/**A rudimentary mechanism for measuring code execution speed is provided, in the form of the Profile function. For any
*profiling to be performed, Profile.enabled must be true. If the provided codeBlock is idempotent, you may choose
*to pass a larger loopCount value; this will result in the code being executed several times, thus theoretically increasing
*the profiling accuracy. labelString may contain one or more / characters, which will provide basic grouping (but not
*aggregation) in the report.
*Depending on the value of the DEBUG query string parameter, profiling is automatically set to one of four detail levels:
*The data recorded against each measurement unit (either each Profile call, or each second-level Profile call, depending
*on the debug level) comprises
* - the total time spent inside this code
* - the total time spent inside this code directly (not counting code executed inside nested Profile calls),
* - the number of times this code was called
* - the minimum, maximum, and average time spent inside individual executions of this code
* These values are all calculated after compensating for loopCount values. If the code was executed additional times for loopCount
* processing, the "claimed" and "actual" execution counts are shown in square brackets, next to the label.
* Finally, the profile report also includes "Total Time Profiled" and "Total Junk Time" values. These represent the total time
* spent inside any call to Profile, for the "claimed" and "actual" loops, respectively. Thus, "Total Time Profiled" can diverge
* measurably from the time it actually takes to complete the request; it is intended to represent the time it would take to complete the
* same request at a reduced debug level. (Note however that it is only indicative; profiling itself introduces substantial overhead.)
* 
* 0  - No profiling: the codeBlock is executed once, and its value returned.
* 1 - Basic profiling: the codeBlock is executed once, its execution time is recorded, and its value is returned.
* 2 -  Extended profiling: the codeBlock is executed once, recording both its direct
* execution time, and separately recording the time spent inside each second-level
* Profile call. This results in a substantial increase in the amount of profiling data
* generated.
* 3 - Full profiling: as per Extended profiling, but the codeBlock is executed loopCount times. The return value is the result of the last (that is, the
* loopCountth) execution of codeBlock.

 * <pre><code>
Date.patterns = {

/*
 * Filters are essentially just functions that reformat the value they
 * are given to some other (presumably better) format. They are used in
 * two ways: as simple calls within an error message substitution; and
 * as wrappers for form fields, to format the contained data more
 * consistently. 
 *
 * To define a new filter, just add a function to the Validator.Filter
 * object. Filters should take a single parameter (the type of which may
 * vary), and return a string. 
 *
 * In error message substitutions, filters can be invoked through the
 * use of the colon inside a substitution field. Multiple filters are
 * evaluated right-to-left. Note that if you're trying to do anything
 * "real", you're probably better off just using a method to build it
 * instead.
 *
 * Filters are also employed in the form field pipeline, allowing the
 * auto-correction of user-supplied data. Optionally, an 'Inverse'
 * filter may also be defined, thus causing the format in which the data
 * is stored to differ from that in which it is presented. 
 *
 * The canonical example of a bidirectional filter is 'money'; the
 * "forward" filter converts "12345.6" to "$12,345.60", while the
 * inverse filter correspondingly converts "$76,543.20" to "76543.2".
 *
 * When combining filters and validation, note that all field
 * validations are applied to the inverse-filtered value, where
 * applicable.

/**
 * @class Ext.DomHelper
 * Utility class for working with DOM and/or Templates. It transparently supports using HTML fragments or DOM.<br>
 * This is an example, where an unordered list with 5 children items is appended to an existing element with id 'my-div':<br>
 <pre><code>
var dh = Ext.DomHelper;
var list = dh.append('my-div', {
    id: 'my-ul', tag: 'ul', cls: 'my-list', children: [
        {tag: 'li', id: 'item0', html: 'List Item 0'},
        {tag: 'li', id: 'item1', html: 'List Item 1'},
        {tag: 'li', id: 'item2', html: 'List Item 2'},
        {tag: 'li', id: 'item3', html: 'List Item 3'},
        {tag: 'li', id: 'item4', html: 'List Item 4'}
    ]
});
 </code></pre>
 * <p>Element creation specification parameters in this class may also be passed as an Array of
 * specification objects. This can be used to insert multiple sibling nodes into an existing
 * container very efficiently. For example, to add more list items to the example above:<pre><code>
dh.append('my-ul', [
    {tag: 'li', id: 'item5', html: 'List Item 5'},
    {tag: 'li', id: 'item6', html: 'List Item 6'} ]);
</code></pre></p>
 * <p>Element creation specification parameters may also be strings. If {@link useDom} is false, then the string is used
 * as innerHTML. If {@link useDom} is true, a string specification results in the creation of a text node.</p>
 * For more information and examples, see <a href="http://www.jackslocum.com/blog/2006/10/06/domhelper-create-elements-using-dom-html-fragments-or-templates/">the original blog post</a>.

/**
 * @class Ext.DomQuery
Provides high performance selector/xpath processing by compiling queries into reusable functions. New pseudo classes and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in).
<p>
DomQuery supports most of the <a href="http://www.w3.org/TR/2005/WD-css3-selectors-20051215/#selectors">CSS3 selectors spec</a>, along with some custom selectors and basic XPath.</p>

