Thanks for that - my ui is now responsive What is the correct way to stop my thread running? I tried m_thread->exit() but it still continues

Your moveToThread will fail, because GeneratorThread (confusing name for what seems to be a worker class?) has a parent. That causes that your worker is not in a different thread at all, but blocking your main thread instead.
