Before each invocation, Ext injects the property taskRunCount into the task object so * that calculations based on the repeat count can be performed.

The DomHelper class provides a layer of abstraction from DOM and transparently supports creating * elements via DOM or using HTML fragments. It also has the ability to create HTML fragment templates * from your DOM building code.

A specification object is used when creating elements. Attributes of this object * are assumed to be element attributes, except for 4 special attributes: *

This is an example, where an unordered list with 3 children items is appended to an existing * element with id 'my-div':

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:

The real power is in the built-in templating. Instead of creating or appending any elements, * {@link #createTemplate} returns a Template object which can be used over and over to * insert new elements. Revisiting the example above, we could utilize templating this time: *

Templates are applied using regular expressions. The performance is great, but if * you are adding a bunch of DOM elements using the same template, you can increase * performance even further by {@link Ext.Template#compile "compiling"} the template. * The way "{@link Ext.Template#compile compile()}" works is the template is parsed and * broken up at the different variable points and a dynamic function is created and eval'ed. * The generated function performs string concatenation of these parts and the passed * variables instead of using regular expressions. *

DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead * of DOM can significantly boost performance.

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. Usage:

Represents an HTML fragment template. Templates may be {@link #compile precompiled} * for greater performance.

DomQuery supports most of the CSS3 selectors spec, along with some custom selectors and basic XPath.

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.

Element Selectors:

Attribute Selectors:

The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.

Pseudo Classes:

CSS Value Selectors:

Object hash of "pseudo class" filter functions which are used when filtering selections. Each function is passed * two parameters:

A filter function returns an Array of DOM elements which conform to the pseudo class.

In addition to the provided pseudo classes listed above such as first-child and nth-child, * developers may add additional, custom psuedo class filters to select elements according to application-specific requirements.

For example, to filter <a> elements to only return links to external resources:

The DelayedTask class provides a convenient way to "buffer" the execution of a method, * performing setTimeout where a new timeout cancels the old timeout. When called, the * task will wait the specified time period before executing. If durng that time period, * the task is called again, the original call will be cancelled. This continues so that * the function is only called a single time for each iteration.

This method is especially useful for things like detecting whether a user has finished * typing in a text field. An example would be performing validation on a keypress. You can * use this class to buffer the keypress events for a certain number of milliseconds, and * perform only if they stop for that amount of time. Usage:

Note that we are using a DelayedTask here to illustrate a point. The configuration * option buffer for {@link Ext.util.Observable#addListener addListener/on} will * also setup a delayed task for you to buffer events.

A config object containing one or more event handlers to be added to this * object during initialization. This should be a valid listeners config object as specified in the * {@link #addListener} example for attaching multiple handlers at once.

While some ExtJs 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.DataView DataView}'s * {@link Ext.DataView#click click} event passing the node clicked on. To access DOM * events directly from a Component's HTMLElement, listeners must be added to the {@link Ext.Component#getEl Element} after the Component * has been rendered. A plugin can simplify this step:

An event may be set to bubble up an Observable parent hierarchy (See {@link Ext.Component#getBubbleTarget}) * by calling {@link #enableBubble}.

* Combining Options
* Using the options argument, it is possible to combine different types of listeners:
*
* A delayed, one-time listener. *

* Attaching multiple handlers in 1 call
* The method also allows for a single argument to be passed which is a config object containing properties * which specify multiple handlers. *

Enables events fired by this Observable to bubble up an owner hierarchy by calling * this.getBubbleTarget() if present. There is no implementation in the Observable base class.

This is commonly used by Ext.Components to bubble events to owner Containers. See {@link Ext.Component.getBubbleTarget}. The default * implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to * access the required target more quickly.

This makes any event fired on any instance of the passed class also fire a single event through * the class allowing for central handling of events on many instances at once.

Encapsulates a DOM element, adding simple DOM manipulation facilities, normalizing for browser differences.

All instances of this class inherit the methods of {@link Ext.Fx} making visual effects easily available to all DOM elements.

Note that the events documented in this class are not Ext events, they encapsulate browser events. To * access the underlying browser event, see {@link Ext.EventObject#browserEvent}. Some older * browsers may not support the full range of events. Which events are supported is beyond the control of ExtJs.

Many of the functions for manipulating an element have an optional "animate" parameter. This * parameter can be specified as boolean (true) for default animation effects.

To configure the effects, an object literal with animation options to use as the Element animation * configuration object can also be specified. Note that the supported Element animation configuration * options are a subset of the {@link Ext.Fx} animation options specific to Fx effects. The supported * Element animation configuration options are:

The Element animation object being used for the animation will be set on the options * object as "anim", which allows you to stop or manipulate the animation. Here is an example:

* Combining Options
* In the following examples, the shorthand form {@link #on} is used rather than the more verbose * addListener. The two are equivalent. Using the options argument, it is possible to combine different * types of listeners:
*
* A delayed, one-time listener that auto stops the event and adds a custom argument (forumId) to the * options object. The options object is available as the third parameter in the handler function.

* Code:


		el.on('click', this.onClick, this, {
		single: true,
		delay: 100,
		stopEvent : true,
		forumId: 4
		});

* Attaching multiple handlers in 1 call
* The method also allows for a single argument to be passed which is a config object containing properties * which specify multiple handlers.

* Code:


		el.on({
		'click' : {
		fn: this.onClick,
		scope: this,
		delay: 100
		},
		'mouseover' : {
		fn: this.onMouseOver,
		scope: this
		},
		'mouseout' : {
		fn: this.onMouseOut,
		scope: this
		}
		});

* Or a shorthand syntax:
* Code:


		el.on({
		'click' : this.onClick,
		'mouseover' : this.onMouseOver,
		'mouseout' : this.onMouseOut,
		scope: this
		});
		*

delegate

This is a configuration option that you can pass along when registering a handler for * an event to assist with event delegation. Event delegation is a technique that is used to * reduce memory consumption and prevent exposure to memory-leaks. By registering an event * for a container element as opposed to each element within a container. By setting this * configuration option to a simple selector, the target element will be filtered to look for * a descendant of the target. * For example:


		// using this markup:
		<div id='elId'>
		<p id='p1'>paragraph one</p>
		<p id='p2' class='clickable'>paragraph two</p>
		<p id='p3'>paragraph three</p>
		</div>
		// utilize event delegation to registering just one handler on the container element:
		el = Ext.get('elId');
		el.on(
		'click',
		function(e,t) {
		// handle click
		console.info(t.id); // 'p2'
		},
		this,
		{
		// filter the target element to be a descendant with the class 'clickable'
		delegate: '.clickable'
		}
		);

Blank: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").
One anchor (deprecated): 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. This method has been * deprecated in favor of the newer two anchor syntax below.
Two anchors: 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.

