @constructor
 * @param {String} id of the element that is linked to this instance
 * @param {String} sGroup the group of related DragDrop objects
 * @param {object} config an object containing configurable attributes
 *                Valid properties for DragDrop:
 *                    padding, isTarget, maintainOffset, primaryButtonOnly

/**
 * @class Ext.panel.Panel
 * @extends Ext.panel.AbstractPanel
 * <p>Panel is a container that has specific functionality and structural components that make
 * it the perfect building block for application-oriented user interfaces.</p>
 * <p>Panels are, by virtue of their inheritance from {@link Ext.container.Container}, capable
 * of being configured with a {@link Ext.container.Container#layout layout}, and containing child Components.</p>
 * <p>When either specifying child {@link Ext.Component#items items} of a Panel, or dynamically {@link Ext.container.Container#add adding} Components
 * to a Panel, remember to consider how you wish the Panel to arrange those child elements, and whether
 * those child elements need to be sized using one of Ext&#39;s built-in <code><b>{@link Ext.container.Container#layout layout}</b></code> schemes. By
 * default, Panels use the {@link Ext.layout.container.Auto Auto} scheme. This simply renders
 * child components, appending them one after the other inside the Container, and <b>does not apply any sizing</b>
 * at all.</p>
 * {@img Ext.panel.Panel/panel.png Panel components}
 * <p>A Panel may also contain {@link #bbar bottom} and {@link #tbar top} toolbars, along with separate
 * {@link #header}, {@link #footer} and {@link #body} sections (see {@link #frame} for additional
 * information).</p>
 * <p>Panel also provides built-in {@link #collapsible collapsible, expandable} and {@link #closable} behavior.
 * Panels can be easily dropped into any {@link Ext.container.Container Container} or layout, and the
 * layout and rendering pipeline is {@link Ext.container.Container#add completely managed by the framework}.</p>
 * <p><b>Note:</b> By default, the <code>{@link #closable close}</code> header tool <i>destroys</i> the Panel resulting in removal of the Panel
 * and the destruction of any descendant Components. This makes the Panel object, and all its descendants <b>unusable</b>. To enable the close
 * tool to simply <i>hide</i> a Panel for later re-use, configure the Panel with <b><code>{@link #closeAction closeAction: 'hide'}</code></b>.</p>
 * <p>Usually, Panels are used as constituents within an application, in which case, they would be used as child items of Containers,
 * and would themselves use Ext.Components as child {@link #items}. However to illustrate simply rendering a Panel into the document,
 * here&#39;s how to do it:<pre><code>
Ext.create('Ext.panel.Panel', {
    title: 'Hello',
    width: 200,
    html: '&lt;p&gt;World!&lt;/p&gt;',
    renderTo: document.body
});
</code></pre></p>
 * <p>A more realistic scenario is a Panel created to house input fields which will not be rendered, but used as a constituent part of a Container:<pre><code>
var filterPanel = Ext.create('Ext.panel.Panel', {
    bodyPadding: 5,  // Don&#39;t want content to crunch against the borders
    title: 'Filters',
    items: [{
        xtype: 'datefield',
        fieldLabel: 'Start date'
    }, {
        xtype: 'datefield',
        fieldLabel: 'End date'
    }]
});
</code></pre></p>
 * <p>Note that the Panel above is not configured to render into the document, nor is it configured with a size or position. In a real world scenario,
 * the Container into which the Panel is added will use a {@link #layout} to render, size and position its child Components.</p>
 * <p>Panels will often use specific {@link #layout}s to provide an application with shape and structure by containing and arranging child
 * Components: <pre><code>
var resultsPanel = Ext.create('Ext.panel.Panel', {
    title: 'Results',
    width: 600,
    height: 400,
    renderTo: document.body,
    layout: {
        type: 'vbox',       // Arrange child items vertically
        align: 'stretch',    // Each takes up full width
        padding: 5
    },
    items: [{               // Results grid specified as a config object with an xtype of 'grid'
        xtype: 'grid',
        columns: [{header: 'Column One'}],            // One header just for show. There&#39;s no data,
        store: Ext.create('Ext.data.ArrayStore', {}), // A dummy empty data store
        flex: 1                                       // Use 1/3 of Container&#39;s height (hint to Box layout)
    }, {
        xtype: 'splitter'   // A splitter between the two child items
    }, {                    // Details Panel specified as a config object (no xtype defaults to 'panel').
        title: 'Details',
        bodyPadding: 5,
        items: [{
            fieldLabel: 'Data item',
            xtype: 'textfield'
        }], // An array of form fields
        flex: 2             // Use 2/3 of Container&#39;s height (hint to Box layout)
    }]
});
</code></pre>
 * The example illustrates one possible method of displaying search results. The Panel contains a grid with the resulting data arranged
 * in rows. Each selected row may be displayed in detail in the Panel below. The {@link Ext.layout.container.VBox vbox} layout is used
 * to arrange the two vertically. It is configured to stretch child items horizontally to full width. Child items may either be configured
 * with a numeric height, or with a <code>flex</code> value to distribute available space proportionately.</p>
 * <p>This Panel itself may be a child item of, for exaple, a {@link Ext.tab.Panel} which will size its child items to fit within its
 * content area.</p>
 * <p>Using these techniques, as long as the <b>layout</b> is chosen and configured correctly, an application may have any level of
 * nested containment, all dynamically sized according to configuration, the user&#39;s preference and available browser size.</p>

/**
 * @class Ext.tip.ToolTip
 * @extends Ext.tip.Tip
 * 
 * ToolTip is a {@link Ext.tip.Tip} implementation that handles the common case of displaying a
 * tooltip when hovering over a certain element or elements on the page. It allows fine-grained
 * control over the tooltip's alignment relative to the target element or mouse, and the timing
 * of when it is automatically shown and hidden.
 * 
 * This implementation does **not** have a built-in method of automatically populating the tooltip's
 * text based on the target element; you must either configure a fixed {@link #html} value for each
 * ToolTip instance, or implement custom logic (e.g. in a {@link #beforeshow} event listener) to
 * generate the appropriate tooltip content on the fly. See {@link Ext.tip.QuickTip} for a more
 * convenient way of automatically populating and configuring a tooltip based on specific DOM
 * attributes of each target element.
 * 
 * ## Basic Example
 * 
 *     var tip = Ext.create('Ext.tip.ToolTip', {
 *         target: 'clearButton',
 *         html: 'Press this button to clear the form'
 *     });
 * 
 * {@img Ext.tip.ToolTip/Ext.tip.ToolTip1.png Basic Ext.tip.ToolTip}
 * 
 * ## Delegation
 * 
 * In addition to attaching a ToolTip to a single element, you can also use delegation to attach
 * one ToolTip to many elements under a common parent. This is more efficient than creating many
 * ToolTip instances. To do this, point the {@link #target} config to a common ancestor of all the
 * elements, and then set the {@link #delegate} config to a CSS selector that will select all the
 * appropriate sub-elements.
 * 
 * When using delegation, it is likely that you will want to programmatically change the content
 * of the ToolTip based on each delegate element; you can do this by implementing a custom
 * listener for the {@link #beforeshow} event. Example:
 * 
 *     var myGrid = Ext.create('Ext.grid.GridPanel', gridConfig);
 *     myGrid.on('render', function(grid) {
 *         var view = grid.getView();    // Capture the grid's view.
 *         grid.tip = Ext.create('Ext.tip.ToolTip', {
 *             target: view.el,          // The overall target element.
 *             delegate: view.itemSelector, // Each grid row causes its own seperate show and hide.
 *             trackMouse: true,         // Moving within the row should not hide the tip.
 *             renderTo: Ext.getBody(),  // Render immediately so that tip.body can be referenced prior to the first show.
 *             listeners: {              // Change content dynamically depending on which element triggered the show.
 *                 beforeshow: function updateTipBody(tip) {
 *                     tip.update('Over company "' + view.getRecord(tip.triggerElement).get('company') + '"');
 *                 }
 *             }
 *         });
 *     });
 * 
 * {@img Ext.tip.ToolTip/Ext.tip.ToolTip2.png Ext.tip.ToolTip with delegation}
 * 
 * ## Alignment
 * 
 * The following configuration properties allow control over how the ToolTip is aligned relative to
 * the target element and/or mouse pointer:
 * 
 *  - {@link #anchor}
 *  - {@link #anchorToTarget}
 *  - {@link #anchorOffset}
 *  - {@link #trackMouse}
 *  - {@link #mouseOffset}
 * 
 * ## Showing/Hiding
 * 
 * The following configuration properties allow control over how and when the ToolTip is automatically
 * shown and hidden:
 * 
 *  - {@link #autoHide}
 *  - {@link #showDelay}
 *  - {@link #hideDelay}
 *  - {@link #dismissDelay}

/**
 * @class Ext.tip.QuickTipManager
 * <p>Provides attractive and customizable tooltips for any element. The QuickTips
 * singleton is used to configure and manage tooltips globally for multiple elements
 * in a generic manner.  To create individual tooltips with maximum customizability,
 * you should consider either {@link Ext.tip.Tip} or {@link Ext.tip.ToolTip}.</p>
 * <p>Quicktips can be configured via tag attributes directly in markup, or by
 * registering quick tips programmatically via the {@link #register} method.</p>
 * <p>The singleton's instance of {@link Ext.tip.QuickTip} is available via
 * {@link #getQuickTip}, and supports all the methods, and all the all the
 * configuration properties of Ext.tip.QuickTip. These settings will apply to all
 * tooltips shown by the singleton.</p>
 * <p>Below is the summary of the configuration properties which can be used.
 * For detailed descriptions see the config options for the {@link Ext.tip.QuickTip QuickTip} class</p>
 * <p><b>QuickTips singleton configs (all are optional)</b></p>
 * <div class="mdetail-params"><ul><li>dismissDelay</li>
 * <li>hideDelay</li>
 * <li>maxWidth</li>
 * <li>minWidth</li>
 * <li>showDelay</li>
 * <li>trackMouse</li></ul></div>
 * <p><b>Target element configs (optional unless otherwise noted)</b></p>
 * <div class="mdetail-params"><ul><li>autoHide</li>
 * <li>cls</li>
 * <li>dismissDelay (overrides singleton value)</li>
 * <li>target (required)</li>
 * <li>text (required)</li>
 * <li>title</li>
 * <li>width</li></ul></div>
 * <p>Here is an example showing how some of these config options could be used:</p>
 *
 * {@img Ext.tip.QuickTipManager/Ext.tip.QuickTipManager.png Ext.tip.QuickTipManager component}
 *
 * ## Code
 *    // Init the singleton.  Any tag-based quick tips will start working.
 *    Ext.tip.QuickTipManager.init();
 *    
 *    // Apply a set of config properties to the singleton
 *    Ext.apply(Ext.tip.QuickTipManager.getQuickTip(), {
 *        maxWidth: 200,
 *        minWidth: 100,
 *        showDelay: 50      // Show 50ms after entering target
 *    });
 *    
 *    // Create a small panel to add a quick tip to
 *    Ext.create('Ext.container.Container', {
 *        id: 'quickTipContainer',
 *        width: 200,
 *        height: 150,
 *        style: {
 *            backgroundColor:'#000000'
 *        },
 *        renderTo: Ext.getBody()
 *    });
 *
 *    
 *    // Manually register a quick tip for a specific element
 *    Ext.tip.QuickTipManager.register({
 *        target: 'quickTipContainer',
 *        title: 'My Tooltip',
 *        text: 'This tooltip was added in code',
 *        width: 100,
 *        dismissDelay: 10000 // Hide after 10 seconds hover
 *    });
</code></pre>
 * <p>To register a quick tip in markup, you simply add one or more of the valid QuickTip attributes prefixed with
 * the <b>ext:</b> namespace.  The HTML element itself is automatically set as the quick tip target. Here is the summary
 * of supported attributes (optional unless otherwise noted):</p>
 * <ul><li><b>hide</b>: Specifying "user" is equivalent to setting autoHide = false.  Any other value will be the
 * same as autoHide = true.</li>
 * <li><b>qclass</b>: A CSS class to be applied to the quick tip (equivalent to the 'cls' target element config).</li>
 * <li><b>qtip (required)</b>: The quick tip text (equivalent to the 'text' target element config).</li>
 * <li><b>qtitle</b>: The quick tip title (equivalent to the 'title' target element config).</li>
 * <li><b>qwidth</b>: The quick tip width (equivalent to the 'width' target element config).</li></ul>
 * <p>Here is an example of configuring an HTML element to display a tooltip from markup:</p>
 * <pre><code>
// Add a quick tip to an HTML button
&lt;input type="button" value="OK" ext:qtitle="OK Button" ext:qwidth="100"
     data-qtip="This is a quick tip from markup!">&lt;/input>

/**
 * @class Ext.app.Application
 * @constructor
 * 
 * Represents an Ext JS 4 application, which is typically a single page app using a {@link Ext.container.Viewport Viewport}.
 * A typical Ext.app.Application might look like this:
 * 
 * Ext.application({
     name: 'MyApp',
     launch: function() {
         Ext.create('Ext.container.Viewport', {
             items: {
                 html: 'My App'
             }
         });
     }
 });
 * 
 * This does several things. First it creates a global variable called 'MyApp' - all of your Application's classes (such
 * as its Models, Views and Controllers) will reside under this single namespace, which drastically lowers the chances
 * of colliding global variables.
 * 
 * When the page is ready and all of your JavaScript has loaded, your Application's {@link #launch} function is called,
 * at which time you can run the code that starts your app. Usually this consists of creating a Viewport, as we do in
 * the example above.
 * 
 * <u>Telling Application about the rest of the app</u>
 * 
 * Because an Ext.app.Application represents an entire app, we should tell it about the other parts of the app - namely
 * the Models, Views and Controllers that are bundled with the application. Let's say we have a blog management app; we
 * might have Models and Controllers for Posts and Comments, and Views for listing, adding and editing Posts and Comments.
 * Here's how we'd tell our Application about all these things:
 * 
 * Ext.application({
     name: 'Blog',
     models: ['Post', 'Comment'],
     controllers: ['Posts', 'Comments'],

     launch: function() {
         ...
     }
 });
 * 
 * Note that we didn't actually list the Views directly in the Application itself. This is because Views are managed by
 * Controllers, so it makes sense to keep those dependencies there. The Application will load each of the specified 
 * Controllers using the pathing conventions laid out in the <a href="../guide/application_architecture">application 
 * architecture guide</a> - in this case expecting the controllers to reside in app/controller/Posts.js and
 * app/controller/Comments.js. In turn, each Controller simply needs to list the Views it uses and they will be
 * automatically loaded. Here's how our Posts controller like be defined:
 * 
 * Ext.define('MyApp.controller.Posts', {
     extend: 'Ext.app.Controller',
     views: ['posts.List', 'posts.Edit'],

     //the rest of the Controller here
 });
 * 
 * Because we told our Application about our Models and Controllers, and our Controllers about their Views, Ext JS will
 * automatically load all of our app files for us. This means we don't have to manually add script tags into our html
 * files whenever we add a new class, but more importantly it enables us to create a minimized build of our entire 
 * application using the Ext JS 4 SDK Tools.
 * 
 * For more information about writing Ext JS 4 applications, please see the <a href="../guide/application_architecture">
 * application architecture guide</a>.

 * A composite Sprite handles a group of sprites with common methods to a sprite

 *
 * CompositeSprite extends {@link Ext.util.MixedCollection} so you can use the same methods
 * in `MixedCollection` to iterate through sprites, add and remove elements, etc.

 *         surface: drawComponent.surface
 *     });
 *                  
 * Then just by using `MixedCollection` methods it's possible to add {@link Ext.draw.Sprite}s:
 *  
 *     group.add(sprite1);
 *     group.add(sprite2);
 *     group.add(sprite3);
 *

 * @class Ext.chart.Mask
 *

 * A Mask can be used to select a certain region in a chart.
 * When enabled, the `select` event will be triggered when a
 * region is selected by the mask, allowing the user to perform
 * other tasks like zooming on that region, etc.
 *
 * In order to use the mask one has to set the Chart `mask` option to
 * `true`, `vertical` or `horizontal`. Then a possible configuration for the
 * listener could be:
 *

/**
 * @class Ext.draw.Surface
 * @extends Object
 *
 * A Surface is an interface to render methods inside a draw {@link Ext.draw.Component}.
 * A Surface contains methods to render sprites, get bounding boxes of sprites, add
 * sprites to the canvas, initialize other graphic components, etc. One of the most used
 * methods for this class is the `add` method, to add Sprites to the surface.
 *
 * Most of the Surface methods are abstract and they have a concrete implementation
 * in VML or SVG engines.
 *
 * A Surface instance can be accessed as a property of a draw component. For example:
 *
 *     drawComponent.surface.add({
 *         type: 'circle',
 *         fill: '#ffc',
 *         radius: 100,
 *         x: 100,
 *         y: 100
 *     });
 *
 * The configuration object passed in the `add` method is the same as described in the {@link Ext.draw.Sprite}
 * class documentation.
 *
 * ### Listeners
 *
 * You can also add event listeners to the surface using the `Observable` listener syntax. Supported events are:
 *
 * - mousedown
 * - mouseup
 * - mouseover
 * - mouseout
 * - mousemove
 * - mouseenter
 * - mouseleave
 * - click
 *
 * For example:
 *
        drawComponent.surface.on({
           'mousemove': function() {
                console.log('moving the mouse over the surface');   
            }
        });

     * than calling this method, especially if the surface is rendered immediately (e.g. due to
     * 'renderTo' in its config). For more information on how to create gradients in the Chart

     *  - **stops** - object - An object with numbers as keys (from 0 to 100) and style objects as values.
     * 
     *
     For example:
                drawComponent.surface.addGradient({

 *
 * The Draw Component is a surface in which sprites can be rendered. The Draw Component
 * manages and holds a `Surface` instance: an interface that has
 * an SVG or VML implementation depending on the browser capabilities and where
 * Sprites can be appended.
 * {@img Ext.draw.Component/Ext.draw.Component.png Ext.draw.Component component}
 * One way to create a draw component is:
 * 
 *     var drawComponent = Ext.create('Ext.draw.Component', {
 *         viewBox: false,
 *         items: [{
 *             type: 'circle',
 *             fill: '#79BB3F',
 *             radius: 100,
 *             x: 100,
 *             y: 100
 *         }]
 *     });
 *   
 *     Ext.create('Ext.Window', {
 *         width: 215,
 *         height: 235,
 *         layout: 'fit',
 *         items: [drawComponent]
 *     }).show();
 * 
 * In this case we created a draw component and added a sprite to it.
 * The *type* of the sprite is *circle* so if you run this code you'll see a yellow-ish
 * circle in a Window. When setting `viewBox` to `false` we are responsible for setting the object's position and
 * dimensions accordingly. 
 * 
 * You can also add sprites by using the surface's add method:
 *    
 *     drawComponent.surface.add({
 *         type: 'circle',
 *         fill: '#79BB3F',
 *         radius: 100,
 *         x: 100,
 *         y: 100
 *     });
 *  
 * For more information on Sprites, the core elements added to a draw component's surface,
 * refer to the Ext.draw.Sprite documentation.

