This animation class is a mixin.
- -Ext.util.Animate provides an API for the creation of animated transitions of properties and styles.
-This class is used as a mixin and currently applied to Ext.core.Element, Ext.CompositeElement,
-Ext.draw.Sprite, Ext.draw.CompositeSprite, and Ext.Component. Note that Components
-have a limited subset of what attributes can be animated such as top, left, x, y, height, width, and
-opacity (color, paddings, and margins can not be animated).
All animations require three things - easing, duration, and to (the final end value for each property)
-you wish to animate. Easing and duration are defaulted values specified below.
-Easing describes how the intermediate values used during a transition will be calculated.
-Easing allows for a transition to change speed over its duration.
-You may use the defaults for easing and duration, but you must always set a
-to property which is the end value for all animations.
Popular element 'to' configurations are:
- -Popular sprite 'to' configurations are:
- -The default duration for animations is 250 (which is a 1/4 of a second). Duration is denoted in -milliseconds. Therefore 1 second is 1000, 1 minute would be 60000, and so on. The default easing curve -used for all animations is 'ease'. Popular easing functions are included and can be found in Easing.
- -For example, a simple animation to fade out an element with a default easing and duration:
- -var p1 = Ext.get('myElementId');
-
-p1.animate({
- to: {
- opacity: 0
- }
-});
-To make this animation fade out in a tenth of a second:
- -var p1 = Ext.get('myElementId');
-
-p1.animate({
- duration: 100,
- to: {
- opacity: 0
- }
-});
-By default all animations are added to a queue which allows for animation via a chain-style API. -For example, the following code will queue 4 animations which occur sequentially (one right after the other):
- -p1.animate({
- to: {
- x: 500
- }
-}).animate({
- to: {
- y: 150
- }
-}).animate({
- to: {
- backgroundColor: '#f00' //red
- }
-}).animate({
- to: {
- opacity: 0
- }
-});
-You can change this behavior by calling the syncFx method and all -subsequent animations for the specified target will be run concurrently (at the same time).
- -p1.syncFx(); //this will make all animations run at the same time
-
-p1.animate({
- to: {
- x: 500
- }
-}).animate({
- to: {
- y: 150
- }
-}).animate({
- to: {
- backgroundColor: '#f00' //red
- }
-}).animate({
- to: {
- opacity: 0
- }
-});
-This works the same as:
- -p1.animate({
- to: {
- x: 500,
- y: 150,
- backgroundColor: '#f00' //red
- opacity: 0
- }
-});
-The stopAnimation method can be used to stop any -currently running animations and clear any queued animations.
- -You can also set up complex animations with keyframe which follows the -CSS3 Animation configuration pattern. Note rotation, translation, and scaling can only be done for sprites. -The previous example can be written with the following syntax:
- -p1.animate({
- duration: 1000, //one second total
- keyframes: {
- 25: { //from 0 to 250ms (25%)
- x: 0
- },
- 50: { //from 250ms to 500ms (50%)
- y: 0
- },
- 75: { //from 500ms to 750ms (75%)
- backgroundColor: '#f00' //red
- },
- 100: { //from 750ms to 1sec
- opacity: 0
- }
- }
-});
-Each animation you create has events for beforeanimation,
-afteranimate, and lastframe.
-Keyframed animations adds an additional keyframe event which
-fires for each keyframe in your animation.
All animations support the listeners configuration to attact functions to these events.
- -startAnimate: function() {
- var p1 = Ext.get('myElementId');
- p1.animate({
- duration: 100,
- to: {
- opacity: 0
- },
- listeners: {
- beforeanimate: function() {
- // Execute my custom method before the animation
- this.myBeforeAnimateFn();
- },
- afteranimate: function() {
- // Execute my custom method after the animation
- this.myAfterAnimateFn();
- },
- scope: this
- });
-},
-myBeforeAnimateFn: function() {
- // My custom logic
-},
-myAfterAnimateFn: function() {
- // My custom logic
-}
-Due to the fact that animations run asynchronously, you can determine if an animation is currently -running on any target by using the getActiveAnimation -method. This method will return false if there are no active animations or return the currently -running Ext.fx.Anim instance.
- -In this example, we're going to wait for the current animation to finish, then stop any other -queued animations before we fade our element's opacity to 0:
- -var curAnim = p1.getActiveAnimation();
-if (curAnim) {
- curAnim.on('afteranimate', function() {
- p1.stopAnimation();
- p1.animate({
- to: {
- opacity: 0
- }
- });
- });

-@deprecated 4.0 Replaced by getActiveAnimation -Returns thq current animation if this object has any effects actively running or queued, else returns false.
-Perform custom animation on this object.
-
This method is applicable to both the the Component class and the Element class. -It performs animated transitions of certain properties of this object over a specified timeline.
-The sole parameter is an object which specifies start property values, end property values, and properties which
-describe the timeline. Of the properties listed below, only to is mandatory.

This must be a value between 0 and 1.Be aware than animating an Element which is being used by an Ext Component without in some way informing the Component about the changed element state -will result in incorrect Component behaviour. This is because the Component will be using the old state of the element. To avoid this problem, it is now possible to -directly animate certain properties of Components.

-myWindow = Ext.create('Ext.window.Window', {
- title: 'Test Component animation',
- width: 500,
- height: 300,
- layout: {
- type: 'hbox',
- align: 'stretch'
- },
- items: [{
- title: 'Left: 33%',
- margins: '5 0 5 5',
- flex: 1
- }, {
- title: 'Left: 66%',
- margins: '5 5 5 5',
- flex: 2
- }]
-});
-myWindow.show();
-myWindow.header.el.on('click', function() {
- myWindow.animate({
- to: {
- width: (myWindow.getWidth() == 500) ? 700 : 500,
- height: (myWindow.getHeight() == 300) ? 400 : 300,
- }
- });
-});
-For performance reasons, by default, the internal layout is only updated when the Window reaches its final "to" size. If dynamic updating of the Window's child
-Components is required, then configure the animation with dynamic: true and the two child items will maintain their proportions during the animation.