* 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. * Following are all of the supported anchor positions:

	Value  Description
	-----  -----------------------------
	tl     The top left corner (default)
	t      The center of the top edge
	tr     The top right corner
	l      The center of the left edge
	c      In the center of the element
	r      The center of the right edge
	bl     The bottom left corner
	b      The center of the bottom edge
	br     The bottom right corner

Example Usage:


	// align el to other-el using the default positioning ("tl-bl", non-constrained)
	el.alignTo("other-el");

	// align the top left corner of el with the top right corner of other-el (constrained to viewport)
	el.alignTo("other-el", "tr?");

	// align the bottom right corner of el with the center left edge of other-el
	el.alignTo("other-el", "br-l?");

	// align the center of el with the bottom left corner of other-el and
	// adjust the x position by -6 pixels (and the y position by 0)
	el.alignTo("other-el", "c-bl", [-6, 0]);

Animation Properties

The Animation Control Object enables gradual transitions for any member of an * element's style object that takes a numeric value including but not limited to * these properties:

bottom, top, left, right
height, width
margin, padding
borderWidth
opacity
fontSize
lineHeight

Animation Property Attributes

Each Animation Property is a config object with optional properties:

by* : relative change - start at current value, change by this value
from : ignore current value, start from this value
to* : start at current value, go to this value
unit : any allowable unit specification

* do not specify both to and by for an animation property

Animation Types

The supported animation types:

'run' : Default *


		var el = Ext.get('complexEl');
		el.animate(
		// animation control object
		{
		borderWidth: {to: 3, from: 0},
		opacity: {to: .3, from: 1},
		height: {to: 50, from: el.getHeight()},
		width: {to: 300, from: el.getWidth()},
		top  : {by: - 100, unit: 'px'},
		},
		0.35,      // animation duration
		null,      // callback
		'easeOut', // easing method
		'run'      // animation type ('run','color','motion','scroll')
		);
		*

'color' *

Animates transition of background, text, or border colors.


		el.animate(
		// animation control object
		{
		color: { to: '#06e' },
		backgroundColor: { to: '#e06' }
		},
		0.35,      // animation duration
		null,      // callback
		'easeOut', // easing method
		'color'    // animation type ('run','color','motion','scroll')
		);
		*

'motion' *

Animates the motion of an element to/from specific points using optional bezier * way points during transit.


		el.animate(
		// animation control object
		{
		borderWidth: {to: 3, from: 0},
		opacity: {to: .3, from: 1},
		height: {to: 50, from: el.getHeight()},

		[ 600, 800],
		[-100, 200]
		]
		}
		},

		'easeOut', // easing method
		'motion'   // animation type ('run','color','motion','scroll')
		);
		*

'scroll' *

Method Chaining

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. Also see {@link #callback}.

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:

	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

* Note: some Fx methods accept specific custom config parameters. The options shown in the Config Options * section below are common options that can be passed to any Fx method unless otherwise noted. * * @cfg {Function} callback A function called when the effect is finished. Note that effects are queued internally by the * Fx class, so a callback is not required to specify another effect -- effects can simply be chained together * and called in sequence (see note for Method Chaining above), for example:


	* el.slideIn().highlight();
	*

* The callback is intended for any additional code that should run once a particular effect has completed. The Element * being operated upon is passed as the first parameter. * * @cfg {Object} scope The scope (this reference) in which the {@link #callback} function is executed. Defaults to the browser window. * * @cfg {String} easing A valid Ext.lib.Easing value for the effect:

backBoth
backIn
backOut
bounceBoth
bounceIn
bounceOut
easeBoth
easeBothStrong
easeIn
easeInStrong
easeNone
easeOut
easeOutStrong
elasticBoth
elasticIn
elasticOut

* * @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 {Number} endOpacity Only applicable for {@link #fadeIn} or {@link #fadeOut}, a number between * 0 and 1 inclusive to configure the ending opacity value. * * @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 display CSS property instead of visibility 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 preceding effects should be stopped and removed before running current effect (only applies to non blocking effects) */ Ext.Fx = { // private - calls the function taking arguments from the argHash based on the key.

* {@link #extraParams}
* {@link #url}
* 
* 
// Default headers to pass in every request
Ext.Ajax.defaultHeaders = {

* 
* 
* Common Events you may want to set are:

* {@link Ext.data.Connection#beforerequest beforerequest}
* {@link Ext.data.Connection#requestcomplete requestcomplete}
* {@link Ext.data.Connection#requestexception requestexception}
* 
* 
// Example: show a spinner during all Ajax requests
Ext.Ajax.on('beforerequest', this.showSpinner, this);
Ext.Ajax.on('requestcomplete', this.hideSpinner, this);

* 
* 
* An example request:
* 
// Basic request

url: 'foo.php',
success: someFn,
failure: otherFn,
headers: {

* Usage:

* 
* var el = Ext.get("foo"); // Get Ext.Element object
* var mgr = el.getUpdater();
* mgr.update({
url: "http://myserver.com/index.php",
params: {

* var mgr = new Ext.Updater("myElementId");
* mgr.startAutoRefresh(60, "http://myserver.com/index.php");
* mgr.on("update", myFcnNeedsToKnow);
* 

* // short handed call directly from the element object
* Ext.get("foo").load({
url: "bar.php",
scripts: true,
params: "param1=foo&param2=bar",
text: "Loading Foo..."
* });
* 
* @constructor
* Create new Updater directly.
* @param {Mixed} el The element to update
* @param {Boolean} forceNew (optional) By default the constructor checks to see if the passed element already
* has an Updater and if it does it returns the same instance. This will skip that check (useful for extending this class).

/**
* @class Ext.XTemplate
* @extends Ext.Template
* A template class that supports advanced functionality like:

* Autofilling arrays using templates and sub-templates
* Conditional processing with basic comparison operators
* Basic math function support
* Execute arbitrary inline code with special built-in template variables
* Custom member functions
* 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
* 

* XTemplate provides the templating mechanism built into:

* {@link Ext.DataView}
* {@link Ext.ListView}
* {@link Ext.form.ComboBox}
* {@link Ext.grid.TemplateColumn}
* {@link Ext.grid.GroupingView}
* {@link Ext.menu.Item}
* {@link Ext.layout.MenuLayout}
* {@link Ext.ColorPalette}
* 

*
* For example usage {@link #XTemplate see the constructor}.
*
* @constructor
* The {@link Ext.Template#Template Ext.Template constructor} describes
* the acceptable parameters to pass to the constructor. The following
* examples demonstrate all of the supported features.
*
* 
*
* Sample Data
* 
* This is the data object used for reference in each code example:
* 
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
}]
};
* 
* 
* 
*
*
* Auto filling of arrays
* 
* The tpl tag and the for operator are used
* to process the provided data object:
* 

* If the value specified in for is an array, it will auto-fill,
* repeating the template block inside the tpl tag for each item in the
* array.
* If for="." is specified, the data object provided is examined.
* While processing an array, the special variable {#}
* will provide the current array index + 1 (starts at 1, not 0).
* 
* 
* 
<tpl for=".">...</tpl>       // loop through array at root node
<tpl for="foo">...</tpl>     // loop through array at foo node
<tpl for="foo.bar">...</tpl> // loop through array at foo.bar node
* 
* Using the sample data above:
* 
var tpl = new Ext.XTemplate(
'<p>Kids: ',
'<tpl for=".">',       // process the data.kids node
'<p>{#}. {name}</p>',  // use current array index to autonumber
'</tpl></p>'
);
tpl.overwrite(panel.body, data.kids); // pass the kids property of the data object
* 
* An example illustrating how the for property can be leveraged
* to access specified members of the provided data object to populate the template:
* 
var tpl = new Ext.XTemplate(
'<p>Name: {name}</p>',
'<p>Title: {title}</p>',
'<p>Company: {company}</p>',
'<p>Kids: ',
'<tpl for="kids">',     // interrogate the kids property within the data
'<p>{name}</p>',
'</tpl></p>'
);
tpl.overwrite(panel.body, data);  // pass the root node of the data object
* 
* Flat arrays that contain values (and not objects) can be auto-rendered
* using the special {.} variable inside a loop.  This variable
* will represent the value of the array at the current index:
* 
var tpl = new Ext.XTemplate(
'<p>{name}\'s favorite beverages:</p>',
'<tpl for="drinks">',
'<div> - {.}</div>',
'</tpl>'
);
tpl.overwrite(panel.body, data);
* 
* When processing a sub-template, for example while looping through a child array,
* you can access the parent object's members via the parent object:
* 
var tpl = new Ext.XTemplate(
'<p>Name: {name}</p>',
'<p>Kids: ',
'<tpl for="kids">',
'<tpl if="age > 1">',
'<p>{name}</p>',
'<p>Dad: {parent.name}</p>',
'</tpl>',
'</tpl></p>'
);
tpl.overwrite(panel.body, data);
* 
* 
* 
*
*
* Conditional processing with basic comparison operators
* 
* The tpl tag and the if operator are used
* to provide conditional checks for deciding whether or not to render specific
* parts of the template. Notes:

