[PySide] uncheck button after drag&drop

[Frank Rueter | OHUfx]

Sweet, the setDown() method was what I needed, thanks!
It's a little disapointing that the right and middle mouse click events 
don't seem to work on a mac though.

I guess in that case I will have to make sure that the mousePressEvent 
isn't called when the button is dragged. Is there an elegant way to set 
some sort of threshold or check if the button was moved a certain 
distance between the mouseDown and mouseUp events, and if so, don't 
trigger the mousePressEvent? Will have a play, I might have just 
answered my own question :-D

Cheers,
frank