<p>
All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example "div.foo:nth-child(odd)[@foo=bar].bar:first" would be a perfectly valid selector. Node filters are processed in the order in which they appear, which allows you to optimize your queries for your document structure.
</p>
<h4>Element Selectors:</h4>
<ul class="list">
    <li> <b>*</b> any element</li>
    <li> <b>E</b> an element with the tag E</li>
    <li> <b>E F</b> All descendent elements of E that have the tag F</li>
    <li> <b>E > F</b> or <b>E/F</b> all direct children elements of E that have the tag F</li>
    <li> <b>E + F</b> all elements with the tag F that are immediately preceded by an element with the tag E</li>
    <li> <b>E ~ F</b> all elements with the tag F that are preceded by a sibling element with the tag E</li>
</ul>
<h4>Attribute Selectors:</h4>
<p>The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.</p>
<ul class="list">
    <li> <b>E[foo]</b> has an attribute "foo"</li>
    <li> <b>E[foo=bar]</b> has an attribute "foo" that equals "bar"</li>
    <li> <b>E[foo^=bar]</b> has an attribute "foo" that starts with "bar"</li>
    <li> <b>E[foo$=bar]</b> has an attribute "foo" that ends with "bar"</li>
    <li> <b>E[foo*=bar]</b> has an attribute "foo" that contains the substring "bar"</li>
    <li> <b>E[foo%=2]</b> has an attribute "foo" that is evenly divisible by 2</li>
    <li> <b>E[foo!=bar]</b> has an attribute "foo" that does not equal "bar"</li>
</ul>
<h4>Pseudo Classes:</h4>
<ul class="list">
    <li> <b>E:first-child</b> E is the first child of its parent</li>
    <li> <b>E:last-child</b> E is the last child of its parent</li>
    <li> <b>E:nth-child(<i>n</i>)</b> E is the <i>n</i>th child of its parent (1 based as per the spec)</li>
    <li> <b>E:nth-child(odd)</b> E is an odd child of its parent</li>
    <li> <b>E:nth-child(even)</b> E is an even child of its parent</li>
    <li> <b>E:only-child</b> E is the only child of its parent</li>
    <li> <b>E:checked</b> E is an element that is has a checked attribute that is true (e.g. a radio or checkbox) </li>
    <li> <b>E:first</b> the first E in the resultset</li>
    <li> <b>E:last</b> the last E in the resultset</li>
    <li> <b>E:nth(<i>n</i>)</b> the <i>n</i>th E in the resultset (1 based)</li>
    <li> <b>E:odd</b> shortcut for :nth-child(odd)</li>
    <li> <b>E:even</b> shortcut for :nth-child(even)</li>
    <li> <b>E:contains(foo)</b> E's innerHTML contains the substring "foo"</li>
    <li> <b>E:nodeValue(foo)</b> E contains a textNode with a nodeValue that equals "foo"</li>
    <li> <b>E:not(S)</b> an E element that does not match simple selector S</li>
    <li> <b>E:has(S)</b> an E element that has a descendent that matches simple selector S</li>
    <li> <b>E:next(S)</b> an E element whose next sibling matches simple selector S</li>
    <li> <b>E:prev(S)</b> an E element whose previous sibling matches simple selector S</li>
</ul>
<h4>CSS Value Selectors:</h4>
<ul class="list">

 * @class Ext.Element
 * Represents an Element in the DOM.<br><br>
 * Usage:<br>
<pre><code>
// by id
var el = Ext.get("my-div");

// by DOM element reference
var el = Ext.get(myDivElement);
</code></pre>
 * <b>Animations</b><br />
 * Many of the functions for manipulating an element have an optional "animate" parameter. The animate parameter
 * should either be a boolean (true) or an object literal with animation options. Note that the supported Element animation
 * options are a subset of the {@link Ext.Fx} animation options specific to Fx effects.  The Element animation options are:
<pre>
Option    Default   Description
--------- --------  ---------------------------------------------
duration  .35       The duration of the animation in seconds
easing    easeOut   The easing method
callback  none      A function to execute when the anim completes
scope     this      The scope (this) of the callback function
</pre>
* Also, the Anim object being used for the animation will be set on your options object as "anim", which allows you to stop or
* manipulate the animation. Here's an example:
<pre><code>
var el = Ext.get("my-div");

// no animation
el.setWidth(100);

// default animation
el.setWidth(100, true);

// animation with some options set
el.setWidth(100, {
    duration: 1,
    callback: this.foo,
    scope: this
});

// using the "anim" property to get the Anim object
var opt = {
    duration: 1,
    callback: this.foo,
    scope: this
};
el.setWidth(100, opt);
...
if(opt.anim.isAnimated()){
    opt.anim.stop();
}
</code></pre>
* <b> Composite (Collections of) Elements</b><br />
 * For working with collections of Elements, see {@link Ext.CompositeElement}
 * @constructor Create a new Element directly.
 * @param {String/HTMLElement} element
 * @param {Boolean} forceNew (optional) By default the constructor checks to see if there is already an instance of this element in the cache and if there is it returns the same instance. This will skip that check (useful for extending this class).

     * Aligns this element with another element relative to the specified anchor points. If the other element is the

     * <ul>
     *   <li><b>Blank</b>: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").</li>
     *   <li><b>One anchor (deprecated)</b>: The passed anchor position is used as the target element's anchor point.
     *       The element being aligned will position its top-left corner (tl) to that point.  <i>This method has been
     *       deprecated in favor of the newer two anchor syntax below</i>.</li>
     *   <li><b>Two anchors</b>: If two values from the table below are passed separated by a dash, the first value is used as the
     *       element's anchor point, and the second value is used as the target's anchor point.</li>
     * </ul>
     * In addition to the anchor points, the position parameter also supports the "?" character.  If "?" is passed at the end of
     * the position string, the element will attempt to align as specified, but the position will be adjusted to constrain to
     * the viewport if necessary.  Note that the element being aligned might be swapped to align to a different position than
     * that specified in order to enforce the viewport constraints.

