api : Object

Specific urls to call on CRUD action methods \"create\", \"read\", \"update\" and \"destroy\". ...

Specific urls to call on CRUD action methods \"create\", \"read\", \"update\" and \"destroy\". Defaults to:

\n\n

api: {\n    create  : undefined,\n    read    : undefined,\n    update  : undefined,\n    destroy : undefined\n}\n

\n\n

The url is built based upon the action being executed [create|read|update|destroy] using the commensurate\napi property, or if undefined default to the configured\nExt.data.Store.url.

\n\n

For example:

\n\n

api: {\n    create  : '/controller/new',\n    read    : '/controller/load',\n    update  : '/controller/update',\n    destroy : '/controller/destroy_action'\n}\n

\n\n

If the specific URL for a given CRUD action is undefined, the CRUD action request will be directed to the\nconfigured url.

DOM events from Ext JS Components

\n\n

While some Ext JS Component classes export selected DOM events (e.g. \"click\", \"mouseover\" etc), this is usually\nonly done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a\nchild element of a Component, we need to specify the element option to identify the Component property to add a\nDOM listener to:

\n\n

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

hasListeners : Objectreadonly

This object holds a key for any event that has a listener. ...

This object holds a key for any event that has a listener. The listener may be set\ndirectly on the instance, or on its class or a super class (via observe) or\non the MVC EventBus. The values of this object are truthy\n(a non-zero number) and falsy (0 or undefined). They do not represent an exact count\nof listeners. The value for an event is truthy if the event must be fired and is\nfalsy if there is no need to fire the event.

\n\n

The intended use of this property is to avoid the expense of fireEvent calls when\nthere are no listeners. This can be particularly helpful when one would otherwise\nhave to call fireEvent hundreds or thousands of times. It is used like this:

\n\n

 if (this.hasListeners.foo) {\n     this.fireEvent('foo', this, arg1);\n }\n

addEvents( Object/String... eventNames )

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

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

Parameters

eventNames : Object/String...
Either an object with event names as properties with\na value of true. For example:
\n\n
```
this.addEvents({\n    storeloaded: true,\n    storecleared: true\n});\n
```
\n\n
Or any number of event names as separate parameters. For example:
\n\n
```
this.addEvents('storeloaded', 'storecleared');\n
```
\n

addListener( String/Object eventName, [Function fn], [Object scope], [Object options] )

Appends an event handler to this object. ...

Appends an event handler to this object. For example:

\n\n

myGridPanel.on(\"mouseover\", this.onMouseOver, this);\n

\n\n

The method also allows for a single argument to be passed which is a config object\ncontaining properties which specify multiple events. For example:

\n\n

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

\n\n

One can also specify options for each event handler separately:

\n\n

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

\n\n

Names of methods in a specified scope may also be used. Note that\nscope MUST be specified to use this option:

\n\n

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

Parameters

eventName : String/Object
The name of the event to listen for.\nMay also be an object who's property names are event names.
\n\n
fn : Function (optional)
The method the event invokes, or if scope is specified, the name* of the method within\nthe specified scope. Will be called with arguments\ngiven to fireEvent plus the options parameter described below.
\n\n
scope : Object (optional)
The scope (this reference) in which the handler function is\nexecuted. If omitted, defaults to the object which fired the event.
\n\n
options : Object (optional)
An object containing handler configuration.
\n\n\n\n\n
Note: Unlike in ExtJS 3.x, the options object will also be passed as the last\nargument to every event handler.
\n\n\n\n\n
This object may contain any of the following properties:
\n\n
- scope : Object
  The scope (this reference) in which the handler function is executed. If omitted,\n defaults to the object which fired the event.
  \n\n
- delay : Number
  The number of milliseconds to delay the invocation of the handler after the event fires.
  \n\n
- single : Boolean
  True to add a handler to handle just the next firing of the event, and then remove itself.
  \n\n
- buffer : Number
  Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed\n by the specified number of milliseconds. If the event fires again within that time,\n the original handler is not invoked, but the new handler is scheduled in its place.
  \n\n
- target : Ext.util.Observable
  Only call the handler if the event was fired on the target Observable, not if the event\n was bubbled up from a child Observable.
  \n\n
- element : String
  This option is only valid for listeners bound to Components.\n The name of a Component property which references an element to add a listener to.
  \n\n\n\n\n
  This option is useful during Component construction to add DOM event listeners to elements of\n Components which will exist only after the Component is rendered.\n For example, to add a click listener to a Panel's body:
  \n\n\n\n\n
```
  new Ext.panel.Panel({\n      title: 'The title',\n      listeners: {\n          click: this.handlePanelClick,\n          element: 'body'\n      }\n  });\n
```
  \n\n\n\n\n
  Combining Options
  \n\n\n\n\n
  Using the options argument, it is possible to combine different types of listeners:
  \n\n\n\n\n
  A delayed, one-time listener.
  \n\n\n\n\n
```
myPanel.on('hide', this.handleClick, this, {\n    single: true,\n    delay: 100\n});\n
```
  \n\n