/**
 * @class Ext.chart.Chart

 *
 * The Ext.chart package provides the capability to visualize data.
 * Each chart binds directly to an Ext.data.Store enabling automatic updates of the chart.
 * A chart configuration object has some overall styling options as well as an array of axes
 * and series. A chart instance example could look like:
 *
  <pre><code>
    Ext.create('Ext.chart.Chart', {
        renderTo: Ext.getBody(),
        width: 800,
        height: 600,
        animate: true,
        store: store1,
        shadow: true,
        theme: 'Category1',
        legend: {
            position: 'right'
        },
        axes: [ ...some axes options... ],
        series: [ ...some series options... ]
    });
  </code></pre>
 *
 * In this example we set the `width` and `height` of the chart, we decide whether our series are
 * animated or not and we select a store to be bound to the chart. We also turn on shadows for all series,
 * select a color theme `Category1` for coloring the series, set the legend to the right part of the chart and
 * then tell the chart to render itself in the body element of the document. For more information about the axes and
 * series configurations please check the documentation of each series (Line, Bar, Pie, etc).

 *     used to describe the visualization and also pointing to the actual shape (circle, rectangle, path, etc).
 *   - *`i`* The index of the element created (i.e the first created label, second created label, etc)
 *   - *`display`* The display type. May be <b>false</b> if the label is hidden
 *
 *  - **`onPlaceLabel(label, storeItem, item, i, display, animate)`** Called for updating the position of the label.
 *    The arguments of the method are:

 * An example of axis for a series (in this case for an area chart that has multiple layers of yFields) could be:

        grid: {
            odd: {
                opacity: 1,
                fill: '#ddd',
                stroke: '#bbb',

                degrees: 315
            }
        }
    }]
   </code></pre>
 * 
 * In this case we use a `Numeric` axis for displaying the values of the Area series and a `Category` axis for displaying the names of
 * the store elements. The numeric axis is placed on the left of the screen, while the category axis is placed at the bottom of the chart. 
 * Both the category and numeric axes have `grid` set, which means that horizontal and vertical lines will cover the chart background. In the 
 * category axis the labels will be rotated so they can fit the space better.

 * An axis to handle numeric values. This axis is used for quantitative data as

 * axis so that the values are bound to that. If no values are set, then the
 * scale will auto-adjust to the values.

 *
 * In this example we create an axis of Numeric type. We set a minimum value so that
 * even if all series have values greater than zero, the grid starts at zero. We bind
 * the axis onto the left part of the surface by setting <em>position</em> to <em>left</em>.
 * We bind three different store fields to this axis by setting <em>fields</em> to an array.
 * We set the title of the axis to <em>Number of Hits</em> by using the <em>title</em> property.
 * We use a <em>grid</em> configuration to set odd background rows to a certain style and even rows
 * to be transparent/ignored.

 * @class Ext.data.AbstractStore
 *
 * <p>AbstractStore is a superclass of {@link Ext.data.Store} and {@link Ext.data.TreeStore}. It's never used directly,
 * but offers a set of methods used by both of those subclasses.</p>
 * 
 * <p>We've left it here in the docs for reference purposes, but unless you need to make a whole new type of Store, what
 * you're probably looking for is {@link Ext.data.Store}. If you're still interested, here's a brief description of what 
 * AbstractStore is and is not.</p>
 * 
 * <p>AbstractStore provides the basic configuration for anything that can be considered a Store. It expects to be 
 * given a {@link Ext.data.Model Model} that represents the type of data in the Store. It also expects to be given a 
 * {@link Ext.data.proxy.Proxy Proxy} that handles the loading of data into the Store.</p>
 * 
 * <p>AbstractStore provides a few helpful methods such as {@link #load} and {@link #sync}, which load and save data
 * respectively, passing the requests through the configured {@link #proxy}. Both built-in Store subclasses add extra
 * behavior to each of these functions. Note also that each AbstractStore subclass has its own way of storing data - 
 * in {@link Ext.data.Store} the data is saved as a flat {@link Ext.util.MixedCollection MixedCollection}, whereas in
 * {@link Ext.data.TreeStore TreeStore} we use a {@link Ext.data.Tree} to maintain the data's hierarchy.</p>
 * 
 * TODO: Update these docs to explain about the sortable and filterable mixins.
 * <p>Finally, AbstractStore provides an API for sorting and filtering data via its {@link #sorters} and {@link #filters}
 * {@link Ext.util.MixedCollection MixedCollections}. Although this functionality is provided by AbstractStore, there's a
 * good description of how to use it in the introduction of {@link Ext.data.Store}.

 * @author Ed Spencer
 * @class Ext.data.Store
 * @extends Ext.data.AbstractStore
 *
 * <p>The Store class encapsulates a client side cache of {@link Ext.data.Model Model} objects. Stores load
 * data via a {@link Ext.data.proxy.Proxy Proxy}, and also provide functions for {@link #sort sorting},
 * {@link #filter filtering} and querying the {@link Ext.data.Model model} instances contained within it.</p>
 *
 * <p>Creating a Store is easy - we just tell it the Model and the Proxy to use to load and save its data:</p>
 *
<pre><code>
// Set up a {@link Ext.data.Model model} to use in our Store
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'firstName', type: 'string'},
        {name: 'lastName',  type: 'string'},
        {name: 'age',       type: 'int'},
        {name: 'eyeColor',  type: 'string'}
    ]
});

var myStore = new Ext.data.Store({
    model: 'User',
    proxy: {
        type: 'ajax',
        url : '/users.json',
        reader: {
            type: 'json',
            root: 'users'
        }
    },
    autoLoad: true
});
</code></pre>

 * <p>In the example above we configured an AJAX proxy to load data from the url '/users.json'. We told our Proxy
 * to use a {@link Ext.data.reader.Json JsonReader} to parse the response from the server into Model object -
 * {@link Ext.data.reader.Json see the docs on JsonReader} for details.</p>
 *
 * <p><u>Inline data</u></p>
 *
 * <p>Stores can also load data inline. Internally, Store converts each of the objects we pass in as {@link #data}
 * into Model instances:</p>
 *
<pre><code>
new Ext.data.Store({
    model: 'User',
    data : [
        {firstName: 'Ed',    lastName: 'Spencer'},
        {firstName: 'Tommy', lastName: 'Maintz'},
        {firstName: 'Aaron', lastName: 'Conran'},
        {firstName: 'Jamie', lastName: 'Avins'}
    ]
});
</code></pre>
 *
 * <p>Loading inline data using the method above is great if the data is in the correct format already (e.g. it doesn't need
 * to be processed by a {@link Ext.data.reader.Reader reader}). If your inline data requires processing to decode the data structure,
 * use a {@link Ext.data.proxy.Memory MemoryProxy} instead (see the {@link Ext.data.proxy.Memory MemoryProxy} docs for an example).</p>
 *
 * <p>Additional data can also be loaded locally using {@link #add}.</p>
 *
 * <p><u>Loading Nested Data</u></p>
 *
 * <p>Applications often need to load sets of associated data - for example a CRM system might load a User and her Orders.
 * Instead of issuing an AJAX request for the User and a series of additional AJAX requests for each Order, we can load a nested dataset
 * and allow the Reader to automatically populate the associated models. Below is a brief example, see the {@link Ext.data.reader.Reader} intro
 * docs for a full explanation:</p>
 *
<pre><code>
var store = new Ext.data.Store({
    autoLoad: true,
    model: "User",
    proxy: {
        type: 'ajax',
        url : 'users.json',
        reader: {
            type: 'json',
            root: 'users'
        }
    }
});
</code></pre>
 *
 * <p>Which would consume a response like this:</p>
 *
<pre><code>
{
    "users": [
        {
            "id": 1,
            "name": "Ed",
            "orders": [
                {
                    "id": 10,
                    "total": 10.76,
                    "status": "invoiced"
                },
                {
                    "id": 11,
                    "total": 13.45,
                    "status": "shipped"
                }
            ]
        }
    ]
}
</code></pre>
 *
 * <p>See the {@link Ext.data.reader.Reader} intro docs for a full explanation.</p>
 *
 * <p><u>Filtering and Sorting</u></p>
 *
 * <p>Stores can be sorted and filtered - in both cases either remotely or locally. The {@link #sorters} and {@link #filters} are
 * held inside {@link Ext.util.MixedCollection MixedCollection} instances to make them easy to manage. Usually it is sufficient to
 * either just specify sorters and filters in the Store configuration or call {@link #sort} or {@link #filter}:
 *
<pre><code>
var store = new Ext.data.Store({
    model: 'User',
    sorters: [
        {
            property : 'age',
            direction: 'DESC'
        },
        {
            property : 'firstName',
            direction: 'ASC'
        }
    ],

    filters: [
        {
            property: 'firstName',
            value   : /Ed/
        }
    ]
});
</code></pre>
 *
 * <p>The new Store will keep the configured sorters and filters in the MixedCollection instances mentioned above. By default, sorting
 * and filtering are both performed locally by the Store - see {@link #remoteSort} and {@link #remoteFilter} to allow the server to
 * perform these operations instead.</p>
 *
 * <p>Filtering and sorting after the Store has been instantiated is also easy. Calling {@link #filter} adds another filter to the Store
 * and automatically filters the dataset (calling {@link #filter} with no arguments simply re-applies all existing filters). Note that by
 * default {@link #sortOnFilter} is set to true, which means that your sorters are automatically reapplied if using local sorting.</p>
 *
<pre><code>
store.filter('eyeColor', 'Brown');
</code></pre>
 *
 * <p>Change the sorting at any time by calling {@link #sort}:</p>
 *
<pre><code>
store.sort('height', 'ASC');
</code></pre>
 *
 * <p>Note that all existing sorters will be removed in favor of the new sorter data (if {@link #sort} is called with no arguments,
 * the existing sorters are just reapplied instead of being removed). To keep existing sorters and add new ones, just add them
 * to the MixedCollection:</p>
 *
<pre><code>
store.sorters.add(new Ext.util.Sorter({
    property : 'shoeSize',
    direction: 'ASC'
}));

store.sort();
</code></pre>
 *
 * <p><u>Registering with StoreManager</u></p>
 *
 * <p>Any Store that is instantiated with a {@link #storeId} will automatically be registed with the {@link Ext.data.StoreManager StoreManager}.
 * This makes it easy to reuse the same store in multiple views:</p>
 *
 <pre><code>
//this store can be used several times
new Ext.data.Store({
    model: 'User',
    storeId: 'usersStore'
});

new Ext.List({
    store: 'usersStore',

    //other config goes here
});

new Ext.view.View({
    store: 'usersStore',

    //other config goes here
});
</code></pre>
 *
 * <p><u>Further Reading</u></p>
 *
 * <p>Stores are backed up by an ecosystem of classes that enables their operation. To gain a full understanding of these
 * pieces and how they fit together, see:</p>
 *

/**
 * @class Ext.chart.series.Series
 * 
 * Series is the abstract class containing the common logic to all chart series. Series includes 
 * methods from Labels, Highlights, Tips and Callouts mixins. This class implements the logic of handling 
 * mouse events, animating, hiding, showing all elements and returning the color of the series to be used as a legend item.
 *
 * ## Listeners
 *
 * The series class supports listeners via the Observable syntax. Some of these listeners are:
 *
 *  - `itemmouseup` When the user interacts with a marker.
 *  - `itemmousedown` When the user interacts with a marker.
 *  - `itemmousemove` When the user iteracts with a marker.
 *  - `afterrender` Will be triggered when the animation ends or when the series has been rendered completely.
 *
 * For example:
 *
 *     series: [{
 *             type: 'column',
 *             axis: 'left',
 *             listeners: {
 *                     'afterrender': function() {
 *                             console('afterrender');
 *                     }
 *             },
 *             xField: 'category',
 *             yField: 'data1'
 *     }]

 <p>
  In this configuration we set `area` as the type for the series, set highlighting options to true for highlighting elements on hover, 
  take the left axis to measure the data in the area series, set as xField (x values) the name field of each element in the store, 
  and as yFields (aggregated layers) seven data fields from the same store. Then we override some theming styles by adding some opacity 
  to the style object.

  Creates a Line Chart. A Line Chart is a useful visualization technique to display quantitative information for different 
  categories or other real values (as opposed to the bar chart), that can show some progression (or regression) in the dataset.
  As with all other series, the Line Series must be appended in the *series* Chart array configuration. See the Chart

 <p> 
  In this configuration we're adding two series (or lines), one bound to the `data1` property of the store and the other to `data3`. The type for both configurations is 
  `line`. The `xField` for both series is the same, the name propert of the store. Both line series share the same axis, the left axis. You can set particular marker 
  configuration by adding properties onto the markerConfig object. Both series have an object as highlight so that markers animate smoothly to the properties in highlight 
  when hovered. The second series has `fill=true` which means that the line will also have an area below it of the same color.

 * In this configuration we set `pie` as the type for the series, set an object with specific style properties for highlighting options 
 * (triggered when hovering elements). We also set true to `showInLegend` so all the pie slices can be represented by a legend item. 
 * We set `data1` as the value of the field to determine the angle span for each pie slice. We also set a label configuration object 
 * where we set the field name of the store field to be renderer as text for the label. The labels will also be displayed rotated. 
 * We set `contrast` to `true` to flip the color of the label if it is to similar to the background color. Finally, we set the font family 
 * and size through the `font` parameter.

 * In this configuration we add three series to the chart. Each of these series is bound to the same categories field, `name` but bound to different properties for each category,
 * `data1`, `data2` and `data3` respectively. All series display markers by having `showMarkers` enabled. The configuration for the markers of each series can be set by adding properties onto 
 * the markerConfig object. Finally we override some theme styling properties by adding properties to the `style` object.

 * In this configuration we add three different categories of scatter series. Each of them is bound to a different field of the same data store, 
 * `data1`, `data2` and `data3` respectively. All x-fields for the series must be the same field, in this case `name`. 
 * Each scatter series has a different styling configuration for markers, specified by the `markerConfig` object. Finally we set the left axis as 
 * axis to show the current values of the elements.

 * <p>Small helper class to make creating {@link Ext.data.Store}s from Array data easier.
 * An ArrayStore will be automatically configured with a {@link Ext.data.reader.Array}.</p>
 *
 * <p>A store configuration would be something like:</p>
<pre><code>
var store = new Ext.data.ArrayStore({
    // store configs
    autoDestroy: true,
    storeId: 'myStore',
    // reader configs
    idIndex: 0,
    fields: [
       'company',
       {name: 'price', type: 'float'},
       {name: 'change', type: 'float'},
       {name: 'pctChange', type: 'float'},
       {name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}
    ]
});
</code></pre>
 * <p>This store is configured to consume a returned object of the form:
<pre><code>
var myData = [
    ['3m Co',71.72,0.02,0.03,'9/1 12:00am'],
    ['Alcoa Inc',29.01,0.42,1.47,'9/1 12:00am'],

    ['Wal-Mart Stores, Inc.',45.45,0.73,1.63,'9/1 12:00am']
];
</code></pre>
*

/**
 * @author Ed Spencer
 * @class Ext.data.BelongsToAssociation
 * @extends Ext.data.Association
 *
 * <p>Represents a many to one association with another model. The owner model is expected to have
 * a foreign key which references the primary key of the associated model:</p>
 *
<pre><code>
Ext.define('Category', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'id',   type: 'int'},
        {name: 'name', type: 'string'}
    ]
});

Ext.define('Product', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'id',          type: 'int'},
        {name: 'category_id', type: 'int'},
        {name: 'name',        type: 'string'}
    ],
    // we can use the belongsTo shortcut on the model to create a belongsTo association
    belongsTo: {type: 'belongsTo', model: 'Category'}
});
</code></pre>
 * <p>In the example above we have created models for Products and Categories, and linked them together
 * by saying that each Product belongs to a Category. This automatically links each Product to a Category
 * based on the Product's category_id, and provides new functions on the Product model:</p>
 *
 * <p><u>Generated getter function</u></p>
 *
 * <p>The first function that is added to the owner model is a getter function:</p>
 *
<pre><code>
var product = new Product({
    id: 100,
    category_id: 20,
    name: 'Sneakers'
});

product.getCategory(function(category, operation) {
    //do something with the category object
    alert(category.get('id')); //alerts 20
}, this);
</code></pre>
*
 * <p>The getCategory function was created on the Product model when we defined the association. This uses the
 * Category's configured {@link Ext.data.proxy.Proxy proxy} to load the Category asynchronously, calling the provided
 * callback when it has loaded.</p>
 *
 * <p>The new getCategory function will also accept an object containing success, failure and callback properties
 * - callback will always be called, success will only be called if the associated model was loaded successfully
 * and failure will only be called if the associatied model could not be loaded:</p>
 *
<pre><code>
product.getCategory({
    callback: function(category, operation) {}, //a function that will always be called
    success : function(category, operation) {}, //a function that will only be called if the load succeeded
    failure : function(category, operation) {}, //a function that will only be called if the load did not succeed
    scope   : this //optionally pass in a scope object to execute the callbacks in
});
</code></pre>
 *
 * <p>In each case above the callbacks are called with two arguments - the associated model instance and the
 * {@link Ext.data.Operation operation} object that was executed to load that instance. The Operation object is
 * useful when the instance could not be loaded.</p>
 *
 * <p><u>Generated setter function</u></p>
 *
 * <p>The second generated function sets the associated model instance - if only a single argument is passed to
 * the setter then the following two calls are identical:</p>
 *
<pre><code>
//this call
product.setCategory(10);

//is equivalent to this call:
product.set('category_id', 10);
</code></pre>
 * <p>If we pass in a second argument, the model will be automatically saved and the second argument passed to
 * the owner model's {@link Ext.data.Model#save save} method:</p>
<pre><code>
product.setCategory(10, function(product, operation) {
    //the product has been saved
    alert(product.get('category_id')); //now alerts 10
});