* Double quotes must be encoded if used within the conditional
* There is no else operator — if needed, two opposite
* if statements should be used.
* 
* 
<tpl if="age > 1 && age < 10">Child</tpl>
<tpl if="age >= 10 && age < 18">Teenager</tpl>
<tpl if="this.isGirl(name)">...</tpl>
<tpl if="id==\'download\'">...</tpl>
<tpl if="needsIcon"><img src="{icon}" class="{iconCls}"/></tpl>
// no good:
<tpl if="name == "Jack"">Hello</tpl>
// encode " if it is part of the condition, e.g.
<tpl if="name == &quot;Jack&quot;">Hello</tpl>
* 
* Using the sample data above:
* 
var tpl = new Ext.XTemplate(
'<p>Name: {name}</p>',
'<p>Kids: ',
'<tpl for="kids">',
'<tpl if="age > 1">',
'<p>{name}</p>',
'</tpl>',
'</tpl></p>'
);
tpl.overwrite(panel.body, data);
* 
* 
* 
*
*
* Basic math support
* 
* The following basic math operators may be applied directly on numeric
* data values:
* + - * /
* 
* For example:
* 
var tpl = new Ext.XTemplate(
'<p>Name: {name}</p>',
'<p>Kids: ',
'<tpl for="kids">',
'<tpl if="age &gt; 1">',  // <-- Note that the > is encoded
'<p>{#}: {name}</p>',  // <-- Auto-number each item
'<p>In 5 Years: {age+5}</p>',  // <-- Basic math
'<p>Dad: {parent.name}</p>',
'</tpl>',
'</tpl></p>'
);
tpl.overwrite(panel.body, data);

* 
* 
*
*
* Execute arbitrary inline code with special built-in template variables
* 
* Anything between {[ ... ]} is considered code to be executed
* in the scope of the template. There are some special variables available in that code:
* 

* values: The values in the current scope. If you are using
* scope changing sub-templates, you can change what values is.
* parent: The scope (values) of the ancestor template.
* xindex: If you are in a looping template, the index of the
* loop you are in (1-based).
* xcount: If you are in a looping template, the total length
* of the array you are looping.
* fm: An alias for Ext.util.Format.
* 
* This example demonstrates basic row striping using an inline code block and the
* xindex variable:
* 
var tpl = new Ext.XTemplate(
'<p>Name: {name}</p>',
'<p>Company: {[values.company.toUpperCase() + ", " + values.title]}</p>',
'<p>Kids: ',
'<tpl for="kids">',
'<div class="{[xindex % 2 === 0 ? "even" : "odd"]}">',
'{name}',
'</div>',
'</tpl></p>'
);
tpl.overwrite(panel.body, data);
* 
* 
* 
*
* Template member functions
* 
* One or more member functions can be specified in a configuration
* object passed into the XTemplate constructor for more complex processing:
* 
var tpl = new Ext.XTemplate(
'<p>Name: {name}</p>',
'<p>Kids: ',
'<tpl for="kids">',
'<tpl if="this.isGirl(name)">',
'<p>Girl: {name} - {age}</p>',
'</tpl>',
// use opposite if statement to simulate 'else' processing:
'<tpl if="this.isGirl(name) == false">',
'<p>Boy: {name} - {age}</p>',
'</tpl>',
'<tpl if="this.isBaby(age)">',
'<p>{name} is a baby!</p>',
'</tpl>',
'</tpl></p>',
{
// XTemplate configuration:
compiled: true,
disableFormats: true,
// member functions:
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

	/**
	* @cfg {Boolean} stateful
	* A flag which causes the Component to attempt to restore the state of
	* internal properties from a saved state on startup. The component must have
	* either a {@link #stateId} or {@link #id} assigned
	* for state to be managed. Auto-generated ids are not guaranteed to be stable
	* across page loads and cannot be relied upon to save and restore the same
	* state for a component.

	* 
For state saving to work, the state manager's provider must have been
	* set to an implementation of {@link Ext.state.Provider} which overrides the
	* {@link Ext.state.Provider#set set} and {@link Ext.state.Provider#get get}
	* methods to save and recall name/value pairs. A built-in implementation,
	* {@link Ext.state.CookieProvider} is available.
	* To set the state provider for the current page:
	* 
	Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
	expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now
	}));
	* 
	* A stateful Component attempts to save state when one of the events
	* listed in the {@link #stateEvents} configuration fires.
	* To save state, a stateful Component first serializes its state by
	* calling getState. By default, this function does
	* nothing. The developer must provide an implementation which returns an
	* object hash which represents the Component's restorable state.
	* The value yielded by getState is passed to {@link Ext.state.Manager#set}
	* which uses the configured {@link Ext.state.Provider} to save the object
	* keyed by the Component's {@link stateId}, or, if that is not
	* specified, its {@link #id}.
	* During construction, a stateful Component attempts to restore
	* its state by calling {@link Ext.state.Manager#get} passing the
	* {@link #stateId}, or, if that is not specified, the
	* {@link #id}.
	* The resulting object is passed to applyState.
	* The default implementation of applyState simply copies
	* properties into the object, but a developer may override this to support
	* more behaviour.
	* You can perform extra processing on state save and restore by attaching
	* handlers to the {@link #beforestaterestore}, {@link #staterestore},
	* {@link #beforestatesave} and {@link #statesave} events.

