 * when creating a full, nested config object for a complete Ext page.</p>
 * <p>A child Component may be specified simply as a <i>config object</i>
 * as long as the correct <code>{@link Ext.Component#xtype xtype}</code> is specified so that if and when the Component
 * needs rendering, the correct type can be looked up for lazy instantiation.</p>

/**
 * @class Ext.Container
 * @extends Ext.BoxComponent
 * <p>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.</p>
 *
 * <p>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
 * <code><b>{@link Ext.Component#autoEl autoEl}</b></code> config option. This is a useful technique when creating
 * embedded {@link Ext.layout.ColumnLayout column} layouts inside {@link Ext.form.FormPanel FormPanels}
 * for example.</p>
 *
 * <p>The code below illustrates both how to explicitly create a Container, and how to implicitly
 * create one using the <b><code>'container'</code></b> xtype:<pre><code>
// 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 &lt;DIV> element.
    items: [{
        items: {
            xtype: 'datefield',
            name: 'startDate',
            fieldLabel: 'Start date'
        }
    }, {
        items: {
            xtype: 'datefield',
            name: 'endDate',
            fieldLabel: 'End date'
        }
    }]
});</code></pre></p>
 *
 * <p><u><b>Layout</b></u></p>
 * <p>Container classes delegate the rendering of child Components to a layout
 * manager class which must be configured into the Container using the
 * <code><b>{@link #layout}</b></code> configuration property.</p>
 * <p>When either specifying child <code>{@link #items}</code> 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
 * <b><code>{@link #layout}</code></b> 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 <b>does not apply any sizing</b> at all.</p>
 * <p>A common mistake is when a developer neglects to specify a
 * <b><code>{@link #layout}</code></b> (e.g. widgets like GridPanels or
 * TreePanels are added to Containers for which no <code><b>{@link #layout}</b></code>
 * 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.</p>
 * <p>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:<pre><code>
//  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);
 * </code></pre></p>
 * <p>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.
 * <p><b><u>Overnesting is a common problem</u></b>.
 * An example of overnesting occurs when a GridPanel is added to a TabPanel
 * by wrapping the GridPanel <i>inside</i> a wrapping Panel (that has no
 * <code><b>{@link #layout}</b></code> specified) and then add that wrapping Panel
 * to the TabPanel. The point to realize is that a GridPanel <b>is</b> a
 * Component which can be added directly to a Container. If the wrapping Panel
 * has no <code><b>{@link #layout}</b></code> configuration, then the overnested
 * GridPanel will not be sized as expected.<p>
 *
 * <p><u><b>Adding via remote configuration</b></u></p>
 *
 * <p>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:
 * </p><pre><code>
// 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");
    }
});
</code></pre>
 * <p>The server script needs to return an executable Javascript statement which, when processed
 * using <code>eval()</code>, will return either a config object with an {@link Ext.Component#xtype xtype},
 * or an instantiated Component. The server might return this for example:</p><pre><code>
(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'
        },

            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
})();
</code></pre>
 * <p>When the above code fragment is passed through the <code>eval</code> function in the success handler
 * of the Ajax request, the code is executed by the Javascript processor, and the anonymous function

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

    },{
        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',

 * @class Ext.layout.BorderLayout

 * {@link Ext.layout.BorderLayout.Region#BorderLayout.Region regions} and built-in
 * {@link Ext.layout.BorderLayout.Region#collapsible expanding and collapsing} of regions.</p>
 * <p>This class is intended to be extended or created via the <tt>layout:'border'</tt>
 * {@link Ext.Container#layout} config, and should generally not need to be created directly
 * via the new keyword.</p>
 * <p>BorderLayout does not have any direct config options (other than inherited ones).
 * All configuration options available for customizing the BorderLayout are at the
 * {@link Ext.layout.BorderLayout.Region} and {@link Ext.layout.BorderLayout.SplitRegion}
 * levels.</p>
 * <p>Example usage:</p>
 * <pre><code>

 * <p><b><u>Notes</u></b>:</p><div class="mdetail-params"><ul>
 * <li>Any container using the BorderLayout <b>must</b> have a child item with <tt>region:'center'</tt>.
 * The child item in the center region will always be resized to fill the remaining space not used by
 * the other regions in the layout.</li>
 * <li>Any child items with a region of <tt>west</tt> or <tt>east</tt> must have <tt>width</tt> defined
 * (an integer representing the number of pixels that the region should take up).</li>
 * <li>Any child items with a region of <tt>north</tt> or <tt>south</tt> must have <tt>height</tt> defined.</li>
 * <li>The regions of a BorderLayout are <b>fixed at render time</b> and thereafter, its child Components may not be removed or added</b>.  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
 * by the BorderLayout manager should be a Panel.  In the following example a Container (an Ext.Panel)
 * is added to the west region:
 * <div style="margin-left:16px"><pre><code>

wrc.{@link Ext.Container#doLayout doLayout}();