//alternative syntax:
product.setCategory(10, {
    callback: function(product, operation), //a function that will always be called
    success : function(product, operation), //a function that will only be called if the load succeeded
    failure : function(product, operation), //a function that will only be called if the load did not succeed
    scope   : this //optionally pass in a scope object to execute the callbacks in
})
</code></pre>
*
 * <p><u>Customisation</u></p>
 *
 * <p>Associations reflect on the models they are linking to automatically set up properties such as the
 * {@link #primaryKey} and {@link #foreignKey}. These can alternatively be specified:</p>
 *
<pre><code>
Ext.define('Product', {
    fields: [...],

    associations: [
        {type: 'belongsTo', model: 'Category', primaryKey: 'unique_id', foreignKey: 'cat_id'}
    ]
});
 </code></pre>
 *
 * <p>Here we replaced the default primary key (defaults to 'id') and foreign key (calculated as 'category_id')
 * with our own settings. Usually this will not be needed.</p>

/**
 * @class Ext.direct.Manager
 * <p><b><u>Overview</u></b></p>
 *
 * <p>Ext.Direct aims to streamline communication between the client and server
 * by providing a single interface that reduces the amount of common code
 * typically required to validate data and handle returned data packets
 * (reading data, error conditions, etc).</p>
 *
 * <p>The Ext.direct namespace includes several classes for a closer integration
 * with the server-side. The Ext.data namespace also includes classes for working
 * with Ext.data.Stores which are backed by data from an Ext.Direct method.</p>
 *
 * <p><b><u>Specification</u></b></p>
 *
 * <p>For additional information consult the
 * <a href="http://sencha.com/products/extjs/extdirect">Ext.Direct Specification</a>.</p>
 *
 * <p><b><u>Providers</u></b></p>
 *
 * <p>Ext.Direct uses a provider architecture, where one or more providers are
 * used to transport data to and from the server. There are several providers
 * that exist in the core at the moment:</p><div class="mdetail-params"><ul>
 *
 * <li>{@link Ext.direct.JsonProvider JsonProvider} for simple JSON operations</li>
 * <li>{@link Ext.direct.PollingProvider PollingProvider} for repeated requests</li>
 * <li>{@link Ext.direct.RemotingProvider RemotingProvider} exposes server side
 * on the client.</li>
 * </ul></div>
 *
 * <p>A provider does not need to be invoked directly, providers are added via
 * {@link Ext.direct.Manager}.{@link Ext.direct.Manager#add add}.</p>
 *
 * <p><b><u>Router</u></b></p>
 *
 * <p>Ext.Direct utilizes a "router" on the server to direct requests from the client
 * to the appropriate server-side method. Because the Ext.Direct API is completely
 * platform-agnostic, you could completely swap out a Java based server solution
 * and replace it with one that uses C# without changing the client side JavaScript
 * at all.</p>
 *
 * <p><b><u>Server side events</u></b></p>
 *
 * <p>Custom events from the server may be handled by the client by adding
 * listeners, for example:</p>
 * <pre><code>
{"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}

// add a handler for a 'message' event sent by the server
Ext.direct.Manager.on('message', function(e){
    out.append(String.format('&lt;p>&lt;i>{0}&lt;/i>&lt;/p>', e.data));
            out.el.scrollTo('t', 100000, true);
});
 * </code></pre>

/**
 * @class Ext.data.proxy.Direct
 * @extends Ext.data.proxy.Server
 * 
 * This class is used to send requests to the server using {@link Ext.direct}. When a request is made,
 * the transport mechanism is handed off to the appropriate {@link Ext.direct.RemotingProvider Provider}
 * to complete the call.
 * 
 * ## Specifying the function
 * This proxy expects a Direct remoting method to be passed in order to be able to complete requests.
 * This can be done by specifying the {@link #directFn} configuration. This will use the same direct
 * method for all requests. Alternatively, you can provide an {@link #api} configuration. This
 * allows you to specify a different remoting method for each CRUD action.
 * 
 * ## Paramaters
 * This proxy provides options to help configure which parameters will be sent to the server.
 * By specifying the {@link #paramsAsHash} option, it will send an object literal containing each
 * of the passed parameters. The {@link #paramOrder} option can be used to specify the order in which
 * the remoting method parameters are passed.
 * 
 * ## Example Usage
 * 
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         fields: ['firstName', 'lastName'],
 *         proxy: {
 *             type: 'direct',
 *             directFn: MyApp.getUsers,
 *             paramOrder: 'id' // Tells the proxy to pass the id as the first parameter to the remoting method.
 *         }
 *     });

 * 
 * <p><u>Customization</u></p>
 * 
 * <p>The Inflector comes with a default set of US English pluralization rules. These can be augmented with additional
 * rules if the default rules do not meet your application's requirements, or swapped out entirely for other languages.
 * Here is how we might add a rule that pluralizes "ox" to "oxen":</p>
 * 
<pre><code>
Ext.util.Inflector.plural(/^(ox)$/i, "$1en");
</code></pre>
 * 
 * <p>Each rule consists of two items - a regular expression that matches one or more rules, and a replacement string.
 * In this case, the regular expression will only match the string "ox", and will replace that match with "oxen". 
 * Here's how we could add the inverse rule:</p>
 * 
<pre><code>
Ext.util.Inflector.singular(/^(ox)en$/i, "$1");

 * @author Ed Spencer
 * @class Ext.data.HasManyAssociation
 * @extends Ext.data.Association
 * 
 * <p>Represents a one-to-many relationship between two models. Usually created indirectly via a model definition:</p>
 * 
<pre><code>
Ext.define('Product', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'id',      type: 'int'},
        {name: 'user_id', type: 'int'},
        {name: 'name',    type: 'string'}
    ]
});

Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'id',   type: 'int'},
        {name: 'name', type: 'string'}
    ],
    // we can use the hasMany shortcut on the model to create a hasMany association
    hasMany: {model: 'Product', name: 'products'}
});
</pre></code>
* 
 * <p>Above we created Product and User models, and linked them by saying that a User hasMany Products. This gives
 * us a new function on every User instance, in this case the function is called 'products' because that is the name
 * we specified in the association configuration above.</p>
 * 
 * <p>This new function returns a specialized {@link Ext.data.Store Store} which is automatically filtered to load
 * only Products for the given model instance:</p>
 * 
<pre><code>
//first, we load up a User with id of 1
var user = Ext.ModelManager.create({id: 1, name: 'Ed'}, 'User');

//the user.products function was created automatically by the association and returns a {@link Ext.data.Store Store}
//the created store is automatically scoped to the set of Products for the User with id of 1
var products = user.products();

//we still have all of the usual Store functions, for example it's easy to add a Product for this User
products.add({
    name: 'Another Product'
});

//saves the changes to the store - this automatically sets the new Product's user_id to 1 before saving
products.sync();
</code></pre>
 * 
 * <p>The new Store is only instantiated the first time you call products() to conserve memory and processing time,
 * though calling products() a second time returns the same store instance.</p>
 * 
 * <p><u>Custom filtering</u></p>
 * 
 * <p>The Store is automatically furnished with a filter - by default this filter tells the store to only return
 * records where the associated model's foreign key matches the owner model's primary key. For example, if a User
 * with ID = 100 hasMany Products, the filter loads only Products with user_id == 100.</p>
 * 
 * <p>Sometimes we want to filter by another field - for example in the case of a Twitter search application we may
 * have models for Search and Tweet:</p>
 * 
<pre><code>
Ext.define('Search', {
    extend: 'Ext.data.Model',
    fields: [
        'id', 'query'
    ],

    hasMany: {
        model: 'Tweet',
        name : 'tweets',
        filterProperty: 'query'
    }
});

Ext.define('Tweet', {
    extend: 'Ext.data.Model',
    fields: [
        'id', 'text', 'from_user'
    ]
});

//returns a Store filtered by the filterProperty
var store = new Search({query: 'Sencha Touch'}).tweets();
</code></pre>
 * 
 * <p>The tweets association above is filtered by the query property by setting the {@link #filterProperty}, and is
 * equivalent to this:</p>
 * 
<pre><code>
var store = new Ext.data.Store({
    model: 'Tweet',
    filters: [
        {
            property: 'query',
            value   : 'Sencha Touch'
        }

 * A JsonPStore will be automatically configured with a {@link Ext.data.reader.Json} and a {@link Ext.data.proxy.JsonP JsonPProxy}.</p>
 * <p>A store configuration would be something like:<pre><code>

    url: 'get-images.php',

    idProperty: 'name',
    fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
});
 * </code></pre></p>
 * <p>This store is configured to consume a returned object of the form:<pre><code>
stcCallback({
    images: [
        {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)},

 * <p>Where stcCallback is the callback name passed in the request to the remote domain. See {@link Ext.data.proxy.JsonP JsonPProxy}
 * for details of how this works.</p>
 * An object literal of this form could also be used as the {@link #data} config option.</p>

 * the hierarchical tree structure combined with a store. This class is generally used
 * in conjunction with {@link Ext.tree.Panel}. This class also relays many events from
 * the Tree for convenience.

 * ## Using Models
 * If no Model is specified, an implicit model will be created that implements {@link Ext.data.NodeInterface}.
 * The standard Tree fields will also be copied onto the Model for maintaining their state.
 * 
 * ## Reading Nested Data
 * For the tree to read nested data, the {@link Ext.data.Reader} must be configured with a root property,
 * so the reader can find nested data for each node. If a root is not specified, it will default to
 * 'children'.

/**
 * @author Ed Spencer
 * @class Ext.data.proxy.JsonP
 * @extends Ext.data.proxy.Server
 *
 * <p>JsonPProxy is useful when you need to load data from a domain other than the one your application is running
 * on. If your application is running on http://domainA.com it cannot use {@link Ext.data.proxy.Ajax Ajax} to load its
 * data from http://domainB.com because cross-domain ajax requests are prohibited by the browser.</p>
 *
 * <p>We can get around this using a JsonPProxy. JsonPProxy injects a &lt;script&gt; tag into the DOM whenever
 * an AJAX request would usually be made. Let's say we want to load data from http://domainB.com/users - the script tag
 * that would be injected might look like this:</p>
 *
<pre><code>
&lt;script src="http://domainB.com/users?callback=someCallback"&gt;&lt;/script&gt;
</code></pre>
 *
 * <p>When we inject the tag above, the browser makes a request to that url and includes the response as if it was any
 * other type of JavaScript include. By passing a callback in the url above, we're telling domainB's server that we
 * want to be notified when the result comes in and that it should call our callback function with the data it sends
 * back. So long as the server formats the response to look like this, everything will work:</p>
 *
<pre><code>
someCallback({
    users: [
        {
            id: 1,
            name: "Ed Spencer",
            email: "ed@sencha.com"
        }
    ]
});
</code></pre>
 *
 * <p>As soon as the script finishes loading, the 'someCallback' function that we passed in the url is called with the
 * JSON object that the server returned.</p>
 *
 * <p>JsonPProxy takes care of all of this automatically. It formats the url you pass, adding the callback
 * parameter automatically. It even creates a temporary callback function, waits for it to be called and then puts
 * the data into the Proxy making it look just like you loaded it through a normal {@link Ext.data.proxy.Ajax AjaxProxy}.
 * Here's how we might set that up:</p>
 *
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email']
});

var store = new Ext.data.Store({
    model: 'User',
    proxy: {
        type: 'jsonp',
        url : 'http://domainB.com/users'
    }
});

store.load();
</code></pre>
 *
 * <p>That's all we need to do - JsonPProxy takes care of the rest. In this case the Proxy will have injected a
 * script tag like this:
 *
<pre><code>
&lt;script src="http://domainB.com/users?callback=stcCallback001" id="stcScript001"&gt;&lt;/script&gt;
</code></pre>
 *
 * <p><u>Customization</u></p>
 *
 * <p>Most parts of this script tag can be customized using the {@link #callbackParam}, {@link #callbackPrefix} and
 * {@link #scriptIdPrefix} configurations. For example:
 *
<pre><code>
var store = new Ext.data.Store({
    model: 'User',
    proxy: {
        type: 'jsonp',
        url : 'http://domainB.com/users',
        callbackParam: 'theCallbackFunction',
        callbackPrefix: 'ABC',
        scriptIdPrefix: 'injectedScript'
    }
});

store.load();
</code></pre>
 *
 * <p>Would inject a script tag like this:</p>
 *
<pre><code>
&lt;script src="http://domainB.com/users?theCallbackFunction=ABC001" id="injectedScript001"&gt;&lt;/script&gt;
</code></pre>
 *
 * <p><u>Implementing on the server side</u></p>
 *
 * <p>The remote server side needs to be configured to return data in this format. Here are suggestions for how you
 * might achieve this using Java, PHP and ASP.net:</p>
 *
 * <p>Java:</p>
 *
<pre><code>
boolean jsonP = false;
String cb = request.getParameter("callback");
if (cb != null) {
    jsonP = true;
    response.setContentType("text/javascript");
} else {
    response.setContentType("application/x-json");
}
Writer out = response.getWriter();
if (jsonP) {
    out.write(cb + "(");
}
out.print(dataBlock.toJsonString());
if (jsonP) {
    out.write(");");
}
</code></pre>
 *
 * <p>PHP:</p>
 *
<pre><code>
$callback = $_REQUEST['callback'];

// Create the output object.
$output = array('a' => 'Apple', 'b' => 'Banana');

//start output
if ($callback) {
    header('Content-Type: text/javascript');
    echo $callback . '(' . json_encode($output) . ');';
} else {
    header('Content-Type: application/x-json');
    echo json_encode($output);
}
</code></pre>
 *
 * <p>ASP.net:</p>
 *
<pre><code>
String jsonString = "{success: true}";
String cb = Request.Params.Get("callback");
String responseString = "";
if (!String.IsNullOrEmpty(cb)) {
    responseString = cb + "(" + jsonString + ")";
} else {
    responseString = jsonString;
}
Response.Write(responseString);
</code></pre>

 * @author Ed Spencer
 * @class Ext.data.proxy.LocalStorage
 * @extends Ext.data.proxy.WebStorage
 * 
 * <p>The LocalStorageProxy uses the new HTML5 localStorage API to save {@link Ext.data.Model Model} data locally on
 * the client browser. HTML5 localStorage is a key-value store (e.g. cannot save complex objects like JSON), so
 * LocalStorageProxy automatically serializes and deserializes data when saving and retrieving it.</p>
 * 
 * <p>localStorage is extremely useful for saving user-specific information without needing to build server-side 
 * infrastructure to support it. Let's imagine we're writing a Twitter search application and want to save the user's
 * searches locally so they can easily perform a saved search again later. We'd start by creating a Search model:</p>
 * 
<pre><code>
Ext.define('Search', {
    fields: ['id', 'query'],
    extend: 'Ext.data.Model',
    proxy: {
        type: 'localstorage',
        id  : 'twitter-Searches'
    }
});
</code></pre>
 * 
 * <p>Our Search model contains just two fields - id and query - plus a Proxy definition. The only configuration we
 * need to pass to the LocalStorage proxy is an {@link #id}. This is important as it separates the Model data in this
 * Proxy from all others. The localStorage API puts all data into a single shared namespace, so by setting an id we
 * enable LocalStorageProxy to manage the saved Search data.</p>
 * 
 * <p>Saving our data into localStorage is easy and would usually be done with a {@link Ext.data.Store Store}:</p>
 * 
<pre><code>
//our Store automatically picks up the LocalStorageProxy defined on the Search model
var store = new Ext.data.Store({
    model: "Search"
});

//loads any existing Search data from localStorage
store.load();

//now add some Searches
store.add({query: 'Sencha Touch'});
store.add({query: 'Ext JS'});

//finally, save our Search data to localStorage
store.sync();
</code></pre>
 * 
 * <p>The LocalStorageProxy automatically gives our new Searches an id when we call store.sync(). It encodes the Model
 * data and places it into localStorage. We can also save directly to localStorage, bypassing the Store altogether:</p>
 * 
<pre><code>
var search = Ext.ModelManager.create({query: 'Sencha Animator'}, 'Search');

//uses the configured LocalStorageProxy to save the new Search to localStorage
search.save();
</code></pre>
 * 
 * <p><u>Limitations</u></p>
 * 
 * <p>If this proxy is used in a browser where local storage is not supported, the constructor will throw an error.
 * A local storage proxy requires a unique ID which is used as a key in which all record data are stored in the
 * local storage object.</p>
 * 
 * <p>It's important to supply this unique ID as it cannot be reliably determined otherwise. If no id is provided
 * but the attached store has a storeId, the storeId will be used. If neither option is presented the proxy will
 * throw an error.</p>

 * @author Ed Spencer
 * @class Ext.data.proxy.Rest
 * @extends Ext.data.proxy.Ajax
 * 
 * <p>RestProxy is a specialization of the {@link Ext.data.proxy.Ajax AjaxProxy} which simply maps the four actions 
 * (create, read, update and destroy) to RESTful HTTP verbs. For example, let's set up a {@link Ext.data.Model Model}
 * with an inline RestProxy</p>
 * 
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email'],

    proxy: {
        type: 'rest',
        url : '/users'
    }
});
</code></pre>
 * 
 * <p>Now we can create a new User instance and save it via the RestProxy. Doing this will cause the Proxy to send a
 * POST request to '/users':
 * 
<pre><code>
var user = Ext.ModelManager.create({name: 'Ed Spencer', email: 'ed@sencha.com'}, 'User');

user.save(); //POST /users
</code></pre>
 * 
 * <p>Let's expand this a little and provide a callback for the {@link Ext.data.Model#save} call to update the Model
 * once it has been created. We'll assume the creation went successfully and that the server gave this user an ID of 
 * 123:</p>
 * 
<pre><code>
user.save({
    success: function(user) {
        user.set('name', 'Khan Noonien Singh');

        user.save(); //PUT /users/123
    }
});
</code></pre>
 * 
 * <p>Now that we're no longer creating a new Model instance, the request method is changed to an HTTP PUT, targeting
 * the relevant url for that user. Now let's delete this user, which will use the DELETE method:</p>
 * 
<pre><code>
    user.destroy(); //DELETE /users/123
</code></pre>
 * 
 * <p>Finally, when we perform a load of a Model or Store, RestProxy will use the GET method:</p>
 * 
<pre><code>
//1. Load via Store

//the Store automatically picks up the Proxy from the User model
var store = new Ext.data.Store({
    model: 'User'
});

store.load(); //GET /users

//2. Load directly from the Model

//GET /users/123
Ext.ModelManager.getModel('User').load(123, {
    success: function(user) {
        console.log(user.getId()); //outputs 123
    }
});
</code></pre>
 * 
 * <p><u>Url generation</u></p>
 * 
 * <p>RestProxy is able to automatically generate the urls above based on two configuration options - {@link #appendId}
 * and {@link #format}. If appendId is true (it is by default) then RestProxy will automatically append the ID of the 
 * Model instance in question to the configured url, resulting in the '/users/123' that we saw above.</p>
 * 
 * <p>If the request is not for a specific Model instance (e.g. loading a Store), the url is not appended with an id. 
 * RestProxy will automatically insert a '/' before the ID if one is not already present.</p>
 * 
<pre><code>
new Ext.data.proxy.Rest({
    url: '/users',
    appendId: true //default
});