 * To use a pre-existing element as a BoxComponent, configure it so that you preset the el property to the
 * element to reference:

var pageHeader = new Ext.BoxComponent({
    el: 'my-header-div'
});
 * This may then be {@link Ext.Container#add added} to a {@link Ext.Container Container} as a child item.
 * To create a BoxComponent based around a HTML element to be created at render time, use the
 * {@link Ext.Component#autoEl autoEl} config option which takes the form of a
 * {@link Ext.DomHelper DomHelper} specification:

var myImage = new Ext.BoxComponent({

/**
* @class Ext.Container
* @extends Ext.BoxComponent
* Base class for any {@link Ext.BoxComponent} that may contain other Components. Containers handle the
* basic behavior of containing items, namely adding, inserting and removing items.
*
* The most commonly used Container classes are {@link Ext.Panel}, {@link Ext.Window} and {@link Ext.TabPanel}.
* If you do not need the capabilities offered by the aforementioned classes you can create a lightweight
* Container to be encapsulated by an HTML element to your specifications by using the
* {@link Ext.Component#autoEl autoEl} config option. This is a useful technique when creating
* embedded {@link Ext.layout.ColumnLayout column} layouts inside {@link Ext.form.FormPanel FormPanels}
* for example.
*
* The code below illustrates both how to explicitly create a Container, and how to implicitly
* create one using the 'container' xtype:

// explicitly create a Container
var embeddedColumns = new Ext.Container({
autoEl: 'div',  // This is the default
layout: 'column',
defaults: {
// implicitly create Container by specifying xtype
xtype: 'container',
autoEl: 'div', // This is the default.
layout: 'form',
columnWidth: 0.5,
style: {
padding: '10px'
}
},
//  The two items below will be Ext.Containers, each encapsulated by a <DIV> element.
items: [{
items: {
xtype: 'datefield',
name: 'startDate',
fieldLabel: 'Start date'
}
}, {
items: {
xtype: 'datefield',
name: 'endDate',
fieldLabel: 'End date'
}
}]
});

*
* Layout
* Container classes delegate the rendering of child Components to a layout
* manager class which must be configured into the Container using the
* {@link #layout} configuration property.
* When either specifying child {@link #items} of a Container,
* or dynamically {@link #add 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
* {@link #layout} schemes. By default, Containers use the
* {@link Ext.layout.ContainerLayout ContainerLayout} scheme which only
* renders child components, appending them one after the other inside the
* Container, and does not apply any sizing at all.
* A common mistake is when a developer neglects to specify a
* {@link #layout} (e.g. widgets like GridPanels or
* TreePanels are added to Containers for which no {@link #layout}
* has been specified). If a Container is left to use the default
* {@link Ext.layout.ContainerLayout ContainerLayout} scheme, none of its
* child components will be resized, or changed in any way when the Container
* is resized.
* Certain layout managers allow dynamic addition of child components.
* Those that do include {@link Ext.layout.CardLayout},
* {@link Ext.layout.AnchorLayout}, {@link Ext.layout.FormLayout}, and
* {@link Ext.layout.TableLayout}. For example:

//  Create the GridPanel.
var myNewGrid = new Ext.grid.GridPanel({
store: myStore,
columns: myColumnModel,
title: 'Results', // the title becomes the title of the tab
});

myTabPanel.add(myNewGrid); // {@link Ext.TabPanel} implicitly uses {@link Ext.layout.CardLayout CardLayout}
myTabPanel.{@link Ext.TabPanel#setActiveTab setActiveTab}(myNewGrid);
* 

* The example above adds a newly created GridPanel to a TabPanel. Note that
* a TabPanel uses {@link Ext.layout.CardLayout} as its layout manager which
* means all its child items are sized to {@link Ext.layout.FitLayout fit}
* exactly into its client area.
* 
Overnesting is a common problem.
* An example of overnesting occurs when a GridPanel is added to a TabPanel
* by wrapping the GridPanel inside a wrapping Panel (that has no
* {@link #layout} specified) and then add that wrapping Panel
* to the TabPanel. The point to realize is that a GridPanel is a
* Component which can be added directly to a Container. If the wrapping Panel
* has no {@link #layout} configuration, then the overnested
* GridPanel will not be sized as expected.

*
* 
Adding via remote configuration
*
* A server side script can be used to add Components which are generated dynamically on the server.
* An example of adding a GridPanel to a TabPanel where the GridPanel is generated by the server
* based on certain parameters:
* 

// execute an Ajax request to invoke server side script:
Ext.Ajax.request({
url: 'gen-invoice-grid.php',
// send additional parameters to instruct server script
params: {
startDate: Ext.getCmp('start-date').getValue(),
endDate: Ext.getCmp('end-date').getValue()
},
// process the response object to add it to the TabPanel:
success: function(xhr) {
var newComponent = eval(xhr.responseText); // see discussion below
myTabPanel.add(newComponent); // add the component to the TabPanel
myTabPanel.setActiveTab(newComponent);
},
failure: function() {
Ext.Msg.alert("Grid create failed", "Server communication failure");
}
});

* The server script needs to return an executable Javascript statement which, when processed
* using eval(), will return either a config object with an {@link Ext.Component#xtype xtype},
* or an instantiated Component. The server might return this for example:

(function() {
function formatDate(value){
return value ? value.dateFormat('M d, Y') : '';
};

var store = new Ext.data.Store({
url: 'get-invoice-data.php',
baseParams: {
startDate: '01/01/2008',
endDate: '01/31/2008'
},
reader: new Ext.data.JsonReader({
record: 'transaction',
idProperty: 'id',
totalRecords: 'total'
}, [
'customer',
'invNo',
{name: 'date', type: 'date', dateFormat: 'm/d/Y'},
{name: 'value', type: 'float'}
])
});

var grid = new Ext.grid.GridPanel({
title: 'Invoice Report',
bbar: new Ext.PagingToolbar(store),
store: store,
columns: [
{header: "Customer", width: 250, dataIndex: 'customer', sortable: true},
{header: "Invoice Number", width: 120, dataIndex: 'invNo', sortable: true},
{header: "Invoice Date", width: 100, dataIndex: 'date', renderer: formatDate, sortable: true},
{header: "Value", width: 120, dataIndex: 'value', renderer: 'usMoney', sortable: true}
],
});
store.load();
return grid;  // return instantiated component
})();

* When the above code fragment is passed through the eval function in the success handler
* of the Ajax request, the code is executed by the Javascript processor, and the anonymous function
* runs, and returns the instantiated grid component.
* Note: since the code above is generated by a server script, the baseParams for
* the Store, the metadata to allow generation of the Record layout, and the ColumnModel
* can all be generated into the code since these are all known on the server.

	/**
	* @cfg {String/Object} layout
	* *Important: In order for child items to be correctly sized and
	* positioned, typically a layout manager must be specified through
	* the layout configuration option.
	* 
The sizing and positioning of child {@link items} is the responsibility of
	* the Container's layout manager which creates and manages the type of layout
	* you have in mind.  For example:

	new Ext.Window({
	width:300, height: 300,
	layout: 'fit', // explicitly set layout manager: override the default (layout:'auto')
	items: [{
	title: 'Panel inside a Window'
	}]
	}).show();
	* 
	* If the {@link #layout} configuration is not explicitly specified for
	* a general purpose container (e.g. Container or Panel) the
	* {@link Ext.layout.ContainerLayout default layout manager} will be used
	* which does nothing but render child components sequentially into the
	* Container (no sizing or positioning will be performed in this situation).
	* Some container classes implicitly specify a default layout
	* (e.g. FormPanel specifies layout:'form'). Other specific
	* purpose classes internally specify/manage their internal layout (e.g.
	* GridPanel, TabPanel, TreePanel, Toolbar, Menu, etc.).
	* 
layout may be specified as either as an Object or
	* as a String:

	*
	* Specify as an Object

	*
	* type
	* 
The layout type to be used for this container.  If not specified,

	* If the defaults option is specified as a function, then the function will be called using this Container as the

