99 * String to display while loading.
103 * @cfg {String} region
104 * Region to render component to (defaults to center)
110 * A single item array - the first element is the root of the tree..
111 * It's done this way to stay compatible with the Xtype system...
117 * The method that retuns the tree of parts that make up this compoennt
124 * render element to dom or tree
