[PyQt] Scroll-by-row in QTableView using mouse wheel

[Benno Dielmann]

Hi there, 

I'd like my QTableView to scroll one row at a time when using the mouse wheel. 
On my KDE 3.5.9 it always scrolls three rows at once. 

Is there any convenient way I missed to adjust this or do I have to subclass 
QTableView, catch the MouseWheel event and do the scrolling by myself?

Thanks in advance for any hints on this, 

Benno.