Value  Description
-----  -----------------------------
tl     The top left corner (default)
t      The center of the top edge

r      The center of the right edge
bl     The bottom left corner
b      The center of the bottom edge
br     The bottom right corner

/**
 * @class Ext.Fx
 * <p>A class to provide basic animation and visual effects support.  <b>Note:</b> This class is automatically applied
 * to the {@link Ext.Element} interface when included, so all effects calls should be performed via Element.
 * Conversely, since the effects are not actually defined in Element, Ext.Fx <b>must</b> be included in order for the 
 * Element effects to work.</p><br/>
 *
 * <p>It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that
 * they return the Element object itself as the method return value, it is not always possible to mix the two in a single
 * method chain.  The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced.
 * Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately.  For this reason,
 * while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the
 * expected results and should be done with care.</p><br/>
 *
 * <p>Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element
 * that will serve as either the start or end point of the animation.  Following are all of the supported anchor positions:</p>
<pre>
Value  Description
-----  -----------------------------
tl     The top left corner
t      The center of the top edge
tr     The top right corner
l      The center of the left edge
r      The center of the right edge
bl     The bottom left corner
b      The center of the bottom edge
br     The bottom right corner
</pre>
 * <b>Although some Fx methods accept specific custom config parameters, the ones shown in the Config Options section
 * below are common options that can be passed to any Fx method.</b>
 * 
 * @cfg {Function} callback A function called when the effect is finished.  Note that effects are queued internally by the
 * Fx class, so do not need to use the callback parameter to specify another effect -- effects can simply be chained together
 * and called in sequence (e.g., el.slideIn().highlight();).  The callback is intended for any additional code that should
 * run once a particular effect has completed.
 * @cfg {Object} scope The scope of the effect function
 * @cfg {String} easing A valid Easing value for the effect
 * @cfg {String} afterCls A css class to apply after the effect
 * @cfg {Number} duration The length of time (in seconds) that the effect should last
 * @cfg {Boolean} remove Whether the Element should be removed from the DOM and destroyed after the effect finishes
 * @cfg {Boolean} useDisplay Whether to use the <i>display</i> CSS property instead of <i>visibility</i> when hiding Elements (only applies to 
 * effects that end with the element being visually hidden, ignored otherwise)
 * @cfg {String/Object/Function} afterStyle A style specification string, e.g. "width:100px", or an object in the form {width:"100px"}, or
 * a function which returns such a specification that will be applied to the Element after the effect finishes
 * @cfg {Boolean} block Whether the effect should block other effects from queueing while it runs
 * @cfg {Boolean} concurrent Whether to allow subsequently-queued effects to run at the same time as the current effect, or to ensure that they run in sequence
 * @cfg {Boolean} stopFx Whether subsequent effects should be stopped and removed after the current effect finishes

 * globally available on the Date object.  Feel free to add or remove patterns as needed in your code.
 * <pre><code>
Date.patterns = {

* @class Ext.XTemplate
* @extends Ext.Template
* <p>A template class that supports advanced functionality like autofilling arrays, conditional processing with
* basic comparison operators, sub-templates, basic math function support, special built-in template variables,
* inline code execution and more.  XTemplate also provides the templating mechanism built into {@link Ext.DataView}.</p>
* <p>XTemplate supports many special tags and built-in operators that aren't defined as part of the API, but are
* supported in the templates that can be created.  The following examples demonstrate all of the supported features.
* This is the data object used for reference in each code example:</p>
* <pre><code>
var data = {
    name: 'Jack Slocum',
    title: 'Lead Developer',
    company: 'Ext JS, LLC',
    email: 'jack@extjs.com',
    address: '4 Red Bulls Drive',
    city: 'Cleveland',
    state: 'Ohio',
    zip: '44102',
    drinks: ['Red Bull', 'Coffee', 'Water'],
    kids: [{
        name: 'Sara Grace',
        age:3
    },{
        name: 'Zachary',
        age:2
    },{
        name: 'John James',
        age:0
    }]
};
</code></pre>
* <p><b>Auto filling of arrays and scope switching</b><br/>Using the <tt>tpl</tt> tag and the <tt>for</tt> operator,
* you can switch to the scope of the object specified by <tt>for</tt> and access its members to populate the template.
* If the variable in <tt>for</tt> is an array, it will auto-fill, repeating the template block inside the <tt>tpl</tt>
* tag for each item in the array:</p>
* <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Title: {title}&lt;/p>',
    '&lt;p>Company: {company}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;p>{name}&lt;/p>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
</code></pre>
* <p><b>Access to parent object from within sub-template scope</b><br/>When processing a sub-template, for example while
* looping through a child array, you can access the parent object's members via the <tt>parent</tt> object:</p>
* <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;tpl if="age &amp;gt; 1">',  // <-- Note that the &gt; is encoded
            '&lt;p>{name}&lt;/p>',
            '&lt;p>Dad: {parent.name}&lt;/p>',
        '&lt;/tpl>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
</code></pre>
* <p><b>Array item index and basic math support</b> <br/>While processing an array, the special variable <tt>{#}</tt>
* will provide the current array index + 1 (starts at 1, not 0). Templates also support the basic math operators
* + - * and / that can be applied directly on numeric data values:</p>
* <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;tpl if="age &amp;gt; 1">',  // <-- Note that the &gt; is encoded
            '&lt;p>{#}: {name}&lt;/p>',  // <-- Auto-number each item
            '&lt;p>In 5 Years: {age+5}&lt;/p>',  // <-- Basic math
            '&lt;p>Dad: {parent.name}&lt;/p>',
        '&lt;/tpl>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
</code></pre>
* <p><b>Auto-rendering of flat arrays</b> <br/>Flat arrays that contain values (and not objects) can be auto-rendered
* using the special <tt>{.}</tt> variable inside a loop.  This variable will represent the value of
* the array at the current index:</p>
* <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>{name}\'s favorite beverages:&lt;/p>',
    '&lt;tpl for="drinks">',
       '&lt;div> - {.}&lt;/div>',
    '&lt;/tpl>'
);
tpl.overwrite(panel.body, data);
</code></pre>
* <p><b>Basic conditional logic</b> <br/>Using the <tt>tpl</tt> tag and the <tt>if</tt>
* operator you can provide conditional checks for deciding whether or not to render specific parts of the template.
* Note that there is no <tt>else</tt> operator &mdash; if needed, you should use two opposite <tt>if</tt> statements.
* Properly-encoded attributes are required as seen in the following example:</p>
* <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;tpl if="age &amp;gt; 1">',  // <-- Note that the &gt; is encoded
            '&lt;p>{name}&lt;/p>',
        '&lt;/tpl>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
</code></pre>
* <p><b>Ability to execute arbitrary inline code</b> <br/>In an XTemplate, anything between {[ ... ]}  is considered
* code to be executed in the scope of the template. There are some special variables available in that code:
* <ul>
* <li><b><tt>values</tt></b>: The values in the current scope. If you are using scope changing sub-templates, you
* can change what <tt>values</tt> is.</li>
* <li><b><tt>parent</tt></b>: The scope (values) of the ancestor template.</li>
* <li><b><tt>xindex</tt></b>: If you are in a looping template, the index of the loop you are in (1-based).</li>
* <li><b><tt>xcount</tt></b>: If you are in a looping template, the total length of the array you are looping.</li>
* <li><b><tt>fm</tt></b>: An alias for <tt>Ext.util.Format</tt>.</li>
* </ul>
* This example demonstrates basic row striping using an inline code block and the <tt>xindex</tt> variable:</p>
* <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Company: {[values.company.toUpperCase() + ', ' + values.title]}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
       '&lt;div class="{[xindex % 2 === 0 ? "even" : "odd"]}">',
        '{name}',
        '&lt;/div>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
</code></pre>
* <p><b>Template member functions</b> <br/>One or more member functions can be defined directly on the config
* object passed into the XTemplate constructor for more complex processing:</p>
* <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;tpl if="this.isGirl(name)">',
            '&lt;p>Girl: {name} - {age}&lt;/p>',
        '&lt;/tpl>',
        '&lt;tpl if="this.isGirl(name) == false">',
            '&lt;p>Boy: {name} - {age}&lt;/p>',
        '&lt;/tpl>',
        '&lt;tpl if="this.isBaby(age)">',
            '&lt;p>{name} is a baby!&lt;/p>',
        '&lt;/tpl>',
    '&lt;/tpl>&lt;/p>', {
     isGirl: function(name){
         return name == 'Sara Grace';
     },
     isBaby: function(age){
        return age < 1;
     }
});
tpl.overwrite(panel.body, data);