	* For example, to automatically apply padding to the body of each of a set of

 * This class is intended to be extended or created via the layout:'card' {@link Ext.Container#layout} config,
 * and should generally not need to be created directly via the new keyword.
 * The CardLayout's focal method is {@link #setActiveItem}.  Since only one panel is displayed at a time,
 * the only way to move from one Component to the next is by calling setActiveItem, passing the id or index of
 * the next panel to display.  The layout itself does not provide a user interface for handling this navigation,
 * so that functionality must be provided by the developer.
 * 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:
 * 
var navHandler = function(direction){
    // This routine could contain business logic required to manage the navigation steps.
    // 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
* This is a layout that enables anchoring of contained elements relative to the container's dimensions.
* If the container is resized, all anchored items are automatically rerendered according to their
* {@link #anchor} rules.
* 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.
* AnchorLayout does not have any direct config options (other than inherited ones). By default,
* AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the
* container using the AnchorLayout can supply an anchoring-specific config property of anchorSize.
* 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.  For example:
* 
var viewport = new Ext.Viewport({
layout:'anchor',
anchorSize: {width:800, height:600},
items:[{
title:'Item 1',
html:'Content 1',
width:800,
anchor:'right 20%'
},{
title:'Item 2',
html:'Content 2',
width:300,
anchor:'50% 30%'
},{
title:'Item 3',
html:'Content 3',
width:600,
anchor:'-100 50%'
}]
});

	* @cfg {String} anchor
	* This configuation option is to be applied to child items of a container managed by
	* this layout (ie. configured with layout:'anchor').


	*
	* This value is what tells the layout how an item should be anchored to the container. items
	* added to an AnchorLayout accept an anchoring-specific config property of anchor which is a string
	* containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').
	* The following types of anchor values are supported:

	*
	* Percentage : 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.  For example:
	// two values specified
	anchor: '100% 50%' // render item complete width of the container and
	// 1/2 height of the container
	// one value specified
	anchor: '100%'     // the width value; the height will default to auto
	* 
	*
	* Offsets : Any positive or negative integer value.
	* This is a raw adjustment where the first anchor is the offset from the right edge of the container,
	* and the second is the offset from the bottom edge. For example:
	// two values specified
	anchor: '-50 -100' // render item the complete width of the container
	// minus 50 pixels and
	// the complete height minus 100 pixels.
	// one value specified
	anchor: '-50'      // anchor value is assumed to be the right offset value
	// bottom offset will default to 0
	* 
	*
	* Sides : 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.
	*
	* Mixed : 
	* Anchor values can also be mixed as needed.  For example, to render the width offset from the container
	* right edge by 50 pixels and 75% of the container's height use:
	* 
	anchor: '-50 75%'

/**
* @class Ext.layout.ColumnLayout
* @extends Ext.layout.ContainerLayout
* 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.
* ColumnLayout does not have any direct config options (other than inherited ones), but it does support a
* specific config property of columnWidth 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).
* 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).
* 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 remaining 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:
* 
// All columns are percentages -- they must add up to 1
var p = new Ext.Panel({
title: 'Column Layout - Percentage Only',
layout:'column',
items: [{
title: 'Column 1',
columnWidth: .25

},{
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',
layout:'column',
items: [{
title: 'Column 1',
width: 120
},{

* The regions of a BorderLayout are fixed at render time and thereafter, its child Components may not be removed or added.  To add/remove

 * @class Ext.layout.FormLayout
 * @extends Ext.layout.AnchorLayout
 * This layout manager is specifically designed for rendering and managing child Components of
 * {@link Ext.form.FormPanel forms}. It is responsible for rendering the labels of
 * {@link Ext.form.Field Field}s.
 *
 * This layout manager is used when a Container is configured with the layout:'form'
 * {@link Ext.Container#layout layout} config option, and should generally not need to be created directly
 * via the new keyword. See {@link Ext.Container#layout} for additional details.
 *
 * In an application, it will usually be preferrable to use a {@link Ext.form.FormPanel FormPanel}
 * (which is configured with FormLayout as its layout class by default) since it also provides built-in
 * functionality for {@link Ext.form.BasicForm#doAction loading, validating and submitting} the form.
 *
 * A {@link Ext.Container Container} using the FormLayout layout manager (e.g.
 * {@link Ext.form.FormPanel} or specifying layout:'form') can also accept the following
 * layout-specific config properties:

 * {@link Ext.form.FormPanel#hideLabels hideLabels}
 * {@link Ext.form.FormPanel#labelAlign labelAlign}
 * {@link Ext.form.FormPanel#labelPad labelPad}
 * {@link Ext.form.FormPanel#labelSeparator labelSeparator}
 * {@link Ext.form.FormPanel#labelWidth labelWidth}
 * 

 *
 * Any Component (including Fields) managed by FormLayout accepts the following as a config option:
 * 

 * {@link Ext.Component#anchor anchor}
 * 

 *
 * Any Component managed by FormLayout may be rendered as a form field (with an associated label) by
 * configuring it with a non-null {@link Ext.Component#fieldLabel fieldLabel}. Components configured
 * in this way may be configured with the following options which affect the way the FormLayout renders them:
 * 

 * {@link Ext.Component#clearCls clearCls}
 * {@link Ext.Component#fieldLabel fieldLabel}
 * {@link Ext.Component#hideLabel hideLabel}
 * {@link Ext.Component#itemCls itemCls}
 * {@link Ext.Component#labelSeparator labelSeparator}
 * {@link Ext.Component#labelStyle labelStyle}
 * 

 *
 * Example usage:
 * 
// Required if showing validation messages
Ext.QuickTips.init();

// you should usually use a FormPanel to also get its form functionality
// since it already creates a FormLayout internally.

 * @class Ext.layout.TableLayout
 * @extends Ext.layout.ContainerLayout
 * This layout allows you to easily render content into an HTML table.  The total number of columns can be
 * specified, and rowspan and colspan can be used to create complex layouts within the table.
 * 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.
 * 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:
 * 
 * rowspan Applied to the table cell containing the item.
 * colspan Applied to the table cell containing the item.
 * cellId An id applied to the table cell containing the item.
 * cellCls A CSS class name added to the table cell containing the item.
 * 
 * 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:
 * 
// This code will generate a layout table that is 3 columns by 2 rows

* @class Ext.Viewport

* the browser viewport and manages window resizing. There may only be one Viewport created

* added to the Viewport, either through its {@link #items}, or through the items, or the {@link #add}
* method of any of its child Panels may themselves have a layout.
* The Viewport does not provide scrolling, so child Panels within the Viewport should provide
* for scrolling if needed using the {@link #autoScroll} config.
* An example showing a classic application border layout:

new Ext.Viewport({
layout: 'border',

html: '<h1 class="x-panel-header">Page Title</h1>',
autoHeight: true,
border: false,

collapsible: true,
title: 'Navigation',
width: 200
// the west region might typically utilize a {@link Ext.tree.TreePanel TreePanel} or a Panel with {@link Ext.layout.AccordionLayout Accordion layout}
}, {
region: 'south',
title: 'Title for Panel',
collapsible: true,
html: 'Information goes here',

/**
* @class Ext.Panel
* @extends Ext.Container
* Panel is a container that has specific functionality and structural components that make
* it the perfect building block for application-oriented user interfaces.
* Panels are, by virtue of their inheritance from {@link Ext.Container}, capable
* of being configured with a {@link Ext.Container#layout layout}, and containing child Components.
* When either specifying child {@link Ext.Component#items items} of a Panel, or dynamically {@link Ext.Container#add adding} Components
* to a Panel, remember to consider how you wish the Panel to arrange those child elements, and whether
* those child elements need to be sized using one of Ext's built-in {@link Ext.Container#layout layout} schemes. By
* default, Panels 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.
* A Panel may also contain {@link #bbar bottom} and {@link #tbar top} toolbars, along with separate
* {@link #header}, {@link #footer} and {@link #body} sections (see {@link #frame} for additional
* information).
* Panel also provides built-in {@link #collapsible expandable and collapsible behavior}, along with
* a variety of {@link #tools prebuilt tool buttons} that can be wired up to provide other customized
* behavior.  Panels can be easily dropped into any {@link Ext.Container Container} or layout, and the
* layout and rendering pipeline is {@link Ext.Container#add completely managed by the framework}.

