Hmm...  How about a window with a hetrogeneous collection of buttons, sliders,
text displays, etc, all of which respond to "redraw" and "is the mouse
over you"?  How about in GROPE (my project) in which each window has a
hetrogeneous collection of graphical Estelle objects (modules, channels,
states, transitions, queues, etc) which all respond to "redraw", "scale
to parent", "select good default graphics", "is the mouse over you", and
so on?  I have also done simulation code where collections of hetrogenous
objects are in "shopping carts" which all respond to "what is your price"
and such things.  Naturally, if all you have is a hammer, you never see
the need for a screw.          -- Darren
