Class Ext.util.TapRepeater

Package:	Ext.util
Defined In:	TapRepeater.js
Class:	TapRepeater
Extends:	Observable

A wrapper class which can be applied to any element. Fires a "tap" event while touching the device. The interval between firings may be specified in the config but defaults to 20 milliseconds.

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 a child element of a Component, we need to specify this explicitly: `new Ext.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'); } } } });`	Observable

Method		Defined By
	TapRepeater( `Mixed el`, `Object config` ) Parameters: `el` : Mixed The element to listen on `config` : Object Returns: void	TapRepeater
	addEvents( `Object\|String o`, `string Optional.` ) : void 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: `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. `Optional.` : string Event name if multiple event names are being passed as separate parameters. Usage: `this.addEvents('storeloaded', 'storecleared');` Returns: void	Observable
	addListener( `String eventName`, `Function handler`, [`Object scope`], [`Object options`] ) : void Appends an event handler to this object. Appends an event handler to this object. Parameters: `eventName` : String The name of the event to listen for. `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 The element reference on the component to bind the event to. This is used to bind DOM events to underlying elements on Components. - This option is only valid for listeners bound to Components Combining Options Using the options argument, it is possible to combine different types of listeners: A delayed, one-time listener. `myPanel.on('hide', this.onClick, 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 handlers. Returns: void	Observable
	addManagedListener( `Observable\|Element item`, `Object\|String ename`, `Function fn`, `Object scope`, `Object opt` ) : void Adds listeners to any Observable object (or Element) which are automatically removed when this Component is destroyed... Adds listeners to any Observable object (or Element) which are automatically removed when this Component is destroyed. Parameters: `item` : Observable\|Element The item to which to add a listener/listeners. `ename` : Object\|String The event name, or an object containing event name properties. `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. Returns: void	Observable
	clearListeners() : void Removes all listeners for this object including the managed listeners Removes all listeners for this object including the managed listeners Parameters: None. Returns: void	Observable
	clearManagedListeners() : void Removes all managed listeners for this object. Removes all managed listeners for this object. Parameters: None. Returns: void	Observable
	enableBubble( `String/Array events` ) : void 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, { // Add functionality to Field's initComponent to enable the change event to bubble initComponent : Ext.createSequence(Ext.form.Field.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'); } } }); Parameters: `events` : String/Array The event name to bubble, or an Array of event names. Returns: void	Observable
