/**
 * Base class that provides a common interface for publishing events. Subclasses are expected to to have a property
 * "events" with all the events defined, and, optionally, a property "listeners" with configured listeners defined.
 *
 * For example:
 *
 *     Ext.define('Employee', {
 *         extend: 'Ext.util.Observable',
 *         constructor: function(config){
 *             this.name = config.name;
 *             this.addEvents({
 *                 "fired" : true,
 *                 "quit" : true
 *             });
 *
 *             // Copy configured listeners into *this* object so that the base class's
 *             // constructor will add them.
 *             this.listeners = config.listeners;
 *
 *             // Call our superclass constructor to complete construction process.
 *             this.callParent(arguments)
 *         }
 *     });
 *
 * This could then be used like this:
 *
 *     var newEmployee = new Employee({
 *         name: employeeName,
 *         listeners: {
 *             quit: function() {
 *                 // By default, "this" will be the object that fired the event.
 *                 alert(this.name + " has quit!");
 *             }
 *         }
 *     });

     * 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 {@link #addListener} example for attaching multiple
     * handlers at once.
     *
     * **DOM events from Ext JS {@link Ext.Component Components}**
     *
     * While _some_ Ext JS 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 {@link Ext.view.View DataView}'s **`{@link
     * Ext.view.View#itemclick itemclick}`** 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,

     *                 element: 'body', //bind to the underlying body property on the panel

    /**
     * Appends an event handler to this object.
     *
     * @param {String} eventName The name of the event to listen for. May also be an object who's property names are
     * event names.
     * @param {Function} fn The method the event invokes.  Will be called with arguments given to
     * {@link #fireEvent} plus the `options` parameter described below.
     * @param {Object} [scope] The scope (`this` reference) in which the handler function is executed. **If
     * omitted, defaults to the object which fired the event.**
     * @param {Object} [options] An object containing handler configuration.
     *
     * **Note:** Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.
     *
     * This object 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 {@link 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
     *
     *   **This option is only valid for listeners bound to {@link Ext.Component Components}.** The name of a Component
     *   property which references an element to add a listener to.
     *
     *   This option is useful during Component construction to add DOM event listeners to elements of
     *   {@link Ext.Component 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'
     *           }
     *       });
     *
     * **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
     *     });
     *
     * One can also specify options for each event handler separately:
     *
     *     myGridPanel.on({
     *         cellClick: {fn: this.onCellClick, scope: this, single: true},
     *         mouseover: {fn: panel.onMouseOver, scope: panel}
     *     });
     *

/**
 * @class Ext.util.Animate
 * 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 {@link Ext.Element}, {@link Ext.CompositeElement}, 
 * {@link Ext.draw.Sprite}, {@link Ext.draw.CompositeSprite}, and {@link 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).
 * 
 * ## Animation Basics
 * 
 * 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. 
 * {@link Ext.fx.Anim#easing 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 
 * {@link Ext.fx.Anim#to to} property which is the end value for all animations.  
 * 
 * Popular element 'to' configurations are:
 * 
 *  - opacity
 *  - x
 *  - y
 *  - color
 *  - height
 *  - width 
 * 
 * Popular sprite 'to' configurations are:
 * 
 *  - translation
 *  - path
 *  - scale
 *  - stroke
 *  - rotation
 * 
 * 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 {@link Ext.fx.Anim#easing 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
 *         }
 *     });
 * 
 * ## Animation Queues
 * 
 * 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 {@link Ext.util.Animate#syncFx 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 {@link Ext.util.Animate#stopAnimation stopAnimation} method can be used to stop any 
 * currently running animations and clear any queued animations. 
 * 
 * ## Animation Keyframes

 * You can also set up complex animations with {@link Ext.fx.Anim#keyframes keyframes} which follow 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
 *             }
 *         }
 *     });
 * 
 * ## Animation Events
 * 
 * Each animation you create has events for {@link Ext.fx.Anim#beforeanimate beforeanimate}, 
 * {@link Ext.fx.Anim#afteranimate afteranimate}, and {@link Ext.fx.Anim#lastframe lastframe}.  
 * Keyframed animations adds an additional {@link Ext.fx.Animator#keyframe keyframe} event which 
 * fires for each keyframe in your animation.
 * 
 * All animations support the {@link Ext.util.Observable#listeners 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 {@link Ext.util.Animate#getActiveAnimation getActiveAnimation} 
 * method.  This method will return false if there are no active animations or return the currently 
 * running {@link 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
 *                 }
 *             });
 *         });
 *     }

     * <h3>Animating an {@link Ext.Element Element}</h3>

     * <h3>Animating a {@link Ext.Component Component}</h3>

     * </ul>
     * <p>For example, to animate a Window to a new size, ensuring that its internal layout, and any shadow is correct:</p>
     * <pre><code>
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,
        }
    });
});
</code></pre>
     * <p>For performance reasons, by default, the internal layout is only updated when the Window reaches its final <code>"to"</code> size. If dynamic updating of the Window's child
     * Components is required, then configure the animation with <code>dynamic: true</code> and the two child items will maintain their proportions during the animation.</p>

     *
     * You can define your own xtype on a custom {@link Ext.Component component} by specifying the
     * {@link Ext.Class#alias alias} config option with a prefix of `widget`. For example:

     * declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is
     * rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources
     * until they are actually needed. In complex, nested layouts containing many Components, this can make a
     * noticeable improvement in performance.