/**
* @class Ext.ProgressBar

* An updateable progress bar component.  The progress bar supports two different modes: manual and automatic.
* In manual mode, you are responsible for showing, updating (via {@link #updateProgress}) and clearing the
* progress bar as needed from your own code.  This method is most appropriate when you want to show progress
* throughout an operation that has predictable points of interest at which you can update the control.
* In automatic mode, you simply call {@link #wait} and let the progress bar run indefinitely, only clearing it
* once the operation is complete.  You can optionally have the progress bar wait for a specific amount of time
* and then clear itself.  Automatic mode is most appropriate for timed operations or asynchronous operations in
* which you have no need for indicating intermediate progress.
* @cfg {Float} value A floating point value between 0 and 1 (e.g., .5, defaults to 0)
* @cfg {String} text The progress bar text (defaults to '')
* @cfg {Mixed} textEl The element to render the progress text to (defaults to the progress

	will run indefinitely until reset is called)
	interval   Number        The length of time in milliseconds between each progress update
	(defaults to 1000 ms)
	animate    Boolean       Whether to animate the transition of the progress bar. If this value is

	increment  Number        The number of progress update segments to display within the progress
	bar (defaults to 10).  If the bar reaches the end and is still
	updating, it will automatically wrap back to the beginning.
	text       String        Optional text to display in the progress bar element (defaults to '').
	fn         Function      A callback function to execute after the progress bar finishes auto-
	updating.  The function will be called with no arguments.  This function
	will be ignored if duration is not specified since in that case the
	progress bar can only be stopped programmatically, so any required function
	should be called by the same code after it resets the progress bar.
	scope      Object        The scope that is passed to the callback function (only applies when
	duration and fn are both passed).

	* Defines the interface and base operation of items that that can be
	* dragged or can be drop targets.  It was designed to be extended, overriding
	* the event handlers for startDrag, onDrag, onDragOver and onDragOut.
	* Up to three html elements can be associated with a DragDrop instance:
	* 
	* linked element: the element that is passed into the constructor.
	* This is the element which defines the boundaries for interaction with
	* other DragDrop objects.
	* 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.
	* 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}.
	* 
	* 
	* This class should not be instantiated until the onload event to ensure that
	* the associated elements are available.
	* The following would define a DragDrop obj that would interact with any
	* other DragDrop obj in the "group1" group:
	* 	*  dd = new Ext.dd.DragDrop("div1", "group1");
	* 
	* Since none of the event handlers have been implemented, nothing would
	* 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...

 * Constructors for this class are generated by passing an Array of field definition objects to {@link #create}.
 * Instances are usually only created by {@link Ext.data.Reader} implementations when processing unformatted data
 * objects.
 * Note that an instance of a Record class may only belong to one {@link Ext.data.Store Store} at a time.
 * In order to copy data from one Store to another, use the {@link #copy} method to create an exact
 * copy of the Record, and insert the new instance into the other Store.
 * When serializing a Record for submission to the server, be aware that it contains many private
 * properties, and also a reference to its owning Store which in turn holds references to its Records.
 * This means that a whole Record may not be encoded using {@link Ext.util.JSON.encode}. Instead, use the
 * {@link #data} and {@link #id} properties.
 * Record objects generated by this constructor inherit all the methods of Ext.data.Record listed below.
 * @constructor
 * This constructor should not be used to create Record objects. Instead, use {@link #create} to
 * generate a subclass of Ext.data.Record configured with information about its constituent fields.

 * 
The generated constructor has the same signature as this constructor.
 * @param {Object} data (Optional) An object, the properties of which provide values for the new Record's
 * fields. If not specified the {@link Ext.data.Field#defaultValue defaultValue}
 * for each field will be assigned.

 * @class Ext.data.Store

 * The Store class encapsulates a client side cache of {@link Ext.data.Record Record}
 * objects which provide input data for Components such as the {@link Ext.grid.GridPanel GridPanel},
 * the {@link Ext.form.ComboBox ComboBox}, or the {@link Ext.DataView DataView}.
 * Retrieving Data
 * A Store object may access a data object using:

 * {@link #proxy configured implementation} of {@link Ext.data.DataProxy DataProxy}
 * {@link #data} to automatically pass in data
 * {@link #loadData} to manually pass in data
 * 

 * Reading Data
 * A Store object has no inherent knowledge of the format of the data object (it could be
 * an Array, XML, or JSON). A Store object uses an appropriate {@link #reader configured implementation}
 * of a {@link Ext.data.DataReader DataReader} to create {@link Ext.data.Record Record} instances from the data
 * object.
 * Store Types
 * There are several implementations of Store available which are customized for use with
 * a specific DataReader implementation.  Here is an example using an ArrayStore which implicitly
 * creates a reader commensurate to an Array data object.
 * 
var myStore = new Ext.data.ArrayStore({
    fields: ['fullname', 'first'],
    idIndex: 0 // id for each record will be the first element
});
 * 
 * For custom implementations create a basic {@link Ext.data.Store} configured as needed:
 * 
// create a {@link Ext.data.Record Record} constructor:
var rt = Ext.data.Record.create([
    {name: 'fullname'},
    {name: 'first'}
]);
var myStore = new Ext.data.Store({
    // explicitly create reader
    reader: new Ext.data.ArrayReader(
        {
            idIndex: 0  // id for each record will be the first element
        },
        rt // recordType
    )
});
 * 
 * Load some data into store (note the data object is an array which corresponds to the reader):
 * 
var myData = [
    [1, 'Fred Flintstone', 'Fred'],  // note that id for the record is the first element
    [2, 'Barney Rubble', 'Barney']
];
myStore.loadData(myData);
 * 
 * Records are cached and made available through accessor functions.  An example of adding
 * a record to the store:
 * 
var defaultData = {
    fullname: 'Full Name',
    first: 'First Name'
};
var recId = 100; // provide unique id for the record
var r = new myStore.recordType(defaultData, ++recId); // create new record
myStore.{@link #insert}(0, r); // insert a new record into the store (also see {@link #add})
 * 
 * Writing Data
 * And new in Ext version 3, use the new {@link Ext.data.DataWriter DataWriter} to create an automated, Writable Store
 * along with RESTful features.
 * @constructor
 * Creates a new Store.
 * @param {Object} config A config object containing the objects needed for the Store to access data,
 * and read the data into Records.

