Thanks, I should have checked this myself before asking..

However, there is one more thing I'd like to ask.
Is there a way to distinguish between actions were there actually was  
a change in checkbox state?
The same as in combo boxes and its signals: activated (int) and  
currentIndexChanged (int) ?
Or do I have to take care of this on my own?

Best wishes,
