Get the reference to the current class from which this object was instantiated. Unlike statics, this.self is scope-dependent and it's meant to be used for dynamic inheritance. See statics for a detailed comparison

Ext.define('My.Cat', {
    statics: {
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        alert(this.self.speciesName); / dependent on 'this'

        return this;
    },

    clone: function() {
        return new this.self();
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',
    statics: {
        speciesName: 'Snow Leopard'         // My.SnowLeopard.speciesName = 'Snow Leopard'
    }
});

var cat = new My.Cat();                     // alerts 'Cat'
var snowLeopard = new My.SnowLeopard();     // alerts 'Snow Leopard'

var clone = snowLeopard.clone();
alert(Ext.getClassName(clone));             // alerts 'My.SnowLeopard'

Available since: 4.0.0

Adds the specified events to the list of events which this Observable may fire.

Available since: 1.1.0

Parameters

• o : Object/String

  Either an object with event names as properties with a value of true or the first event name string if multiple event names are being passed as separate parameters. Usage:

  this.addEvents({
      storeloaded: true,
      storecleared: true
  });
  

• more : String... (optional)

  Additional event names if multiple event names are being passed as separate parameters. Usage:

  this.addEvents('storeloaded', 'storecleared');
  

Available since: 4.0.6

Parameters

• members : Object

Returns

• Ext.Base

  this

Appends an event handler to this object.

Available since: 1.1.0

Parameters

• eventName : String

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

• fn : Function

  The method the event invokes. Will be called with arguments given to fireEvent plus the options parameter described below.

• 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.

  Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

  This object 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'
        }
    });
    

  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
  });
  

  One can also specify options for each event handler separately:

  myGridPanel.on({
      cellClick: {fn: this.onCellClick, scope: this, single: true},
      mouseover: {fn: panel.onMouseOver, scope: panel}
  });
  

Adds listeners to any Observable object (or Ext.Element) which are automatically removed when this Component is destroyed.

Available since: 4.0.0

Parameters

• fn : Function (optional)

  If the ename parameter was an event name, this is the handler function.

• scope : Object (optional)

  If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

• opt : Object (optional)

  If the ename parameter was an event name, this is the addListener options.

Continue to fire event.

Available since: Ext JS 4.0.7

Parameters

• eventName : String
• args : Array
• bubbles : Boolean

Creates an event handling function which refires the event from this object as the passed event name.

Available since: 4.0.0

Parameters

• newName : Object

Returns

• Function

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');
        }
    }
});
