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 - * ({@link Ext.Container#items items}) that are managed using a - * {@link Ext.layout.CardLayout CardLayout layout manager}, and displayed as separate tabs.
- * - * Note: By default, a tab's close tool destroys the child tab Component - * and all its descendants. This makes the child tab Component, and all its descendants unusable. To enable - * re-use of a tab, configure the TabPanel with{@link #autoDestroy autoDestroy: false}
.
- *
- * TabPanel header/footer elements
- *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}.
- *To display a header, embed the TabPanel in a {@link Ext.Panel Panel} which uses - * {@link Ext.Container#layout layout:'fit'}.
- * - *Tab Events
- *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:
- *false
from a handler.Creating TabPanels from Code
- *TabPanels can be created and rendered completely in code, as in this example:
- *
-var tabs = new Ext.TabPanel({
- renderTo: Ext.getBody(),
- activeTab: 0,
- items: [{
- title: 'Tab 1',
- html: 'A simple tab'
- },{
- title: 'Tab 2',
- html: 'Another one'
- }]
-});
-
- * Creating TabPanels from Existing Markup
- *TabPanels can also be rendered from pre-existing markup in a couple of ways.
- *A container div with one or more nested tab divs with class 'x-tab' can be rendered entirely - * from existing markup (See the {@link #autoTabs} example).
- *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:
- *
-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>
-
- * 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} = false
- * to render all content tabs on page load.
- * {@link Ext.layout.CardLayout#layoutOnCardChange layoutOnCardChange}
.

- *Note: leaving deferredRender as true means that the content - * within an unactivated tab will not be available.