 * @class Ext.layout.FormLayout
 * @extends Ext.layout.AnchorLayout
 * <p>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.</p>
 *
 * <p>This layout manager is used when a Container is configured with the <tt>layout:'form'</tt>
 * {@link Ext.Container#layout layout} config option, and should generally not need to be created directly
 * via the new keyword. See <tt><b>{@link Ext.Container#layout}</b></tt> for additional details.</p>
 *
 * <p>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.</p>
 *
 * <p>A {@link Ext.Container Container} <i>using</i> the FormLayout layout manager (e.g.
 * {@link Ext.form.FormPanel} or specifying <tt>layout:'form'</tt>) can also accept the following
 * layout-specific config properties:<div class="mdetail-params"><ul>
 * <li><b><tt>{@link Ext.form.FormPanel#hideLabels hideLabels}</tt></b></li>
 * <li><b><tt>{@link Ext.form.FormPanel#labelAlign labelAlign}</tt></b></li>
 * <li><b><tt>{@link Ext.form.FormPanel#labelPad labelPad}</tt></b></li>
 * <li><b><tt>{@link Ext.form.FormPanel#labelSeparator labelSeparator}</tt></b></li>
 * <li><b><tt>{@link Ext.form.FormPanel#labelWidth labelWidth}</tt></b></li>
 * </ul></div></p>
 *
 * <p>Any Component (including Fields) managed by FormLayout accepts the following as a config option:
 * <div class="mdetail-params"><ul>
 * <li><b><tt>{@link Ext.Component#anchor anchor}</tt></b></li>
 * </ul></div></p>
 *
 * <p>Any Component managed by FormLayout may be rendered as a form field (with an associated label) by
 * configuring it with a non-null <b><tt>{@link Ext.Component#fieldLabel fieldLabel}</tt></b>. Components configured
 * in this way may be configured with the following options which affect the way the FormLayout renders them:
 * <div class="mdetail-params"><ul>
 * <li><b><tt>{@link Ext.Component#clearCls clearCls}</tt></b></li>
 * <li><b><tt>{@link Ext.Component#fieldLabel fieldLabel}</tt></b></li>
 * <li><b><tt>{@link Ext.Component#hideLabel hideLabel}</tt></b></li>
 * <li><b><tt>{@link Ext.Component#itemCls itemCls}</tt></b></li>
 * <li><b><tt>{@link Ext.Component#labelSeparator labelSeparator}</tt></b></li>

 * @class Ext.layout.TableLayout
 * @extends Ext.layout.ContainerLayout
 * <p>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.</p>
 * <p>Note that when creating a layout via config, the layout-specific config properties must be passed in via
 * the {@link Ext.Container#layoutConfig} object which will then be applied internally to the layout.  In the
 * case of TableLayout, the only valid layout config property is {@link #columns}.  However, the items added to a
 * TableLayout can supply the following table-specific config properties:</p>
 * <ul>
 * <li><b>rowspan</b> Applied to the table cell containing the item.</li>
 * <li><b>colspan</b> Applied to the table cell containing the item.</li>
 * <li><b>cellId</b> An id applied to the table cell containing the item.</li>
 * <li><b>cellCls</b> A CSS class name added to the table cell containing the item.</li>
 * </ul>
 * <p>The basic concept of building up a TableLayout is conceptually very similar to building up a standard
 * HTML table.  You simply add each panel (or "cell") that you want to include along with any span attributes
 * specified as the special config properties of rowspan and colspan which work exactly like their HTML counterparts.
 * Rather than explicitly creating and nesting rows and columns as you would in HTML, you simply specify the
 * total column count in the layoutConfig and start adding panels in their natural order from left to right,
 * top to bottom.  The layout will automatically figure out, based on the column count, rowspans and colspans,
 * how to position each panel within the table.  Just like with HTML tables, your rowspans and colspans must add
 * up correctly in your overall layout or you'll end up with missing and/or extra cells!  Example usage:</p>
 * <pre><code>
// This code will generate a layout table that is 3 columns by 2 rows
// with some spanning included.  The basic layout will be:
// +--------+-----------------+
// |   A    |   B             |
// |        |--------+--------|
// |        |   C    |   D    |

/**
 * @class Ext.Panel
 * @extends Ext.Container
 * <p>Panel is a container that has specific functionality and structural components that make
 * it the perfect building block for application-oriented user interfaces.</p>
 * <p>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.</p>
 * <p>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 <code><b>{@link Ext.Container#layout layout}</b></code> 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 <b>does not apply any sizing</b>
 * at all.</p>
 * <p>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).</p>
 * <p>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}.</p>

     * Initiates an auto-updating progress bar.  A duration can be specified, in which case the progress

     * be manually cleared by calling {@link #reset}.  The wait method accepts a config object with
     * the following properties:
     * <pre>
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).
</pre>
         *

   text: 'Updating...',

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