/**
 * 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', {
 *         mixins: {
 *             observable: 'Ext.util.Observable'
 *         },
 *
 *         constructor: function (config) {
 *             // The Observable constructor copies all of the properties of `config` on
 *             // to `this` using {@link Ext#apply}. Further, the `listeners` property is
 *             // processed to add listeners.
 *             //
 *             this.mixins.observable.constructor.call(this, config);
 *
 *             this.addEvents(
 *                 'fired',
 *                 'quit'
 *             );
 *         }
 *     });
 *
 * 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

     * **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({

     *         height: 200,

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

     *     });
     *
     * *Names* of methods in a specified scope may also be used. Note that
     * `scope` MUST be specified to use this option:
     *
     *     myGridPanel.on({
     *         cellClick: {fn: 'onCellClick', scope: this, single: true},
     *         mouseover: {fn: 'onMouseOver', scope: panel}
     *     });
     *
     * @param {String/Object} 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, or *if `scope` is specified, the *name* of the method within
     * the specified `scope`.  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:
     *
     * @param {Object} options.scope
     *   The scope (`this` reference) in which the handler function is executed. **If omitted,
     *   defaults to the object which fired the event.**
     *
     * @param {Number} options.delay
     *   The number of milliseconds to delay the invocation of the handler after the event fires.
     *
     * @param {Boolean} options.single
     *   True to add a handler to handle just the next firing of the event, and then remove itself.
     *
     * @param {Number} options.buffer
     *   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.
     *
     * @param {Ext.util.Observable} options.target
     *   Only call the handler if the event was fired on the target Observable, _not_ if the event
     *   was bubbled up from a child Observable.
     *
     * @param {String} options.element
     *   **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
     *     });

 *
 * Associations enable you to express relationships between different {@link Ext.data.Model Models}. Let's say we're
 * writing an ecommerce system where Users can make Orders - there's a relationship between these Models that we can
 * express like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         fields: ['id', 'name', 'email'],
 *
 *         hasMany: {model: 'Order', name: 'orders'}
 *     });
 *
 *     Ext.define('Order', {
 *         extend: 'Ext.data.Model',
 *         fields: ['id', 'user_id', 'status', 'price'],
 *
 *         belongsTo: 'User'
 *     });
 *
 * We've set up two models - User and Order - and told them about each other. You can set up as many associations on
 * each Model as you need using the two default types - {@link Ext.data.HasManyAssociation hasMany} and {@link
 * Ext.data.BelongsToAssociation belongsTo}. There's much more detail on the usage of each of those inside their
 * documentation pages. If you're not familiar with Models already, {@link Ext.data.Model there is plenty on those too}.

