That's why I *emphasized* the word *receiving* ;) In your case the emitting thread is your worker thread and the *receiving* thread is your "main" thread. And I am pretty sure your "main" thread as a QApplication object, on which you called exec(), right? (Just to make sure).

So yes, in your case your worker thread does *not* need a running event queue. So in case you do have QApplication::exec() called in your "main" thread I don't know why your slot is not being called. How do you figure out anyway? I guess you have some qDebug << "I am called." statement and made sure that stdout/err output is visible on some console (in case you're doing this on Windows)?

Cheers, Oliver
