Hey Simon,
>From what I understand I'd say that by importing Nuke, the Qt's
QApplication is instancied with Nuke.
So when you do:
app = QApplication(sys.argv)
It shows that error.
Maybe you could test if QApplication is already instancied ?
app = QApplication.instance()
if app is None:
app = QApplication(sys.argv)
If yes that mean Nuke is the main app so you don't have to create it.
Not sure if you want Nuke to run as the main app tho...
These are just ideas as I never experienced that situation.
Cheers,
Justin