/**
* @class Ext.data.DataWriter
* Ext.data.DataWriter facilitates create, update, and destroy actions between
* an Ext.data.Store and a server-side framework. A Writer enabled Store will
* automatically manage the Ajax requests to perform CRUD actions on a Store.
* Ext.data.DataWriter is an abstract base class which is intended to be extended
* and should not be created directly. For existing implementations, see
* {@link Ext.data.JsonWriter}.
* Creating a writer is simple:
* 
var writer = new Ext.data.JsonWriter({
encode: false   // <--- false causes data to be printed to jsonData config-property of Ext.Ajax#reqeust
});
* 
* * Same old JsonReader as Ext-2.x:
* 
var reader = new Ext.data.JsonReader({idProperty: 'id'}, [{name: 'first'}, {name: 'last'}, {name: 'email'}]);
* 
*
* The proxy for a writer enabled store can be configured with a simple url:
* 
// Create a standard HttpProxy instance.
var proxy = new Ext.data.HttpProxy({
url: 'app.php/users'    // <--- Supports "provides"-type urls, such as '/users.json', '/products.xml' (Hello Rails/Merb)
});
* 
* For finer grained control, the proxy may also be configured with an API:
* 
// Maximum flexibility with the API-configuration
var proxy = new Ext.data.HttpProxy({
api: {
read    : 'app.php/users/read',
create  : 'app.php/users/create',
update  : 'app.php/users/update',
destroy : {  // <--- Supports object-syntax as well
url: 'app.php/users/destroy',
method: "DELETE"
}
}
});
* 
* Pulling it all together into a Writer-enabled Store:
* 
var store = new Ext.data.Store({
proxy: proxy,
reader: reader,
writer: writer,
autoLoad: true,
autoSave: true  // -- Cell-level updates.
});
* 
* Initiating write-actions automatically, using the existing Ext2.0 Store/Record API:
* 
var rec = store.getAt(0);
rec.set('email', 'foo@bar.com');  // <--- Immediately initiates an UPDATE action through configured proxy.

store.remove(rec);  // <---- Immediately initiates a DESTROY action through configured proxy.
* 
* For record/batch updates, use the Store-configuration {@link Ext.data.Store#autoSave autoSave:false}
* 
var store = new Ext.data.Store({
proxy: proxy,
reader: reader,
writer: writer,
autoLoad: true,
autoSave: false  // -- disable cell-updates
});

var urec = store.getAt(0);
urec.set('email', 'foo@bar.com');

var drec = store.getAt(1);
store.remove(drec);

// Push the button!
store.save();
* 
* @constructor Create a new DataWriter
* @param {Object} meta Metadata configuration options (implementation-specific)
* @param {Object} recordType Either an Array of field definition objects as specified
* in {@link Ext.data.Record#create}, or an {@link Ext.data.Record} object created

 * The parameter to a DataProxy constructor may be an {@link Ext.data.Connection} or can also be the
 * config object to an {@link Ext.data.Connection}.
 * Custom implementations must implement either the doRequest method (preferred) or the
 * load method (deprecated). See
 * {@link Ext.data.HttpProxy}.{@link Ext.data.HttpProxy#doRequest doRequest} or
 * {@link Ext.data.HttpProxy}.{@link Ext.data.HttpProxy#load load} for additional details.
 * Example 1
 * 
proxy: new Ext.data.ScriptTagProxy({

 * 
 * Example 2

* @class Ext.data.ScriptTagProxy

* 
* Note that if you are retrieving data from a page that is in a domain that is NOT the same as the originating domain
* of the running page, you must use this class, rather than HttpProxy.

* 

* The content passed back from a server resource requested by a ScriptTagProxy must be executable JavaScript
* source code because it is used as the source inside a <script> tag.

* 

* In order for the browser to process the returned data, the server must wrap the data object
* with a call to a callback function, the name of which is passed as a parameter by the ScriptTagProxy.
* Below is a Java example for a servlet which returns data for either a ScriptTagProxy, or an HttpProxy
* depending on whether the callback name was passed:
* 

* 

boolean scriptTag = false;
String cb = request.getParameter("callback");

out.write(cb + "(");
}
out.print(dataBlock.toJsonString());
if (scriptTag) {
out.write(");");

* Below is a PHP example to do the same thing:

$callback = $_REQUEST['callback'];

// Create the output object.
$output = array('a' => 'Apple', 'b' => 'Banana');

//start output
if ($callback) {
header('Content-Type: text/javascript');
echo $callback . '(' . json_encode($output) . ');';
} else {
header('Content-Type: application/x-json');
echo json_encode($output);
}

* Below is the ASP.Net code to do the same thing:

String jsonString = "{success: true}";
String cb = Request.Params.Get("callback");
String responseString = "";
if (!String.IsNullOrEmpty(cb)) {
responseString = cb + "(" + jsonString + ")";
} else {
responseString = jsonString;

 * @class Ext.data.Types
 * This is s static class containing the system-supplied data types which may be given to a {@link Ext.data.Field Field}.

 * 
The properties in this class are used as type indicators in the {@link Ext.data.Field Field} class, so to
 * test whether a Field is of a certain type, compare the {@link Ext.data.Field#type type} property against properties
 * of this class.
 * Developers may add their own application-specific data types to this class. Definition names must be UPPERCASE.
 * each type definition must contain three properties:
 * 
 * convert : FunctionA 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:
 * 
 * v : MixedThe data value as read by the Reader, if undefined will use
 * the configured {@link Ext.data.Field#defaultValue defaultValue}.
 * rec : MixedThe data object containing the row as read by the Reader.
 * Depending on the Reader type, this could be an Array ({@link Ext.data.ArrayReader ArrayReader}), an object
 * ({@link Ext.data.JsonReader JsonReader}), or an XML element ({@link Ext.data.XMLReader XMLReader}).
 * 
 * sortType : Function A function to convert the stored data into comparable form, as defined by {@link Ext.data.SortTypes}.
 * type : String A textual data type name.
 * 
 * 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 lat and long, you would define a new data type like this:
 *
// Add a new Field data type which stores a VELatLong object in the Record.
Ext.data.Types.VELATLONG = {
    convert: function(v, data) {
        return new VELatLong(data.lat, data.long);
    },
    sortType: function(v) {
        return v.Latitude;  // When sorting, order by latitude
    },
    type: 'VELatLong'
};

 * Then, when declaring a Record, use 

var types = Ext.data.Types; // allow shorthand type access
UnitRecord = Ext.data.Record.create([
    { name: 'unitName', mapping: 'UnitName' },
    { name: 'curSpeed', mapping: 'CurSpeed', type: types.INT },

 * Example code:
 * 
var myReader = new Ext.data.JsonReader({
    // metadata configuration options:
    {@link #idProperty}: 'id'
    {@link #root}: 'rows',
    {@link #totalProperty}: 'results',

    // the fields config option will internally create an {@link Ext.data.Record}
    // constructor that provides mapping for reading the record data objects
    {@link Ext.data.DataReader#fields fields}: [
        // map Record's 'firstname' field to data object's key of same name
        {name: 'name'},
        // map Record's 'job' field to data object's 'occupation' key
        {name: 'job', mapping: 'occupation'}
    ]
});

 * This would consume a JSON data object of the form:

{
    results: 2000, // Reader's configured {@link #totalProperty}
    rows: [        // Reader's configured {@link #root}
        // record data objects:
        { {@link #idProperty id}: 1, firstname: 'Bill', occupation: 'Gardener' },
        { {@link #idProperty id}: 2, firstname: 'Ben' , occupation: 'Horticulturalist' },
        ...
    ]
}

 * Automatic configuration using metaData
 * It is possible to change a JsonReader's metadata at any time by including
 * a metaData property in the JSON data object. If the JSON data
 * object has a metaData property, a {@link Ext.data.Store Store}
 * object using this Reader will reconfigure itself to use the newly provided
 * field definition and fire its {@link Ext.data.Store#metachange metachange}
 * event. The metachange event handler may interrogate the metaData
 * property to perform any configuration required.
 * Note that reconfiguring a Store potentially invalidates objects which may
 * refer to Fields or Records which no longer exist.
 * To use this facility you would create the JsonReader like this:

var myReader = new Ext.data.JsonReader();

