You have completely misunderstood Qt. It is not its own windowing system,


Oh Really?,... Have you looked into the QT source code? I have, and I have the deep pain of using it a few years ago to develop a so called "cross platform application".

About all that QT uses of the native operating system is a window frame. Thats it, period. It calls the native operating system to create a window frame, then it has a pixbuff that it draws everything to, then the pixbuff is displayed in the window frame. QT uses its own "theming engine" to render controls. This is perfectly fine on Linux where QT IS THE NATIVE TOOLKIT, but bad on Windows, and an absolute disaster on the Mac.

We ended up scrapping the entire QT effort because the applications felt alien on the Windows and Mac, and ended up re-writting the UI with C# on Windows, and Cocoa on the Mac. This is the only way to write decent cross platform apps, and not short change your users: a cross platform core logic, in c++, and NATIVE UIs in C# and Cocoa.
