HP Touchpad issues in Umbrello

[Robert Hairgrove]

The problem with controlling the zoom seems to stem from the fact that 
the underlying library (Qt) is interpreting touchpad gestures as mouse 
wheel events.

In the file umbrello/umlview.cpp I edited the overloaded wheelEvent() 
function to simply return at the top of the method. Up to now, this 
seems to work OK.

I would suggest that there should be a configuration option for this 
(i.e. whether or not to respond to wheel events)?
