[PyQt] Coordinates in QScrollarea

[georg at muenster.de]

Hello,
I'm using a QScrollArea as CentralWidget to display an SVG-file. Now I
want to interact with the drawn image and select items via
MousePressEvent. Only problem is that the position of the mouse is
changing when I use the scrollbar. Does anybody know a solution? I'm
new to python and I hope that I didn't oversee any obvious
solutions...
Thanks!
Georg
