No, unfortunately that alternative didn't occur to me until you pointed it out just now. It sounds like a very suitable environment for what I'm doing. I have implemented a lot of functionality in the past two weeks and switching to QGraphicsView now would basicly mean redoing everything from the start and finding solutions for all the little problems again that reappear in new forms. I'm certainly not the kind of guy who holds on to the crap he has made in the past if there is a much nicer solution. But I also don't get paid to play around. I have to spend some time thinking my way through it and try to estimate how much time the refactoring would take...and how I can do it secretly of course, because no boss would ever allow this.
