* @class Ext.layout.FitLayout
* @extends Ext.layout.ContainerLayout
* <p>This is a base class for layouts that contain <b>a single item</b> that automatically expands to fill the layout's
* container. This class is intended to be extended or created via the <tt>layout:'fit'</tt> {@link Ext.Container#layout}
* config, and should generally not need to be created directly via the new keyword.</p>
* <p>FitLayout does not have any direct config options (other than inherited ones). To fit a panel to a container
* using FitLayout, simply set layout:'fit' on the container and add a single panel to it. If the container has
* multiple panels, only the first one will be displayed. Example usage:</p>
* <pre><code>
var p = new Ext.Panel({
title: 'Fit Layout',
layout:'fit',
items: {
title: 'Inner Panel',
html: '<p>This is the inner panel content</p>',
border: false
}
});
</code></pre>
