17 * @extends Ext.Container
18 * <p>A specialized container representing the viewable application area (the browser viewport).</p>
19 * <p>The Viewport renders itself to the document body, and automatically sizes itself to the size of
20 * the browser viewport and manages window resizing. There may only be one Viewport created
21 * in a page. Inner layouts are available by virtue of the fact that all {@link Ext.Panel Panel}s
22 * added to the Viewport, either through its {@link #items}, or through the items, or the {@link #add}
23 * method of any of its child Panels may themselves have a layout.</p>
24 * <p>The Viewport does not provide scrolling, so child Panels within the Viewport should provide
25 * for scrolling if needed using the {@link #autoScroll} config.</p>
26 * <p>An example showing a classic application border layout:</p><pre><code>
31 html: '<h1 class="x-panel-header">Page Title</h1>',
40 // the west region might typically utilize a {@link Ext.tree.TreePanel TreePanel} or a Panel with {@link Ext.layout.AccordionLayout Accordion layout}
43 title: 'Title for Panel',
45 html: 'Information goes here',
51 title: 'Title for the Grid Panel',
56 // remaining grid configuration not shown ...
57 // notice that the GridPanel is added directly as the region
58 // it is not "overnested" inside another Panel
61 xtype: 'tabpanel', // TabPanel itself has no title
64 html: 'The first tab\'s content. Others may be added dynamically'
70 * Create a new Viewport
71 * @param {Object} config The config object
74 Ext.Viewport = Ext.extend(Ext.Container, {
76 * Privatize config options which, if used, would interfere with the
77 * correct operation of the Viewport as the sole manager of the
78 * layout of the document body.
