Hi Alban, yes this works. I'll commit this as well. We may have to discuss, if this doesn't break anything else, e.g. if someone wants to use the driver in her Qt application, but as I understand it will initQtApp() only called if there is no existing qt app (or at least the specific lines), so this should be not much trouble.