 @class Ext.util.ClickRepeater
 @extends Ext.util.Observable

 A wrapper class which can be applied to any element. Fires a "click" event while the
 mouse is pressed. The interval between firings may be specified in the config but
 defaults to 20 milliseconds.

 Optionally, a CSS class may be applied to the element during the time it is pressed.

 @cfg {Mixed} el The element to act as a button.
 @cfg {Number} delay The initial delay before the repeating event begins firing.
 Similar to an autorepeat key delay.
 @cfg {Number} interval The interval between firings of the "click" event. Default 20 ms.
 @cfg {String} pressClass A CSS class name to be applied to the element while pressed.
 @cfg {Boolean} accelerate True if autorepeating should start slowly and accelerate.
           "interval" and "delay" are ignored.
 @cfg {Boolean} preventDefault True to prevent the default click event
 @cfg {Boolean} stopDefault True to stop the default click event

 <pre><code>

 * Up to three html elements can be associated with a DragDrop instance:
 * <ul>
 * <li>linked element: the element that is passed into the constructor.
 * This is the element which defines the boundaries for interaction with
 * other DragDrop objects.</li>
 * <li>handle element(s): The drag operation only occurs if the element that
 * was clicked matches a handle element.  By default this is the linked
 * element, but there are times that you will want only a portion of the
 * linked element to initiate the drag operation, and the setHandleElId()
 * method provides a way to define this.</li>
 * <li>drag element: this represents the element that would be moved along
 * with the cursor during a drag operation.  By default, this is the linked
 * element itself as in {@link Ext.dd.DD}.  setDragElId() lets you define
 * a separate element that would be moved, as in {@link Ext.dd.DDProxy}.
 * </li>
 * </ul>
 * This class should not be instantiated until the onload event to ensure that
 * the associated elements are available.

 * other DragDrop obj in the "group1" group:
 * <pre>
 *  dd = new Ext.dd.DragDrop("div1", "group1");
 * </pre>

 * actually happen if you were to run the code above.  Normally you would
 * override this class or one of the default implementations, but you can
 * also override the methods you want on an instance of the class...

 * @class Ext.data.JsonStore

 * Small helper class to make creating Stores for remotely-loaded JSON data easier. JsonStore is pre-configured 
 * with a built-in {@link Ext.data.HttpProxy} and {@link Ext.data.JsonReader}.  If you require some other proxy/reader
 * combination then you'll have to create a basic {@link Ext.data.Store} configured as needed.<br/>
<pre><code>
var store = new Ext.data.JsonStore({
    url: 'get-images.php',
    root: 'images',
    fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
});
</code></pre>
 * This would consume a returned object of the form:
<pre><code>
{
    images: [
        {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)},
        {name: 'Image Two', url:'/GetImage.php?id=2', size:43.2, lastmod: new Date(2007, 10, 30)}
    ]
}
</code></pre>
 * An object literal of this form could also be used as the {@link #data} config option.
 * <b>Note: Although they are not listed, this class inherits all of the config options of Store,
 * JsonReader.</b>
 * @cfg {String} url  The URL from which to load data through an HttpProxy. Either this
 * option, or the {@link #data} option must be specified.
 * @cfg {Object} data  A data object readable by this object's JsonReader. Either this
 * option, or the {@link #url} option must be specified.
 * @cfg {Array} fields  Either an Array of field definition objects as passed to
 * {@link Ext.data.Record#create}, or a {@link Ext.data.Record Record} constructor created using {@link Ext.data.Record#create}.
 * @constructor
 * @param {Object} config