// Collection url: /users
// Instance url  : /users/123
</code></pre>
 * 
 * <p>RestProxy can also optionally append a format string to the end of any generated url:</p>
 * 
<pre><code>
new Ext.data.proxy.Rest({
    url: '/users',
    format: 'json'
});

// Collection url: /users.json
// Instance url  : /users/123.json
</code></pre>
 * 
 * <p>If further customization is needed, simply implement the {@link #buildUrl} method and add your custom generated
 * url onto the {@link Ext.data.Request Request} object that is passed to buildUrl. See 
 * <a href="source/RestProxy.html#method-Ext.data.proxy.Rest-buildUrl">RestProxy's implementation</a> for an example of
 * how to achieve this.</p>
 * 
 * <p>Note that RestProxy inherits from {@link Ext.data.proxy.Ajax AjaxProxy}, which already injects all of the sorter,
 * filter, group and paging options into the generated url. See the {@link Ext.data.proxy.Ajax AjaxProxy docs} for more
 * details.</p>

/**
 * @author Ed Spencer
 * @class Ext.data.reader.Xml
 * @extends Ext.data.reader.Reader
 * 
 * <p>The XML Reader is used by a Proxy to read a server response that is sent back in XML format. This usually
 * happens as a result of loading a Store - for example we might create something like this:</p>
 * 
<pre><code>
Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email']
});

var store = new Ext.data.Store({
    model: 'User',
    proxy: {
        type: 'ajax',
        url : 'users.xml',
        reader: {
            type: 'xml',
            record: 'user'
        }
    }
});
</code></pre>
 * 
 * <p>The example above creates a 'User' model. Models are explained in the {@link Ext.data.Model Model} docs if you're
 * not already familiar with them.</p>
 * 
 * <p>We created the simplest type of XML Reader possible by simply telling our {@link Ext.data.Store Store}'s 
 * {@link Ext.data.proxy.Proxy Proxy} that we want a XML Reader. The Store automatically passes the configured model to the
 * Store, so it is as if we passed this instead:
 * 
<pre><code>
reader: {
    type : 'xml',
    model: 'User',
    record: 'user'
}
</code></pre>
 * 
 * <p>The reader we set up is ready to read data from our server - at the moment it will accept a response like this:</p>
 *
<pre><code>
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;user&gt;
    &lt;id&gt;1&lt;/id&gt;
    &lt;name&gt;Ed Spencer&lt;/name&gt;
    &lt;email&gt;ed@sencha.com&lt;/email&gt;
&lt;/user&gt;
&lt;user&gt;
    &lt;id&gt;2&lt;/id&gt;
    &lt;name&gt;Abe Elias&lt;/name&gt;
    &lt;email&gt;abe@sencha.com&lt;/email&gt;
&lt;/user&gt;
</code></pre>
 * 
 * <p>The XML Reader uses the configured {@link #record} option to pull out the data for each record - in this case we
 * set record to 'user', so each &lt;user&gt; above will be converted into a User model.</p>
 * 
 * <p><u>Reading other XML formats</u></p>
 * 
 * <p>If you already have your XML format defined and it doesn't look quite like what we have above, you can usually
 * pass XmlReader a couple of configuration options to make it parse your format. For example, we can use the 
 * {@link #root} configuration to parse data that comes back like this:</p>
 * 
<pre><code>
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;users&gt;
    &lt;user&gt;
        &lt;id&gt;1&lt;/id&gt;
        &lt;name&gt;Ed Spencer&lt;/name&gt;
        &lt;email&gt;ed@sencha.com&lt;/email&gt;
    &lt;/user&gt;
    &lt;user&gt;
        &lt;id&gt;2&lt;/id&gt;
        &lt;name&gt;Abe Elias&lt;/name&gt;
        &lt;email&gt;abe@sencha.com&lt;/email&gt;
    &lt;/user&gt;
&lt;/users&gt;
</code></pre>
 * 
 * <p>To parse this we just pass in a {@link #root} configuration that matches the 'users' above:</p>
 * 
<pre><code>
reader: {
    type  : 'xml',
    root  : 'users',
    record: 'user'
}
</code></pre>
 * 
 * <p>Note that XmlReader doesn't care whether your {@link #root} and {@link #record} elements are nested deep inside
 * a larger structure, so a response like this will still work:
 * 
<pre><code>
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;deeply&gt;
    &lt;nested&gt;
        &lt;xml&gt;
            &lt;users&gt;
                &lt;user&gt;
                    &lt;id&gt;1&lt;/id&gt;
                    &lt;name&gt;Ed Spencer&lt;/name&gt;
                    &lt;email&gt;ed@sencha.com&lt;/email&gt;
                &lt;/user&gt;
                &lt;user&gt;
                    &lt;id&gt;2&lt;/id&gt;
                    &lt;name&gt;Abe Elias&lt;/name&gt;
                    &lt;email&gt;abe@sencha.com&lt;/email&gt;
                &lt;/user&gt;
            &lt;/users&gt;
        &lt;/xml&gt;
    &lt;/nested&gt;
&lt;/deeply&gt;
</code></pre>
 * 
 * <p><u>Response metadata</u></p>
 * 
 * <p>The server can return additional data in its response, such as the {@link #totalProperty total number of records} 
 * and the {@link #successProperty success status of the response}. These are typically included in the XML response
 * like this:</p>
 * 
<pre><code>
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;total&gt;100&lt;/total&gt;
&lt;success&gt;true&lt;/success&gt;
&lt;users&gt;
    &lt;user&gt;
        &lt;id&gt;1&lt;/id&gt;
        &lt;name&gt;Ed Spencer&lt;/name&gt;
        &lt;email&gt;ed@sencha.com&lt;/email&gt;
    &lt;/user&gt;
    &lt;user&gt;
        &lt;id&gt;2&lt;/id&gt;
        &lt;name&gt;Abe Elias&lt;/name&gt;
        &lt;email&gt;abe@sencha.com&lt;/email&gt;
    &lt;/user&gt;
&lt;/users&gt;
</code></pre>
 * 
 * <p>If these properties are present in the XML response they can be parsed out by the XmlReader and used by the
 * Store that loaded it. We can set up the names of these properties by specifying a final pair of configuration 
 * options:</p>
 * 
<pre><code>
reader: {
    type: 'xml',
    root: 'users',
    totalProperty  : 'total',
    successProperty: 'success'
}
</code></pre>
 * 
 * <p>These final options are not necessary to make the Reader work, but can be useful when the server needs to report
 * an error or if it needs to indicate that there is a lot of data available of which only a subset is currently being
 * returned.</p>
 * 
 * <p><u>Response format</u></p>
 * 
 * <p><b>Note:</b> in order for the browser to parse a returned XML document, the Content-Type header in the HTTP 
 * response must be set to "text/xml" or "application/xml". This is very important - the XmlReader will not
 * work correctly otherwise.</p>

/**
 * @class Ext.draw.Sprite
 * @extends Object
 *
 * A Sprite is an object rendered in a Drawing surface. There are different options and types of sprites.
 * The configuration of a Sprite is an object with the following properties:
 *
 * - **type** - (String) The type of the sprite. Possible options are 'circle', 'path', 'rect', 'text', 'square'. 
 * - **width** - (Number) Used in rectangle sprites, the width of the rectangle.
 * - **height** - (Number) Used in rectangle sprites, the height of the rectangle.
 * - **size** - (Number) Used in square sprites, the dimension of the square.
 * - **radius** - (Number) Used in circle sprites, the radius of the circle.
 * - **x** - (Number) The position along the x-axis.
 * - **y** - (Number) The position along the y-axis.
 * - **path** - (Array) Used in path sprites, the path of the sprite written in SVG-like path syntax.
 * - **opacity** - (Number) The opacity of the sprite.
 * - **fill** - (String) The fill color.
 * - **stroke** - (String) The stroke color.
 * - **stroke-width** - (Number) The width of the stroke.
 * - **font** - (String) Used with text type sprites. The full font description. Uses the same syntax as the CSS `font` parameter.
 * - **text** - (String) Used with text type sprites. The text itself.
 * 
 * Additionally there are three transform objects that can be set with `setAttributes` which are `translate`, `rotate` and
 * `scale`.
 * 
 * For translate, the configuration object contains x and y attributes that indicate where to
 * translate the object. For example:
 * 
 *     sprite.setAttributes({
 *       translate: {
 *        x: 10,
 *        y: 10
 *       }
 *     }, true);
 * 
 * For rotation, the configuration object contains x and y attributes for the center of the rotation (which are optional),
 * and a `degrees` attribute that specifies the rotation in degrees. For example:
 * 
 *     sprite.setAttributes({
 *       rotate: {
 *        degrees: 90
 *       }
 *     }, true);
 * 
 * For scaling, the configuration object contains x and y attributes for the x-axis and y-axis scaling. For example:
 * 
 *     sprite.setAttributes({
 *       scale: {
 *        x: 10,
 *        y: 3
 *       }
 *     }, true);
 *
 * Sprites can be created with a reference to a {@link Ext.draw.Surface}
 *
 *      var drawComponent = Ext.create('Ext.draw.Component', options here...);
 *
 *      var sprite = Ext.create('Ext.draw.Sprite', {
 *          type: 'circle',
 *          fill: '#ff0',
 *          surface: drawComponent.surface,
 *          radius: 5
 *      });
 *
 * Sprites can also be added to the surface as a configuration object:
 *
 *      var sprite = drawComponent.surface.add({
 *          type: 'circle',
 *          fill: '#ff0',
 *          radius: 5
 *      });
 *
 * In order to properly apply properties and render the sprite we have to
 * `show` the sprite setting the option `redraw` to `true`:
 *
 *      sprite.show(true);
 *
 * The constructor configuration object of the Sprite can also be used and passed into the {@link Ext.draw.Surface}
 * add method to append a new sprite to the canvas. For example:
 *
 *     drawComponent.surface.add({
 *         type: 'circle',
 *         fill: '#ffc',
 *         radius: 100,
 *         x: 100,
 *         y: 100
 *     });

 * @class Ext.layout.container.Fit
 * @extends Ext.layout.container.AbstractFit
 * <p>This is a base class for layouts that contain <b>a single item</b> that automatically expands to fill the layout's
 * container.  This class is intended to be extended or created via the <tt>layout:'fit'</tt> {@link Ext.container.Container#layout}
 * config, and should generally not need to be created directly via the new keyword.</p>
 * <p>FitLayout does not have any direct config options (other than inherited ones).  To fit a panel to a container
 * using FitLayout, simply set layout:'fit' on the container and add a single panel to it.  If the container has
 * multiple panels, only the first one will be displayed.  
 * {@img Ext.layout.container.Fit/Ext.layout.container.Fit.png Ext.layout.container.Fit container layout}

 * <p>This layout manages multiple child Components, each is fit to the Container, where only a single child Component

 * This class is intended to be extended or created via the layout:'card' {@link Ext.container.Container#layout} config,
 * and should generally not need to be created directly via the new keyword.</p>
 * <p>The CardLayout's focal method is {@link #setActiveItem}.  Since only one panel is displayed at a time,
 * the only way to move from one Component to the next is by calling setActiveItem, passing the id or index of
 * the next panel to display.  The layout itself does not provide a user interface for handling this navigation,
 * so that functionality must be provided by the developer.</p>
 * <p>Containers that are configured with a card layout will have a method setActiveItem dynamically added to it.

/**
 * @class Ext.Action
 * <p>An Action is a piece of reusable functionality that can be abstracted out of any particular component so that it
 * can be usefully shared among multiple components.  Actions let you share handlers, configuration options and UI
 * updates across any components that support the Action interface (primarily {@link Ext.toolbar.Toolbar}, {@link Ext.button.Button}
 * and {@link Ext.menu.Menu} components).</p>
 * <p>Use a single Action instance as the config object for any number of UI Components which share the same configuration. The
 * Action not only supplies the configuration, but allows all Components based upon it to have a common set of methods
 * called at once through a single call to the Action.</p>
 * <p>Any Component that is to be configured with an Action must also support
 * the following methods:<ul>
 * <li><code>setText(string)</code></li>
 * <li><code>setIconCls(string)</code></li>
 * <li><code>setDisabled(boolean)</code></li>
 * <li><code>setVisible(boolean)</code></li>

 * <p>
 * The Editor class is used to provide inline editing for elements on the page. The editor
 * is backed by a {@link Ext.form.field.Field} that will be displayed to edit the underlying content.
 * The editor is a floating Component, when the editor is shown it is automatically aligned to
 * display over the top of the bound element it is editing. The Editor contains several options
 * for how to handle key presses:
 * <ul>
 * <li>{@link #completeOnEnter}</li>
 * <li>{@link #cancelOnEsc}</li>
 * <li>{@link #swallowKeys}</li>
 * </ul>
 * It also has options for how to use the value once the editor has been activated:
 * <ul>
 * <li>{@link #revertInvalid}</li>
 * <li>{@link #ignoreNoChange}</li>
 * <li>{@link #updateEl}</li>
 * </ul>
 * Sample usage:
 * </p>
 * <pre><code>
var editor = new Ext.Editor({
    updateEl: true, // update the innerHTML of the bound element when editing completes
    field: {
        xtype: 'textfield'
    }
});
var el = Ext.get('my-text'); // The element to 'edit'
editor.startEdit(el); // The value of the field will be taken as the innerHTML of the element.

/**
 * @class Ext.ProgressBar
 * @extends Ext.Component
 * <p>An updateable progress bar component.  The progress bar supports two different modes: manual and automatic.</p>
 * <p>In manual mode, you are responsible for showing, updating (via {@link #updateProgress}) and clearing the
 * progress bar as needed from your own code.  This method is most appropriate when you want to show progress
 * throughout an operation that has predictable points of interest at which you can update the control.</p>
 * <p>In automatic mode, you simply call {@link #wait} and let the progress bar run indefinitely, only clearing it
 * once the operation is complete.  You can optionally have the progress bar wait for a specific amount of time
 * and then clear itself.  Automatic mode is most appropriate for timed operations or asynchronous operations in
 * which you have no need for indicating intermediate progress.</p>
 * {@img Ext.ProgressBar/Ext.ProgressBar.png Ext.ProgressBar component}
 * Example Usage:
     var p = Ext.create('Ext.ProgressBar', {
       renderTo: Ext.getBody(),
       width: 300
    });

    //Wait for 5 seconds, then update the status el (progress bar will auto-reset)
    p.wait({
       interval: 500, //bar will move fast!
       duration: 50000,
       increment: 15,
       text: 'Updating...',
       scope: this,
       fn: function(){
          p.updateText('Done!');
       }
    });
 * @cfg {Float} value A floating point value between 0 and 1 (e.g., .5, defaults to 0)
 * @cfg {String} text The progress bar text (defaults to '')
 * @cfg {Mixed} textEl The element to render the progress text to (defaults to the progress
 * bar's internal text element)

    increment  Number        The number of progress update segments to display within the progress
                             bar (defaults to 10).  If the bar reaches the end and is still
                             updating, it will automatically wrap back to the beginning.
    text       String        Optional text to display in the progress bar element (defaults to '').

                             should be called by the same code after it resets the progress bar.
    scope      Object        The scope that is passed to the callback function (only applies when
                             duration and fn are both passed).

/**
 * @class Ext.container.Viewport
 * @extends Ext.container.Container

A specialized container representing the viewable application area (the browser viewport).

The Viewport renders itself to the document body, and automatically sizes itself to the size of
the browser viewport and manages window resizing. There may only be one Viewport created
in a page.

Like any {@link Ext.container.Container Container}, a Viewport will only perform sizing and positioning
on its child Components if you configure it with a {@link #layout}.

A Common layout used with Viewports is {@link Ext.layout.container.Border border layout}, but if the
required layout is simpler, a different layout should be chosen.

For example, to simply make a single child item occupy all available space, use {@link Ext.layout.container.Fit fit layout}.

To display one "active" item at full size from a choice of several child items, use {@link Ext.layout.container.Card card layout}.

Inner layouts are available by virtue of the fact that all {@link Ext.panel.Panel Panel}s
added to the Viewport, either through its {@link #items}, or through the items, or the {@link #add}
method of any of its child Panels may themselves have a layout.

The Viewport does not provide scrolling, so child Panels within the Viewport should provide
for scrolling if needed using the {@link #autoScroll} config.
{@img Ext.container.Viewport/Ext.container.Viewport.png Ext.container.Viewport component}
An example showing a classic application border layout:

    Ext.create('Ext.container.Viewport', {
        layout: 'border',
        renderTo: Ext.getBody(),
        items: [{
            region: 'north',
            html: '<h1 class="x-panel-header">Page Title</h1>',
            autoHeight: true,
            border: false,
            margins: '0 0 5 0'
        }, {

            title: 'Navigation',
            width: 150
            // could use a TreePanel or AccordionLayout for navigational items
        }, {
            region: 'south',
            title: 'South Panel',

/**
 * @class Ext.dd.DragZone
 * @extends Ext.dd.DragSource
 * <p>This class provides a container DD instance that allows dragging of multiple child source nodes.</p>
 * <p>This class does not move the drag target nodes, but a proxy element which may contain
 * any DOM structure you wish. The DOM element to show in the proxy is provided by either a
 * provided implementation of {@link #getDragData}, or by registered draggables registered with {@link Ext.dd.Registry}</p>
 * <p>If you wish to provide draggability for an arbitrary number of DOM nodes, each of which represent some
 * application object (For example nodes in a {@link Ext.view.View DataView}) then use of this class
 * is the most efficient way to "activate" those nodes.</p>
 * <p>By default, this class requires that draggable child nodes are registered with {@link Ext.dd.Registry}.
 * However a simpler way to allow a DragZone to manage any number of draggable elements is to configure
 * the DragZone with  an implementation of the {@link #getDragData} method which interrogates the passed
 * mouse event to see if it has taken place within an element, or class of elements. This is easily done
 * by using the event's {@link Ext.EventObject#getTarget getTarget} method to identify a node based on a
 * {@link Ext.DomQuery} selector. For example, to make the nodes of a DataView draggable, use the following
 * technique. Knowledge of the use of the DataView is required:</p><pre><code>
myDataView.on('render', function(v) {
    myDataView.dragZone = new Ext.dd.DragZone(v.getEl(), {

//      On receipt of a mousedown event, see if it is within a DataView node.
//      Return a drag data object if so.

