[PyKDE] setMouseTracking

[Frederick Polgardy Jr]

This is one of the strange cases in Qt where you don't use signals and 
slots.  You subclass your QWidget/QCanvas and provide a mouseMoveEvent() 
handler.  (Actually there are a bunch more: check out the QWidget header 
file.)  In fact, I'm guessing you can rename your contentsMouseMove() 
method to mouseMoveEvent(), and it will magically start working. :)
