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.
-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.
-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.
[additional] Optional additional event names if multiple event names are being passed as separate parameters. -Usage:
- -this.addEvents('storeloaded', 'storecleared');
-Appends an event handler to this object.
-Appends an event handler to this object.
-The name of the event to listen for. May also be an object who's property names are event names. See
-The method the event invokes.
-(optional) The scope (this reference) in which the handler function is executed.
-If omitted, defaults to the object which fired the event.
(optional) An object containing handler configuration. -properties. This may contain any of the following properties:
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
-});

Starts capture on the specified Observable. All events will be passed -to the supplied function with the event name + standard signature of the event -before the event is fired. If the supplied function returns false, -the event will not fire.
-The Observable to capture events from.
-The function to call when an event is fired.
-(optional) The scope (this reference) in which the function is executed. Defaults to the Observable firing the event.
Removes all listeners for this object including the managed listeners
-Removes all listeners for this object including the managed listeners
-Removes all managed listeners for this object.
-Removes all managed listeners for this object.
-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);
-});