//          Use the DataView's own itemSelector (a mandatory property) to
//          test if the mousedown is within one of the DataView's nodes.
            var sourceEl = e.getTarget(v.itemSelector, 10);

//          If the mousedown is within a DataView node, clone the node to produce
//          a ddel element for use by the drag proxy. Also add application data
//          to the returned data object.

/**
 * @class Ext.dd.DropZone
 * @extends Ext.dd.DropTarget

This class provides a container DD instance that allows dropping on multiple child target nodes.

By default, this class requires that child nodes accepting drop are registered with {@link Ext.dd.Registry}.
However a simpler way to allow a DropZone to manage any number of target elements is to configure the
DropZone with an implementation of {@link #getTargetFromEvent} which interrogates the passed
mouse event to see if it has taken place within an element, or class of elements. This is easily done
by using the event's {@link Ext.EventObject#getTarget getTarget} method to identify a node based on a
{@link Ext.DomQuery} selector.

Once the DropZone has detected through calling getTargetFromEvent, that the mouse is over
a drop target, that target is passed as the first parameter to {@link #onNodeEnter}, {@link #onNodeOver},
{@link #onNodeOut}, {@link #onNodeDrop}. You may configure the instance of DropZone with implementations
of these methods to provide application-specific behaviour for these events to update both
application state, and UI state.

For example to make a GridPanel a cooperating target with the example illustrated in
{@link Ext.dd.DragZone DragZone}, the following technique might be used:

    myGridPanel.on('render', function() {
        myGridPanel.dropZone = new Ext.dd.DropZone(myGridPanel.getView().scroller, {

            // If the mouse is over a grid row, return that node. This is
            // provided as the "target" parameter in all "onNodeXXXX" node event handling functions
            getTargetFromEvent: function(e) {
                return e.getTarget(myGridPanel.getView().rowSelector);
            },

            // On entry into a target node, highlight that node.
            onNodeEnter : function(target, dd, e, data){ 
                Ext.fly(target).addCls('my-row-highlight-class');
            },

            // On exit from a target node, unhighlight that node.
            onNodeOut : function(target, dd, e, data){ 
                Ext.fly(target).removeCls('my-row-highlight-class');
            },

            // While over a target node, return the default drop allowed class which
            // places a "tick" icon into the drag proxy.
            onNodeOver : function(target, dd, e, data){ 
                return Ext.dd.DropZone.prototype.dropAllowed;
            },

            // On node drop we can interrogate the target to find the underlying
            // application object that is the real target of the dragged data.
            // In this case, it is a Record in the GridPanel's Store.
            // We can use the data set up by the DragZone's getDragData method to read
            // any data we decided to attach in the DragZone's getDragData method.
            onNodeDrop : function(target, dd, e, data){
                var rowIndex = myGridPanel.getView().findRowIndex(target);
                var r = myGridPanel.getStore().getAt(rowIndex);
                Ext.Msg.alert('Drop gesture', 'Dropped Record id ' + data.draggedRecord.id +
                    ' on Record id ' + r.id);
                return true;
            }

/**
 * @class Ext.flash.Component
 * @extends Ext.Component
 *
 * A simple Component for displaying an Adobe Flash SWF movie. The movie will be sized and can participate
 * in layout like any other Component.
 *
 * This component requires the third-party SWFObject library version 2.2 or above. It is not included within
 * the ExtJS distribution, so you will have to include it into your page manually in order to use this component.
 * The SWFObject library can be downloaded from the [SWFObject project page](http://code.google.com/p/swfobject)
 * and then simply import it into the head of your HTML document:
 *
 *     <script type="text/javascript" src="path/to/local/swfobject.js"></script>
 *
 * ## Configuration
 *
 * This component allows several options for configuring how the target Flash movie is embedded. The most
 * important is the required {@link #url} which points to the location of the Flash movie to load. Other
 * configurations include:
 *
 * - {@link #backgroundColor}
 * - {@link #wmode}
 * - {@link #flashVars}
 * - {@link #flashParams}
 * - {@link #flashAttributes}
 *
 * ## Example usage:
 *
 *     var win = Ext.widget('window', {
 *         title: "It's a tiger!",
 *         layout: 'fit',
 *         width: 300,
 *         height: 300,
 *         x: 20,
 *         y: 20,
 *         resizable: true,
 *         items: {
 *             xtype: 'flash',
 *             url: 'tiger.swf'
 *         }
 *     });
 *     win.show();
 *
 * ## Express Install
 *
 * Adobe provides a tool called [Express Install](http://www.adobe.com/devnet/flashplayer/articles/express_install.html)
 * that offers users an easy way to upgrade their Flash player. If you wish to make use of this, you should set
 * the static EXPRESS\_INSTALL\_URL property to the location of your Express Install SWF file:
 *
 *     Ext.flash.Component.EXPRESS_INSTALL_URL = 'path/to/local/expressInstall.swf';
 *
 * @constructor
 * Creates a new Ext.flash.Component instance.
 * @param {Object} config The component configuration.

**NOTE**: This mixin is mainly for internal library use and most users should not need to use it directly. It
is more likely you will want to use one of the component classes that import this mixin, such as
{@link Ext.form.field.Base} or {@link Ext.form.FieldContainer}.

Use of this mixin does not make a component a field in the logical sense, meaning it does not provide any
logic or state related to values or validation; that is handled by the related {@link Ext.form.field.Field}
mixin. These two mixins may be used separately (for example {@link Ext.form.FieldContainer} is Labelable but not a
Field), or in combination (for example {@link Ext.form.field.Base} implements both and has logic for connecting the
two.)

Component classes which use this mixin should use the Field layout
or a derivation thereof to properly size and position the label and message according to the component config.
They must also call the {@link #initLabelable} method during component initialization to ensure the mixin gets
set up correctly.

/**
 * @class Ext.form.field.Field

This mixin provides a common interface for the logical behavior and state of form fields, including:

- Getter and setter methods for field values
- Events and methods for tracking value and validity changes
- Methods for triggering validation

**NOTE**: When implementing custom fields, it is most likely that you will want to extend the {@link Ext.form.field.Base}
component class rather than using this mixin directly, as BaseField contains additional logic for generating an
actual DOM complete with {@link Ext.form.Labelable label and error message} display and a form input field,
plus methods that bind the Field value getters and setters to the input field's value.

If you do want to implement this mixin directly and don't want to extend {@link Ext.form.field.Base}, then
you will most likely want to override the following methods with custom implementations: {@link #getValue},
{@link #setValue}, and {@link #getErrors}. Other methods may be overridden as needed but their base
implementations should be sufficient for common cases. You will also need to make sure that {@link #initField}
is called during the component's initialization.

 * <p>This class is intended to be extended or created via the layout: 'anchor' {@link Ext.layout.container.AbstractContainer#layout}
 * config, and should generally not need to be created directly via the new keyword.</p>
 * <p>AnchorLayout does not have any direct config options (other than inherited ones). By default,
 * AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the
 * container using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>.
 * If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating
 * anchor measurements based on it instead, allowing the container to be sized independently of the anchoring
 * logic if necessary.  
 * {@img Ext.layout.container.Anchor/Ext.layout.container.Anchor.png Ext.layout.container.Anchor container layout}
 * For example:
        Ext.create('Ext.Panel', {
                width: 500,
                height: 400,

     * @cfg {String} anchor
     * <p>This configuation option is to be applied to <b>child <tt>items</tt></b> of a container managed by
     * this layout (ie. configured with <tt>layout:'anchor'</tt>).</p><br/>
     *
     * <p>This value is what tells the layout how an item should be anchored to the container. <tt>items</tt>
     * added to an AnchorLayout accept an anchoring-specific config property of <b>anchor</b> which is a string
     * containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').
     * The following types of anchor values are supported:<div class="mdetail-params"><ul>
     *
     * <li><b>Percentage</b> : Any value between 1 and 100, expressed as a percentage.<div class="sub-desc">
     * The first anchor is the percentage width that the item should take up within the container, and the
     * second is the percentage height.  For example:<pre><code>
// two values specified
anchor: '100% 50%' // render item complete width of the container and
                   // 1/2 height of the container
// one value specified
anchor: '100%'     // the width value; the height will default to auto
     * </code></pre></div></li>
     *
     * <li><b>Offsets</b> : Any positive or negative integer value.<div class="sub-desc">
     * This is a raw adjustment where the first anchor is the offset from the right edge of the container,
     * and the second is the offset from the bottom edge. For example:<pre><code>
// two values specified
anchor: '-50 -100' // render item the complete width of the container
                   // minus 50 pixels and
                   // the complete height minus 100 pixels.
// one value specified
anchor: '-50'      // anchor value is assumed to be the right offset value
                   // bottom offset will default to 0
     * </code></pre></div></li>
     *
     * <li><b>Sides</b> : Valid values are <tt>'right'</tt> (or <tt>'r'</tt>) and <tt>'bottom'</tt>
     * (or <tt>'b'</tt>).<div class="sub-desc">
     * Either the container must have a fixed size or an anchorSize config value defined at render time in
     * order for these to have any effect.</div></li>
     *
     * <li><b>Mixed</b> : <div class="sub-desc">
     * Anchor values can also be mixed as needed.  For example, to render the width offset from the container
     * right edge by 50 pixels and 75% of the container's height use:
     * <pre><code>
anchor: '-50 75%'
     * </code></pre></div></li>

 * @class Ext.form.field.Base

Base class for form fields that provides default event handling, rendering, and other common functionality
needed by all form field types. Utilizes the {@link Ext.form.field.Field} mixin for value handling and validation,
and the {@link Ext.form.Labelable} mixin to provide label and error message display.

In most cases you will want to use a subclass, such as {@link Ext.form.field.Text} or {@link Ext.form.field.Checkbox},
rather than creating instances of this class directly. However if you are implementing a custom form field,
using this as the parent class is recommended.

__Values and Conversions__

Because BaseField implements the Field mixin, it has a main value that can be initialized with the
{@link #value} config and manipulated via the {@link #getValue} and {@link #setValue} methods. This main
value can be one of many data types appropriate to the current field, for instance a {@link Ext.form.field.Date Date}
field would use a JavaScript Date object as its value type. However, because the field is rendered as a HTML
input, this value data type can not always be directly used in the rendered field.

Therefore BaseField introduces the concept of a "raw value". This is the value of the rendered HTML input field,
and is normally a String. The {@link #getRawValue} and {@link #setRawValue} methods can be used to directly
work with the raw value, though it is recommended to use getValue and setValue in most cases.

Conversion back and forth between the main value and the raw value is handled by the {@link #valueToRaw} and
{@link #rawToValue} methods. If you are implementing a subclass that uses a non-String value data type, you
should override these methods to handle the conversion.

__Rendering__

The content of the field body is defined by the {@link #fieldSubTpl} XTemplate, with its argument data
created by the {@link #getSubTplData} method. Override this template and/or method to create custom
field renderings.

    // searchUrl when the Enter key is pressed.

        // Handle enter key presses, execute the search if the field has a value
        checkEnterKey: function(field, e) {
            var value = this.getValue();
            if (e.getKey() === e.ENTER && !Ext.isEmpty(value)) {
                location.href = Ext.String.format(this.searchUrl, value);

/**
 * @class Ext.form.field.Text
 * @extends Ext.form.field.Base
 
A basic text field.  Can be used as a direct replacement for traditional text inputs,
or as the base class for more sophisticated input controls (like {@link Ext.form.field.TextArea}
and {@link Ext.form.field.ComboBox}). Has support for empty-field placeholder values (see {@link #emptyText}).

#Validation#

The Text field has a useful set of validations built in:

- {@link #allowBlank} for making the field required
- {@link #minLength} for requiring a minimum value length
- {@link #maxLength} for setting a maximum value length (with {@link #enforceMaxLength} to add it
  as the `maxlength` attribute on the input element)
- {@link regex} to specify a custom regular expression for validation

In addition, custom validations may be added:
 
- {@link #vtype} specifies a virtual type implementation from {@link Ext.form.field.VTypes} which can contain
  custom validation logic
- {@link #validator} allows a custom arbitrary function to be called during validation

The details around how and when each of these validation options get used are described in the
documentation for {@link #getErrors}.

By default, the field value is checked for validity immediately while the user is typing in the
field. This can be controlled with the {@link #validateOnChange}, {@link #checkChangeEvents}, and
{@link #checkChangeBugger} configurations. Also see the details on Form Validation in the
{@link Ext.form.Panel} class documentation.

#Masking and Character Stripping#

Text fields can be configured with custom regular expressions to be applied to entered values before
validation: see {@link #maskRe} and {@link #stripCharsRe} for details.

    /**
Validates a value according to the field's validation rules and returns an array of errors
for any failing validations. Validation rules are processed in the following order:

1. **Field specific validator**
    
    A validator offers a way to customize and reuse a validation specification.
    If a field is configured with a `{@link #validator}`
    function, it will be passed the current field value.  The `{@link #validator}`
    function is expected to return either:
    
    - Boolean `true`  if the value is valid (validation continues).
    - a String to represent the invalid message if invalid (validation halts).

2. **Basic Validation**

    If the `{@link #validator}` has not halted validation,
    basic validation proceeds as follows:
    
    - `{@link #allowBlank}` : (Invalid message = `{@link #emptyText}`)
    
        Depending on the configuration of <code>{@link #allowBlank}</code>, a
        blank field will cause validation to halt at this step and return
        Boolean true or false accordingly.
    
    - `{@link #minLength}` : (Invalid message = `{@link #minLengthText}`)

        If the passed value does not satisfy the `{@link #minLength}`
        specified, validation halts.

    -  `{@link #maxLength}` : (Invalid message = `{@link #maxLengthText}`)

        If the passed value does not satisfy the `{@link #maxLength}`
        specified, validation halts.

3. **Preconfigured Validation Types (VTypes)**

    If none of the prior validation steps halts validation, a field
    configured with a `{@link #vtype}` will utilize the
    corresponding {@link Ext.form.field.VTypes VTypes} validation function.
    If invalid, either the field's `{@link #vtypeText}` or
    the VTypes vtype Text property will be used for the invalid message.
    Keystrokes on the field will be filtered according to the VTypes
    vtype Mask property.

4. **Field specific regex test**

    If none of the prior validation steps halts validation, a field's
    configured <code>{@link #regex}</code> test will be processed.
    The invalid message for this test is configured with `{@link #regexText}`

     * @param {Mixed} value The value to validate. The processed raw value will be used if nothing is passed

/**
 * @class Ext.form.field.TextArea
 * @extends Ext.form.field.Text

This class creates a multiline text field, which can be used as a direct replacement for traditional 
textarea fields. In addition, it supports automatically {@link #grow growing} the height of the textarea to 
fit its content.

All of the configuration options from {@link Ext.form.field.Text} can be used on TextArea.
{@img Ext.form.TextArea/Ext.form.TextArea.png Ext.form.TextArea component}
Example usage:

    Ext.create('Ext.form.FormPanel', {
        title      : 'Sample TextArea',
        width      : 400,
        bodyPadding: 10,
        renderTo   : Ext.getBody(),
        items: [{
            xtype     : 'textareafield',
            grow      : true,
            name      : 'message',
            fieldLabel: 'Message',
            anchor    : '100%'
        }]
    }); 

Some other useful configuration options when using {@link #grow} are {@link #growMin} and {@link #growMax}. These 
allow you to set the minimum and maximum grow heights for the textarea.

/**
 * @class Ext.window.MessageBox
 * @extends Ext.window.Window

Utility class for generating different styles of message boxes.  The singleton instance, `Ext.Msg` can also be used.
Note that a MessageBox is asynchronous.  Unlike a regular JavaScript `alert` (which will halt
browser execution), showing a MessageBox will not cause the code to stop.  For this reason, if you have code
that should only run *after* some user feedback from the MessageBox, you must use a callback function
(see the `function` parameter for {@link #show} for more details).

{@img Ext.window.MessageBox/messagebox1.png alert MessageBox}
{@img Ext.window.MessageBox/messagebox2.png prompt MessageBox}
{@img Ext.window.MessageBox/messagebox3.png show MessageBox}
#Example usage:#

    // Basic alert:
    Ext.Msg.alert('Status', 'Changes saved successfully.');

    // Prompt for user data and process the result using a callback:
    Ext.Msg.prompt('Name', 'Please enter your name:', function(btn, text){

/**
 * @class Ext.form.Basic
 * @extends Ext.util.Observable

Provides input field management, validation, submission, and form loading services for the collection
of {@link Ext.form.field.Field Field} instances within a {@link Ext.container.Container}. It is recommended
that you use a {@link Ext.form.Panel} as the form container, as that has logic to automatically
hook up an instance of {@link Ext.form.Basic} (plus other conveniences related to field configuration.)

#Form Actions#

The Basic class delegates the handling of form loads and submits to instances of {@link Ext.form.action.Action}.
See the various Action implementations for specific details of each one's functionality, as well as the
documentation for {@link #doAction} which details the configuration options that can be specified in
each action call.

The default submit Action is {@link Ext.form.action.Submit}, which uses an Ajax request to submit the
form's values to a configured URL. To enable normal browser submission of an Ext form, use the
{@link #standardSubmit} config option.

Note: File uploads are not performed using normal 'Ajax' techniques; see the description for
{@link #hasUpload} for details.

#Example usage:#

    Ext.create('Ext.form.Panel', {
        title: 'Basic Form',
        renderTo: Ext.getBody(),
        bodyPadding: 5,
        width: 350,

        // Any configuration items here will be automatically passed along to
        // the Ext.form.Basic instance when it gets created.

        // The form will submit an AJAX request to this URL when submitted
        url: 'save-form.php',

        items: [{
            fieldLabel: 'Field',
            name: 'theField'
        }],

        buttons: [{
            text: 'Submit',
            handler: function() {
                // The getForm() method returns the Ext.form.Basic instance:
                var form = this.up('form').getForm();
                if (form.isValid()) {
                    // Submit the Ajax request and handle the response
                    form.submit({
                        success: function(form, action) {
                           Ext.Msg.alert('Success', action.result.msg);
                        },
                        failure: function(form, action) {
                            Ext.Msg.alert('Failed', action.result.msg);
                        }
                    });
                }
            }
        }]
    });

/**
 * @class Ext.form.FieldAncestor

A mixin for {@link Ext.container.Container} components that are likely to have form fields in their
items subtree. Adds the following capabilities:

- Methods for handling the addition and removal of {@link Ext.form.Labelable} and {@link Ext.form.field.Field}
  instances at any depth within the container.
- Events ({@link #fieldvaliditychange} and {@link #fielderrorchange}) for handling changes to the state
  of individual fields at the container level.
- Automatic application of {@link #fieldDefaults} config properties to each field added within the
  container, to facilitate uniform configuration of all fields.