/**
 * @author Don Griffin
 *
 * This class is a base for all id generators. It also provides lookup of id generators by
 * their id.
 * 
 * Generally, id generators are used to generate a primary key for new model instances. There
 * are different approaches to solving this problem, so this mechanism has both simple use
 * cases and is open to custom implementations. A {@link Ext.data.Model} requests id generation
 * using the {@link Ext.data.Model#idgen} property.
 *
 * # Identity, Type and Shared IdGenerators
 *
 * It is often desirable to share IdGenerators to ensure uniqueness or common configuration.
 * This is done by giving IdGenerator instances an id property by which they can be looked
 * up using the {@link #get} method. To configure two {@link Ext.data.Model Model} classes
 * to share one {@link Ext.data.SequentialIdGenerator sequential} id generator, you simply
 * assign them the same id:
 *
 *     Ext.define('MyApp.data.MyModelA', {
 *         extend: 'Ext.data.Model',
 *         idgen: {
 *             type: 'sequential',
 *             id: 'foo'
 *         }
 *     });
 *
 *     Ext.define('MyApp.data.MyModelB', {
 *         extend: 'Ext.data.Model',
 *         idgen: {
 *             type: 'sequential',
 *             id: 'foo'
 *         }
 *     });
 *
 * To make this as simple as possible for generator types that are shared by many (or all)
 * Models, the IdGenerator types (such as 'sequential' or 'uuid') are also reserved as
 * generator id's. This is used by the {@link Ext.data.UuidGenerator} which has an id equal
 * to its type ('uuid'). In other words, the following Models share the same generator:
 *
 *     Ext.define('MyApp.data.MyModelX', {
 *         extend: 'Ext.data.Model',
 *         idgen: 'uuid'
 *     });
 *
 *     Ext.define('MyApp.data.MyModelY', {
 *         extend: 'Ext.data.Model',
 *         idgen: 'uuid'
 *     });
 *
 * This can be overridden (by specifying the id explicitly), but there is no particularly
 * good reason to do so for this generator type.
 *
 * # Creating Custom Generators
 * 
 * An id generator should derive from this class and implement the {@link #generate} method.
 * The constructor will apply config properties on new instances, so a constructor is often
 * not necessary.
 *
 * To register an id generator type, a derived class should provide an `alias` like so:
 *
 *     Ext.define('MyApp.data.CustomIdGenerator', {
 *         extend: 'Ext.data.IdGenerator',
 *         alias: 'idgen.custom',
 *
 *         configProp: 42, // some config property w/default value
 *
 *         generate: function () {
 *             return ... // a new id
 *         }
 *     });
 *
 * Using the custom id generator is then straightforward:
 *
 *     Ext.define('MyApp.data.MyModel', {
 *         extend: 'Ext.data.Model',
 *         idgen: 'custom'
 *     });
 *     // or...
 *
 *     Ext.define('MyApp.data.MyModel', {
 *         extend: 'Ext.data.Model',
 *         idgen: {
 *             type: 'custom',
 *             configProp: value
 *         }
 *     });
 *
 * It is not recommended to mix shared generators with generator configuration. This leads
 * to unpredictable results unless all configurations match (which is also redundant). In
 * such cases, a custom generator with a default id is the best approach.
 *
 *     Ext.define('MyApp.data.CustomIdGenerator', {
 *         extend: 'Ext.data.SequentialIdGenerator',
 *         alias: 'idgen.custom',
 *
 *         id: 'custom', // shared by default
 *
 *         prefix: 'ID_',
 *         seed: 1000
 *     });
 *
 *     Ext.define('MyApp.data.MyModelX', {
 *         extend: 'Ext.data.Model',
 *         idgen: 'custom'
 *     });
 *
 *     Ext.define('MyApp.data.MyModelY', {
 *         extend: 'Ext.data.Model',
 *         idgen: 'custom'
 *     });
 *
 *     // the above models share a generator that produces ID_1000, ID_1001, etc..

 *
 * # 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.

     * postprocessing in a callback because it is passed to callback functions.)
     *
     * @param {String/Function} options.url The URL to which to send the request, or a function
     * to call which returns a URL string. The scope of the function is specified by the `scope` option.
     * Defaults to the configured `url`.
     *
     * @param {Object/String/Function} options.params An object containing properties which are
     * used as parameters to the request, a url encoded string or a function to call to get either. The scope
     * of the function is specified by the `scope` option.
     *
     * @param {String} options.method The HTTP method to use
     * for the request. Defaults to the configured method, or if no method was configured,
     * "GET" if no parameters are being sent, and "POST" if parameters are being sent.  Note that
     * the method name is case-sensitive and should be all caps.
     *
     * @param {Function} options.callback The function to be called upon receipt of the HTTP response.
     * The callback is called regardless of success or failure and is passed the following parameters:
     * @param {Object} options.callback.options The parameter to the request call.
     * @param {Boolean} options.callback.success True if the request succeeded.
     * @param {Object} options.callback.response The XMLHttpRequest object containing the response data.
     * 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.

/**
 * 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
 *                 }
 *             });
 *         });
 *     }
 */
Ext.define('Ext.util.Animate', {

    uses: ['Ext.fx.Manager', 'Ext.fx.Anim'],

    /**
     * Perform custom animation on this object.
     *
     * This method is applicable to both the {@link Ext.Component Component} class and the {@link Ext.Element Element}

