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
+ }
+ });
+ });
+}

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 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: {

+ 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.