This mixin is primarily for internal use by {@link Ext.form.Panel} and {@link Ext.form.FieldContainer},
and should not normally need to be used directly.

/**
 * @class Ext.form.FieldContainer
 * @extends Ext.container.Container

FieldContainer is a derivation of {@link Ext.container.Container Container} that implements the
{@link Ext.form.Labelable Labelable} mixin. This allows it to be configured so that it is rendered with
a {@link #fieldLabel field label} and optional {@link #msgTarget error message} around its sub-items.
This is useful for arranging a group of fields or other components within a single item in a form, so
that it lines up nicely with other fields. A common use is for grouping a set of related fields under
a single label in a form.

The container's configured {@link #items} will be layed out within the field body area according to the
configured {@link #layout} type. The default layout is `'autocontainer'`.

Like regular fields, FieldContainer can inherit its decoration configuration from the
{@link Ext.form.Panel#fieldDefaults fieldDefaults} of an enclosing FormPanel. In addition,
FieldContainer itself can pass {@link #fieldDefaults} to any {@link Ext.form.Labelable fields}
it may itself contain.

If you are grouping a set of {@link Ext.form.field.Checkbox Checkbox} or {@link Ext.form.field.Radio Radio}
fields in a single labeled container, consider using a {@link Ext.form.CheckboxGroup}
or {@link Ext.form.RadioGroup} instead as they are specialized for handling those types.

            // The body area will contain three text fields, arranged
            // horizontally, separated by draggable splitters.

/**
 * @class Ext.form.FieldSet
 * @extends Ext.container.Container
 * 
 * A container for grouping sets of fields, rendered as a HTML `fieldset` element. The {@link #title}
 * config will be rendered as the fieldset's `legend`.
 * 
 * While FieldSets commonly contain simple groups of fields, they are general {@link Ext.container.Container Containers}
 * and may therefore contain any type of components in their {@link #items}, including other nested containers.
 * The default {@link #layout} for the FieldSet's items is `'anchor'`, but it can be configured to use any other
 * layout type.
 * 
 * FieldSets may also be collapsed if configured to do so; this can be done in two ways:
 * 
 * 1. Set the {@link #collapsible} config to true; this will result in a collapse button being rendered next to
 *    the {@link #title legend title}, or:
 * 2. Set the {@link #checkboxToggle} config to true; this is similar to using {@link #collapsible} but renders
 *    a {@link Ext.form.field.Checkbox checkbox} in place of the toggle button. The fieldset will be expanded when the
 *    checkbox is checked and collapsed when it is unchecked. The checkbox will also be included in the
 *    {@link Ext.form.Basic#submit form submit parameters} using the {@link #checkboxName} as its parameter name.
 *
 * {@img Ext.form.FieldSet/Ext.form.FieldSet.png Ext.form.FieldSet component}

/**
 * @class Ext.form.Label
 * @extends Ext.Component

Produces a standalone `<label />` element which can be inserted into a form and be associated with a field
in that form using the {@link #forId} property.

**NOTE:** in most cases it will be more appropriate to use the {@link Ext.form.Labelable#fieldLabel fieldLabel}
and associated config properties ({@link Ext.form.Labelable#labelAlign}, {@link Ext.form.Labelable#labelWidth},
etc.) in field components themselves, as that allows labels to be uniformly sized throughout the form.
Ext.form.Label should only be used when your layout can not be achieved with the standard
{@link Ext.form.Labelable field layout}.

You will likely be associating the label with a field component that extends {@link Ext.form.field.Base}, so
you should make sure the {@link #forId} is set to the same value as the {@link Ext.form.field.Base#inputId inputId}
of that field.

The label's text can be set using either the {@link #text} or {@link #html} configuration properties; the
difference between the two is that the former will automatically escape HTML characters when rendering, while
the latter will not.

/**
 * @class Ext.form.Panel
 * @extends Ext.panel.Panel

FormPanel provides a standard container for forms. It is essentially a standard {@link Ext.panel.Panel} which
automatically creates a {@link Ext.form.Basic BasicForm} for managing any {@link Ext.form.field.Field}
objects that are added as descendants of the panel. It also includes conveniences for configuring and
working with the BasicForm and the collection of Fields.

__Layout__

By default, FormPanel is configured with `{@link Ext.layout.container.Anchor layout:'anchor'}` for
the layout of its immediate child items. This can be changed to any of the supported container layouts.
The layout of sub-containers is configured in {@link Ext.container.Container#layout the standard way}.

__BasicForm__

Although **not listed** as configuration options of FormPanel, the FormPanel class accepts all
of the config options supported by the {@link Ext.form.Basic} class, and will pass them along to
the internal BasicForm when it is created.

**Note**: If subclassing FormPanel, any configuration options for the BasicForm must be applied to
the `initialConfig` property of the FormPanel. Applying {@link Ext.form.Basic BasicForm}
configuration settings to `this` will *not* affect the BasicForm's configuration.

The following events fired by the BasicForm will be re-fired by the FormPanel and can therefore be
listened for on the FormPanel itself:

- {@link Ext.form.Basic#beforeaction beforeaction}
- {@link Ext.form.Basic#actionfailed actionfailed}
- {@link Ext.form.Basic#actioncomplete actioncomplete}
- {@link Ext.form.Basic#validitychange validitychange}
- {@link Ext.form.Basic#dirtychange dirtychange}

__Field Defaults__

The {@link #fieldDefaults} config option conveniently allows centralized configuration of default values
for all fields added as descendants of the FormPanel. Any config option recognized by implementations
of {@link Ext.form.Labelable} may be included in this object. See the {@link #fieldDefaults} documentation
for details of how the defaults are applied.

__Form Validation__

With the default configuration, form fields are validated on-the-fly while the user edits their values.
This can be controlled on a per-field basis (or via the {@link #fieldDefaults} config) with the field
config properties {@link Ext.form.field.Field#validateOnChange} and {@link Ext.form.field.Base#checkChangeEvents},
and the FormPanel's config properties {@link #pollForChanges} and {@link #pollInterval}.

Any component within the FormPanel can be configured with `formBind: true`. This will cause that
component to be automatically disabled when the form is invalid, and enabled when it is valid. This is most
commonly used for Button components to prevent submitting the form in an invalid state, but can be used on
any component type.

For more information on form validation see the following:

- {@link Ext.form.field.Field#validateOnChange}
- {@link #pollForChanges} and {@link #pollInterval}
- {@link Ext.form.field.VTypes}
- {@link Ext.form.Basic#doAction BasicForm.doAction clientValidation notes}

__Form Submission__

By default, Ext Forms are submitted through Ajax, using {@link Ext.form.action.Action}. See the documentation for
{@link Ext.form.Basic} for details.

        submit: Profile.updateBasicInfo
    },
    // specify the order for the passed params
    paramOrder: ['uid', 'foo']
});
 * </code></pre>
 * The data packet sent to the server will resemble something like:
 * <pre><code>
{
    "action":"Profile","method":"updateBasicInfo","type":"rpc","tid":"6",
    "result":{
        "success":true,
        "id":{

            "name":"Aaron Conran","email":"aaron@sencha.com","company":"Sencha Inc."
        }
    }
}
 * </code></pre>
 * The form will process a data packet returned by the server that is similar
 * to the following:
 * <pre><code>
// sample success packet (batched requests)
[
    {
        "action":"Profile","method":"updateBasicInfo","type":"rpc","tid":3,

/**
 * @class Ext.form.field.Checkbox
 * @extends Ext.form.field.Base

Single checkbox field. Can be used as a direct replacement for traditional checkbox fields. Also serves as a
parent class for {@link Ext.form.field.Radio radio buttons}.

__Labeling:__ In addition to the {@link Ext.form.Labelable standard field labeling options}, checkboxes
may be given an optional {@link #boxLabel} which will be displayed immediately after checkbox. Also see
{@link Ext.form.CheckboxGroup} for a convenient method of grouping related checkboxes.

__Values:__
The main value of a checkbox is a boolean, indicating whether or not the checkbox is checked.
The following values will check the checkbox:
* `true`
* `'true'`
* `'1'`
* `'on'`

Any other value will uncheck the checkbox.

In addition to the main boolean value, you may also specify a separate {@link #inputValue}. This will be
sent as the parameter value when the form is {@link Ext.form.Basic#submit submitted}. You will want to set
this value if you have multiple checkboxes with the same {@link #name}. If not specified, the value `on`
will be used.

 * @class Ext.view.View
 * @extends Ext.view.AbstractView
 *
 * A mechanism for displaying data using custom layout templates and formatting. DataView uses an {@link Ext.XTemplate}
 * as its internal templating mechanism, and is bound to an {@link Ext.data.Store}
 * so that as the data in the store changes the view is automatically updated to reflect the changes.  The view also
 * provides built-in behavior for many common events that can occur for its contained items including click, doubleclick,
 * mouseover, mouseout, etc. as well as a built-in selection model. <b>In order to use these features, an {@link #itemSelector}
 * config must be provided for the DataView to determine what nodes it will be working with.</b>

/**
 * @class Ext.form.field.Number
 * @extends Ext.form.field.Spinner

A numeric text field that provides automatic keystroke filtering to disallow non-numeric characters,
and numeric validation to limit the value to a range of valid numbers. The range of acceptable number
values can be controlled by setting the {@link #minValue} and {@link #maxValue} configs, and fractional
decimals can be disallowed by setting {@link #allowDecimals} to `false`.

By default, the number field is also rendered with a set of up/down spinner buttons and has
up/down arrow key and mouse wheel event listeners attached for incrementing/decrementing the value by the
{@link #step} value. To hide the spinner buttons set `{@link #hideTrigger hideTrigger}:true`; to disable the arrow key
and mouse wheel handlers set `{@link #keyNavEnabled keyNavEnabled}:false` and
`{@link #mouseWheelEnabled mouseWheelEnabled}:false`. See the example below.

/**
 * @class Ext.toolbar.Paging
 * @extends Ext.toolbar.Toolbar
 * <p>As the amount of records increases, the time required for the browser to render
 * them increases. Paging is used to reduce the amount of data exchanged with the client.
 * Note: if there are more records/rows than can be viewed in the available screen area, vertical
 * scrollbars will be added.</p>
 * <p>Paging is typically handled on the server side (see exception below). The client sends
 * parameters to the server side, which the server needs to interpret and then respond with the
 * appropriate data.</p>
 * <p><b>Ext.toolbar.Paging</b> is a specialized toolbar that is bound to a {@link Ext.data.Store}
 * and provides automatic paging control. This Component {@link Ext.data.Store#load load}s blocks
 * of data into the <tt>{@link #store}</tt> by passing {@link Ext.data.Store#paramNames paramNames} used for
 * paging criteria.</p>
 *
 * {@img Ext.toolbar.Paging/Ext.toolbar.Paging.png Ext.toolbar.Paging component}
 *
 * <p>PagingToolbar is typically used as one of the Grid's toolbars:</p>
 * <pre><code>
 *    var itemsPerPage = 2;   // set the number of items you want per page
 *    
 *    var store = Ext.create('Ext.data.Store', {
 *        id:'simpsonsStore',
 *        autoLoad: false,
 *        fields:['name', 'email', 'phone'],
 *        pageSize: itemsPerPage, // items per page
 *        proxy: {
 *            type: 'ajax',
 *            url: 'pagingstore.js',  // url that will load data with respect to start and limit params
 *            reader: {
 *                type: 'json',
 *                root: 'items',
 *                totalProperty: 'total'
 *            }
 *        }
 *    });
 *    
 *    // specify segment of data you want to load using params
 *    store.load({
 *        params:{
 *            start:0,    
 *            limit: itemsPerPage
 *        }
 *    });
 *    
 *    Ext.create('Ext.grid.Panel', {
 *        title: 'Simpsons',
 *        store: store,
 *        columns: [
 *            {header: 'Name',  dataIndex: 'name'},
 *            {header: 'Email', dataIndex: 'email', flex:1},
 *            {header: 'Phone', dataIndex: 'phone'}
 *        ],
 *        width: 400,
 *        height: 125,
 *        dockedItems: [{
 *            xtype: 'pagingtoolbar',
 *            store: store,   // same store GridPanel is using
 *            dock: 'bottom',
 *            displayInfo: true
 *        }],
 *        renderTo: Ext.getBody()
 *    });
 * </code></pre>
 *
 * <p>To use paging, pass the paging requirements to the server when the store is first loaded.</p>
 * <pre><code>
store.load({
    params: {
        // specify params for the first page load if using paging
        start: 0,          
        limit: myPageSize,
        // other params
        foo:   'bar'
    }
});
 * </code></pre>
 * 
 * <p>If using {@link Ext.data.Store#autoLoad store's autoLoad} configuration:</p>
 * <pre><code>
var myStore = new Ext.data.Store({
    {@link Ext.data.Store#autoLoad autoLoad}: {start: 0, limit: 25},
    ...
});
 * </code></pre>
 * 
 * <p>The packet sent back from the server would have this form:</p>
 * <pre><code>
{
    "success": true,
    "results": 2000, 
    "rows": [ // <b>*Note:</b> this must be an Array 
        { "id":  1, "name": "Bill", "occupation": "Gardener" },

        ...
        { "id": 25, "name":  "Sue", "occupation": "Botanist" }
    ]
}
 * </code></pre>
 * <p><u>Paging with Local Data</u></p>
 * <p>Paging can also be accomplished with local data using extensions:</p>

/**
 * @class Ext.form.field.ComboBox
 * @extends Ext.form.field.Picker
 *
 * A combobox control with support for autocomplete, remote loading, and many other features.
 *
 * A ComboBox is like a combination of a traditional HTML text `&lt;input&gt;` field and a `&lt;select&gt;`
 * field; the user is able to type freely into the field, and/or pick values from a dropdown selection
 * list. The user can input any value by default, even if it does not appear in the selection list;
 * to prevent free-form values and restrict them to items in the list, set {@link #forceSelection} to `true`.
 *
 * The selection list's options are populated from any {@link Ext.data.Store}, including remote
 * stores. The data items in the store are mapped to each option's displayed text and backing value via
 * the {@link #valueField} and {@link #displayField} configurations, respectively.
 *
 * If your store is not remote, i.e. it depends only on local data and is loaded up front, you should be
 * sure to set the {@link #queryMode} to `'local'`, as this will improve responsiveness for the user.
 *
 * {@img Ext.form.ComboBox/Ext.form.ComboBox.png Ext.form.ComboBox component}
 *
 * ## Example usage:
 *
 *     // The data store containing the list of states
 *     var states = Ext.create('Ext.data.Store', {
 *         fields: ['abbr', 'name'],
 *         data : [
 *             {"abbr":"AL", "name":"Alabama"},
 *             {"abbr":"AK", "name":"Alaska"},
 *             {"abbr":"AZ", "name":"Arizona"}
 *             //...
 *         ]
 *     });
 *
 *     // Create the combo box, attached to the states data store
 *     Ext.create('Ext.form.ComboBox', {
 *         fieldLabel: 'Choose State',
 *         store: states,
 *         queryMode: 'local',
 *         displayField: 'name',
 *         valueField: 'abbr',
 *         renderTo: Ext.getBody()
 *     });
 *
 * ## Events
 *
 * To do something when something in ComboBox is selected, configure the select event:
 *
 *     var cb = Ext.create('Ext.form.ComboBox', {
 *         // all of your config options
 *         listeners:{
 *              scope: yourScope,
 *              'select': yourFunction
 *         }
 *     });
 *
 *     // Alternatively, you can assign events after the object is created:
 *     var cb = new Ext.form.field.ComboBox(yourOptions);
 *     cb.on('select', yourFunction, yourScope);
 *
 * ## Multiple Selection
 *
 * ComboBox also allows selection of multiple items from the list; to enable multi-selection set the
 * {@link #multiSelect} config to `true`.
 *
 * @constructor
 * Create a new ComboBox.
 * @param {Object} config Configuration options
 * @xtype combo

/**
 * @class Ext.form.field.Date
 * @extends Ext.form.field.Picker

Provides a date input field with a {@link Ext.picker.Date date picker} dropdown and automatic date
validation.

This field recognizes and uses the JavaScript Date object as its main {@link #value} type. In addition,
it recognizes string values which are parsed according to the {@link #format} and/or {@link #altFormats}
configs. These may be reconfigured to use date formats appropriate for the user's locale.

The field may be limited to a certain range of dates by using the {@link #minValue}, {@link #maxValue},
{@link #disabledDays}, and {@link #disabledDates} config parameters. These configurations will be used both
in the field's validation, and in the date picker dropdown by preventing invalid dates from being selected.
{@img Ext.form.Date/Ext.form.Date.png Ext.form.Date component}
#Example usage:#

    Ext.create('Ext.form.Panel', {
        width: 300,
        bodyPadding: 10,
        title: 'Dates',
        items: [{
            xtype: 'datefield',
            anchor: '100%',
            fieldLabel: 'From',
            name: 'from_date',
            maxValue: new Date()  // limited to the current date or prior
        }, {
            xtype: 'datefield',
            anchor: '100%',
            fieldLabel: 'To',
            name: 'to_date',
            value: new Date()  // defaults to today
        }],
            renderTo: Ext.getBody()
    });

#Date Formats Examples#

This example shows a couple of different date format parsing scenarios. Both use custom date format
configurations; the first one matches the configured `format` while the second matches the `altFormats`.

    Ext.create('Ext.form.Panel', {
        renderTo: Ext.getBody(),

            xtype: 'datefield',
            anchor: '100%',
            fieldLabel: 'Date',
            name: 'date',
            // The value matches the format; will be parsed and displayed using that format.
            format: 'm d Y',
            value: '2 4 1978'
        }, {
            xtype: 'datefield',
            anchor: '100%',
            fieldLabel: 'Date',
            name: 'date',
            // The value does not match the format, but does match an altFormat; will be parsed
            // using the altFormat and displayed using the format.

/**
 * @class Ext.form.field.File
 * @extends Ext.form.field.Text

A file upload field which has custom styling and allows control over the button text and other
features of {@link Ext.form.field.Text text fields} like {@link Ext.form.field.Text#emptyText empty text}.
It uses a hidden file input element behind the scenes to allow user selection of a file and to
perform the actual upload during {@link Ext.form.Basic#submit form submit}.

Because there is no secure cross-browser way to programmatically set the value of a file input,
the standard Field `setValue` method is not implemented. The `{@link #getValue}` method will return
a value that is browser-dependent; some have just the file name, some have a full path, some use
a fake path.

