I think that's true -- in general. However, it is possible to subclass a QStyle, and make your own widget style in Python. You could dynamically determine which style to subclass, and then only re-implement the painting of QHeader to include mouse-over highlighting. There are KDE styles that have highlighting, for instance if you move the mouse over a button. > Why oh why did I ever think about leaving back-end library > development?
