[PySide] Application.type doesn't exist in PySide2 anymore

[Frank Rueter | OHUfx]

Thanks for clarifying, I thought I was missing something.

I am now doing this to check for GUI vs batch mode:

    if isinstance(QtWidgets.QApplication.instance(),
    QtWidgets.QApplication):
         # running in GUI mode


in batch mode QApplication is of type QCoreApplication, so the above 
seems to be the solution.

Cheers,
frank
