/**
* @class Ext.TabPanel
* <p>A basic tab container. Tab panels can be used exactly like a standard {@link Ext.Panel} for layout
* purposes, but also have special support for containing child Panels that get automatically converted into tabs.</p>
* <p>There is no actual tab class — each tab is simply an {@link Ext.Panel}. However, when rendered in a
* TabPanel, each child Panel can fire additional events that only exist for tabs and are not available to other
* Panels. These are:</p>
* <ul>
* <li><b>activate</b>: Fires when this Panel becomes the active tab.
* <div class="mdetail-params">
* <strong style="font-weight: normal;">Listeners will be called with the following arguments:</strong>
* <ul><li><code>tab</code> : Panel<div class="sub-desc">The tab that was activated</div></li></ul>
* </div></li>
* <li><b>deactivate</b>: Fires when this Panel that was the active tab becomes deactivated.
* <div class="mdetail-params">
* <strong style="font-weight: normal;">Listeners will be called with the following arguments:</strong>
* <ul><li><code>tab</code> : Panel<div class="sub-desc">The tab that was deactivated</div></li></ul>
* </div></li>
* </ul>
* <p>There are several methods available for creating TabPanels. The output of the following examples should be
* exactly the same. The tabs 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'
}]
});
</pre></code>
* <p>TabPanels can also be rendered from markup in a couple of ways. See the {@link #autoTabs} example for
* rendering entirely from markup that is already structured correctly as a TabPanel (a container div with
* one or more nested tab divs with class 'x-tab'). You can also render 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. Note
* that the tab divs in this example contain the class 'x-hide-display' so that they can be rendered deferred
* without displaying outside the tabs. You could alternately set {@link #deferredRender} to false to render all
* content tabs on page load. For example:
* <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>
</pre></code>

* the container element only (so that multiple tab panels from markup can be supported via this method).</p>
* <p>This method is only possible when the markup is structured correctly as a container with nested
* divs containing the class 'x-tab'. To create TabPanels without these limitations, or to pull tab content from
* other elements on the page, see the example at the top of the class for generating tabs from markup.</p>
* <p>There are a couple of things to note when using this method:<ul>
* <li>When using the autoTabs config (as opposed to passing individual tab configs in the TabPanel's
* {@link #items} collection), you must use {@link #applyTo} to correctly use the specified id as the tab container.
* The autoTabs method <em>replaces</em> existing content with the TabPanel components.</li>
* <li>Make sure that you set {@link #deferredRender} to false 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>
var tabs = new Ext.TabPanel({
applyTo: 'my-tabs',
activeTab: 0,
deferredRender: false,
autoTabs: true
});
// This markup will be converted to a TabPanel from the code above
<div id="my-tabs">
<div class="x-tab" title="Tab 1">A simple tab</div>
<div class="x-tab" title="Tab 2">Another one</div>
