Maybe.. this whole widget painting thingy is really new to me :-( ....

As far as I remember each widget had to be implemented/customized to be 
ready to use with Goya.. That's just too much work for my usecase.
I've now switched over to a much simler approach with nearly the same 
effect:

QScrollArea + Buttons on the left for showing/hiding the widgets, on the 
right the widgets -- perfect for my usecase ^^ -- with the right icons 
and styles it will just fit :-)

Still: THANKS for your help :-)
