\n\nDOM events from ExtJs Components
\n\n\nWhile some ExtJs Component classes export selected DOM events (e.g. \"click\", \"mouseover\" etc), this\n\n\n
is usually only done when extra value can be added. For example the DataView's\nclick event passing the node clicked on. To access DOM\nevents directly from a child element of a Component, we need to specify the element option to\nidentify the Component property to add a DOM listener to:
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});\nAdds the specified events to the list of events which this Observable may fire.

\nA config object containing one or more event handlers to be added to this object during initialization. This\nshould be a valid listeners config object as specified in the addListener example for attaching multiple\nhandlers at once.
\n\nDOM events from Ext JS Components
\n\nWhile 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:
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});\nGet the reference to the current class from which this object was instantiated. Unlike statics,\nthis.self is scope-dependent and it's meant to be used for dynamic inheritance. See statics\nfor a detailed comparison
Ext.define('My.Cat', {\n statics: {\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n alert(this.self.speciesName); / dependent on 'this'\n\n return this;\n },\n\n clone: function() {\n return new this.self();\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat'\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\nAdds the specified events to the list of events which this Observable may fire.
\nEither an object with event names as properties with a value of true or the first\nevent name string if multiple event names are being passed as separate parameters. Usage:
this.addEvents({\n storeloaded: true,\n storecleared: true\n});\nAdditional event names if multiple event names are being passed as separate\nparameters. Usage:
\n\nthis.addEvents('storeloaded', 'storecleared');\nAppends an event handler to this object.
\nThe name of the event to listen for. May also be an object who's property names are\nevent names.
\n\nThe method the event invokes. Will be called with arguments given to\nfireEvent plus the options parameter described below.
The scope (this reference) in which the handler function is executed. If\nomitted, defaults to the object which fired the event.
An object containing handler configuration.
\n\n\n\n\nNote: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.
\n\n\n\n\nThis object may contain any of the following properties:
\n\n\n\n\nscope : Object
\n\nThe scope (this reference) in which the handler function is executed. If omitted, defaults to the object\nwhich fired the event.
delay : Number
\n\nThe number of milliseconds to delay the invocation of the handler after the event fires.
single : Boolean
\n\nTrue to add a handler to handle just the next firing of the event, and then remove itself.
buffer : Number
\n\nCauses the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of\nmilliseconds. If the event fires again within that time, the original handler is not invoked, but the new\nhandler is scheduled in its place.
target : Observable
\n\nOnly call the handler if the event was fired on the target Observable, not if the event was bubbled up from a\nchild Observable.
element : String
\n\nThis option is only valid for listeners bound to Components. The name of a Component\nproperty which references an element to add a listener to.
\n\nThis option is useful during Component construction to add DOM event listeners to elements of\nComponents which will exist only after the Component is rendered.\nFor example, to add a click listener to a Panel's body:
\n\nnew Ext.panel.Panel({\n title: 'The title',\n listeners: {\n click: this.handlePanelClick,\n element: 'body'\n }\n});\nCombining Options
\n\n\n\n\nUsing the options argument, it is possible to combine different types of listeners:
\n\n\n\n\nA delayed, one-time listener.
\n\n\n\n\nmyPanel.on('hide', this.handleClick, this, {\n single: true,\n delay: 100\n});\nAttaching multiple handlers in 1 call
\n\n\n\n\nThe method also allows for a single argument to be passed which is a config object containing properties which\nspecify multiple events. For example:
\n\n\n\n\nmyGridPanel.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});\nOne can also specify options for each event handler separately:
\n\n\n\n\nmyGridPanel.on({\n cellClick: {fn: this.onCellClick, scope: this, single: true},\n mouseover: {fn: panel.onMouseOver, scope: panel}\n});\nAdds listeners to any Observable object (or Ext.Element) which are automatically removed when this Component is\ndestroyed.
\nThe item to which to add a listener/listeners.
