In addition, Tix augments Tk by providing:
wm command
for reparenting windows.
Some of these widgets are implemented by Tix in ``C'', such as the HList and Tree widgets, but in fact, very few new widgets at the "C" level are introduced by Tix; most are compound widgets of existing Tk widgets. They are all created using the simple object oriented programming (OOP) framework for writing mega-widgets called the Tix Intrinsics.