 * The first data packet from the server would configure the reader by
 * containing a metaData property and the data. For
 * example, the JSON data object might take the form:

{
    metaData: {
        "{@link #idProperty}": "id",
        "{@link #root}": "rows",
        "{@link #totalProperty}": "results"
        "{@link #successProperty}": "success",
        "{@link Ext.data.DataReader#fields fields}": [
            {"name": "name"},
            {"name": "job", "mapping": "occupation"}
        ],
        // used by store to set its sortInfo
        "sortInfo":{
           "field": "name",
           "direction": "ASC"
        },
        // {@link Ext.PagingToolbar paging data} (if applicable)
        "start": 0,
        "limit": 2,
        // custom property
        "foo": "bar"
    },
    // Reader's configured {@link #successProperty}
    "success": true,
    // Reader's configured {@link #totalProperty}
    "results": 2000,
    // Reader's configured {@link #root}
    // (this data simulates 2 results {@link Ext.PagingToolbar per page})
    "rows": [ // *Note: this must be an Array
        { "id": 1, "name": "Bill", "occupation": "Gardener" },

}
 *

/**
* @class Ext.Direct
* @extends Ext.util.Observable
* Overview
*
* Ext.Direct aims to streamline communication between the client and server
* by providing a single interface that reduces the amount of common code
* typically required to validate data and handle returned data packets
* (reading data, error conditions, etc).
*
* The Ext.direct namespace includes several classes for a closer integration
* with the server-side. The Ext.data namespace also includes classes for working
* with Ext.data.Stores which are backed by data from an Ext.Direct method.
*
* Specification
*
* For additional information consult the
* Ext.Direct Specification.
*
* Providers
*
* Ext.Direct uses a provider architecture, where one or more providers are
* used to transport data to and from the server. There are several providers
* that exist in the core at the moment:

*
* {@link Ext.direct.JsonProvider JsonProvider} for simple JSON operations
* {@link Ext.direct.PollingProvider PollingProvider} for repeated requests
* {@link Ext.direct.RemotingProvider RemotingProvider} exposes server side
* on the client.
* 
*
* A provider does not need to be invoked directly, providers are added via
* {@link Ext.Direct}.{@link Ext.Direct#add add}.
*
* Router
*
* Ext.Direct utilizes a "router" on the server to direct requests from the client
* to the appropriate server-side method. Because the Ext.Direct API is completely
* platform-agnostic, you could completely swap out a Java based server solution
* and replace it with one that uses C# without changing the client side JavaScript
* at all.
*
* Server side events
*
* Custom events from the server may be handled by the client by adding
* listeners, for example:
* 
{"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}

// add a handler for a 'message' event sent by the server
Ext.Direct.on('message', function(e){
out.append(String.format('<p><i>{0}</i></p>', e.data));
out.el.scrollTo('t', 100000, true);
});
* 
* @singleton

 * Applies drag handles to an element to make it resizable. The drag handles are inserted into the element
 * and positioned absolute. Some elements, such as a textarea or image, don't support this. To overcome that, you can wrap
 * the textarea in a div and set 'resizeChild' to true (or to the id of the element), or set wrap:true in your config and
 * the element will be wrapped for you automatically.
 * Here is the list of valid resize handles:

------  -------------------
 'n'     north
 's'     south
 'e'     east
 'w'     west
 'nw'    northwest
 'sw'    southwest
 'se'    southeast
 'ne'    northeast
 'all'   all

    minHeight: 100,
    maxWidth: 500,
    maxHeight: 400,
    pinned: true
});

 * To hide a particular handle, set its display to none in CSS, or through script:

 * resizer.east.setDisplayed(false);
 * @constructor
 * Create a new resizable component
 * @param {Mixed} el The id or element to resize
 * @param {Object} config configuration options

/**
* @class Ext.Window
* @extends Ext.Panel
* A specialized panel intended for use as an application window.  Windows are floated, {@link #resizable}, and
* {@link #draggable} by default.  Windows can be {@link #maximizable maximized} to fill the viewport,
* restored to their prior size, and can be {@link #minimize}d.
* Windows can also be linked to a {@link Ext.WindowGroup} or managed by the {@link Ext.WindowMgr} to provide
* grouping, activation, to front, to back and other application-specific behavior.
* By default, Windows will be rendered to document.body. To {@link #constrain} a Window to another element
* specify {@link Ext.Component#renderTo renderTo}.
* Note: By default, the {@link #closable close} header tool destroys the Window resulting in
* destruction of any child Components. This makes the Window object, and all its descendants unusable. To enable
* re-use of a Window, use {@link #closeAction closeAction: 'hide'}.

		* cancel:'Bar'}), or false to not show any buttons (defaults to false)
		* closable : BooleanFalse to hide the top-right close button (defaults to true). Note that

		* defaultTextHeight : NumberThe default height in pixels of the message box's multiline textarea
		* if displayed (defaults to 75)
		* fn : FunctionA callback function which is called when the dialog is dismissed either
		* by clicking on the configured buttons, or on the dialog close button, or by pressing
		* the return button to enter input.
		* Progress and wait dialogs will ignore this option since they do not respond to user
		* actions and can only be closed programmatically, so any required function should be called
		* by the same code after it closes the dialog. Parameters passed:

		* buttonId : StringThe ID of the button pressed, one of:
		* ok
		* yes
		* no
		* cancel
		* 
		* text : StringValue of the input field if either prompt

		* 

		* scope : ObjectThe scope of the callback function
		* icon : StringA CSS class that provides a background image to be used as the body icon for the
		* dialog (e.g. Ext.MessageBox.WARNING or 'custom-class') (defaults to '')
		* iconCls : StringThe standard {@link Ext.Window#iconCls} to
		* add an optional header icon (defaults to '')
		* maxWidth : NumberThe maximum width in pixels of the message box (defaults to 600)
		* minWidth : NumberThe minimum width in pixels of the message box (defaults to 100)
		* modal : BooleanFalse to allow user interaction with the page while the message box is
		* displayed (defaults to true)
		* msg : StringA string that will replace the existing message box body text (defaults to the
		* XHTML-compliant non-breaking space character '&#160;')
		* multiline : Boolean
		* True to prompt the user to enter multi-line text (defaults to false)
		* progress : BooleanTrue to display a progress bar (defaults to false)
		* progressText : StringThe text to display inside the progress bar if progress = true (defaults to '')
		* prompt : BooleanTrue to prompt the user to enter single-line text (defaults to false)
		* proxyDrag : BooleanTrue to display a lightweight proxy while dragging (defaults to false)
		* title : StringThe title text
		* value : StringThe string value to set into the active textbox element if displayed
		* wait : BooleanTrue to display a progress bar (defaults to false)
		* waitConfig : ObjectA {@link Ext.ProgressBar#waitConfig} object (applies only if wait = true)
		* width : NumberThe width of the dialog in pixels
		* 
		* Example usage:
		* 
		Ext.Msg.show({
		title: 'Address',
		msg: 'Please enter your address:',
		width: 300,
		buttons: Ext.MessageBox.OKCANCEL,
		multiline: true,
