Counter-intuitive behavior of QThreads signals/slots

[jacek]

Upon examining the Qt documentation, I found only a single line that explains this behavior:[...]

You will have to read that document once more. The paragraph that explains this behavior is:

Like other objects, QThread objects live in the thread where the object was created -- not in the thread that is created when QThread::run() is called. It is generally unsafe to provide slots in your QThread subclass, unless you protect the member variables with a mutex.

Instead of subclassing QThread, put a QObject subclass inside the thread and all connections will behave as you expect.

Indeed I will, I missed that part completely. Thanks for pointing it out.
