/**
|
|
* @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>

|
|
* the scope of 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 <tt>'x-tab'</tt>. 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 <tt>autoTabs</tt> config (as opposed to passing individual tab configs in the TabPanel's
|
|
* {@link #items} collection), you must use <tt>{@link #applyTo}</tt> to correctly use the specified <tt>id</tt>
|
|
* 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>
