-/**
- * @class Ext.TabPanel
- * <p>A basic tab container. TabPanels can be used exactly like a standard {@link Ext.Panel}
- * for layout purposes, but also have special support for containing child Components
- * (<tt>{@link Ext.Container#items items}</tt>) that are managed using a
- * {@link Ext.layout.CardLayout CardLayout layout manager}, and displayed as separate tabs.</p>
- *
- * <b>Note:</b> By default, a tab's close tool <i>destroys</i> the child tab Component
- * and all its descendants. This makes the child tab Component, and all its descendants <b>unusable</b>. To enable
- * re-use of a tab, configure the TabPanel with <b><code>{@link #autoDestroy autoDestroy: false}</code></b>.
- *
- * <p><b><u>TabPanel header/footer elements</u></b></p>
- * <p>TabPanels use their {@link Ext.Panel#header header} or {@link Ext.Panel#footer footer} element
- * (depending on the {@link #tabPosition} configuration) to accommodate the tab selector buttons.
- * This means that a TabPanel will not display any configured title, and will not display any
- * configured header {@link Ext.Panel#tools tools}.</p>
- * <p>To display a header, embed the TabPanel in a {@link Ext.Panel Panel} which uses
- * <b><tt>{@link Ext.Container#layout layout:'fit'}</tt></b>.</p>
- *
- * <p><b><u>Tab Events</u></b></p>
- * <p>There is no actual tab class — each tab is simply a {@link Ext.BoxComponent Component}
- * such as a {@link Ext.Panel Panel}. However, when rendered in a TabPanel, each child Component
- * can fire additional events that only exist for tabs and are not available from other Components.
- * These events are:</p>
- * <div><ul class="mdetail-params">
- * <li><tt><b>{@link Ext.Panel#activate activate}</b></tt> : Fires when this Component becomes
- * the active tab.</li>
- * <li><tt><b>{@link Ext.Panel#deactivate deactivate}</b></tt> : Fires when the Component that
- * was the active tab becomes deactivated.</li>
- * <li><tt><b>{@link Ext.Panel#beforeclose beforeclose}</b></tt> : Fires when the user clicks on the close tool of a closeable tab.
- * May be vetoed by returning <code>false</code> from a handler.</li>
- * <li><tt><b>{@link Ext.Panel#close close}</b></tt> : Fires a closeable tab has been closed by the user.</li>
- * </ul></div>
- * <p><b><u>Creating TabPanels from Code</u></b></p>
- * <p>TabPanels can be created and rendered completely in code, as in this example:</p>
- * <pre><code>
-var tabs = new Ext.TabPanel({
- renderTo: Ext.getBody(),
- activeTab: 0,
- items: [{
- title: 'Tab 1',
- html: 'A simple tab'
- },{
- title: 'Tab 2',
- html: 'Another one'
- }]
-});
-</code></pre>
- * <p><b><u>Creating TabPanels from Existing Markup</u></b></p>
- * <p>TabPanels can also be rendered from pre-existing markup in a couple of ways.</p>
- * <div><ul class="mdetail-params">
- *
- * <li>Pre-Structured Markup</li>
- * <div class="sub-desc">
- * <p>A container div with one or more nested tab divs with class <tt>'x-tab'</tt> can be rendered entirely
- * from existing markup (See the {@link #autoTabs} example).</p>
- * </div>
- *
- * <li>Un-Structured Markup</li>
- * <div class="sub-desc">
- * <p>A TabPanel can also be rendered from markup that is not strictly structured by simply specifying by id
- * which elements should be the container and the tabs. Using this method tab content can be pulled from different
- * elements within the page by id regardless of page structure. For example:</p>
- * <pre><code>
-var tabs = new Ext.TabPanel({
- renderTo: 'my-tabs',
- activeTab: 0,
- items:[
- {contentEl:'tab1', title:'Tab 1'},
- {contentEl:'tab2', title:'Tab 2'}
- ]
-});
-
-// Note that the tabs do not have to be nested within the container (although they can be)
-<div id="my-tabs"></div>
-<div id="tab1" class="x-hide-display">A simple tab</div>
-<div id="tab2" class="x-hide-display">Another one</div>
-</code></pre>
- * Note that the tab divs in this example contain the class <tt>'x-hide-display'</tt> so that they can be rendered
- * deferred without displaying outside the tabs. You could alternately set <tt>{@link #deferredRender} = false </tt>
- * to render all content tabs on page load.
- * </div>
- *
- * </ul></div>

- * unactivated tabs will not be rendered, and will therefore not be submitted and will not be
- * available to either {@link Ext.form.BasicForm#getValues getValues} or

- * method).</p>
- * <p>This method is only possible when the markup is structured correctly as a container with nested divs
- * containing the class <tt>'x-tab'</tt>. To create TabPanels without these limitations, or to pull tab content

- * <p>There are a couple of things to note when using this method:<ul>
- * <li>When using the <tt>autoTabs</tt> config (as opposed to passing individual tab configs in the TabPanel's

- * as the tab container. The <tt>autoTabs</tt> method <em>replaces</em> existing content with the TabPanel
- * components.</li>
- * <li>Make sure that you set <tt>{@link #deferredRender}: false</tt> so that the content elements for each
- * tab will be rendered into the TabPanel immediately upon page load, otherwise they will not be transformed
- * until each tab is activated and will be visible outside the TabPanel.</li>
- * </ul>Example usage:</p>
- * <pre><code>
