Ok, I solved most of my problems using grabKeyboard()/releaseKeyboard() 
methods.

I still have an issue: when I hold down a key, once the repeat starts, I 
receive both KeyPressed and KeyReleased events. This is a different 
behaviour as PyGTK, where I only received the key-pressed-event while 
holding it down, and the key-release-event when I release the key.

Is there a way to do this in PyQt? I want to start the motor head when I 
press the key, and stop it when I release the key. Now, it does not work, 
as the motor is started/stopped too quickly (which is not very good)...
