A tag name or DomHelper spec used to create the Element which will +encapsulate this Component.

+ + +

You do not normally need to specify this. For the base classes Ext.Component and Ext.container.Container, +this defaults to 'div'. The more complex Sencha classes use a more complex +DOM structure specified by their own renderTpls.

+ + +

This is intended to allow the developer to create application-specific utility Components encapsulated by +different DOM elements. Example usage:

+ + +
{
+    xtype: 'component',
+    autoEl: {
+        tag: 'img',
+        src: 'http://www.example.com/example.jpg'
+    }
+}, {
+    xtype: 'component',
+    autoEl: {
+        tag: 'blockquote',
+        html: 'autoEl is cool!'
+    }
+}, {
+    xtype: 'container',
+    autoEl: 'ul',
+    cls: 'ux-unordered-list',
+    items: {
+        xtype: 'component',

The sizing and positioning of a Component's internal Elements is the responsibility of +the Component's layout manager which sizes a Component's internal structure in response to the Component being sized.

+ + +

Generally, developers will not use this configuration as all provided Components which need their internal +elements sizing (Such as input fields) come with their own componentLayout managers.

+ + +

The default layout manager will be used on instances of the base Ext.Component class +which simply sizes the Component's encapsulating element to the height and width specified in the setSize method.

    +
  • Description : +
    This config option is used to take an existing HTML element and place it in the layout element +of a new component (it simply moves the specified DOM element after the Component is rendered to use as the content.
  • +
  • Notes : +
    The specified HTML element is appended to the layout element of the component after any configured +HTML has been inserted, and so the document will not contain this element at the time the render event is fired.
    +
    The specified HTML element used will not participate in any layout +scheme that the Component may use. It is just HTML. Layouts operate on child items.

An HTML fragment, or a DomHelper specification to use as the layout element +content (defaults to ''). The HTML content is added after the component is rendered, +so the document will not contain this HTML at the time the render event is fired. +This content is inserted into the body before any configured contentEl is appended.

+

The unique id of this component instance (defaults to an auto-assigned id).

+ + +

It should not be necessary to use this configuration except for singleton objects in your application. +Components created with an id may be accessed globally using Ext.getCmp.

+ + +

Instead of using assigned ids, use the itemId config, and ComponentQuery which +provides selector-based searching for Sencha Components analogous to DOM querying. The Container +class contains shortcut methods to query its descendant Components by selector.

+ + +

Note that this id will also be used as the element id for the containing HTML element +that is rendered to the page for this component. This allows you to write id-based CSS +rules to style the specific instance of this component uniquely, and also to select +sub-elements using this component's id as the parent.

+ + +

Note: to avoid complications imposed by a unique id also see itemId.

+ + +

Note: to access the container of a Component see ownerCt.

+ +
 
An itemId can be used as an alternative way to get a reference to a component +when no object reference is available. ...

An itemId can be used as an alternative way to get a reference to a component +when no object reference is available. Instead of using an id with +Ext.getCmp, use itemId with +Ext.container.Container.getComponent which will retrieve +itemId's or id's. Since itemId's are an index to the +container's internal MixedCollection, the itemId is scoped locally to the container -- +avoiding potential conflicts with Ext.ComponentManager which requires a unique +id.

+ + +
var c = new Ext.panel.Panel({ //
+    height: 300,
+    renderTo: document.body,
+    layout: 'auto',
+    items: [
+        {
+            itemId: 'p1',
+            title: 'Panel 1',
+            height: 150
+        },
+        {
+            itemId: 'p2',
+            title: 'Panel 2',
+            height: 150
+        }
+    ]
+})
+p1 = c.getComponent('p1'); // not the same as Ext.getCmp()
+p2 = p1.ownerCt.getComponent('p2'); // reference via a sibling
+
+ + +

Also see id, query, down and child.

+ + +

Note: to access the container of an item see ownerCt.

(optional)

A config object containing one or more event handlers to be added to this +object during initialization. This should be a valid listeners config object as specified in the +addListener example for attaching multiple handlers at once.

+ +

DOM events from ExtJs Components

+ + +

While some ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this + + +

is usually only done when extra value can be added. For example the DataView's +click event passing the node clicked on. To access DOM +events directly from a child element of a Component, we need to specify the element option to +identify the Component property to add a DOM listener to:

+ +
new Ext.panel.Panel({
+    width: 400,
+    height: 200,
+    dockedItems: [{
+        xtype: 'toolbar'
+    }],
+    listeners: {
+        click: {
+            element: 'el', //bind to the underlying el property on the panel
+            fn: function(){ console.log('click el'); }
+        },
+        dblclick: {
+            element: 'body', //bind to the underlying body property on the panel
+            fn: function(){ console.log('dblclick body'); }
+        }
+    }
+});

An object or array of objects that will provide custom functionality for this component. The only +requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.Component. +When a component is created, if any plugins are available, the component will call the init method on each +plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the +component as needed to provide its functionality.

