[Kde-games-devel] K or Qt includes ?

[cantabile]

Hi,
Sorry if the question has been asked already (is there a faq somewhere
?) but I'm wondering about includes.
If I understand correctly, the Kde libraries are inherited from the Qt
libraries. Thus, KMainWindow is inherited from QMainWindow.

If this correct, is there any reason why I should use K libraries
instead of QT ? For example KToolbar or QToolBar ? Why ?

Thanks for your answers.
