it the perfect building block for application-oriented user interfaces.</p>
<p>Panels are, by virtue of their inheritance from <a href="output/Ext.Container.html" ext:cls="Ext.Container">Ext.Container</a>, capable
of being configured with a <a href="output/Ext.Container.html#Ext.Container-layout" ext:member="layout" ext:cls="Ext.Container">layout</a>, and containing child Components.</p>
<p>When either specifying child <a href="output/Ext.Component.html#Ext.Component-items" ext:member="items" ext:cls="Ext.Component">items</a> of a Panel, or dynamically <a href="output/Ext.Container.html#Ext.Container-add" ext:member="add" ext:cls="Ext.Container">adding</a> 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's built-in <tt><b><a href="output/Ext.Container.html#Ext.Container-layout" ext:member="layout" ext:cls="Ext.Container">layout</a></b></tt> schemes. By
default, Panels use the <a href="output/Ext.layout.ContainerLayout.html" ext:cls="Ext.layout.ContainerLayout">ContainerLayout</a> 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>
<p>A Panel may also contain <a href="output/Ext.Panel.html#Ext.Panel-bbar" ext:member="bbar" ext:cls="Ext.Panel">bottom</a> and <a href="output/Ext.Panel.html#Ext.Panel-tbar" ext:member="tbar" ext:cls="Ext.Panel">top</a> toolbars, along with separate
<a href="output/Ext.Panel.html#Ext.Panel-header" ext:member="header" ext:cls="Ext.Panel">header</a>, <a href="output/Ext.Panel.html#Ext.Panel-footer" ext:member="footer" ext:cls="Ext.Panel">footer</a> and <a href="output/Ext.Panel.html#Ext.Panel-body" ext:member="body" ext:cls="Ext.Panel">body</a> sections (see <a href="output/Ext.Panel.html#Ext.Panel-frame" ext:member="frame" ext:cls="Ext.Panel">frame</a> for additional
information).</p>
<p>Panel also provides built-in <a href="output/Ext.Panel.html#Ext.Panel-collapsible" ext:member="collapsible" ext:cls="Ext.Panel">expandable and collapsible behavior</a>, along with
a variety of <a href="output/Ext.Panel.html#Ext.Panel-tools" ext:member="tools" ext:cls="Ext.Panel">prebuilt tool buttons</a> that can be wired up to provide other customized
behavior.  Panels can be easily dropped into any <a href="output/Ext.Container.html" ext:cls="Ext.Container">Container</a> or layout, and the
layout and rendering pipeline is <a href="output/Ext.Container.html#Ext.Container-add" ext:member="add" ext:cls="Ext.Container">completely managed by the framework</a>.</p></div><div class="hr"></div><a id="Ext.Panel-configs"></a><h2>Config Options</h2><table cellspacing="0" class="member-table"><tbody><tr><th colspan="2" class="sig-header">Config Options</th><th class="msource-header">Defined By</th></tr><tr class="config-row expandable inherited"><td class="micon"><a href="#expand" class="exi">&nbsp;</a></td><td class="sig"><a id="Ext.Container-activeItem"></a><b><a href="source/Container.html#cfg-Ext.Container-activeItem">activeItem</a></b> : String/Number<div class="mdesc"><div class="short">A string component id or the numeric index of the component that should be initially activated within the

<p><b>Note</b>: Although many components  inherit this config option, not all will
function as expected with a width of 'auto'. Setting autoWidth:true means that the
browser will manage width based on the element's contents, and that Ext will not manage it at all.</p>
<p>If the <i>browser</i> is managing the width, be aware that resizes performed by the browser in response
to changes within the structure of the Component cannot be detected. Therefore changes to the width might
result in elements needing to be synchronized with the new width. For example, where the target element is:</p><pre><code>&lt;div id=<em>'grid-container'</em> style=<em>'margin-left:25%;width:50%'</em>>&lt;/div></code></pre>
A Panel rendered into that target element must listen for browser window resize in order to relay its
child items when the browser changes its width:<pre><code><b>var</b> myPanel = <b>new</b> Ext.Panel({

    monitorResize: true, <i>// relay on browser resize</i>

The Panel's <tt><a href="output/Ext.Panel.html#Ext.Panel-buttonAlign" ext:member="buttonAlign" ext:cls="Ext.Panel">buttonAlign</a></tt> configuration affects the layout of these items, for example:
<pre><code><b>var</b> w = <b>new</b> Ext.Window({
    height: 250,
    width: 500,
    bbar: <b>new</b> Ext.Toolbar({
        items: [{
            text: <em>'bbar Left'</em>
        },<em>'->'</em>,{

        }]
    }),
    <a href="output/Ext.Panel.html#Ext.Panel-buttonAlign" ext:member="buttonAlign" ext:cls="Ext.Panel">buttonAlign</a>: <em>'left'</em>, <i>// anything but <em>'center'</em> or <em>'right'</em> and you can use <em>"-"</em>, and <em>"->"</em></i>

    fbar: [{

    },<em>'->'</em>,{

    }]
}).show();</code></pre>
<p><b>Note:</b> Although a Toolbar may contain Field components, these will <b>not<b> be updated by a load
of an ancestor FormPanel. A Panel's toolbars are not part of the standard Container->Component hierarchy, and
so are not scanned to collect form items. However, the values <b>will</b> be submitted because form