     *
     * The sole parameter is an object which specifies start property values, end property values, and properties which
     * describe the timeline. 
     *
     * ### Animating an {@link Ext.Element Element}
     *
     * When animating an Element, the following properties may be specified in `from`, `to`, and `keyframe` objects:
     *
     *   - `x` - The page X position in pixels.
     *
     *   - `y` - The page Y position in pixels
     *
     *   - `left` - The element's CSS `left` value. Units must be supplied.
     *
     *   - `top` - The element's CSS `top` value. Units must be supplied.
     *
     *   - `width` - The element's CSS `width` value. Units must be supplied.
     *
     *   - `height` - The element's CSS `height` value. Units must be supplied.
     *
     *   - `scrollLeft` - The element's `scrollLeft` value.
     *
     *   - `scrollTop` - The element's `scrollLeft` value.
     *
     *   - `opacity` - The element's `opacity` value. 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.**
     *
     * ### Animating a {@link Ext.Component Component}
     *
     * When animating a Component, the following properties may be specified in `from`, `to`, and `keyframe` objects:
     *
     *   - `x` - The Component's page X position in pixels.
     *
     *   - `y` - The Component's page Y position in pixels
     *
     *   - `left` - The Component's `left` value in pixels.
     *
     *   - `top` - The Component's `top` value in pixels.
     *
     *   - `width` - The Component's `width` value in pixels.
     *
     *   - `width` - The Component's `width` value in pixels.
     *
     *   - `dynamic` - Specify as true to update the Component's layout (if it is a Container) at every frame of the animation.
     *     *Use sparingly as laying out on every intermediate size change is an expensive operation.*
     *
     * For example, to animate a Window to a new size, ensuring that its internal layout, and any shadow is correct:
     *
     *     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.
     *
     * @param {Object} config An object containing properties which describe the animation's start and end states, and
     * the timeline of the animation. Of the properties listed below, only **`to`** is mandatory.
     * 
     * Properties include:
     *
     * @param {Object} config.from
     * An object which specifies start values for the properties being animated. If not supplied, properties are
     * animated from current settings. The actual properties which may be animated depend upon ths object being
     * animated. See the sections below on Element and Component animation.
     *
     * @param {Object} config.to
     * An object which specifies end values for the properties being animated.
     *
     * @param {Number} config.duration
     * The duration **in milliseconds** for which the animation will run.
     *
     * @param {String} config.easing
     * A string value describing an easing type to modify the rate of change from the default linear to non-linear.
     * Values may be one of:
     *
     *   - ease
     *   - easeIn

/**
 * This mixin enables classes to declare relationships to child elements and provides the
 * mechanics for acquiring the {@link Ext.Element elements} and storing them on an object
 * instance as properties.
 *
 * This class is used by {@link Ext.Component components} and {@link Ext.layout.container.Container container layouts} to
 * manage their child elements.
 * 
 * A typical component that uses these features might look something like this:
 * 
 *      Ext.define('Ext.ux.SomeComponent', {
 *          extend: 'Ext.Component',
 *          
 *          childEls: [
 *              'bodyEl'
 *          ],
 *          
 *          renderTpl: [
 *              '&lt;div id="{id}-bodyEl"&gt;&lt;/div&gt;'
 *          ],
 *          
 *          // ...
 *      });
 * 
 * The `childEls` array lists one or more relationships to child elements managed by the
 * component. The items in this array can be either of the following types:
 * 
 * - String: the id suffix and property name in one. For example, "bodyEl" in the above
 * example means a "bodyEl" property will be added to the instance with the result of
 * {@link Ext#get} given "componentId-bodyEl" where "componentId" is the component instance's
 * id.
 * - Object: with a `name` property that names the instance property for the element, and
 * one of the following additional properties:
 *      - `id`: The full id of the child element.
 *      - `itemId`: The suffix part of the id to which "componentId-" is prepended.
 *      - `select`: A selector that will be passed to {@link Ext#select}.
 *      - `selectNode`: A selector that will be passed to {@link Ext.DomQuery#selectNode}.
 * 
 * The example above could have used this instead to achieve the same result:
 *
 *      childEls: [
 *          { name: 'bodyEl', itemId: 'bodyEl' }
 *      ]
 *
 * When using `select`, the property will be an instance of {@link Ext.CompositeElement}. In
 * all other cases, the property will be an {@link Ext.Element} or `null` if not found.
 *
 * Care should be taken when using `select` or `selectNode` to find child elements. The
 * following issues should be considered:
 * 
 * - Performance: using selectors can be slower than id lookup by a factor 10x or more.
 * - Over-selecting: selectors are applied after the DOM elements for all children have
 * been rendered, so selectors can match elements from child components (including nested
 * versions of the same component) accidentally.
 * 
 * This above issues are most important when using `select` since it returns multiple
 * elements.
 *
 * **IMPORTANT** 
 * Unlike a `renderTpl` where there is a single value for an instance, `childEls` are aggregated
 * up the class hierarchy so that they are effectively inherited. In other words, if a
 * class where to derive from `Ext.ux.SomeComponent` in the example above, it could also
 * have a `childEls` property in the same way as `Ext.ux.SomeComponent`.
 * 
 *      Ext.define('Ext.ux.AnotherComponent', {
 *          extend: 'Ext.ux.SomeComponent',
 *          
 *          childEls: [
 *              // 'bodyEl' is inherited
 *              'innerEl'
 *          ],
 *          
 *          renderTpl: [
 *              '&lt;div id="{id}-bodyEl"&gt;'
 *                  '&lt;div id="{id}-innerEl"&gt;&lt;/div&gt;'
 *              '&lt;/div&gt;'
 *          ],
 *          
 *          // ...
 *      });
 * 
 * The `renderTpl` contains both child elements and unites them in the desired markup, but
 * the `childEls` only contains the new child element. The {@link #applyChildEls} method
 * takes care of looking up all `childEls` for an instance and considers `childEls`
 * properties on all the super classes and mixins.

