+/**
+ * @class Ext.ux.layout.CenterLayout
+ * @extends Ext.layout.FitLayout
+ * This is a very simple layout style used to center contents within a container. This layout works within
+ * nested containers and can also be used as expected as a Viewport layout to center the page layout.
+ * As a subclass of FitLayout, CenterLayout expects to have a single child panel of the container that uses
+ * the layout. The layout does not require any config options, although the child panel contained within the
+ * layout must provide a fixed or percentage width. The child panel's height will fit to the container by
+ * default, but you can specify autoHeight:true to allow it to autosize based on its content height.
+ * Example usage:
+ *
+// The content panel is centered in the container
+var p = new Ext.Panel({
+ title: 'Center Layout',
+ layout: 'ux.center',
+ items: [{
+ title: 'Centered Content',
+ width: '75%',
+ html: 'Some content'
+ }]
+});
+
+// If you leave the title blank and specify no border
+// you'll create a non-visual, structural panel just
+// for centering the contents in the main container.
+var p = new Ext.Panel({
+ layout: 'ux.center',
+ border: false,
+ items: [{
+ title: 'Centered Content',
+ width: 300,
+ autoHeight: true,
+ html: 'Some content'
+ }]
+});
+