+

An object containing properties specifying DomQuery selectors which identify child elements +created by the render process.

+ +

After the Component's internal structure is rendered according to the renderTpl, this object is iterated through, +and the found Elements are added as properties to the Component using the renderSelector property name.

+ +

For example, a Component which rendered an image, and description into its element might use the following properties +coded into its prototype:

+ +
renderTpl: '<img src="{imageUrl}" class="x-image-component-img"><div class="x-image-component-desc">{description}>/div<',
+
+renderSelectors: {
+    image: 'img.x-image-component-img',
+    descEl: 'div.x-image-component-desc'
+}
+
+ +

After rendering, the Component would have a property image referencing its child img Element, +and a property descEl referencing the div Element which contains the description.

+

  • Notes :
      +
      Do not use this option if the Component is to be a child item of +a Container. It is the responsibility of the +Container's layout manager +to render and manage its child items.
      +
      When using this config, a call to render() is not required.

An XTemplate used to create the internal structure inside this Component's +encapsulating Element.

+ + +

You do not normally need to specify this. For the base classes Ext.Component +and Ext.container.Container, this defaults to null which means that they will be initially rendered +with no internal structure; they render their Element empty. The more specialized ExtJS and Touch classes +which use a more complex DOM structure, provide their own template definitions.

+ + +

This is intended to allow the developer to create application-specific utility Components with customized +internal structure.

+ + +

Upon rendering, any created child elements may be automatically imported into object properties using the +renderSelectors option.

The unique id for this object to use for state management purposes.

+ +

See stateful for an explanation of saving and restoring state.

+ +
 
A flag which causes the object to attempt to restore the state of +internal properties from a saved state on startup. ...

A flag which causes the object to attempt to restore the state of +internal properties from a saved state on startup. The object must have +a stateId 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 object.

+

For state saving to work, the state manager's provider must have been +set to an implementation of Ext.state.Provider which overrides the +set and get +methods to save and recall name/value pairs. A built-in implementation, +Ext.state.CookieProvider is available.

+

To set the state provider for the current page:

+
Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
+    expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now
+}));
+
+

A stateful object attempts to save state when one of the events +listed in the stateEvents configuration fires.

+

To save state, a stateful object first serializes its state by +calling getState. By default, this function does +nothing. The developer must provide an implementation which returns an +object hash which represents the restorable state of the object.

+

The value yielded by getState is passed to Ext.state.Manager.set +which uses the configured Ext.state.Provider to save the object +keyed by the stateId

. +

During construction, a stateful object attempts to restore +its state by calling Ext.state.Manager.get passing the +stateId

+

The resulting object is passed to applyState. +The default implementation of applyState simply copies +properties into the object, but a developer may override this to support +more behaviour.

+

You can perform extra processing on state save and restore by attaching +handlers to the beforestaterestore, staterestore, +beforestatesave and statesave events.

    The name of the event to listen for. May also be an object who's property names are event names. See

    +
  • handler : Function

    The method the event invokes.

    +
  • scope : Object

    (optional) The scope (this reference) in which the handler function is executed. +If omitted, defaults to the object which fired the event.

    +
  • options : Object

    (optional) An object containing handler configuration. +properties. This may contain any of the following properties:

      +
    • scope : Object
      The scope (this reference) in which the handler function is executed. +If omitted, defaults to the object which fired the event.
    • +
    • delay : Number
      The number of milliseconds to delay the invocation of the handler after the event fires.
    • +
    • single : Boolean
      True to add a handler to handle just the next firing of the event, and then remove itself.
    • +
    • buffer : Number
      Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed +by the specified number of milliseconds. If the event fires again within that time, the original +handler is not invoked, but the new handler is scheduled in its place.
    • +
    • target : Observable
      Only call the handler if the event was fired on the target Observable, not +if the event was bubbled up from a child Observable.
    • +
    • element : String
      This option is only valid for listeners bound to Components. +The name of a Component property which references an element to add a listener to.

      + +

      This option is useful during Component construction to add DOM event listeners to elements of Components which +will exist only after the Component is rendered. For example, to add a click listener to a Panel's body: +

      new Ext.panel.Panel({
      +    title: 'The title',
      +    listeners: {
      +        click: this.handlePanelClick,
      +        element: 'body'
      +    }
      +});
      +

      + + +

      When added in this way, the options available are the options applicable to Ext.core.Element.addListener

      + + +

    • +

    + +

    +Combining Options
    +Using the options argument, it is possible to combine different types of listeners:
    +
    +A delayed, one-time listener. +

    myPanel.on('hide', this.handleClick, this, {
    +single: true,
    +delay: 100
    +});
    +

    +Attaching multiple handlers in 1 call
    +The method also allows for a single argument to be passed which is a config object containing properties +which specify multiple events. For example: +

    myGridPanel.on({
    +    cellClick: this.onCellClick,
    +    mouseover: this.onMouseOver,
    +    mouseout: this.onMouseOut,
    +    scope: this // Important. Ensure "this" is correct during handler execution
    +});
    +
    . +

    + +

Returns

  • void    +

Perform custom animation on this object.

