   TODO list for knotebk:
   ----------------------

 - Better resizing for KTabBar.
   If scrolled it only rezises when width() >= tabbar->width().

 - Perhaps inherit KTabBar from QTabBar instead of having a QWidget with a QTabBar.
   Just couldn't figure out how. Suggestions are welcome!

 - Better handling of disabled tabs and pages.

 - The drawing isn't very nice in Win95 style (well, too bad)
