[PySide] re-implementing setDown() for custom button

[Frank Rueter | OHUfx]

Hi,

to follow up my previous mail, I also just noticed that I have to 
re-implement the QAbstractButton's setDown() function to make sure my 
custom button doesn't stay down after a drag&drop action.

With a QPushButton I simply called self.setDown( False ) from inside the 
mouseMoveEvent, so now I'm trying to understand how to recreate this 
behaviour when using a custom paintEvent().

Any tips would be greatly appreciated.

Cheers,
frank
