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