/**
 * @class Ext.form.field.Radio
 * @extends Ext.form.field.Checkbox

Single radio field. Similar to checkbox, but automatically handles making sure only one radio is checked
at a time within a group of radios with the same name.

__Labeling:__
In addition to the {@link Ext.form.Labelable standard field labeling options}, radio buttons
may be given an optional {@link #boxLabel} which will be displayed immediately to the right of the input. Also
see {@link Ext.form.RadioGroup} for a convenient method of grouping related radio buttons.

__Values:__
The main value of a Radio field is a boolean, indicating whether or not the radio is checked.

The following values will check the radio:
* `true`
* `'true'`
* `'1'`
* `'on'`

Any other value will uncheck it.

In addition to the main boolean value, you may also specify a separate {@link #inputValue}. This will be sent
as the parameter value when the form is {@link Ext.form.Basic#submit submitted}. You will want to set this
value if you have multiple radio buttons with the same {@link #name}, as is almost always the case.

/**
 * @class Ext.grid.View
 * @extends Ext.view.Table

The grid View class provides extra {@link Ext.grid.Panel} specific functionality to the
{@link Ext.view.Table}. In general, this class is not instanced directly, instead a viewConfig
option is passed to the grid:

    Ext.create('Ext.grid.Panel', {
        // other options
        viewConfig: {
            stripeRows: false
        }
    });
    
__Drag Drop__
Drag and drop functionality can be achieved in the grid by attaching a {@link Ext.grid.plugin.DragDrop} plugin
when creating the view.

    Ext.create('Ext.grid.Panel', {
        // other options
        viewConfig: {
            plugins: {
                ddGroup: 'people-group',
                ptype: 'gridviewdragdrop',

 * @class Ext.grid.Panel
 * @extends Ext.panel.Table
 *
 * Grids are an excellent way of showing large amounts of tabular data on the client side. Essentially a supercharged 
 * `<table>`, GridPanel makes it easy to fetch, sort and filter large amounts of data.
 * 
 * Grids are composed of 2 main pieces - a {@link Ext.data.Store Store} full of data and a set of columns to render.
 *
 * {@img Ext.grid.Panel/Ext.grid.Panel1.png Ext.grid.Panel component}
 *
 * ## Basic GridPanel
 *
 *     Ext.create('Ext.data.Store', {
 *         storeId:'simpsonsStore',
 *         fields:['name', 'email', 'phone'],
 *         data:{'items':[
 *             {"name":"Lisa", "email":"lisa@simpsons.com", "phone":"555-111-1224"},
 *             {"name":"Bart", "email":"bart@simpsons.com", "phone":"555--222-1234"},
 *             {"name":"Homer", "email":"home@simpsons.com", "phone":"555-222-1244"},                        
 *             {"name":"Marge", "email":"marge@simpsons.com", "phone":"555-222-1254"}            
 *         ]},
 *         proxy: {
 *             type: 'memory',
 *             reader: {
 *                 type: 'json',
 *                 root: 'items'
 *             }
 *         }
 *     });
 *     
 *     Ext.create('Ext.grid.Panel', {
 *         title: 'Simpsons',
 *         store: Ext.data.StoreManager.lookup('simpsonsStore'),
 *         columns: [
 *             {header: 'Name',  dataIndex: 'name'},
 *             {header: 'Email', dataIndex: 'email', flex:1},
 *             {header: 'Phone', dataIndex: 'phone'}
 *         ],
 *         height: 200,
 *         width: 400,
 *         renderTo: Ext.getBody()
 *     });
 * 
 * The code above produces a simple grid with three columns. We specified a Store which will load JSON data inline. 
 * In most apps we would be placing the grid inside another container and wouldn't need to use the
 * {@link #height}, {@link #width} and {@link #renderTo} configurations but they are included here to make it easy to get
 * up and running.
 * 
 * The grid we created above will contain a header bar with a title ('Simpsons'), a row of column headers directly underneath
 * and finally the grid rows under the headers.
 * 
 * ## Configuring columns
 * 
 * By default, each column is sortable and will toggle between ASC and DESC sorting when you click on its header. Each
 * column header is also reorderable by default, and each gains a drop-down menu with options to hide and show columns.
 * It's easy to configure each column - here we use the same example as above and just modify the columns config:
 * 
 *     columns: [
 *         {
 *             header: 'Name',
 *             dataIndex: 'name',
 *             sortable: false,
 *             hideable: false,
 *             flex: 1
 *         },
 *         {
 *             header: 'Email',
 *             dataIndex: 'email',
 *             hidden: true
 *         },
 *         {
 *             header: 'Phone',
 *             dataIndex: 'phone',
 *             width: 100
 *         }
 *     ]
 * 
 * We turned off sorting and hiding on the 'Name' column so clicking its header now has no effect. We also made the Email
 * column hidden by default (it can be shown again by using the menu on any other column). We also set the Phone column to
 * a fixed with of 100px and flexed the Name column, which means it takes up all remaining width after the other columns 
 * have been accounted for. See the {@link Ext.grid.column.Column column docs} for more details.
 * 
 * ## Renderers
 * 
 * As well as customizing columns, it's easy to alter the rendering of individual cells using renderers. A renderer is 
 * tied to a particular column and is passed the value that would be rendered into each cell in that column. For example,
 * we could define a renderer function for the email column to turn each email address into a mailto link:
 * 
 *     columns: [
 *         {
 *             header: 'Email',
 *             dataIndex: 'email',
 *             renderer: function(value) {
 *                 return Ext.String.format('<a href="mailto:{0}">{1}</a>', value, value);
 *             }
 *         }
 *     ]
 * 
 * See the {@link Ext.grid.column.Column column docs} for more information on renderers.
 * 
 * ## Selection Models
 * 
 * Sometimes all you want is to render data onto the screen for viewing, but usually it's necessary to interact with or 
 * update that data. Grids use a concept called a Selection Model, which is simply a mechanism for selecting some part of
 * the data in the grid. The two main types of Selection Model are RowSelectionModel, where entire rows are selected, and
 * CellSelectionModel, where individual cells are selected.
 * 
 * Grids use a Row Selection Model by default, but this is easy to customise like so:
 * 
 *     Ext.create('Ext.grid.Panel', {
 *         selType: 'cellmodel',
 *         store: ...
 *     });
 * 
 * Specifying the `cellmodel` changes a couple of things. Firstly, clicking on a cell now
 * selects just that cell (using a {@link Ext.selection.RowModel rowmodel} will select the entire row), and secondly the
 * keyboard navigation will walk from cell to cell instead of row to row. Cell-based selection models are usually used in
 * conjunction with editing.
 * 
 * {@img Ext.grid.Panel/Ext.grid.Panel2.png Ext.grid.Panel cell editing}
 *
 * ## Editing
 * 
 * Grid has built-in support for in-line editing. There are two chief editing modes - cell editing and row editing. Cell
 * editing is easy to add to your existing column setup - here we'll just modify the example above to include an editor
 * on both the name and the email columns:
 * 
 *     Ext.create('Ext.grid.Panel', {
 *         title: 'Simpsons',
 *         store: Ext.data.StoreManager.lookup('simpsonsStore'),
 *         columns: [
 *             {header: 'Name',  dataIndex: 'name', field: 'textfield'},
 *             {header: 'Email', dataIndex: 'email', flex:1, 
 *                 field:{
 *                     xtype:'textfield',
 *                     allowBlank:false
 *                 }
 *             },
 *             {header: 'Phone', dataIndex: 'phone'}
 *         ],
 *         selType: 'cellmodel',
 *         plugins: [
 *             Ext.create('Ext.grid.plugin.CellEditing', {
 *                 clicksToEdit: 1
 *             })
 *         ],
 *         height: 200,
 *         width: 400,
 *         renderTo: Ext.getBody()
 *     });
 * 
 * This requires a little explanation. We're passing in {@link #store store} and {@link #columns columns} as normal, but 
 * this time we've also specified a {@link #field field} on two of our columns. For the Name column we just want a default
 * textfield to edit the value, so we specify 'textfield'. For the Email column we customized the editor slightly by 
 * passing allowBlank: false, which will provide inline validation.
 * 
 * To support cell editing, we also specified that the grid should use the 'cellmodel' {@link #selType}, and created an
 * instance of the {@link Ext.grid.plugin.CellEditing CellEditing plugin}, which we configured to activate each editor after a
 * single click.
 * 
 * {@img Ext.grid.Panel/Ext.grid.Panel3.png Ext.grid.Panel row editing}
 *
 * ## Row Editing
 * 
 * The other type of editing is row-based editing, using the RowEditor component. This enables you to edit an entire row
 * at a time, rather than editing cell by cell. Row Editing works in exactly the same way as cell editing, all we need to
 * do is change the plugin type to {@link Ext.grid.plugin.RowEditing}, and set the selType to 'rowmodel':
 * 
 *     Ext.create('Ext.grid.Panel', {
 *         title: 'Simpsons',
 *         store: Ext.data.StoreManager.lookup('simpsonsStore'),
 *         columns: [
 *             {header: 'Name',  dataIndex: 'name', field: 'textfield'},
 *             {header: 'Email', dataIndex: 'email', flex:1, 
 *                 field:{
 *                     xtype:'textfield',
 *                     allowBlank:false
 *                 }
 *             },
 *             {header: 'Phone', dataIndex: 'phone'}
 *         ],
 *         selType: 'rowmodel',
 *         plugins: [
 *             Ext.create('Ext.grid.plugin.RowEditing', {
 *                 clicksToEdit: 1
 *             })
 *         ],
 *         height: 200,
 *         width: 400,
 *         renderTo: Ext.getBody()
 *     });
 * 
 * Again we passed some configuration to our {@link Ext.grid.plugin.RowEditing} plugin, and now when we click each row a row
 * editor will appear and enable us to edit each of the columns we have specified an editor for.
 * 
 * ## Sorting & Filtering
 * 
 * Every grid is attached to a {@link Ext.data.Store Store}, which provides multi-sort and filtering capabilities. It's
 * easy to set up a grid to be sorted from the start:
 * 
 *     var myGrid = Ext.create('Ext.grid.Panel', {
 *         store: {
 *             fields: ['name', 'email', 'phone'],
 *             sorters: ['name', 'phone']
 *         },
 *         columns: [
 *             {text: 'Name',  dataIndex: 'name'},
 *             {text: 'Email', dataIndex: 'email'}
 *         ]
 *     });
 * 
 * Sorting at run time is easily accomplished by simply clicking each column header. If you need to perform sorting on 
 * more than one field at run time it's easy to do so by adding new sorters to the store:
 * 
 *     myGrid.store.sort([
 *         {property: 'name',  direction: 'ASC'},
 *         {property: 'email', direction: 'DESC'},
 *     ]);
 * 
 * {@img Ext.grid.Panel/Ext.grid.Panel4.png Ext.grid.Panel grouping}
 * 
 * ## Grouping
 * 
 * Grid supports the grouping of rows by any field. For example if we had a set of employee records, we might want to 
 * group by the department that each employee works in. Here's how we might set that up:
 * 
 *     var store = Ext.create('Ext.data.Store', {
 *         storeId:'employeeStore',
 *         fields:['name', 'senority', 'department'],
 *         groupField: 'department',
 *         data:{'employees':[
 *             {"name":"Michael Scott", "senority":7, "department":"Manangement"},
 *             {"name":"Dwight Schrute", "senority":2, "department":"Sales"},
 *             {"name":"Jim Halpert", "senority":3, "department":"Sales"},
 *             {"name":"Kevin Malone", "senority":4, "department":"Accounting"},
 *             {"name":"Angela Martin", "senority":5, "department":"Accounting"}                        
 *         ]},
 *         proxy: {
 *             type: 'memory',
 *             reader: {
 *                 type: 'json',
 *                 root: 'employees'
 *             }
 *         }
 *     });
 *     
 *     Ext.create('Ext.grid.Panel', {
 *         title: 'Employees',
 *         store: Ext.data.StoreManager.lookup('employeeStore'),
 *         columns: [
 *             {header: 'Name',  dataIndex: 'name'},
 *             {header: 'Senority', dataIndex: 'senority'}
 *         ],        
 *         features: [{ftype:'grouping'}],
 *         width: 200,
 *         height: 275,
 *         renderTo: Ext.getBody()
 *     });
 * 
 * ## Infinite Scrolling
 *
 * Grid supports infinite scrolling as an alternative to using a paging toolbar. Your users can scroll through thousands
 * of records without the performance penalties of renderering all the records on screen at once. The grid should be bound
 * to a store with a pageSize specified.
 *
 *     var grid = Ext.create('Ext.grid.Panel', {
 *         // Use a PagingGridScroller (this is interchangeable with a PagingToolbar)
 *         verticalScrollerType: 'paginggridscroller',
 *         // do not reset the scrollbar when the view refreshs
 *         invalidateScrollerOnRefresh: false,
 *         // infinite scrolling does not support selection
 *         disableSelection: true,
 *         // ...
 *     });
 * 
 * ## Paging
 *
 * Grid supports paging through large sets of data via a PagingToolbar or PagingGridScroller (see the Infinite Scrolling section above).
 * To leverage paging via a toolbar or scroller, you need to set a pageSize configuration on the Store.
 *
 *     var itemsPerPage = 2;   // set the number of items you want per page
 *     
 *     var store = Ext.create('Ext.data.Store', {
 *         id:'simpsonsStore',
 *         autoLoad: false,
 *         fields:['name', 'email', 'phone'],
 *         pageSize: itemsPerPage, // items per page
 *         proxy: {
 *             type: 'ajax',
 *             url: 'pagingstore.js',  // url that will load data with respect to start and limit params
 *             reader: {
 *                 type: 'json',
 *                 root: 'items',
 *                 totalProperty: 'total'
 *             }
 *         }
 *     });
 *     
 *     // specify segment of data you want to load using params
 *     store.load({
 *         params:{
 *             start:0,    
 *             limit: itemsPerPage
 *         }
 *     });
 *     
 *     Ext.create('Ext.grid.Panel', {
 *         title: 'Simpsons',
 *         store: store,
 *         columns: [
 *             {header: 'Name',  dataIndex: 'name'},

 *             {header: 'Phone', dataIndex: 'phone'}

/**
 * @class Ext.grid.column.Column
 * @extends Ext.grid.header.Container
 * 
 * This class specifies the definition for a column inside a {@link Ext.grid.Panel}. It encompasses
 * both the grid header configuration as well as displaying data within the grid itself. If the
 * {@link #columns} configuration is specified, this column will become a column group and can
 * container other columns inside. In general, this class will not be created directly, rather
 * an array of column configurations will be passed to the grid:
 * 
 * {@img Ext.grid.column.Column/Ext.grid.column.Column.png Ext.grid.column.Column grid column}
 *
 * ## Code
 *    Ext.create('Ext.data.Store', {
 *        storeId:'employeeStore',
 *        fields:['firstname', 'lastname', 'senority', 'dep', 'hired'],
 *        data:[
 *            {firstname:"Michael", lastname:"Scott", senority:7, dep:"Manangement", hired:"01/10/2004"},
 *            {firstname:"Dwight", lastname:"Schrute", senority:2, dep:"Sales", hired:"04/01/2004"},
 *            {firstname:"Jim", lastname:"Halpert", senority:3, dep:"Sales", hired:"02/22/2006"},
 *            {firstname:"Kevin", lastname:"Malone", senority:4, dep:"Accounting", hired:"06/10/2007"},
 *            {firstname:"Angela", lastname:"Martin", senority:5, dep:"Accounting", hired:"10/21/2008"}                        
 *        ]
 *    });
 *    
 *    Ext.create('Ext.grid.Panel', {
 *        title: 'Column Demo',
 *        store: Ext.data.StoreManager.lookup('employeeStore'),
 *        columns: [
 *            {text: 'First Name',  dataIndex:'firstname'},
 *            {text: 'Last Name',  dataIndex:'lastname'},
 *            {text: 'Hired Month',  dataIndex:'hired', xtype:'datecolumn', format:'M'},              
 *            {text: 'Deparment (Yrs)', xtype:'templatecolumn', tpl:'{dep} ({senority})'}
 *        ],
 *        width: 400,
 *        renderTo: Ext.getBody()
 *    });
 *     
 * ## Convenience Subclasses
 * There are several column subclasses that provide default rendering for various data types
 *
 *  - {@link Ext.grid.column.Action}: Renders icons that can respond to click events inline
 *  - {@link Ext.grid.column.Boolean}: Renders for boolean values 
 *  - {@link Ext.grid.column.Date}: Renders for date values
 *  - {@link Ext.grid.column.Number}: Renders for numeric values
 *  - {@link Ext.grid.column.Template}: Renders a value using an {@link Ext.XTemplate} using the record data 
 * 
 * ## Setting Sizes
 * The columns are laid out by a {@link Ext.layout.container.HBox} layout, so a column can either
 * be given an explicit width value or a flex configuration. If no width is specified the grid will
 * automatically the size the column to 100px. For column groups, the size is calculated by measuring
 * the width of the child columns, so a width option should not be specified in that case.
 * 
 * ## Header Options
 *  - {@link #text}: Sets the header text for the column
 *  - {@link #sortable}: Specifies whether the column can be sorted by clicking the header or using the column menu
 *  - {@link #hideable}: Specifies whether the column can be hidden using the column menu
 *  - {@link #menuDisabled}: Disables the column header menu
 *  - {@link #draggable}: Specifies whether the column header can be reordered by dragging
 *  - {@link #groupable}: Specifies whether the grid can be grouped by the column dataIndex. See also {@link Ext.grid.feature.Grouping}
 * 
 * ## Data Options
 *  - {@link #dataIndex}: The dataIndex is the field in the underlying {@link Ext.data.Store} to use as the value for the column.
 *  - {@link #renderer}: Allows the underlying store value to be transformed before being displayed in the grid
 * 
 * @xtype gridcolumn

 * grid creation cycle. This class provides the base template methods that are available to the developer,

 *  - {@link Ext.grid.feature.Grouping} - Shows grid rows in groups as specified by the {@link Ext.data.Store}
 *  - {@link Ext.grid.feature.RowBody} - Adds a body section for each grid row that can contain markup.
 *  - {@link Ext.grid.feature.Summary} - Adds a summary row at the bottom of the grid with aggregate totals for a column.
 *

 * ## Menu Augmentation
 * This feature adds extra options to the grid column menu to provide the user with functionality to modify the grouping.
 * This can be disabled by setting the {@link #enableGroupingMenu} option. The option to disallow grouping from being turned off
 * by thew user is {@link #enableNoGroups}.
 * 
 * ## Controlling Group Text
 * The {@link #groupHeaderTpl} is used to control the rendered title for each group. It can modified to customized
 * the default display.
 * 
 * ## Example Usage
 * 
 *     var groupingFeature = Ext.create('Ext.grid.feature.Grouping', {
 *         groupHeaderTpl: 'Group: {name} ({rows.length})', //print the number of items in the group
 *         startCollapsed: true // start all groups collapsed
 *     });

