OK, so I am not doing any desktop app development this days but if I will do I will not write any special code for GNOME. > GTK is not a cross platform toolkit like Qt where it tries to draw everything with native widgets Just a correction, Qt does not use native widget, they have code that will adapt and paint the thigns too look and work as native widgets, so for example they have button groups that when you use it say for OK-Cancel buttons it will change it to Cancel-OK on different platforms (some platforms have the order reversed). Also Qt will paint the OK/Cancel button icons on KDE but not on Windows/GNOME . So in fact Qt devs put the effort in and wrote code and themes to get things look native, use the native file dialogs, use the native notifications, system tray, the native paths etc (not ike the other toolkit that doesn't care about integration, theming and configuration)
