* {@link Ext.Component#id id} (see {@link #get}, or the convenience method {@link Ext#getCmp Ext.getCmp}).
*
This object also provides a registry of available Component classes
* indexed by a mnemonic code known as the Component's {@link Ext.Component#xtype xtype}.
* The {@link Ext.Component#xtype xtype} provides a way to avoid instantiating child Components
* when creating a full, nested config object for a complete Ext page.
*
A child Component may be specified simply as a config object
* as long as the correct {@link Ext.Component#xtype xtype} is specified so that if and when the Component
* needs rendering, the correct type can be looked up for lazy instantiation.

* Components may be added to a Container through the {@link Ext.Container#items items} config option at the time the Container is created,
* or they may be added dynamically via the {@link Ext.Container#add add} method.
*
The Component base class has built-in support for basic hide/show and enable/disable behavior.
*
All Components are registered with the {@link Ext.ComponentMgr} on construction so that they can be referenced at any time via
* {@link Ext#getCmp}, passing the {@link #id}.
*
All user-developed visual widgets that are required to participate in automated lifecycle and size management should subclass Component (or
* {@link Ext.BoxComponent} if managed box model handling is required, ie height and width management).
*
See the Creating new UI controls tutorial for details on how
* and to either extend or augment ExtJs base classes to create custom Components.
*
Every component has a specific xtype, which is its Ext-specific type name, along with methods for checking the
* xtype like {@link #getXType} and {@link #isXType}. This is the list of all valid xtypes:
* @constructor
* @param {Ext.Element/String/Object} config The configuration options may be specified as either:

/**
* @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.
*/
/**
* @cfg {String} stateId
* The unique id for this component to use for state management purposes

See {@link #stateful} for an explanation of saving and
* restoring Component state.

/**
*
Render this Component into the passed HTML element.

If you are using a {@link Ext.Container Container} object to house this Component, then
* do not use the render method.
*
A Container's child Components are rendered by that Container's
* {@link Ext.Container#layout layout} manager when the Container is first rendered.
*
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}, {@link Ext.layout.TableLayout}.
*
If the Container is already rendered when a new child Component is added, you may need to call
* the Container's {@link Ext.Container#doLayout doLayout} to refresh the view which causes any
* unrendered child Components to be rendered. This is required so that you can add multiple
* child components if needed while only refreshing the layout once.
*
When creating complex UIs, it is important to remember that sizing and positioning
* of child items is the responsibility of the Container's {@link Ext.Container#layout layout} manager.
* If you expect child items to be sized in response to user interactions, you must
* configure the Container with a layout manager which creates and manages the type of layout you
* have in mind.
*
Omitting the Container's {@link Ext.Container#layout layout} config means that a basic
* layout manager is used which does nothing but render child components sequentially into the
* Container. No sizing or positioning will be performed in this situation.
* @param {Element/HTMLElement/String} container (optional) The element this Component should be
* rendered into. If it is being created from existing markup, this should be omitted.
* @param {String/Number} position (optional) The element ID or DOM node index within the container before

An Action is a piece of reusable functionality that can be abstracted out of any particular component so that it

* updates across any components that support the Action interface (primarily {@link Ext.Toolbar}, {@link Ext.Button}
* and {@link Ext.menu.Menu} components).
*
Aside from supporting the config object interface, any component that needs to use Actions must also support
* the following method list, as these will be called as needed by the Action class: setText(string), setIconCls(string),
* setDisabled(boolean), setVisible(boolean) and setHandler(function).
* Example usage:
*
// Define the shared action. Each component below will have the same
// display text and icon, and will display the same message on click.
var action = new Ext.Action({
{@link #text}: 'Do something',
{@link #handler}: function(){

* @class Ext.BoxComponent
* @extends Ext.Component
*
Base class for any {@link Ext.Component Component} that is to be sized as a box, using width and height.
*
BoxComponent provides automatic box model adjustments for sizing and positioning and will work correctly
* within the Component rendering model.
*
A BoxComponent may be created as a custom Component which encapsulates any HTML element, either a pre-existing
* element, or one that is created to your specifications at render time. Usually, to participate in layouts,
* a Component will need to be a BoxComponent in order to have its width and height managed.
*
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({
autoEl: {
tag: 'img',
src: '/images/my-image.jpg'
}
});
* @constructor
* @param {Ext.Element/String/Object} config The configuration options.

* Each child Component with a flex property will be flexed either vertically (by a VBoxLayout)
* or horizontally (by an HBoxLayout) according to the item's relativeflex value
* compared to the sum of all Components with flex value specified. Any child items that have

Note: Although many components inherit this config option, not all will

If the browser is managing the height, be aware that resizes performed by the browser in response

/**
* @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:
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({

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:
The layout type to be used for this container. If not specified,
* a default {@link Ext.layout.ContainerLayout} will be created and used.
*
Valid layout type values are:
*
*
{@link Ext.layout.AbsoluteLayout absolute}
*
{@link Ext.layout.AccordionLayout accordion}
*
{@link Ext.layout.AnchorLayout anchor}
*
{@link Ext.layout.ContainerLayout auto}Default

If an added item is a config object, and not an instantiated Component, then the default properties are
* unconditionally applied. If the added item is an instantiated Component, then the default properties are
* applied conditionally so as not to override existing properties in the item.
*
If the defaults option is specified as a function, then the function will be called using this Container as the
* scope (this reference) and passing the added item as the first parameter. Any resulting object
* from that call is then applied to the item as default properties.
*
For example, to automatically apply padding to the body of each of a set of
* contained {@link Ext.Panel} items, you could pass: defaults: {bodyStyle:'padding:15px'}.
*
Usage:

