Get rid of the new operator, though. IMO there's no excuse for a GUI framework to expose users to unmanaged resources.

Hmm, do you know of a C++ GUI framework that gets this right?

Just curious [Brian Braatz] The problem is handling the "dual lifetimes" of "system" GUI objects and C++ objects.

BeOS is the only system I know that does not have this issue, because they extended C++ in such a way so that when you "create" a C++ window object- you now have a window. In frameworks like MFC, they have to internally track a windows resources "object" that the system understands as the gui object. You will always need a dynamic nature to things, but one could take a Rogue Wave approach here and hide all those new's behind accessor type objects which pass around by value and internally hold something like a boost::shared_ptr<> (my 2 cents) Brian
