Correct, QThread's affinity will be to the GUI thread (since that is where 
it was created). This means all AutoConnections to the QThread subclass's 
slots will be run in the main thread.

You do ;)

A small suggestion: change the class that you're working on to inherit 
directly from QObject instead. Then instantiate it and a QThread, move your 
object to the newly created (but completely disjoint) thread, and enjoy.

Essentially, something like this (overly simplified for the author's 
convenience :P):

     MyObject *obj = new MyObject(...);
     QThread *thread = new QThread(...);
     connect(...);
     obj->moveToThread(thread);
     thread->start();