batch( Object options ) : Ext.data.Batch

Performs a batch of Operations, in the order specified by batchOrder. ...

Performs a batch of Operations, in the order specified by batchOrder. Used\ninternally by Ext.data.Store's sync method. Example usage:

\n\n

myProxy.batch({\n    create : [myModel1, myModel2],\n    update : [myModel3],\n    destroy: [myModel4, myModel5]\n});\n

\n\n

Where the myModel* above are Model instances - in this case 1 and 2 are new instances and\nhave not been saved before, 3 has been saved previously but needs to be updated, and 4 and 5 have already been\nsaved but should now be destroyed.

\n\n

Note that the previous version of this method took 2 arguments (operations and listeners). While this is still\nsupported for now, the current signature is now a single options argument that can contain both operations and\nlisteners, in addition to other options. The multi-argument signature will likely be deprecated in a future release.

Parameters

options : Object
Object containing one or more properties supported by the batch method:
\n
- operations : Object
  Object containing the Model instances to act upon, keyed by action name
  \n
- listeners : Object (optional)
  Event listeners object passed straight through to the Batch -\nsee Ext.data.Batch for details
  \n
- batch : Ext.data.Batch/Object (optional)
  A Ext.data.Batch object (or batch config to apply\nto the created batch). If unspecified a default batch will be auto-created.
  \n
- callback : Function (optional)
  The function to be called upon completion of processing the batch.\nThe callback is called regardless of success or failure and is passed the following parameters:
  \n
  Parameters
  - batch : Ext.data.Batch
    The batch that was processed,\ncontaining all operations in their current state after processing
    \n
  - options : Object
    The options argument that was originally passed into batch
    \n
- success : Function (optional)
  The function to be called upon successful completion of the batch. The\nsuccess function is called only if no exceptions were reported in any operations. If one or more exceptions\noccurred then the failure function will be called instead. The success function is called\nwith the following parameters:
  \n
  Parameters
  - batch : Ext.data.Batch
    The batch that was processed,\ncontaining all operations in their current state after processing
    \n
  - options : Object
    The options argument that was originally passed into batch
    \n
- failure : Function (optional)
  The function to be called upon unsuccessful completion of the batch. The\nfailure function is called when one or more operations returns an exception during processing (even if some\noperations were also successful). In this case you can check the batch's exceptions array to see exactly which operations had exceptions. The failure function is called with the\nfollowing parameters:
  \n
  Parameters
  - batch : Ext.data.Batch
    The batch that was processed,\ncontaining all operations in their current state after processing
    \n
  - options : Object
    The options argument that was originally passed into batch
    \n
- scope : Object (optional)

\n\n

Parameters

args : Array/Arguments
The arguments, either an array or the arguments object\nfrom the current method, for example: this.callOverridden(arguments)
\n

Returns

Object
Returns the result of calling the overridden method
\n

callParent( Array/Arguments args ) : Objectprotected

Call the \"parent\" method of the current method. ...

Call the \"parent\" method of the current method. That is the method previously\noverridden by derivation or by an override (see Ext.define).

\n\n

 Ext.define('My.Base', {\n     constructor: function (x) {\n         this.x = x;\n     },\n\n     statics: {\n         method: function (x) {\n             return x;\n         }\n     }\n });\n\n Ext.define('My.Derived', {\n     extend: 'My.Base',\n\n     constructor: function () {\n         this.callParent([21]);\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // alerts 21\n

\n\n

This can be used with an override as follows:

\n\n

 Ext.define('My.DerivedOverride', {\n     override: 'My.Derived',\n\n     constructor: function (x) {\n         this.callParent([x*2]); // calls original My.Derived constructor\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // now alerts 42\n

\n\n

This also works with static methods.

