2 nested containers and can also be used as expected as a Viewport layout to center the page layout.</p>
3 <p>As a subclass of FitLayout, CenterLayout expects to have a single child panel of the container that uses
4 the layout.  The layout does not require any config options, although the child panel contained within the
5 layout must provide a fixed or percentage width.  The child panel's height will fit to the container by
6 default, but you can specify <tt>autoHeight:true</tt> to allow it to autosize based on its content height.
7 Example usage:</p>
8 <pre><code><i>// The content panel is centered <b>in</b> the container</i>
9 <b>var</b> p = <b>new</b> Ext.Panel({
10     title: <em>'Center Layout'</em>,
11     layout: <em>'ux.center'</em>,
12     items: [{
13         title: <em>'Centered Content'</em>,
14         width: <em>'75%'</em>,
15         html: <em>'Some content'</em>
16     }]
17 });
18
19 <i>// If you leave the title blank and specify no border</i>
20 <i>// you<em>'ll create a non-visual, structural panel just</i>
21 <i>// <b>for</b> centering the contents <b>in</b> the main container.</i>
22 <b>var</b> p = <b>new</b> Ext.Panel({
23     layout: '</em>ux.center<em>',
24     border: false,
25     items: [{
26         title: '</em>Centered Content<em>',
27         width: 300,
28         autoHeight: true,
29         html: '</em>Some content<em>'