 * @class Ext.data.JsonReader
 * @extends Ext.data.DataReader
 * Data reader class to create an Array of Ext.data.Record objects from a JSON response
 * based on mappings in a provided Ext.data.Record constructor.<br>
 * <p>
 * Example code:
 * <pre><code>
var Employee = Ext.data.Record.create([
    {name: 'name', mapping: 'name'},     // "mapping" property not needed if it's the same as "name"
    {name: 'occupation'}                 // This field will use "occupation" as the mapping.
]);
var myReader = new Ext.data.JsonReader({
    totalProperty: "results",    // The property which contains the total dataset size (optional)
    root: "rows",                // The property which contains an Array of row objects
    id: "id"                     // The property within each row object that provides an ID for the record (optional)
}, Employee);
</code></pre>
 * <p>
 * This would consume a JSON file like this:
 * <pre><code>
{ 'results': 2, 'rows': [
    { 'id': 1, 'name': 'Bill', occupation: 'Gardener' },
    { 'id': 2, 'name': 'Ben', occupation: 'Horticulturalist' } ]
}
</code></pre>
 * <p>It is possible to change a JsonReader's metadata at any time by including a
 * <b><tt>MetaData</tt></b> property in the data object. If this is detected in the
 * object, a {@link Ext.data.Store Store} object using this Reader will fire its
 * {@link Ext.data.Store#metachange metachange} event.</p>
 * <p>The <b><tt>MetaData</tt></b> property may contain any of the configuration
 * options for this class. Additionally, it may contain a <b><tt>fields</tt></b>
 * property which the JsonReader will use as an argument to {@link Ext.data.Record.create}
 * to configure the layout of the Records which it will produce.<p>
 * Using the <b><tt>MetaData</tt></b> property, and the Store's {@link Ext.data.Store#metachange metachange} event,
 * it is possible to have a Store-driven control initialize itself. The metachange
 * event handler may interrogate the <b><tt>MetaData</tt></b> property (which
 * may contain any user-defined properties needed) and the <b><tt>MetaData.fields</tt></b>
 * property to perform any configuration required.</p>
 * <p>To use this facility to send the same data as the above example without
 * having to code the creation of the Record constructor, you would create the
 * JsonReader like this:</p><pre><code>
var myReader = new Ext.data.JsonReader();
</code></pre>
 * <p>The first data packet from the server would configure the reader by
 * containing a metaData property as well as the data:</p><pre><code>
{
  'metaData': {
    totalProperty: 'results',
    root: 'rows',
    id: 'id',
    fields: [
      {name: 'name'},
      {name: 'occupation'} ]
   },
  'results': 2, 'rows': [
    { 'id': 1, 'name': 'Bill', occupation: 'Gardener' },
    { 'id': 2, 'name': 'Ben', occupation: 'Horticulturalist' } ]
}
</code></pre>

 * @cfg {String} root name of the property which contains the Array of row objects.
 * @cfg {String} id Name of the property within a row object that contains a record identifier value.

/**
 * @class Ext.Container
 * @extends Ext.BoxComponent
 * <p>Base class for any {@link Ext.BoxComponent} that can contain other components.  Containers handle the basic
 * behavior of containing items, namely adding, inserting and removing them.  The specific layout logic required
 * to visually render contained items is delegated to any one of the different {@link #layout} classes available.
 * This class is intended to be extended and should generally not need to be created directly via the new keyword.</p>
 * <p>When either specifying child {@link #items} of a Container, or dynamically adding components to a Container,
 * remember to consider how you wish the Container to arrange those child elements, and whether those child elements
 * need to be sized using one of Ext's built-in layout schemes.</p>
 * <p>By default, Containers use the {@link Ext.layout.ContainerLayout ContainerLayout} scheme. This simply renders
 * child components, appending them one after the other inside the Container, and does not apply any sizing at all.
 * This is a common source of confusion when widgets like GridPanels or TreePanels are added to Containers for
 * which no layout has been specified. If a Container is left to use the ContainerLayout scheme, none of its child
 * components will be resized, or changed in any way when the Container is resized.</p>
 * <p>A very common example of this is where a developer will attempt to add a GridPanel to a TabPanel by wrapping
 * the GridPanel <i>inside</i> a wrapping Panel and add that wrapping Panel to the TabPanel. This misses the point that
 * Ext's inheritance means that a GridPanel <b>is</b> a Component which can be added unadorned into a Container. If
 * that wrapping Panel has no layout configuration, then the GridPanel will not be sized as expected.<p>
 * <p>Below is an example of adding a newly created GridPanel to a TabPanel. This requires prior knowledge of how
 * to create GridPanels. See {@link Ext.grid.GridPanel}, {@link Ext.data.Store} and {@link Ext.data.JsonReader} as
 * well as the grid examples in the Ext installation's <tt>examples/grid</tt> directory.</p><pre><code>
//  Create the GridPanel.
myGrid = new Ext.grid.GridPanel({
    myStore,
    myColumnModel,
    title: 'Results',
});

myTabPanel.add(myGrid);
myTabPanel.setActiveItem(myGrid);

 * <p>The CardLayout's focal method is {@link #setActiveItem}.  Since only one panel is displayed at a time,

 * the next panel to display.  The layout itself does not provide a mechanism for handling this navigation,
 * so that functionality must be provided by the developer.</p>
 * <p>In the following example, a simplistic wizard setup is demonstrated.  A button bar is added
 * to the footer of the containing panel to provide navigation buttons.  The buttons will be handled by a
 * common navigation routine -- for this example, the implementation of that routine has been ommitted since
 * it can be any type of custom logic.  Note that other uses of a CardLayout (like a tab control) would require a
 * completely different implementation.  For serious implementations, a better approach would be to extend
 * CardLayout to provide the custom functionality needed.  Example usage:</p>
 * <pre><code>

    // It would call setActiveItem as needed, manage navigation button state, handle any
    // branching logic that might be required, handle alternate actions like cancellation
    // or finalization, etc.  A complete wizard implementation could get pretty
    // sophisticated depending on the complexity required, and should probably be
    // done as a subclass of CardLayout in a real-world implementation.