/**
 * @class Ext.grid.feature.GroupingSummary
 * @extends Ext.grid.feature.Grouping
 * 
 * This feature adds an aggregate summary row at the bottom of each group that is provided
 * by the {@link Ext.grid.feature.Grouping} feature. There are 2 aspects to the summary:
 * 
 * ## Calculation
 * 
 * The summary value needs to be calculated for each column in the grid. This is controlled
 * by the summaryType option specified on the column. There are several built in summary types,
 * which can be specified as a string on the column configuration. These call underlying methods
 * on the store:
 *
 *  - {@link Ext.data.Store#count count}
 *  - {@link Ext.data.Store#sum sum}
 *  - {@link Ext.data.Store#min min}
 *  - {@link Ext.data.Store#max max}
 *  - {@link Ext.data.Store#average average}
 *
 * Alternatively, the summaryType can be a function definition. If this is the case,
 * the function is called with an array of records to calculate the summary value.
 * 
 * ## Rendering
 * 
 * Similar to a column, the summary also supports a summaryRenderer function. This
 * summaryRenderer is called before displaying a value. The function is optional, if
 * not specified the default calculated value is shown. The summaryRenderer is called with:
 *
 *  - value {Object} - The calculated value.
 *  - data {Object} - Contains all raw summary values for the row.
 *  - field {String} - The name of the field we are calculating
 * 
 * ## Example Usage
 *
 *     Ext.define('TestResult', {
 *         extend: 'Ext.data.Model',
 *         fields: ['student', 'subject', {
 *             name: 'mark',
 *             type: 'int'
 *         }]
 *     });
 *     
 *     Ext.create('Ext.grid.Panel', {
 *         width: 200,
 *         height: 240,
 *         renderTo: document.body,
 *         features: [{
 *             groupHeaderTpl: 'Subject: {name}',
 *             ftype: 'groupingsummary'
 *         }],
 *         store: {
 *             model: 'TestResult',
 *             groupField: 'subject',
 *             data: [{
 *                 student: 'Student 1',
 *                 subject: 'Math',
 *                 mark: 84

/**
 * @class Ext.grid.feature.Summary
 * @extends Ext.grid.feature.AbstractSummary
 * 
 * This feature is used to place a summary row at the bottom of the grid. If using a grouping, 
 * see {@link Ext.grid.feature.GroupingSummary}. There are 2 aspects to calculating the summaries, 
 * calculation and rendering.
 * 
 * ## Calculation
 * The summary value needs to be calculated for each column in the grid. This is controlled
 * by the summaryType option specified on the column. There are several built in summary types,
 * which can be specified as a string on the column configuration. These call underlying methods
 * on the store:
 *
 *  - {@link Ext.data.Store#count count}
 *  - {@link Ext.data.Store#sum sum}
 *  - {@link Ext.data.Store#min min}
 *  - {@link Ext.data.Store#max max}
 *  - {@link Ext.data.Store#average average}
 *
 * Alternatively, the summaryType can be a function definition. If this is the case,
 * the function is called with an array of records to calculate the summary value.
 * 
 * ## Rendering
 * Similar to a column, the summary also supports a summaryRenderer function. This
 * summaryRenderer is called before displaying a value. The function is optional, if
 * not specified the default calculated value is shown. The summaryRenderer is called with:
 *
 *  - value {Object} - The calculated value.
 *  - data {Object} - Contains all raw summary values for the row.
 *  - field {String} - The name of the field we are calculating
 * 
 * ## Example Usage
 *
 *     Ext.define('TestResult', {
 *         extend: 'Ext.data.Model',
 *         fields: ['student', {
 *             name: 'mark',

/**
 * @class Ext.grid.plugin.CellEditing
 * @extends Ext.grid.plugin.Editing
 *
 * The Ext.grid.plugin.CellEditing plugin injects editing at a cell level for a Grid. Only a single
 * cell will be editable at a time. The field that will be used for the editor is defined at the
 * {@link Ext.grid.column.Column#field field}. The editor can be a field instance or a field configuration.
 *
 * If an editor is not specified for a particular column then that cell will not be editable and it will
 * be skipped when activated via the mouse or the keyboard.
 *
 * The editor may be shared for each column in the grid, or a different one may be specified for each column.
 * An appropriate field type should be chosen to match the data structure that it will be editing. For example,
 * to edit a date, it would be useful to specify {@link Ext.form.field.Date} as the editor.
 *
 * {@img Ext.grid.plugin.CellEditing/Ext.grid.plugin.CellEditing.png Ext.grid.plugin.CellEditing plugin}

/**
 * @class Ext.grid.plugin.RowEditing
 * @extends Ext.grid.plugin.Editing
 * 
 * The Ext.grid.plugin.RowEditing plugin injects editing at a row level for a Grid. When editing begins,
 * a small floating dialog will be shown for the appropriate row. Each editable column will show a field
 * for editing. There is a button to save or cancel all changes for the edit.
 * 
 * The field that will be used for the editor is defined at the
 * {@link Ext.grid.column.Column#field field}. The editor can be a field instance or a field configuration.
 * If an editor is not specified for a particular column then that column won't be editable and the value of
 * the column will be displayed.
 * The editor may be shared for each column in the grid, or a different one may be specified for each column.
 * An appropriate field type should be chosen to match the data structure that it will be editing. For example,
 * to edit a date, it would be useful to specify {@link Ext.form.field.Date} as the editor.

/**
 * @class Ext.layout.container.Card
 * @extends Ext.layout.container.AbstractCard
  * <p>This layout manages multiple child Components, each fitted to the Container, where only a single child Component can be
  * visible at any given time.  This layout style is most commonly used for wizards, tab implementations, etc.
  * This class is intended to be extended or created via the layout:'card' {@link Ext.container.Container#layout} config,
  * and should generally not need to be created directly via the new keyword.</p>
  * <p>The CardLayout's focal method is {@link #setActiveItem}.  Since only one panel is displayed at a time,
  * the only way to move from one Component to the next is by calling setActiveItem, passing the id or index of
  * the next panel to display.  The layout itself does not provide a user interface for handling this navigation,
  * so that functionality must be provided by the developer.</p>
  * <p>In the following example, a simplistic wizard setup is demonstrated.  A button bar is added
  * to the footer of the containing panel to provide navigation buttons.  The buttons will be handled by a
  * common navigation routine -- for this example, the implementation of that routine has been ommitted since
  * it can be any type of custom logic.  Note that other uses of a CardLayout (like a tab control) would require a
  * completely different implementation.  For serious implementations, a better approach would be to extend
  * CardLayout to provide the custom functionality needed.  
  * {@img Ext.layout.container.Card/Ext.layout.container.Card.png Ext.layout.container.Card container layout}

         // branching logic that might be required, handle alternate actions like cancellation
         // or finalization, etc.  A complete wizard implementation could get pretty
         // sophisticated depending on the complexity required, and should probably be
         // done as a subclass of CardLayout in a real-world implementation.

/**
 * @class Ext.layout.container.Column
 * @extends Ext.layout.container.Auto
 * <p>This is the layout style of choice for creating structural layouts in a multi-column format where the width of
 * each column can be specified as a percentage or fixed width, but the height is allowed to vary based on the content.
 * This class is intended to be extended or created via the layout:'column' {@link Ext.container.Container#layout} config,
 * and should generally not need to be created directly via the new keyword.</p>
 * <p>ColumnLayout does not have any direct config options (other than inherited ones), but it does support a
 * specific config property of <b><tt>columnWidth</tt></b> that can be included in the config of any panel added to it.  The
 * layout will use the columnWidth (if present) or width of each panel during layout to determine how to size each panel.
 * If width or columnWidth is not specified for a given panel, its width will default to the panel's width (or auto).</p>
 * <p>The width property is always evaluated as pixels, and must be a number greater than or equal to 1.
 * The columnWidth property is always evaluated as a percentage, and must be a decimal value greater than 0 and
 * less than 1 (e.g., .25).</p>
 * <p>The basic rules for specifying column widths are pretty simple.  The logic makes two passes through the
 * set of contained panels.  During the first layout pass, all panels that either have a fixed width or none
 * specified (auto) are skipped, but their widths are subtracted from the overall container width.  During the second
 * pass, all panels with columnWidths are assigned pixel widths in proportion to their percentages based on
 * the total <b>remaining</b> container width.  In other words, percentage width panels are designed to fill the space
 * left over by all the fixed-width and/or auto-width panels.  Because of this, while you can specify any number of columns
 * with different percentages, the columnWidths must always add up to 1 (or 100%) when added together, otherwise your
 * layout may not render as expected.

/**
 * @class Ext.layout.container.Table
 * @extends Ext.layout.container.Auto
 * <p>This layout allows you to easily render content into an HTML table.  The total number of columns can be
 * specified, and rowspan and colspan can be used to create complex layouts within the table.
 * This class is intended to be extended or created via the <code>layout: {type: 'table'}</code>
 * {@link Ext.container.Container#layout} config, and should generally not need to be created directly via the new keyword.</p>
 * <p>Note that when creating a layout via config, the layout-specific config properties must be passed in via
 * the {@link Ext.container.Container#layout} object which will then be applied internally to the layout.  In the
 * case of TableLayout, the only valid layout config properties are {@link #columns} and {@link #tableAttrs}.
 * However, the items added to a TableLayout can supply the following table-specific config properties:</p>
 * <ul>
 * <li><b>rowspan</b> Applied to the table cell containing the item.</li>
 * <li><b>colspan</b> Applied to the table cell containing the item.</li>
 * <li><b>cellId</b> An id applied to the table cell containing the item.</li>
 * <li><b>cellCls</b> A CSS class name added to the table cell containing the item.</li>
 * </ul>
 * <p>The basic concept of building up a TableLayout is conceptually very similar to building up a standard
 * HTML table.  You simply add each panel (or "cell") that you want to include along with any span attributes
 * specified as the special config properties of rowspan and colspan which work exactly like their HTML counterparts.
 * Rather than explicitly creating and nesting rows and columns as you would in HTML, you simply specify the
 * total column count in the layoutConfig and start adding panels in their natural order from left to right,
 * top to bottom.  The layout will automatically figure out, based on the column count, rowspans and colspans,
 * how to position each panel within the table.  Just like with HTML tables, your rowspans and colspans must add
 * up correctly in your overall layout or you'll end up with missing and/or extra cells!  Example usage:</p>
 * {@img Ext.layout.container.Table/Ext.layout.container.Table.png Ext.layout.container.Table container layout}

/**
 * @class Ext.menu.Menu
 * @extends Ext.panel.Panel
 *
 * A menu object. This is the container to which you may add {@link Ext.menu.Item menu items}.
 *
 * Menus may contain either {@link Ext.menu.Item menu items}, or general {@link Ext.Component Components}.
 * Menus may also contain {@link Ext.panel.AbstractPanel#dockedItems docked items} because it extends {@link Ext.panel.Panel}.
 *
 * To make a contained general {@link Ext.Component Component} line up with other {@link Ext.menu.Item menu items},
 * specify `{@link Ext.menu.Item#iconCls iconCls}: 'no-icon'` _or_ `{@link Ext.menu.Item#indent indent}: true`.
 * This reserves a space for an icon, and indents the Component in line with the other menu items.
 * See {@link Ext.form.field.ComboBox}.{@link Ext.form.field.ComboBox#getListParent getListParent} for an example.

 * By default, Menus are absolutely positioned, floating Components. By configuring a Menu with `{@link #floating}:false`,
 * a Menu may be used as a child of a {@link Ext.container.Container Container}.

/**

 * @class Ext.tab.Panel
 * @extends Ext.panel.Panel

A basic tab container. TabPanels can be used exactly like a standard {@link Ext.panel.Panel} for layout purposes, but also 
have special support for containing child Components (`{@link Ext.container.Container#items items}`) that are managed 
using a {@link Ext.layout.container.Card CardLayout layout manager}, and displayed as separate tabs.

__Note:__

By default, a tab's close tool _destroys_ the child tab Component and all its descendants. This makes the child tab 
Component, and all its descendants __unusable__. To enable re-use of a tab, configure the TabPanel with `{@link #autoDestroy autoDestroy: false}`.

__TabPanel's layout:__

TabPanels use a Dock layout to position the {@link Ext.tab.Bar TabBar} at the top of the widget. Panels added to the TabPanel will have their 
header hidden by default because the Tab will automatically take the Panel's configured title and icon.

TabPanels use their {@link Ext.panel.Panel#header header} or {@link Ext.panel.Panel#footer footer} element (depending on the {@link #tabPosition} 
configuration) to accommodate the tab selector buttons. This means that a TabPanel will not display any configured title, and will not display any 
configured header {@link Ext.panel.Panel#tools tools}.

To display a header, embed the TabPanel in a {@link Ext.panel.Panel Panel} which uses `{@link Ext.container.Container#layout layout:'fit'}`.

__Examples:__

Here is a basic TabPanel rendered to the body. This also shows the useful configuration {@link #activeTab}, which allows you to set the active tab on render. 
If you do not set an {@link #activeTab}, no tabs will be active by default.
{@img Ext.tab.Panel/Ext.tab.Panel1.png TabPanel component}
Example usage:

    Ext.create('Ext.tab.Panel', {
        width: 300,
        height: 200,
        activeTab: 0,
        items: [
            {
                title: 'Tab 1',
                bodyPadding: 10,
                html : 'A simple tab'
            },
            {
                title: 'Tab 2',
                html : 'Another one'
            }
        ],
        renderTo : Ext.getBody()
    }); 
    
It is easy to control the visibility of items in the tab bar. Specify hidden: true to have the
tab button hidden initially. Items can be subsequently hidden and show by accessing the
tab property on the child item.

Example usage:
    
    var tabs = Ext.create('Ext.tab.Panel', {
        width: 400,
        height: 400,
        renderTo: document.body,
        items: [{
            title: 'Home',
            html: 'Home',
            itemId: 'home'
        }, {
            title: 'Users',
            html: 'Users',
            itemId: 'users',
            hidden: true
        }, {
            title: 'Tickets',
            html: 'Tickets',
            itemId: 'tickets'
        }]    
    });
    
    setTimeout(function(){
        tabs.child('#home').tab.hide();
        var users = tabs.child('#users');
        users.tab.show();
        tabs.setActiveTab(users);
    }, 1000);

You can remove the background of the TabBar by setting the {@link #plain} property to `false`.

Example usage:

    Ext.create('Ext.tab.Panel', {
        width: 300,
        height: 200,
        activeTab: 0,
        plain: true,
        items: [
            {
                title: 'Tab 1',
                bodyPadding: 10,
                html : 'A simple tab'
            },
            {
                title: 'Tab 2',
                html : 'Another one'
            }
        ],
        renderTo : Ext.getBody()
    }); 

Another useful configuration of TabPanel is {@link #tabPosition}. This allows you to change the position where the tabs are displayed. The available 
options for this are `'top'` (default) and `'bottom'`.
{@img Ext.tab.Panel/Ext.tab.Panel2.png TabPanel component}
Example usage:

    Ext.create('Ext.tab.Panel', {
        width: 300,
        height: 200,
        activeTab: 0,
        bodyPadding: 10,        
        tabPosition: 'bottom',
        items: [
            {
                title: 'Tab 1',
                html : 'A simple tab'
            },
            {
                title: 'Tab 2',
                html : 'Another one'
            }
        ],
        renderTo : Ext.getBody()
    }); 

The {@link #setActiveTab} is a very useful method in TabPanel which will allow you to change the current active tab. You can either give it an index or 
an instance of a tab.

Example usage:

    var tabs = Ext.create('Ext.tab.Panel', {
        items: [
            {
                id   : 'my-tab',
                title: 'Tab 1',
                html : 'A simple tab'
            },
            {
                title: 'Tab 2',
                html : 'Another one'
            }
        ],
        renderTo : Ext.getBody()
    });
    
    var tab = Ext.getCmp('my-tab');
    
    Ext.create('Ext.button.Button', {
        renderTo: Ext.getBody(),
        text    : 'Select the first tab',
        scope   : this,
        handler : function() {
            tabs.setActiveTab(tab);
        }
    });
    
    Ext.create('Ext.button.Button', {
        text    : 'Select the second tab',
        scope   : this,
        handler : function() {
            tabs.setActiveTab(1);
        },
        renderTo : Ext.getBody()        
    });

The {@link #getActiveTab} is a another useful method in TabPanel which will return the current active tab.

Example usage:

    var tabs = Ext.create('Ext.tab.Panel', {
        items: [
            {
                title: 'Tab 1',
                html : 'A simple tab'
            },
            {
                title: 'Tab 2',
                html : 'Another one'
            }
        ],
        renderTo : Ext.getBody()        
    });
    
    Ext.create('Ext.button.Button', {
        text    : 'Get active tab',
        scope   : this,
        handler : function() {
            var tab = tabs.getActiveTab();
            alert('Current tab: ' + tab.title);
        },
        renderTo : Ext.getBody()        
    });

Adding a new tab is very simple with a TabPanel. You simple call the {@link #add} method with an config object for a panel.

Example usage:

    var tabs = Ext.Create('Ext.tab.Panel', {
        items: [
            {
                title: 'Tab 1',
                html : 'A simple tab'
            },
            {
                title: 'Tab 2',
                html : 'Another one'
            }
        ],
        renderTo : Ext.getBody()        
    });
    
    Ext.create('Ext.button.Button', {
        text    : 'New tab',
        scope   : this,
        handler : function() {
            var tab = tabs.add({
                title: 'Tab ' + (tabs.items.length + 1), //we use the tabs.items property to get the length of current items/tabs
                html : 'Another one'
            });
            
            tabs.setActiveTab(tab);
        },
        renderTo : Ext.getBody()
    });

Additionally, removing a tab is very also simple with a TabPanel. You simple call the {@link #remove} method with an config object for a panel.

Example usage:

    var tabs = Ext.Create('Ext.tab.Panel', {        
        items: [
            {
                title: 'Tab 1',
                html : 'A simple tab'
            },
            {
                id   : 'remove-this-tab',
                title: 'Tab 2',
                html : 'Another one'
            }
        ],
        renderTo : Ext.getBody()
    });
    
    Ext.Create('Ext.button.Button', {
        text    : 'Remove tab',
        scope   : this,
        handler : function() {
            var tab = Ext.getCmp('remove-this-tab');
            tabs.remove(tab);
        },
        renderTo : Ext.getBody()
    });