 *              }
 *          ]
 *      }
 *
 * The rendering of the above proceeds roughly like this:
 *
 *  - ContainerA's initComponent calls #render passing the `renderTo` property as the
 *    container argument.
 *  - `render` calls the `getRenderTree` method to get a complete {@link Ext.DomHelper} spec.
 *  - `getRenderTree` fires the "beforerender" event and calls the #beforeRender
 *    method. Its result is obtained by calling #getElConfig.
 *  - The #getElConfig method uses the `renderTpl` and its render data as the content
 *    of the `autoEl` described element.
 *  - The result of `getRenderTree` is passed to {@link Ext.DomHelper#append}.
 *  - The `renderTpl` contains calls to render things like docked items, container items
 *    and raw markup (such as the `html` or `tpl` config properties). These calls are to
 *    methods added to the {@link Ext.XTemplate} instance by #setupRenderTpl.
 *  - The #setupRenderTpl method adds methods such as `renderItems`, `renderContent`, etc.
 *    to the template. These are directed to "doRenderItems", "doRenderContent" etc..
 *  - The #setupRenderTpl calls traverse from components to their {@link Ext.layout.Layout}
 *    object.
 *  - When a container is rendered, it also has a `renderTpl`. This is processed when the
 *    `renderContainer` method is called in the component's `renderTpl`. This call goes to
 *    Ext.layout.container.Container#doRenderContainer. This method repeats this
 *    process for all components in the container.
 *  - After the top-most component's markup is generated and placed in to the DOM, the next
 *    step is to link elements to their components and finish calling the component methods
 *    `onRender` and `afterRender` as well as fire the corresponding events.
 *  - The first step in this is to call #finishRender. This method descends the
 *    component hierarchy and calls `onRender` and fires the `render` event. These calls
 *    are delivered top-down to approximate the timing of these calls/events from previous
 *    versions.
 *  - During the pass, the component's `el` is set. Likewise, the `renderSelectors` and
 *    `childEls` are applied to capture references to the component's elements.
 *  - These calls are also made on the {@link Ext.layout.container.Container} layout to
 *    capture its elements. Both of these classes use {@link Ext.util.ElementContainer} to
 *    handle `childEls` processing.
 *  - Once this is complete, a similar pass is made by calling #finishAfterRender.
 *    This call also descends the component hierarchy, but this time the calls are made in
 *    a bottom-up order to `afterRender`.

/**
 * Provides searching of Components within Ext.ComponentManager (globally) or a specific
 * Ext.container.Container on the document with a similar syntax to a CSS selector.
 *
 * Components can be retrieved by using their {@link Ext.Component xtype} with an optional . prefix
 *
 * - `component` or `.component`
 * - `gridpanel` or `.gridpanel`
 *
 * An itemId or id must be prefixed with a #
 *
 * - `#myContainer`
 *
 * Attributes must be wrapped in brackets
 *
 * - `component[autoScroll]`
 * - `panel[title="Test"]`
 *
 * Member expressions from candidate Components may be tested. If the expression returns a *truthy* value,
 * the candidate Component will be included in the query:
 *
 *     var disabledFields = myFormPanel.query("{isDisabled()}");
 *
 * Pseudo classes may be used to filter results in the same way as in {@link Ext.DomQuery DomQuery}:
 *
 *     // Function receives array and returns a filtered array.
 *     Ext.ComponentQuery.pseudos.invalid = function(items) {
 *         var i = 0, l = items.length, c, result = [];
 *         for (; i < l; i++) {
 *             if (!(c = items[i]).isValid()) {
 *                 result.push(c);
 *             }
 *         }
 *         return result;
 *     };
 *      
 *     var invalidFields = myFormPanel.query('field:invalid');
 *     if (invalidFields.length) {
 *         invalidFields[0].getEl().scrollIntoView(myFormPanel.body);
 *         for (var i = 0, l = invalidFields.length; i < l; i++) {
 *             invalidFields[i].getEl().frame("red");
 *         }
 *     }
 *
 * Default pseudos include:
 *
 * - not
 * - last
 *
 * Queries return an array of components.
 * Here are some example queries.
 *
 *     // retrieve all Ext.Panels in the document by xtype
 *     var panelsArray = Ext.ComponentQuery.query('panel');
 *
 *     // retrieve all Ext.Panels within the container with an id myCt
 *     var panelsWithinmyCt = Ext.ComponentQuery.query('#myCt panel');
 *
 *     // retrieve all direct children which are Ext.Panels within myCt
 *     var directChildPanel = Ext.ComponentQuery.query('#myCt > panel');
 *
 *     // retrieve all grids and trees
 *     var gridsAndTrees = Ext.ComponentQuery.query('gridpanel, treepanel');
 *
 * For easy access to queries based from a particular Container see the {@link Ext.container.Container#query},
 * {@link Ext.container.Container#down} and {@link Ext.container.Container#child} methods. Also see