 * @class Ext.layout.AnchorLayout
 * @extends Ext.layout.ContainerLayout
 * <p>This is a layout that enables anchoring of contained elements relative to the container's dimensions.  If

 * This class is intended to be extended or created via the layout:'anchor' {@link Ext.Container#layout} config,
 * and should generally not need to be created directly via the new keyword.</p>
 * <p>AnchorLayout does not have any direct config options (other than inherited ones).  However, the container
 * using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>.  By default,
 * AnchorLayout will calculate anchor measurements based on the size of the container itself.  However, if
 * anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating anchor
 * measurements based on it instead, allowing the container to be sized independently of the anchoring logic if necessary.</p>
 * <p>The items added to an AnchorLayout can also supply an anchoring-specific config property of <b>anchor</b> which
 * is a string containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').
 * This value is what tells the layout how the item should be anchored to the container.  The following types of
 * anchor values are supported:
 * <ul>
 * <li><b>Percentage</b>: Any value between 1 and 100, expressed as a percentage.  The first anchor is the percentage
 * width that the item should take up within the container, and the second is the percentage height.  Example: '100% 50%'
 * would render an item the complete width of the container and 1/2 its height.  If only one anchor value is supplied
 * it is assumed to be the width value and the height will default to auto.</li>
 * <li><b>Offsets</b>: Any positive or negative integer value.  The first anchor is the offset from the right edge of
 * the container, and the second is the offset from the bottom edge.  Example: '-50 -100' would render an item the
 * complete width of the container minus 50 pixels and the complete height minus 100 pixels.  If only one anchor value
 * is supplied it is assumed to be the right offset value and the bottom offset will default to 0.</li>
 * <li><b>Sides</b>: Valid values are 'right' (or 'r') and 'bottom' (or 'b').  Either the container must have a fixed
 * size or an anchorSize config value defined at render time in order for these to have any effect.</li>
 * </ul>
 * <p>Anchor values can also be mixed as needed.  For example, '-50 75%' would render the width offset from the
 * container right edge by 50 pixels and 75% of the container's height.</p>

 * @class Ext.layout.ColumnLayout
 * @extends Ext.layout.ContainerLayout
 * <p>This is the layout style of choice for creating structural layouts in a multi-column format where the width of
 * each column can be specified as a percentage or fixed width, but the height is allowed to vary based on the content.
 * This class is intended to be extended or created via the layout:'column' {@link Ext.Container#layout} config,
 * and should generally not need to be created directly via the new keyword.</p>
 * <p>ColumnLayout does not have any direct config options (other than inherited ones), but it does support a
 * specific config property of <b><tt>columnWidth</tt></b> that can be included in the config of any panel added to it.  The
 * layout will use the columnWidth (if present) or width of each panel during layout to determine how to size each panel.
 * If width or columnWidth is not specified for a given panel, its width will default to the panel's width (or auto).</p>
 * <p>The width property is always evaluated as pixels, and must be a number greater than or equal to 1.
 * The columnWidth property is always evaluated as a percentage, and must be a decimal value greater than 0 and
 * less than 1 (e.g., .25).</p>
 * <p>The basic rules for specifying column widths are pretty simple.  The logic makes two passes through the
 * set of contained panels.  During the first layout pass, all panels that either have a fixed width or none
 * specified (auto) are skipped, but their widths are subtracted from the overall container width.  During the second
 * pass, all panels with columnWidths are assigned pixel widths in proportion to their percentages based on
 * the total <b>remaining</b> container width.  In other words, percentage width panels are designed to fill the space
 * left over by all the fixed-width and/or auto-width panels.  Because of this, while you can specify any number of columns
 * with different percentages, the columnWidths must always add up to 1 (or 100%) when added together, otherwise your
 * layout may not render as expected.  Example usage:</p>
 * <pre><code>
// All columns are percentages -- they must add up to 1
var p = new Ext.Panel({
    title: 'Column Layout - Percentage Only',
    layout:'column',

    },{
        title: 'Column 3',
        columnWidth: .15
    }]
});

// Mix of width and columnWidth -- all columnWidth values must add up
// to 1. The first column will take up exactly 120px, and the last two
// columns will fill the remaining container width.
var p = new Ext.Panel({
    title: 'Column Layout - Mixed',

