I was not sure about that either, but found this interesting document, which states that GUI objects can only be used from the main thread:

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.
