Actually, Yong, I find "deep inheritance hierarchies" to be useful at
times. Of course they've been complicated - but each class only needs
to worry about its own implementation and the interface of its base
class. It all depends on what you need.
As for overriding the functions - that's one of the beauties of OO
programming. You call setSize() in the lowest class, and it processes
the request and passes it on to the parent. Of course, each setSize()
should have the same purpose - just each one performs whatever work is
needed on its own class.
P.S. Please don't top post. This group uses bottom posting as a
standard. Thanks.