 * @class Ext.layout.FormLayout
 * @extends Ext.layout.AnchorLayout
 * <p>This is a layout specifically designed for creating forms.
 * This class can be extended or created via the layout:'form' {@link Ext.Container#layout} config,
 * and should generally not need to be created directly via the new keyword.  However, when used in an application,
 * it will usually be preferrable to use a {@link Ext.form.FormPanel} (which automatically uses FormLayout as its layout
 * class) since it also provides built-in functionality for loading, validating and submitting the form.</p>
 * <p>Note that when creating a layout via config, the layout-specific config properties must be passed in via
 * the {@link Ext.Container#layoutConfig} object which will then be applied internally to the layout.  The container
 * using the FormLayout can also supply the following form-specific config properties which will be applied by the layout:
 * <ul>
 * <li><b>hideLabels</b>: (Boolean) True to hide field labels by default (defaults to false)</li>
 * <li><b>itemCls</b>: (String) A CSS class to add to the div wrapper that contains each field label
 * and field element (the default class is 'x-form-item' and itemCls will be added to that)</li>
 * <li><b>labelAlign</b>: (String) The default label alignment.  The default value is empty string ''
 * for left alignment, but specifying 'top' will align the labels above the fields.</li>
 * <li><b>labelPad</b>: (Number) The default padding in pixels for field labels (defaults to 5).  labelPad only
 * applies if labelWidth is also specified, otherwise it will be ignored.</li>
 * <li><b>labelWidth</b>: (Number) The default width in pixels of field labels (defaults to 100)</li>
 * </ul></p>
 * <p>Any type of components can be added to a FormLayout, but items that inherit from {@link Ext.form.Field}
 * can also supply the following field-specific config properties:
 * <ul>
 * <li><b>clearCls</b>: (String) The CSS class to apply to the special clearing div rendered directly after each
 * form field wrapper (defaults to 'x-form-clear-left')</li>
 * <li><b>fieldLabel</b>: (String) The text to display as the label for this field (defaults to '')</li>
 * <li><b>hideLabel</b>: (Boolean) True to hide the label and separator for this field (defaults to false).</li>
 * <li><b>itemCls</b>: (String) A CSS class to add to the div wrapper that contains this field label
 * and field element (the default class is 'x-form-item' and itemCls will be added to that).  If supplied,
 * itemCls at the field level will override the default itemCls supplied at the container level.</li>
 * <li><b>labelSeparator</b>: (String) The separator to display after the text of the label for this field
 * (defaults to a colon ':' or the layout's value for {@link #labelSeparator}).  To hide the separator use empty string ''.</li>
 * <li><b>labelStyle</b>: (String) A CSS style specification string to add to the field label for this field
 * (defaults to '' or the layout's value for {@link #labelStyle}).</li>

 * @extends Ext.layout.ContainerLayout
 * <p>This layout allows you to easily render content into an HTML table.  The total number of columns can be

 * This class is intended to be extended or created via the layout:'table' {@link Ext.Container#layout} config,
 * and should generally not need to be created directly via the new keyword.</p>
 * <p>Note that when creating a layout via config, the layout-specific config properties must be passed in via
 * the {@link Ext.Container#layoutConfig} object which will then be applied internally to the layout.  In the
 * case of TableLayout, the only valid layout config property is {@link #columns}.  However, the items added to a
 * TableLayout can supply the following table-specific config properties:</p>
 * <ul>
 * <li><b>rowspan</b> Applied to the table cell containing the item.</li>
 * <li><b>colspan</b> Applied to the table cell containing the item.</li>
 * <li><b>cellId</b> An id applied to the table cell containing the item.</li>
 * <li><b>cellCls</b> A CSS class name added to the table cell containing the item.</li>
 * </ul>
 * <p>The basic concept of building up a TableLayout is conceptually very similar to building up a standard
 * HTML table.  You simply add each panel (or "cell") that you want to include along with any span attributes
 * specified as the special config properties of rowspan and colspan which work exactly like their HTML counterparts.
 * Rather than explicitly creating and nesting rows and columns as you would in HTML, you simply specify the
 * total column count in the layoutConfig and start adding panels in their natural order from left to right,
 * top to bottom.  The layout will automatically figure out, based on the column count, rowspans and colspans,
 * how to position each panel within the table.  Just like with HTML tables, your rowspans and colspans must add
 * up correctly in your overall layout or you'll end up with missing and/or extra cells!  Example usage:</p>
 * <pre><code>
// This code will generate a layout table that is 3 columns by 2 rows
// with some spanning included.  The basic layout will be:
// +--------+-----------------+
// |   A    |   B             |
// |        |--------+--------|
// |        |   C    |   D    |

 * @class Ext.TabPanel
 * <p>A basic tab container. Tab panels can be used exactly like a standard {@link Ext.Panel} for layout
 * purposes, but also have special support for containing child Panels that get automatically converted into tabs.</p>
 * <p>There is no actual tab class &mdash; each tab is simply an {@link Ext.Panel}.  However, when rendered in a
 * TabPanel, each child Panel can fire additional events that only exist for tabs and are not available to other
 * Panels. These are:</p>
 * <ul>
 * <li><b>activate</b>: Fires when this Panel becomes the active tab.
 * <div class="mdetail-params">
 *      <strong style="font-weight: normal;">Listeners will be called with the following arguments:</strong>
 *      <ul><li><code>tab</code> : Panel<div class="sub-desc">The tab that was activated</div></li></ul>
 *  </div></li>
 * <li><b>deactivate</b>: Fires when this Panel that was the active tab becomes deactivated.
 * <div class="mdetail-params">
 *      <strong style="font-weight: normal;">Listeners will be called with the following arguments:</strong>
 *      <ul><li><code>tab</code> : Panel<div class="sub-desc">The tab that was deactivated</div></li></ul>
 *  </div></li>
 * </ul>
 * <p>There are several methods available for creating TabPanels. The output of the following examples should be
 * exactly the same. The tabs can be created and rendered completely in code, as in this example:</p>
 * <pre><code>
var tabs = new Ext.TabPanel({
    renderTo: Ext.getBody(),
    activeTab: 0,
    items: [{
        title: 'Tab 1',
        html: 'A simple tab'
    },{
        title: 'Tab 2',
        html: 'Another one'
    }]
});
</pre></code>
  * <p>TabPanels can also be rendered from markup in a couple of ways.  See the {@link #autoTabs} example for
  * rendering entirely from markup that is already structured correctly as a TabPanel (a container div with
  * one or more nested tab divs with class 'x-tab'). You can also render from markup that is not strictly
  * structured by simply specifying by id which elements should be the container and the tabs. Using this method,
  * tab content can be pulled from different elements within the page by id regardless of page structure.  Note
  * that the tab divs in this example contain the class 'x-hide-display' so that they can be rendered deferred
  * without displaying outside the tabs. You could alternately set {@link #deferredRender} to false to render all
  * content tabs on page load. For example:
  * <pre><code>
var tabs = new Ext.TabPanel({
    renderTo: 'my-tabs',
    activeTab: 0,
    items:[
        {contentEl:'tab1', title:'Tab 1'},
        {contentEl:'tab2', title:'Tab 2'}
    ]
});

// Note that the tabs do not have to be nested within the container (although they can be)
&lt;div id="my-tabs">&lt;/div>
&lt;div id="tab1" class="x-hide-display">A simple tab&lt;/div>
&lt;div id="tab2" class="x-hide-display">Another one&lt;/div>

	        {text: 'Item 1', handler: item1Handler},
	        {text: 'Item 2', handler: item2Handler},
        ]
   	})
});

// Instead of showing a menu, you provide any type of custom
// functionality you want when the dropdown arrow is clicked:
new Ext.SplitButton({
	renderTo: 'button-ct',
   	text: 'Options',
   	handler: optionsHandler,

         * the return button to enter input.