+

This method is applicable to both the the Component class and the Element class. +It performs animated transitions of certain properties of this object over a specified timeline.

+

The sole parameter is an object which specifies start property values, end property values, and properties which +describe the timeline. Of the properties listed below, only to is mandatory.

+

Properties include

    +
  • from
    An object which specifies start values for the properties being animated. +If not supplied, properties are animated from current settings. The actual properties which may be animated depend upon +ths object being animated. See the sections below on Element and Component animation.
  • +
  • to
    An object which specifies end values for the properties being animated.
  • +
  • duration
    The duration in milliseconds for which the animation will run.
  • +
  • easing
    A string value describing an easing type to modify the rate of change from the default linear to non-linear. Values may be one of:
      +
    • ease
    • +
    • easeIn
    • +
    • easeOut
    • +
    • easeInOut
    • +
    • backIn
    • +
    • backOut
    • +
    • elasticIn
    • +
    • elasticOut
    • +
    • bounceIn
    • +
    • bounceOut
    • +
  • +
  • keyframes
    This is an object which describes the state of animated properties at certain points along the timeline. +it is an object containing properties who's names are the percentage along the timeline being described and who's values specify the animation state at that point.
  • +
  • listeners
    This is a standard listeners configuration object which may be used +to inject behaviour at either the beforeanimate event or the afteranimate event.
  • +

+

Animating an Element

+When animating an Element, the following properties may be specified in from, to, and keyframe objects:
    +
  • x
    The page X position in pixels.
  • +
  • y
    The page Y position in pixels
  • +
  • left
    The element's CSS left value. Units must be supplied.
  • +
  • top
    The element's CSS top value. Units must be supplied.
  • +
  • width
    The element's CSS width value. Units must be supplied.
  • +
  • height
    The element's CSS height value. Units must be supplied.
  • +
  • scrollLeft
    The element's scrollLeft value.
  • +
  • scrollTop
    The element's scrollLeft value.
  • +
  • opacity
    The element's opacity value. This must be a value between 0 and 1.
  • +
+

Be aware than animating an Element which is being used by an Ext Component without in some way informing the Component about the changed element state +will result in incorrect Component behaviour. This is because the Component will be using the old state of the element. To avoid this problem, it is now possible to +directly animate certain properties of Components.

+

Animating a Component

+When animating an Element, the following properties may be specified in from, to, and keyframe objects:
    +
  • x
    The Component's page X position in pixels.
  • +
  • y
    The Component's page Y position in pixels
  • +
  • left
    The Component's left value in pixels.
  • +
  • top
    The Component's top value in pixels.
  • +
  • width
    The Component's width value in pixels.
  • +
  • width
    The Component's width value in pixels.
  • +
  • dynamic
    Specify as true to update the Component's layout (if it is a Container) at every frame +of the animation. Use sparingly as laying out on every intermediate size change is an expensive operation.
  • +
+

For example, to animate a Window to a new size, ensuring that its internal layout, and any shadow is correct:

+
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,
+        }
+    });
+});
+
+

For performance reasons, by default, the internal layout is only updated when the Window reaches its final "to" size. If dynamic updating of the Window's child +Components is required, then configure the animation with dynamic: true and the two child items will maintain their proportions during the animation.

+ +

Parameters

  • config : Object

    An object containing properties which describe the animation's start and end states, and the timeline of the animation.

Enables events fired by this Observable to bubble up an owner hierarchy by calling +this.getBubbleTarget() if present....

Enables events fired by this Observable to bubble up an owner hierarchy by calling +this.getBubbleTarget() if present. There is no implementation in the Observable base class.

+ + +

This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default +implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to +access the required target more quickly.

+ + +

Example:

+ + +
Ext.override(Ext.form.field.Base, {
+//  Add functionality to Field's initComponent to enable the change event to bubble
+initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
+    this.enableBubble('change');
+}),
+
+//  We know that we want Field's events to bubble directly to the FormPanel.
+getBubbleTarget : function() {
+    if (!this.formPanel) {
+        this.formPanel = this.findParentByType('form');
+    }
+    return this.formPanel;
+}
+});
+
+var myForm = new Ext.formPanel({
+title: 'User Details',
+items: [{
+    ...
+}],
+listeners: {
+    change: function() {
+        // Title goes red if form has been modified.
+        myForm.header.setStyle('color', 'red');
+    }
+}
+});
+
+ +
