[PySide] uncheck button after drag&drop

[Frank Rueter | OHUfx]

yeah, I just liked the name "sloppy click" :)
totally agree though, and I guess that's why I was asking for help.
I initially tried to read out how far the mouse is moving inside of the 
mouseMoveEvent but couldn't get it right.
I used:
setMouseTracking( True )
curPos = event.pos()

but curPos is not evaluated until after the mouse button is released the 
first time. That's why I implemented the drag event to access the 
coordinates through that. But, of course as you pointed out, I want to 
avoid the drag event until the mouse has moved a certain distance.

Do you have an example of how to read the cursor position in the 
mouseMoveEvent?

Cheers,
frank