/**
* @class Ext.layout.FitLayout
* @extends Ext.layout.ContainerLayout
*
This is a base class for layouts that contain a single item that automatically expands to fill the layout's
* container. This class is intended to be extended or created via the layout:'fit' {@link Ext.Container#layout}
* config, and should generally not need to be created directly via the new keyword.
*
FitLayout does not have any direct config options (other than inherited ones). To fit a panel to a container
* using FitLayout, simply set layout:'fit' on the container and add a single panel to it. If the container has
* multiple panels, only the first one will be displayed. Example usage:
*
var p = new Ext.Panel({
title: 'Fit Layout',
layout:'fit',
items: {
title: 'Inner Panel',
html: '<p>This is the inner panel content</p>',
border: false
}
});
This layout manages multiple child Components, each fitted to the Container, where only a single child Component can be
* visible at any given time. This layout style is most commonly used for wizards, tab implementations, etc.
* 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.
};

title: 'Example Wizard',
layout:'card',
activeItem: 0, // make sure the active item is set on the container config!

/**
* @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:
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 2',
columnWidth: .6
},{
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
},{
title: 'Column 2',
columnWidth: .8
},{
title: 'Column 3',
columnWidth: .2
}]

Any child items with a region of west or east must have width defined
* (an integer representing the number of pixels that the region should take up).
*
Any child items with a region of north or south must have height defined.
*
The regions of a BorderLayout are fixed at render time and thereafter, its child Components may not be removed or added. To add/remove
* Components within a BorderLayout, have them wrapped by an additional Container which is directly
* managed by the BorderLayout. If the region is to be collapsible, the Container used directly

* @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:
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:
*
// Required if showing validation messages

// you should usually use a FormPanel to also get its form functionality

* @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
// with some spanning included. The basic layout will be:
// +--------+-----------------+
// | A | B |
// | |--------+--------|
// | | C | D |
// +--------+--------+--------+
var table = new Ext.Panel({
title: 'Table Layout',
layout:'table',
defaults: {
// applied to each contained panel
bodyStyle:'padding:20px'
},
layoutConfig: {
// The total column count must be specified here
columns: 3
},
items: [{
html: '<p>Cell A content</p>',
rowspan: 2
},{
html: '<p>Cell B content</p>',
colspan: 2
},{
html: '<p>Cell C content</p>',
cellCls: 'highlight'
},{
html: '<p>Cell D content</p>'
}]
});
*/

This class is intended to be extended or created via the {@link Ext.Container#layout layout}

This property may also be specified as a string containing

If there is only one value, it applies to all sides.

If there are two values, the top and bottom borders are set to the
* first value and the right and left are set to the second.
*
If there are three values, the top is set to the first value, the left

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}.
This Element is used to house the {@link #title} and {@link #tools}

By default, the Default element in the table below will be used for the html markup to
* create a child element with the commensurate Default class name (baseCls will be
* replaced by {@link #baseCls}):
*
* Panel Default Default Custom Additional Additional
* Element element class element class style
* ======== ========================== ========= ============== ===========
* {@link #header} div {@link #baseCls}+'-header' {@link #headerCfg} headerCssClass headerStyle
* {@link #bwrap} div {@link #baseCls}+'-bwrap' {@link #bwrapCfg} bwrapCssClass bwrapStyle

* + {@link #footer} div {@link #baseCls}+'-footer' {@link #footerCfg} footerCssClass footerStyle
*
*
Configuring a Custom element may be used, for example, to force the {@link #body} Element
* to use a different form of markup than is created by default. An example of this might be
* to {@link Ext.Element#createChild create a child} Panel containing a custom content, such as
* a header, or forcing centering of all Panel content by having the body be a <center>
* element:
*
new Ext.Panel({
title: 'Message Title',
renderTo: Ext.getBody(),
width: 200, height: 130,
bodyCfg: {
tag: 'center',
cls: 'x-panel-body', // Default class not applied if Custom element specified
html: 'Message'
},
footerCfg: {
tag: 'h2',
cls: 'x-panel-footer', // same as the Default class
html: 'footer html'
},
footerCssClass: 'custom-footer', // additional css class, see {@link Ext.element#addClass addClass}
footerStyle: 'background-color:red' // see {@link #bodyStyle}
});
*
*
The example above also explicitly creates a {@link #footer} with custom markup and
* styling applied.

handler : Function
Required. The function to
* call when clicked. Arguments passed are:
*
event : Ext.EventObject
The click event.
*
toolEl : Ext.Element
The tool Element.
*
panel : Ext.Panel
The host Panel
*
tc : Object
The tool configuration object
*
*
stopEvent : Boolean
Defaults to true. Specify as false to allow click event to propagate.
*
scope : Object
The scope in which to call the handler.
*
qtip : String/Object
A tip string, or
* a config argument to {@link Ext.QuickTip#register}
*
hidden : Boolean
True to initially render hidden.
*
on : Object
A listener config object specifiying
* event listeners in the format of an argument to {@link #addListener}
*
*
Note that, apart from the toggle tool which is provided when a panel is collapsible, these
* tools only provide the visual button. Any required functionality must be provided by adding

An updateable progress bar component. The progress bar supports two different modes: manual and automatic.

*
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.

*
Property Type Description
---------- ------------ ----------------------------------------------------------------------
duration Number The length of time in milliseconds that the progress bar should
run before resetting itself (defaults to undefined, in which case it
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
not specified, the default for the class is used.
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).
*
* Example usage:
*
var p = new Ext.ProgressBar({
renderTo: 'my-el'
});
//Wait for 5 seconds, then update the status el (progress bar will auto-reset)
p.wait({
interval: 100, //bar will move fast!
duration: 5000,
increment: 15,
text: 'Updating...',
scope: this,
fn: function(){

//Or update indefinitely until some async action completes, then reset manually
