Thanks for your answer! It seems I completely misunderstood Signal/Slot. But know: What's the difference to ObserverPattern (e.g. like in Events/Listeners) then? Or is it that just another name because QT has it in every QObject? (Sorry, I stopped reading your Link at "The Meta Object Compiler" where too much C++ happend...)
