Christian, you're dead right about accessing QWidgets: When
programming Qt one should definitely stay away from manipulating GUI
related QObjects from non-main threads. The best practice is to
connect signals in QObjects belonging to other threads to slots in
QWidgets. All attempts to circumvent this approach I know of failed
dramatically.