/**
 * Handles mapping key events to handling functions for an element or a Component. One KeyMap can be used for multiple
 * actions.
 *
 * A KeyMap must be configured with a {@link #target} as an event source which may be an Element or a Component.
 *
 * If the target is an element, then the `keydown` event will trigger the invocation of {@link #binding}s.
 *
 * It is possible to configure the KeyMap with a custom {@link #eventName} to listen for. This may be useful when the
 * {@link #target} is a Component.
 *
 * The KeyMap's event handling requires that the first parameter passed is a key event. So if the Component's event
 * signature is different, specify a {@link #processEvent} configuration which accepts the event's parameters and
 * returns a key event.
 *
 * Functions specified in {@link #binding}s are called with this signature : `(String key, Ext.EventObject e)` (if the
 * match is a multi-key combination the callback will still be called only once). A KeyMap can also handle a string
 * representation of keys. By default KeyMap starts enabled.
 *
 * Usage:
 *
 *     // map one key by key code
 *     var map = new Ext.util.KeyMap({
 *         target: "my-element",
 *         key: 13, // or Ext.EventObject.ENTER
 *         fn: myHandler,
 *         scope: myObject
 *     });
 *
 *     // map multiple keys to one action by string
 *     var map = new Ext.util.KeyMap({
 *         target: "my-element",
 *         key: "a\r\n\t",
 *         fn: myHandler,
 *         scope: myObject
 *     });
 *
 *     // map multiple keys to multiple actions by strings and array of codes
 *     var map = new Ext.util.KeyMap({
 *         target: "my-element",
 *         binding: [{
 *             key: [10,13],
 *             fn: function(){ alert("Return was pressed"); }
 *         }, {
 *             key: "abc",
 *             fn: function(){ alert('a, b or c was pressed'); }
 *         }, {
 *             key: "\t",
 *             ctrl:true,
 *             shift:true,
 *             fn: function(){ alert('Control + shift + tab was pressed.'); }
 *         }]
 *     });
 *
 * Since 4.1.0, KeyMaps can bind to Components and process key-based events fired by Components.
 *
 * To bind to a Component, use the single parameter form of constructor:
 *
 *     var map = new Ext.util.KeyMap({
 *         target: myGridView,
 *         eventName: 'itemkeydown',
 *         processEvent: function(view, record, node, index, event) {
 *
 *             // Load the event with the extra information needed by the mappings
 *             event.view = view;
 *             event.store = view.getStore();
 *             event.record = record;
 *             event.index = index;
 *             return event;
 *         },
 *         binding: {
 *             key: Ext.EventObject.DELETE,
 *             fn: function(keyCode, e) {
 *                 e.store.remove(e.record);
 *
 *                 // Attempt to select the record that's now in its place
 *                 e.view.getSelectionModel().select(e,index);
 *                 e.view.el.focus();
 *             }
 *         }

