You can't. GUI elements can not work outside the main thread. If you
have things that need a separate thread send signals from the threads
run() method or post events which then get captured by the gui elements
(either via a slot or a customEvent() function) and then can update the
gui apropriately.

Also if you access variables in your thread class from multiple threads
you want to protect them against concurrent access, for example by using
QMutexLocker with a QMutex.