\n\nThe event name, or an object containing event name properties.
\n\nIf the ename parameter was an event name, this is the handler function.
If the ename parameter was an event name, this is the scope (this reference)\nin which the handler function is executed.
If the ename parameter was an event name, this is the\naddListener options.
Call the original method that was previously overridden with override
\n\nExt.define('My.Cat', {\n constructor: function() {\n alert(\"I'm a cat!\");\n\n return this;\n }\n});\n\nMy.Cat.override({\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n var instance = this.callOverridden();\n\n alert(\"Meeeeoooowwww\");\n\n return instance;\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\"\nThe arguments, either an array or the arguments object
Returns the result after calling the overridden method
\nCall the parent's overridden method. For example:
\n\nExt.define('My.own.A', {\n constructor: function(test) {\n alert(test);\n }\n});\n\nExt.define('My.own.B', {\n extend: 'My.own.A',\n\n constructor: function(test) {\n alert(test);\n\n this.callParent([test + 1]);\n }\n});\n\nExt.define('My.own.C', {\n extend: 'My.own.B',\n\n constructor: function() {\n alert(\"Going to call parent's overriden constructor...\");\n\n this.callParent(arguments);\n }\n});\n\nvar a = new My.own.A(1); // alerts '1'\nvar b = new My.own.B(1); // alerts '1', then alerts '2'\nvar c = new My.own.C(2); // alerts \"Going to call parent's overriden constructor...\"\n // alerts '2', then alerts '3'\nThe arguments, either an array or the arguments object\nfrom the current method, for example: this.callParent(arguments)
Returns the result from the superclass' method
\nRemoves all listeners for this object including the managed listeners
\nEnables 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.
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\nExample:
\n\nExt.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});\nFires the specified event with the passed parameters (minus the event name, plus the options object passed\nto addListener).
An event may be set to bubble up an Observable parent hierarchy (See Ext.Component.getBubbleTarget) by\ncalling enableBubble.
\nThe name of the event to fire.
\nVariable number of parameters are passed to handlers.
\nreturns false if any of the handlers return false otherwise it returns true.
\nInitialize configuration for this class. a typical example:
\n\nExt.define('My.awesome.Class', {\n // The default config\n config: {\n name: 'Awesome',\n isAwesome: true\n },\n\n constructor: function(config) {\n this.initConfig(config);\n\n return this;\n }\n});\n\nvar awesome = new My.awesome.Class({\n name: 'Super Awesome'\n});\n\nalert(awesome.getName()); // 'Super Awesome'\nmixins The mixin prototypes as key - value pairs
\nShorthand for addManagedListener.
\n\nAdds listeners to any Observable object (or Ext.Element) which are automatically removed when this Component is\ndestroyed.
\nThe item to which to add a listener/listeners.
\n\nThe event name, or an object containing event name properties.
\n\nIf the ename parameter was an event name, this is the handler function.
If the ename parameter was an event name, this is the scope (this reference)\nin which the handler function is executed.
If the ename parameter was an event name, this is the\naddListener options.
Shorthand for removeManagedListener.
\n\nRemoves listeners that were added by the mon method.
\nThe item from which to remove a listener/listeners.
\n\nThe event name, or an object containing event name properties.
\n\nIf the ename parameter was an event name, this is the handler function.
If the ename parameter was an event name, this is the scope (this reference)\nin which the handler function is executed.
Shorthand for addListener.
\n\nAppends an event handler to this object.
\nThe name of the event to listen for. May also be an object who's property names are\nevent names.
\n\nThe method the event invokes. Will be called with arguments given to\nfireEvent plus the options parameter described below.
The scope (this reference) in which the handler function is executed. If\nomitted, defaults to the object which fired the event.
An object containing handler configuration.
\n\n\n\n\nNote: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.
