4// Group that adds scrollbars so you can scroll around the area
5// covered by all the child widgets. For most uses you will make
6// a single child widget, this child may resize in it's layout()
7// and the scrollbars will adjust to match.
8//
9// Due to clipping problems no subclasses of Window may be used
10// as child widgets.
