Question about the __name__ variable in plugins

[pslacerda]

Why I need to use "pmg_tk.startup.XDrugPy" when testing for __name__ when loading plugins? I test for __name__ because I can't use pymol.Qt from command line scripts.

if __name__ in ["pymol", "pmg_tk.startup.XDrugPy"]:
    import pymol

    QWidget = pymol.Qt.QtWidgets.QWidget
    ...

Note: I'm using PyMOL 2.6 LTS.
