Animation instance
+ +This class is used to run keyframe based animations, which follows the CSS3 based animation structure. +Keyframe animations differ from typical from/to animations in that they offer the ability to specify values +at various points throughout the animation.
+ +Using Keyframes +The keyframes option is the most important part of specifying an animation when using this +class. A key frame is a point in a particular animation. We represent this as a percentage of the +total animation duration. At each key frame, we can specify the target values at that time. Note that +you must specify the values at 0% and 100%, the start and ending values. There is also a keyframe +event that fires after each key frame is reached.
+ +Example Usage +In the example below, we modify the values of the element at each fifth throughout the animation.
+ +Ext.create('Ext.fx.Animator', {
+ target: Ext.getBody().createChild({
+ style: {
+ width: '100px',
+ height: '100px',
+ 'background-color': 'red'
+ }
+ }),
+ duration: 10000, // 10 seconds
+ keyframes: {
+ 0: {
+ opacity: 1,
+ backgroundColor: 'FF0000'
+ },
+ 20: {
+ x: 30,
+ opacity: 0.5
+ },
+ 40: {
+ x: 130,
+ backgroundColor: '0000FF'
+ },
+ 60: {
+ y: 80,
+ opacity: 0.3
+ },
+ 80: {
+ width: 200,
+ y: 200
+ },
+ 100: {
+ opacity: 1,
+ backgroundColor: '00FF00'
+ }
+ }
+});
+Time to delay before starting the animation. Defaults to 0.
+Time to delay before starting the animation. Defaults to 0.
+Time in milliseconds for the animation to last. Defaults to 250.
+Time in milliseconds for the animation to last. Defaults to 250.
+Currently only for Component Animation: Only set a component's outer element size bypassing layouts. Set to true to do full layouts for every frame of the animation. Defaults to false.
+This describes how the intermediate values used during a transition will be calculated. It allows for a transition to change +speed over its duration.
+ +Note that cubic-bezier will create a custom easing curve following the CSS3 transition-timing-function specification http://www.w3.org/TR/css3-transitions/.transition-timing-function_tag. The four values specify points P1 and P2 of the curve
+as (x1, y1, x2, y2). All values must be in the range [0, 1] or the definition is invalid.
Number of times to execute the animation. Defaults to 1.
+Number of times to execute the animation. Defaults to 1.
+Animation keyframes follow the CSS3 Animation configuration pattern. 'from' is always considered '0%' and 'to' +is considered '100%'.Every keyframe declaration must have a keyframe rule for 0% and 100%, possibly defined using +"from" or "to". A keyframe declaration without these keyframe selectors is invalid and will not be available for +animation. The keyframe declaration for a keyframe rule consists of properties and values. Properties that are unable to +be animated are ignored in these rules, with the exception of 'easing' which can be changed at each keyframe. For example:
+ +keyframes : {
+ '0%': {
+ left: 100
+ },
+ '40%': {
+ left: 150
+ },
+ '60%': {
+ left: 75
+ },
+ '100%': {
+ left: 100
+ }
+}
+ (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'); }
+ }
+ }
+});
+Flag to determine if the animation is paused. Only set this to true if you need to +keep the Anim instance around to be unpaused later; otherwise call end.

+Either an object with event names as properties with a value of true

this reference) in which the handler function is executed.
+If omitted, defaults to the object which fired the event.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
+});

+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');
+ }
+}
+});
+The event name to bubble, or an Array of event names.
+Fires the specified event with the passed parameters (minus the event name).
+ + +An event may be set to bubble up an Observable parent hierarchy (See Ext.Component.getBubbleTarget) +by calling enableBubble.
+ +The name of the event to fire.
+Variable number of parameters are passed to handlers.
+returns false if any of the handlers return false otherwise it returns true.
+Checks to see if this object has any listeners for a specified event
+Checks to see if this object has any listeners for a specified event
+The name of the event to check for
+True if the event is being listened for, else false
+Sets observability on the passed class constructor.
+ +This makes any event fired on any instance of the passed class also fire a single event through +the class allowing for central handling of events on many instances at once.
+ +Usage:
+ +Ext.util.Observable.observe(Ext.data.Connection);
+Ext.data.Connection.on('beforerequest', function(con, options) {
+ console.log('Ajax request made to ' + options.url);
+});
