+ * @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>
+ * </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>