\n\n

 Ext.define('My.Derived2', {\n     extend: 'My.Base',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Base.method\n         }\n     }\n });\n\n alert(My.Base.method(10);     // alerts 10\n alert(My.Derived2.method(10); // alerts 20\n

\n\n

Lastly, it also works with overridden static methods.

\n\n

 Ext.define('My.Derived2Override', {\n     override: 'My.Derived2',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Derived2.method\n         }\n     }\n });\n\n alert(My.Derived2.method(10); // now alerts 40\n

enableBubble( String/String[] eventNames )

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

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

\n\n

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

\n\n

Example:

\n\n

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

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

\n\n

One can also specify options for each event handler separately:

\n\n

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

\n\n

Names of methods in a specified scope may also be used. Note that\nscope MUST be specified to use this option:

\n\n

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

Parameters

eventName : String/Object
The name of the event to listen for.\nMay also be an object who's property names are event names.
\n\n
fn : Function (optional)
The method the event invokes, or if scope is specified, the name* of the method within\nthe specified scope. Will be called with arguments\ngiven to fireEvent plus the options parameter described below.
\n\n
scope : Object (optional)
The scope (this reference) in which the handler function is\nexecuted. If omitted, defaults to the object which fired the event.
\n\n
options : Object (optional)
An object containing handler configuration.
\n\n\n\n\n
Note: Unlike in ExtJS 3.x, the options object will also be passed as the last\nargument to every event handler.
\n\n\n\n\n
This object may contain any of the following properties:
\n\n
- scope : Object
  The scope (this reference) in which the handler function is executed. If omitted,\n defaults to the object which fired the event.
  \n\n
- delay : Number
  The number of milliseconds to delay the invocation of the handler after the event fires.
  \n\n
- single : Boolean
  True to add a handler to handle just the next firing of the event, and then remove itself.
  \n\n
- buffer : Number
  Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed\n by the specified number of milliseconds. If the event fires again within that time,\n the original handler is not invoked, but the new handler is scheduled in its place.
  \n\n
- target : Ext.util.Observable
  Only call the handler if the event was fired on the target Observable, not if the event\n was bubbled up from a child Observable.
  \n\n
- element : String
  This option is only valid for listeners bound to Components.\n The name of a Component property which references an element to add a listener to.
  \n\n\n\n\n
  This option is useful during Component construction to add DOM event listeners to elements of\n Components which will exist only after the Component is rendered.\n For example, to add a click listener to a Panel's body:
  \n\n\n\n\n
```
  new Ext.panel.Panel({\n      title: 'The title',\n      listeners: {\n          click: this.handlePanelClick,\n          element: 'body'\n      }\n  });\n
```
  \n\n\n\n\n
  Combining Options
  \n\n\n\n\n
  Using the options argument, it is possible to combine different types of listeners:
  \n\n\n\n\n
  A delayed, one-time listener.
  \n\n\n\n\n
```
myPanel.on('hide', this.handleClick, this, {\n    single: true,\n    delay: 100\n});\n
```

relayEvents( Object origin, String[] events, [String prefix] )

Relays selected events from the specified Observable as if the events were fired by this. ...

Relays selected events from the specified Observable as if the events were fired by this.

\n\n

For example if you are extending Grid, you might decide to forward some events from store.\nSo you can do this inside your initComponent:

\n\n

this.relayEvents(this.getStore(), ['load']);\n

\n\n

The grid instance will then have an observable 'load' event which will be passed the\nparameters of the store's load event and any function fired with the grid's load event\nwould have access to the grid using the this keyword.

Parameters

origin : Object
The Observable whose events this object is to relay.
\n
events : String[]
Array of event names to relay.
\n
prefix : String (optional)
A common prefix to prepend to the event names. For example:
\n\n
```
this.relayEvents(this.getStore(), ['load', 'clear'], 'store');\n
```
\n\n
Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.

Ext.define('My.Cat', {\n    constructor: function() {\n        alert(\"I'm a cat!\");\n    }\n});\n\nMy.Cat.override({\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callParent(arguments);\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n                          // alerts \"I'm a cat!\"\n                          // alerts \"Meeeeoooowwww\"\n

\n\n

As of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:

\n\n

Ext.define('My.CatOverride', {\n    override: 'My.Cat',\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callParent(arguments);\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n

\n\n

The above accomplishes the same result but can be managed by the Ext.Loader\nwhich can properly order the override and its target class and the build process\ncan determine whether the override is needed based on the required state of the\ntarget class (My.Cat).

This method has been deprecated since 4.1.0

Use Ext.define instead
