- * @class Ext.Viewport
- * @extends Ext.Container
- * <p>A specialized container representing the viewable application area (the browser viewport).</p>
- * <p>The Viewport renders itself to the document body, and automatically sizes itself to the size of
- * the browser viewport and manages window resizing. There may only be one Viewport created
- * in a page. Inner layouts are available by virtue of the fact that all {@link Ext.Panel Panel}s
- * added to the Viewport, either through its {@link #items}, or through the items, or the {@link #add}
- * method of any of its child Panels may themselves have a layout.</p>
- * <p>The Viewport does not provide scrolling, so child Panels within the Viewport should provide
- * for scrolling if needed using the {@link #autoScroll} config.</p>
- * <p>An example showing a classic application border layout:</p><pre><code>
- new Ext.Viewport({
- layout: 'border',
- items: [{
- region: 'north',
- html: '<h1 class="x-panel-header">Page Title</h1>',
- autoHeight: true,
- border: false,
- margins: '0 0 5 0'
- }, {
- region: 'west',
- collapsible: true,
- title: 'Navigation',
- width: 200
- // the west region might typically utilize a {@link Ext.tree.TreePanel TreePanel} or a Panel with {@link Ext.layout.AccordionLayout Accordion layout}
- }, {
- region: 'south',
- title: 'Title for Panel',
- collapsible: true,
- html: 'Information goes here',
- split: true,
- height: 100,
- minHeight: 100
- }, {
- region: 'east',
- title: 'Title for the Grid Panel',
- collapsible: true,
- split: true,
- width: 200,
- xtype: 'grid',
- // remaining grid configuration not shown ...
- // notice that the GridPanel is added directly as the region
- // it is not "overnested" inside another Panel
- }, {
- region: 'center',
- xtype: 'tabpanel', // TabPanel itself has no title
- items: {
- title: 'Default Tab',
- html: 'The first tab's content. Others may be added dynamically'
- }
- }]
- });
- </code></pre>
- * @constructor
- * Create a new Viewport
- * @param {Object} config The config object
- * @xtype viewport

- Ext.Viewport = Ext.extend(Ext.Container, {
- /*
- * Privatize config options which, if used, would interfere with the
- * correct operation of the Viewport as the sole manager of the
- * layout of the document body.