<br><p>The sizing and positioning of child <a href="output/items.html" ext:cls="items">items</a> is the responsibility of

for state to be managed. Auto-generated ids are not guaranteed to be stable
across page loads and cannot be relied upon to save and restore the same
state for a component.<p>
<p>For state saving to work, the state manager's provider must have been
set to an implementation of <a href="output/Ext.state.Provider.html" ext:cls="Ext.state.Provider">Ext.state.Provider</a> which overrides the
<a href="output/Ext.state.Provider.html#Ext.state.Provider-set" ext:member="set" ext:cls="Ext.state.Provider">set</a> and <a href="output/Ext.state.Provider.html#Ext.state.Provider-get" ext:member="get" ext:cls="Ext.state.Provider">get</a>
methods to save and recall name/value pairs. A built-in implementation,
<a href="output/Ext.state.CookieProvider.html" ext:cls="Ext.state.CookieProvider">Ext.state.CookieProvider</a> is available.</p>
<p>To set the state provider for the current page:</p>
<pre><code>Ext.state.Manager.setProvider(<b>new</b> Ext.state.CookieProvider({
    expires: <b>new</b> Date(<b>new</b> Date().getTime()+(1000*60*60*24*7)), <i>//7 days from now</i>
}));</code></pre>
<p>A stateful Component attempts to save state when one of the events
listed in the <code><a href="output/Ext.Component.html#Ext.Component-stateEvents" ext:member="stateEvents" ext:cls="Ext.Component">stateEvents</a></code> configuration fires.</p>
<p>To save state, a stateful Component first serializes its state by
calling <b><code>getState</code></b>. By default, this function does
nothing. The developer must provide an implementation which returns an
object hash which represents the Component's restorable state.</p>
<p>The value yielded by getState is passed to <a href="output/Ext.state.Manager.html#Ext.state.Manager-set" ext:member="set" ext:cls="Ext.state.Manager">Ext.state.Manager.set</a>
which uses the configured <a href="output/Ext.state.Provider.html" ext:cls="Ext.state.Provider">Ext.state.Provider</a> to save the object
keyed by the Component's <code><a href="output/stateId.html" ext:cls="stateId">stateId</a></code>, or, if that is not
specified, its <code><a href="output/Ext.Component.html#Ext.Component-id" ext:member="id" ext:cls="Ext.Component">id</a></code>.</p>
<p>During construction, a stateful Component attempts to <i>restore</i>
its state by calling <a href="output/Ext.state.Manager.html#Ext.state.Manager-get" ext:member="get" ext:cls="Ext.state.Manager">Ext.state.Manager.get</a> passing the
<code><a href="output/Ext.Component.html#Ext.Component-stateId" ext:member="stateId" ext:cls="Ext.Component">stateId</a></code>, or, if that is not specified, the
<code><a href="output/Ext.Component.html#Ext.Component-id" ext:member="id" ext:cls="Ext.Component">id</a></code>.</p>
<p>The resulting object is passed to <b><code>applyState</code></b>.
The default implementation of <code>applyState</code> simply copies
properties into the object, but a developer may override this to support
more behaviour.</p>
<p>You can perform extra processing on state save and restore by attaching
handlers to the <a href="output/Ext.Component.html#Ext.Component-beforestaterestore" ext:member="beforestaterestore" ext:cls="Ext.Component">beforestaterestore</a>, <a href="output/Ext.Component.html#Ext.Component-staterestore" ext:member="staterestore" ext:cls="Ext.Component">staterestore</a>,

<p>This may may be overridden to provide a custom DOM structure for tools based upon a more

visual indication when hovering over the tool:</p><pre><code><b>var</b> win = <b>new</b> Ext.Window({

<p>Note that the CSS class "x-tool-pdf" should have an associated style rule which provides an

<p>Note that, apart from the toggle tool which is provided when a panel is collapsible, these
tools only provide the visual button. Any required functionality must be provided by adding
handlers that implement the necessary behavior.</p>
<p>Example usage:</p>
<pre><code>tools:[{
    id:<em>'refresh'</em>,
    qtip: <em>'Refresh form Data'</em>,
    <i>// hidden:true,</i>
    handler: <b>function</b>(event, toolEl, panel){
        <i>// refresh logic</i>
    }
},
{
    id:<em>'help'</em>,
    qtip: <em>'Get Help'</em>,
    handler: <b>function</b>(event, toolEl, panel){
        <i>// whatever</i>
    }
}]</code></pre>
<p>For the custom id of <tt>'help'</tt> define two relevant css classes with a link to
a 15x15 image:</p>
<pre><code>.x-tool-help {background-image: url(images/help.png);}

    single: true,

<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>
<pre><code>myGridPanel.on({
