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.

GUI work is what I do for a hobby; my living is in coding the kernel
of a multi-agent system...
