Right. The QT developers have been working for years to get their
controls to quack like the native ones, even though they aren't
native. They started from controls that looked and worked the same on
all platforms and have been trying to get them to play nicely with the
environment they're running in. wx has been working from the opposite
direction- they started with wrapping the native API and have been
working on getting their API to make programs come out the same even
when using different underlying toolkits. When I used wx about 5 years
ago, some of the layout got messed up when we first ran the program
(developed on Linux/GTK+)  on a Mac because of some differences
between how Carbon and GTK+ draw their controls.
