This way you have native look and feel and also for embedded targets a UI that can look anyway you want it to. Luke.

Again, see wxWidgets. They also target X11 for targets which only support that. Luke.

The look-and-feel should/could propagate up the layers, provided the design supports look-and-feel management. IMO it should. However, weighting look-and-feel and an ability to have a standard library, I would say that I am ready to sacrifice look-and-feel. After all the "look-and-feel" of tasking, I/O etc is not one of UNIX or Windows. I would not shed tears about that. Further, for good or bad, there is not that many differences as it was before. Today Linux tries to mimic Windows. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de

Surely you meant Win32 there? No, I think Luke meant Gtk+.