\n\n\n\n\nThis object may contain any of the following properties:
\n\n\n\n\nscope : Object
\n\nThe scope (this reference) in which the handler function is executed. If omitted, defaults to the object\nwhich fired the event.
delay : Number
\n\nThe number of milliseconds to delay the invocation of the handler after the event fires.
single : Boolean
\n\nTrue to add a handler to handle just the next firing of the event, and then remove itself.
buffer : Number
\n\nCauses the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of\nmilliseconds. If the event fires again within that time, the original handler is not invoked, but the new\nhandler is scheduled in its place.
target : Observable
\n\nOnly call the handler if the event was fired on the target Observable, not if the event was bubbled up from a\nchild Observable.
element : String
\n\nThis option is only valid for listeners bound to Components. The name of a Component\nproperty which references an element to add a listener to.
\n\nThis option is useful during Component construction to add DOM event listeners to elements of\nComponents which will exist only after the Component is rendered.\nFor example, to add a click listener to a Panel's body:
\n\nnew Ext.panel.Panel({\n title: 'The title',\n listeners: {\n click: this.handlePanelClick,\n element: 'body'\n }\n});\nCombining Options
\n\n\n\n\nUsing the options argument, it is possible to combine different types of listeners:
\n\n\n\n\nA delayed, one-time listener.
\n\n\n\n\nmyPanel.on('hide', this.handleClick, this, {\n single: true,\n delay: 100\n});\nAttaching multiple handlers in 1 call
\n\n\n\n\nThe method also allows for a single argument to be passed which is a config object containing properties which\nspecify multiple events. For example:
\n\n\n\n\nmyGridPanel.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});\nOne can also specify options for each event handler separately:
\n\n\n\n\nmyGridPanel.on({\n cellClick: {fn: this.onCellClick, scope: this, single: true},\n mouseover: {fn: panel.onMouseOver, scope: panel}\n});\nRemoves an event handler.
\nThe type of event the handler was associated with.
\n\nThe handler to remove. This must be a reference to the function passed into the\naddListener call.
\n\nThe scope originally specified for the handler. It must be the same as the\nscope argument specified in the original call to addListener or the listener will not be removed.
\n\nRemoves listeners that were added by the mon method.
\nThe item from which to remove a listener/listeners.
\n\nThe event name, or an object containing event name properties.
\n\nIf the ename parameter was an event name, this is the handler function.
If the ename parameter was an event name, this is the scope (this reference)\nin which the handler function is executed.
Resumes firing events (see suspendEvents).
\n\nIf events were suspended using the queueSuspended parameter, then all events fired\nduring event suspension will be sent to any listeners now.
Get the reference to the class from which this object was instantiated. Note that unlike self,\nthis.statics() is scope-independent and it always returns the class from which it was called, regardless of what\nthis points to during run-time
Ext.define('My.Cat', {\n statics: {\n totalCreated: 0,\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n var statics = this.statics();\n\n alert(statics.speciesName); // always equals to 'Cat' no matter what 'this' refers to\n // equivalent to: My.Cat.speciesName\n\n alert(this.self.speciesName); // dependent on 'this'\n\n statics.totalCreated++;\n\n return this;\n },\n\n clone: function() {\n var cloned = new this.self; // dependent on 'this'\n\n cloned.groupName = this.statics().speciesName; // equivalent to: My.Cat.speciesName\n\n return cloned;\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n },\n\n constructor: function() {\n this.callParent();\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat', then alerts 'Cat'\n\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Cat', then alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\nalert(clone.groupName); // alerts 'Cat'\n\nalert(My.Cat.totalCreated); // alerts 3\nSuspends the firing of all events. (see resumeEvents)
\nPass as true to queue up suspended events to be fired\nafter the resumeEvents call instead of discarding all suspended events.
\nShorthand for removeListener.
\n\nRemoves an event handler.
\nThe type of event the handler was associated with.
\n\nThe handler to remove. This must be a reference to the function passed into the\naddListener call.
