- * classes in Ext. It simply renders all child Components into the Container, performing no sizing or
- * positioning services. To utilize a layout that provides sizing and positioning of child Components,
- * specify an appropriate <tt>{@link Ext.Container#layout layout}</tt>.</p>
* <p>This class is intended to be extended or created via the <tt><b>{@link Ext.Container#layout layout}</b></tt>
