/**
* @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
