Strictly speaking, I am not sure these are OSG questions as much as they are Qt questions, but since I am a developer an OSG/Qt app myself, I will share what little I know.
I know that reparenting under some windowing systems can invalidate window IDs, so that might be related to your "BadWindow" errors. You would have to check with your Qt documentation and your windowing system documentation to be sure (that is, if it is documented). You might have tried this already, but if not, then try setting the OSG adapter widget's parent in the constructor, and reparenting the parent widget, instead of the OSG adapter widget. I cannot seem to find where I found this problem documented; you might start your search with winId, and go from there. As to the "Exit" problem you describe, look into overriding the protected virtual closeEvent function on your main window. Decide whether or not to accept the event; if you accept, have closeEvent inform the app to closeAllWindows at an appropriate time. You should probably wait until the main window actually closes before calling closeAllWindows on the app, since not waiting can cause problems (I do not recall if it is a recursion problem, or a "you closed this already" problem). I hope this helps... D.J.