/**
 * @class Ext.app.Controller
 *
 * Controllers are the glue that binds an application together. All they really do is listen for events (usually from
 * views) and take some action. Here's how we might create a Controller to manage Users:
 *
 *     Ext.define('MyApp.controller.Users', {
 *         extend: 'Ext.app.Controller',
 *
 *         init: function() {
 *             console.log('Initialized Users! This happens before the Application launch function is called');
 *         }
 *     });
 *
 * The init function is a special method that is called when your application boots. It is called before the
 * {@link Ext.app.Application Application}'s launch function is executed so gives a hook point to run any code before
 * your Viewport is created.
 *
 * The init function is a great place to set up how your controller interacts with the view, and is usually used in
 * conjunction with another Controller function - {@link Ext.app.Controller#control control}. The control function
 * makes it easy to listen to events on your view classes and take some action with a handler function. Let's update
 * our Users controller to tell us when the panel is rendered:
 *
 *     Ext.define('MyApp.controller.Users', {
 *         extend: 'Ext.app.Controller',
 *
 *         init: function() {
 *             this.control({
 *                 'viewport > panel': {
 *                     render: this.onPanelRendered
 *                 }
 *             });
 *         },
 *
 *         onPanelRendered: function() {
 *             console.log('The panel was rendered');
 *         }
 *     });
 *
 * We've updated the init function to use this.control to set up listeners on views in our application. The control
 * function uses the new ComponentQuery engine to quickly and easily get references to components on the page. If you
 * are not familiar with ComponentQuery yet, be sure to check out the {@link Ext.ComponentQuery documentation}. In brief though,
 * it allows us to pass a CSS-like selector that will find every matching component on the page.
 *
 * In our init function above we supplied 'viewport > panel', which translates to "find me every Panel that is a direct
 * child of a Viewport". We then supplied an object that maps event names (just 'render' in this case) to handler
 * functions. The overall effect is that whenever any component that matches our selector fires a 'render' event, our
 * onPanelRendered function is called.
 *
 * <u>Using refs</u>
 *
 * One of the most useful parts of Controllers is the new ref system. These use the new {@link Ext.ComponentQuery} to
 * make it really easy to get references to Views on your page. Let's look at an example of this now:
 *
 *     Ext.define('MyApp.controller.Users', {
 *         extend: 'Ext.app.Controller',
 *
 *         refs: [
 *             {
 *                 ref: 'list',
 *                 selector: 'grid'
 *             }
 *         ],
 *
 *         init: function() {
 *             this.control({
 *                 'button': {
 *                     click: this.refreshGrid
 *                 }
 *             });
 *         },
 *
 *         refreshGrid: function() {
 *             this.getList().store.load();
 *         }
 *     });
 *
 * This example assumes the existence of a {@link Ext.grid.Panel Grid} on the page, which contains a single button to
 * refresh the Grid when clicked. In our refs array, we set up a reference to the grid. There are two parts to this -
 * the 'selector', which is a {@link Ext.ComponentQuery ComponentQuery} selector which finds any grid on the page and
 * assigns it to the reference 'list'.
 *
 * By giving the reference a name, we get a number of things for free. The first is the getList function that we use in
 * the refreshGrid method above. This is generated automatically by the Controller based on the name of our ref, which
 * was capitalized and prepended with get to go from 'list' to 'getList'.
 *
 * The way this works is that the first time getList is called by your code, the ComponentQuery selector is run and the
 * first component that matches the selector ('grid' in this case) will be returned. All future calls to getList will
 * use a cached reference to that grid. Usually it is advised to use a specific ComponentQuery selector that will only
 * match a single View in your application (in the case above our selector will match any grid on the page).
 *
 * Bringing it all together, our init function is called when the application boots, at which time we call this.control
 * to listen to any click on a {@link Ext.button.Button button} and call our refreshGrid function (again, this will
 * match any button on the page so we advise a more specific selector than just 'button', but have left it this way for
 * simplicity). When the button is clicked we use out getList function to refresh the grid.
 *
 * You can create any number of refs and control any number of components this way, simply adding more functions to
 * your Controller as you go. For an example of real-world usage of Controllers see the Feed Viewer example in the
 * examples/app/feed-viewer folder in the SDK download.
 *
 * <u>Generated getter methods</u>
 *
 * Refs aren't the only thing that generate convenient getter methods. Controllers often have to deal with Models and
 * Stores so the framework offers a couple of easy ways to get access to those too. Let's look at another example:
 *
 *     Ext.define('MyApp.controller.Users', {
 *         extend: 'Ext.app.Controller',
 *
 *         models: ['User'],
 *         stores: ['AllUsers', 'AdminUsers'],
 *
 *         init: function() {
 *             var User = this.getUserModel(),
 *                 allUsers = this.getAllUsersStore();
 *
 *             var ed = new User({name: 'Ed'});
 *             allUsers.add(ed);
 *         }
 *     });
 *
 * By specifying Models and Stores that the Controller cares about, it again dynamically loads them from the appropriate
 * locations (app/model/User.js, app/store/AllUsers.js and app/store/AdminUsers.js in this case) and creates getter
 * functions for them all. The example above will create a new User model instance and add it to the AllUsers Store.
 * Of course, you could do anything in this function but in this case we just did something simple to demonstrate the
 * functionality.