     *     var panel = new Ext.Panel({

     *           Ext.create('Ext.button.Button', {
     *              text: 'OK'
     *           })

     *           text: 'OK'
     *        }]
     *     };
     *
     * In the first example, the button will always be created immediately during the panel's initialization. With
     * many added Components, this approach could potentially slow the rendering of the page. In the second example,
     * the button will not be created or rendered until the panel is actually displayed in the browser. If the panel
     * is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and

 * The Connection class encapsulates a connection to the page's originating domain, allowing requests to be made either

 * to the statement immediately following the {@link #request} call. To process returned data, use a success callback
 * in the request options object, or an {@link #requestcomplete event listener}.
 *
 * # File Uploads
 *
 * File uploads are not performed using normal "Ajax" techniques, that is they are not performed using XMLHttpRequests.
 * Instead the form is submitted in the standard manner with the DOM &lt;form&gt; element temporarily modified to have its
 * target set to refer to a dynamically generated, hidden &lt;iframe&gt; which is inserted into the document but removed
 * after the return data has been gathered.
 *
 * The server response is parsed by the browser to create the document for the IFRAME. If the server is using JSON to
 * send the return object, then the Content-Type header must be set to "text/html" in order to tell the browser to
 * insert the text unchanged into the document body.
 *
 * Characters which are significant to an HTML parser must be sent as HTML entities, so encode `<` as `&lt;`, `&` as
 * `&amp;` etc.
 *
 * The response text is retrieved from the document, and a fake XMLHttpRequest object is created containing a
 * responseText property in order to conform to the requirements of event handlers and callbacks.
 *
 * Be aware that file upload packets are sent with the content type multipart/form and some server technologies
 * (notably JEE) may require some custom processing in order to retrieve parameter names and parameter values from the
 * packet content.
 *
 * Also note that it's not possible to check the response code of the hidden iframe, so the success handler will ALWAYS fire.

     * See [www.w3.org/TR/XMLHttpRequest/](http://www.w3.org/TR/XMLHttpRequest/) for details about
     * accessing elements of the response.
     *
     * @param {Function} options.success The function to be called upon success of the request.
     * The callback is passed the following parameters:
     * @param {Object} options.success.response The XMLHttpRequest object containing the response data.
     * @param {Object} options.success.options The parameter to the request call.
     *
     * @param {Function} options.failure The function to be called upon success of the request.
     * The callback is passed the following parameters:
     * @param {Object} options.failure.response The XMLHttpRequest object containing the response data.
     * @param {Object} options.failure.options The parameter to the request call.
     *
     * @param {Object} options.scope The scope in which to execute the callbacks: The "this" object for
     * the callback function. If the `url`, or `params` options were specified as functions from which to
     * draw values, then this also serves as the scope for those function calls. Defaults to the browser
     * window.
     *
     * @param {Number} options.timeout The timeout in milliseconds to be used for this request.
     * Defaults to 30 seconds.
     *
     * @param {Ext.Element/HTMLElement/String} options.form The `<form>` Element or the id of the `<form>`
     * to pull parameters from.
     *
     * @param {Boolean} options.isUpload **Only meaningful when used with the `form` option.**
     *
     * True if the form object is a file upload (will be set automatically if the form was configured
     * with **`enctype`** `"multipart/form-data"`).
     *
     * File uploads are not performed using normal "Ajax" techniques, that is they are **not**
     * performed using XMLHttpRequests. Instead the form is submitted in the standard manner with the
     * DOM `<form>` element temporarily modified to have its [target][] set to refer to a dynamically
     * generated, hidden `<iframe>` which is inserted into the document but removed after the return data
     * has been gathered.
     *
     * The server response is parsed by the browser to create the document for the IFRAME. If the
     * server is using JSON to send the return object, then the [Content-Type][] header must be set to
     * "text/html" in order to tell the browser to insert the text unchanged into the document body.
     *
     * The response text is retrieved from the document, and a fake XMLHttpRequest object is created
     * containing a `responseText` property in order to conform to the requirements of event handlers
     * and callbacks.
     *
     * Be aware that file upload packets are sent with the content type [multipart/form][] and some server
     * technologies (notably JEE) may require some custom processing in order to retrieve parameter names
     * and parameter values from the packet content.
