Tnx, Fredrik,

I think the QButtonGroup-solution will do fine... One problem though... 
I've constructed the buttons in Qtdesigner and named them pushButton1 
--> pushButton40. Since all the buttons are similar I constructed them 
by cutting and pasting... Problem is now that the id's do not seem to 
match the order of the buttons. Is there a way to set the id of a button 
in a buttongroup. The only thing I find is that you can specify the id 
when you add buttons through QButtonGroup.insert(QButton button, int 
id=-1)...

Tnx,

Tom