 * @class Ext.QuickTips
 * <p>Provides attractive and customizable tooltips for any element. The QuickTips
 * singleton is used to configure and manage tooltips globally for multiple elements
 * in a generic manner.  To create individual tooltips with maximum customizability,
 * you should consider either {@link Ext.Tip} or {@link Ext.ToolTip}.</p>
 * <p>Quicktips can be configured via tag attributes directly in markup, or by
 * registering quick tips programmatically via the {@link #register} method.</p>
 * <p>The singleton's instance of {@link Ext.QuickTip} is available via
 * {@link #getQuickTip}, and supports all the methods, and all the all the
 * configuration properties of Ext.QuickTip. These settings will apply to all
 * tooltips shown by the singleton.</p>
 * <p>Below is the summary of the configuration properties which can be used.
 * For detailed descriptions see {@link #getQuickTip}</p>
 * <p><b>QuickTips singleton configs (all are optional)</b></p>
 * <div class="mdetail-params"><ul><li>dismissDelay</li>
 * <li>hideDelay</li>
 * <li>maxWidth</li>
 * <li>minWidth</li>
 * <li>showDelay</li>
 * <li>trackMouse</li></ul></div>
 * <p><b>Target element configs (optional unless otherwise noted)</b></p>
 * <div class="mdetail-params"><ul><li>autoHide</li>
 * <li>cls</li>
 * <li>dismissDelay (overrides singleton value)</li>
 * <li>target (required)</li>
 * <li>text (required)</li>
 * <li>title</li>
 * <li>width</li></ul></div>
 * <p>Here is an example showing how some of these config options could be used:</p>
 * <pre><code>
// Init the singleton.  Any tag-based quick tips will start working.
Ext.QuickTips.init();

// Apply a set of config properties to the singleton
Ext.apply(Ext.QuickTips.getQuickTip(), {
    maxWidth: 200,
    minWidth: 100,
    showDelay: 50,
    trackMouse: true
});

// Manually register a quick tip for a specific element
q.register({
    target: 'my-div',
    title: 'My Tooltip',
    text: 'This tooltip was added in code',
    width: 100,
    dismissDelay: 20
});
</code></pre>
 * <p>To register a quick tip in markup, you simply add one or more of the valid QuickTip attributes prefixed with
 * the <b>ext:</b> namespace.  The HTML element itself is automatically set as the quick tip target. Here is the summary
 * of supported attributes (optional unless otherwise noted):</p>
 * <ul><li><b>hide</b>: Specifying "user" is equivalent to setting autoHide = false.  Any other value will be the
 * same as autoHide = true.</li>
 * <li><b>qclass</b>: A CSS class to be applied to the quick tip (equivalent to the 'cls' target element config).</li>
 * <li><b>qtip (required)</b>: The quick tip text (equivalent to the 'text' target element config).</li>
 * <li><b>qtitle</b>: The quick tip title (equivalent to the 'title' target element config).</li>
 * <li><b>qwidth</b>: The quick tip width (equivalent to the 'width' target element config).</li></ul>
 * <p>Here is an example of configuring an HTML element to display a tooltip from markup:</p>
 * <pre><code>
// Add a quick tip to an HTML button
&lt;input type="button" value="OK" ext:qtitle="OK Button" ext:qwidth="100"
     ext:qtip="This is a quick tip from markup!">&lt;/input>
</code></pre>

     * object containing any or all of the following properties can be passed:<ul>
     * <li><tt>text</tt> {String} : (optional) The status text to display.  If not specified, any current 
     * status text will remain unchanged.</li>
     * <li><tt>iconCls</tt> {String} : (optional) The CSS class used to customize the status icon (see 
     * {@link #iconCls} for details). If not specified, any current iconCls will remain unchanged.</li>
     * <li><tt>clear</tt> {Boolean/Number/Object} : (optional) Allows you to set an internal callback that will 
     * automatically clear the status text and iconCls after a specified amount of time has passed. If clear is not 
     * specified, the new status will not be auto-cleared and will stay until updated again or cleared using 
     * {@link #clearStatus}. If <tt>true</tt> is passed, the status will be cleared using {@link #autoClear}, 
     * {@link #defaultText} and {@link #defaultIconCls} via a fade out animation. If a numeric value is passed, 
     * it will be used as the callback interval (in milliseconds), overriding the {@link #autoClear} value. 
     * All other options will be defaulted as with the boolean option.  To customize any other options, 
     * you can pass an object in the format:<ul>
     *    <li><tt>wait</tt> {Number} : (optional) The number of milliseconds to wait before clearing 
     *    (defaults to {@link #autoClear}).</li>
     *    <li><tt>anim</tt> {Number} : (optional) False to clear the status immediately once the callback 
     *    executes (defaults to true which fades the status out).</li>
     *    <li><tt>useDefaults</tt> {Number} : (optional) False to completely clear the status text and iconCls
     *    (defaults to true which uses {@link #defaultText} and {@link #defaultIconCls}).</li>