/**
 * @author Ed Spencer
 * @class Ext.ModelManager

The ModelManager keeps track of all {@link Ext.data.Model} types defined in your application.

__Creating Model Instances__

Model instances can be created by using the {@link Ext#create Ext.create} method. Ext.create replaces
the deprecated {@link #create Ext.ModelManager.create} method. It is also possible to create a model instance
this by using the Model type directly. The following 3 snippets are equivalent:

    Ext.define('User', {
        extend: 'Ext.data.Model',
        fields: ['first', 'last']
    });

    // method 1, create using Ext.create (recommended)
    Ext.create('User', {
        first: 'Ed',
        last: 'Spencer'
    });

    // method 2, create through the manager (deprecated)
    Ext.ModelManager.create({
        first: 'Ed',
        last: 'Spencer'
    }, 'User');

    // method 3, create on the type directly
    new User({
        first: 'Ed',
        last: 'Spencer'
    });

__Accessing Model Types__

A reference to a Model type can be obtained by using the {@link #getModel} function. Since models types
are normal classes, you can access the type directly. The following snippets are equivalent:

    Ext.define('User', {
        extend: 'Ext.data.Model',
        fields: ['first', 'last']
    });

    // method 1, access model type through the manager

 * of this class.</p>
 * <p>Developers may add their own application-specific data types to this class. Definition names must be UPPERCASE.
 * each type definition must contain three properties:</p>
 * <div class="mdetail-params"><ul>
 * <li><code>convert</code> : <i>Function</i><div class="sub-desc">A function to convert raw data values from a data block into the data
 * to be stored in the Field. The function is passed the collowing parameters:
 * <div class="mdetail-params"><ul>
 * <li><b>v</b> : Mixed<div class="sub-desc">The data value as read by the Reader, if undefined will use
 * the configured <tt>{@link Ext.data.Field#defaultValue defaultValue}</tt>.</div></li>
 * <li><b>rec</b> : Mixed<div class="sub-desc">The data object containing the row as read by the Reader.
 * Depending on the Reader type, this could be an Array ({@link Ext.data.reader.Array ArrayReader}), an object

 * <li><code>type</code> : <i>String</i> <div class="sub-desc">A textual data type name.</div></li>

 * <p>For example, to create a VELatLong field (See the Microsoft Bing Mapping API) containing the latitude/longitude value of a datapoint on a map from a JsonReader data block
 * which contained the properties <code>lat</code> and <code>long</code>, you would define a new data type like this:</p>
 *<pre><code>

/**
 * @author Ed Spencer
 *
 * Fields are used to define what a Model is. They aren't instantiated directly - instead, when we create a class that
 * extends {@link Ext.data.Model}, it will automatically create a Field instance for each field configured in a {@link
 * Ext.data.Model Model}. For example, we might set up a model like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         fields: [
 *             'name', 'email',
 *             {name: 'age', type: 'int'},
 *             {name: 'gender', type: 'string', defaultValue: 'Unknown'}
 *         ]
 *     });
 *
 * Four fields will have been created for the User Model - name, email, age and gender. Note that we specified a couple
 * of different formats here; if we only pass in the string name of the field (as with name and email), the field is set
 * up with the 'auto' type. It's as if we'd done this instead:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         fields: [
 *             {name: 'name', type: 'auto'},
 *             {name: 'email', type: 'auto'},
 *             {name: 'age', type: 'int'},
 *             {name: 'gender', type: 'string', defaultValue: 'Unknown'}
 *         ]
 *     });
 *
 * # Types and conversion
 *
 * The {@link #type} is important - it's used to automatically convert data passed to the field into the correct format.
 * In our example above, the name and email fields used the 'auto' type and will just accept anything that is passed
 * into them. The 'age' field had an 'int' type however, so if we passed 25.4 this would be rounded to 25.
 *
 * Sometimes a simple type isn't enough, or we want to perform some processing when we load a Field's data. We can do
 * this using a {@link #convert} function. Here, we're going to create a new field based on another:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         fields: [
 *             'name', 'email',
 *             {name: 'age', type: 'int'},
 *             {name: 'gender', type: 'string', defaultValue: 'Unknown'},
 *
 *             {
 *                 name: 'firstName',
 *                 convert: function(value, record) {
 *                     var fullName  = record.get('name'),
 *                         splits    = fullName.split(" "),
 *                         firstName = splits[0];
 *
 *                     return firstName;
 *                 }
 *             }
 *         ]
 *     });
 *
 * Now when we create a new User, the firstName is populated automatically based on the name:
 *
 *     var ed = Ext.create('User', {name: 'Ed Spencer'});
 *
 *     console.log(ed.get('firstName')); //logs 'Ed', based on our convert function
 *
 * In fact, if we log out all of the data inside ed, we'll see this:
 *
 *     console.log(ed.data);
 *
 *     //outputs this:
 *     {
 *         age: 0,
 *         email: "",
 *         firstName: "Ed",
 *         gender: "Unknown",
 *         name: "Ed Spencer"
 *     }
 *
 * The age field has been given a default of zero because we made it an int type. As an auto field, email has defaulted
 * to an empty string. When we registered the User model we set gender's {@link #defaultValue} to 'Unknown' so we see
 * that now. Let's correct that and satisfy ourselves that the types work as we expect:
 *
 *     ed.set('gender', 'Male');
 *     ed.get('gender'); //returns 'Male'
 *
 *     ed.set('age', 25.4);
 *     ed.get('age'); //returns 25 - we wanted an int, not a float, so no decimal places allowed

/**
 * @class Ext.Ajax

 * @markdown

A singleton instance of an {@link Ext.data.Connection}. This class
is used to communicate with your server side code. It can be used as follows:

    Ext.Ajax.request({
        url: 'page.php',
        params: {
            id: 1
        },

            var text = response.responseText;
            // process server response here
        }
    });

Default options for all requests can be set by changing a property on the Ext.Ajax class:

    Ext.Ajax.timeout = 60000; // 60 seconds

Any options specified in the request method for the Ajax request will override any
defaults set on the Ext.Ajax class. In the code sample below, the timeout for the
request will be 60 seconds.

    Ext.Ajax.timeout = 120000; // 120 seconds
    Ext.Ajax.request({
        url: 'page.aspx',
        timeout: 60000
    });

In general, this class will be used for all Ajax requests in your application.
The main reason for creating a separate {@link Ext.data.Connection} is for a
series of requests that share common settings that are different to all other
requests in the application.

     *          Ext.create('Ext.form.field.Number', {
     *              fieldLabel: 'Num'
     *          })
     *      ]
     *
     * But by using `xtype`, the above becomes:
     *
     *      items: [
     *          {
     *              xtype: 'textfield',
     *              fieldLabel: 'Foo'
     *          },
     *          {
     *              xtype: 'textfield',
     *              fieldLabel: 'Bar'
     *          },
     *          {
     *              xtype: 'numberfield',
     *              fieldLabel: 'Num'
     *          }
     *      ]
     *
     * When the `xtype` is common to many items, {@link Ext.container.AbstractContainer#defaultType}
     * is another way to specify the `xtype` for all items that don't have an explicit `xtype`:
     *
     *      defaultType: 'textfield',
     *      items: [
     *          { fieldLabel: 'Foo' },
     *          { fieldLabel: 'Bar' },
     *          { fieldLabel: 'Num', xtype: 'numberfield' }
     *      ]
     *
     * Each member of the `items` array is now just a "configuration object". These objects
     * are used to create and configure component instances. A configuration object can be
     * manually used to instantiate a component using {@link Ext#widget}:
     *
     *      var text1 = Ext.create('Ext.form.field.Text', {
     *          fieldLabel: 'Foo'
     *      });
     *
     *      // or alternatively:
     *
     *      var text1 = Ext.widget({
     *          xtype: 'textfield',
     *          fieldLabel: 'Foo'
     *      });
     *
     * This conversion of configuration objects into instantiated components is done when
     * a container is created as part of its {Ext.container.AbstractContainer#initComponent}
     * process. As part of the same process, the `items` array is converted from its raw
     * array form into a {@link Ext.util.MixedCollection} instance.
     *
     * You can define your own `xtype` on a custom {@link Ext.Component component} by specifying
     * the `xtype` property in {@link Ext#define}. For example:
     *
     *     Ext.define('MyApp.PressMeButton', {
     *         extend: 'Ext.button.Button',
     *         xtype: 'pressmebutton',
     *         text: 'Press Me'
     *     });
     *
     * Care should be taken when naming an `xtype` in a custom component because there is
     * a single, shared scope for all xtypes. Third part components should consider using
     * a prefix to avoid collisions.
     *
     *     Ext.define('Foo.form.CoolButton', {
     *         extend: 'Ext.button.Button',
     *         xtype: 'ux-coolbutton',
     *         text: 'Cool!'
