Success !!!
uiFileName = self.get_uiFileName(config)
with importlib.resources.path('nvfieldcap.resources.ui',
uiFileName) as uifilename:
uifilename = uifilename.as_posix()
class Filename_Folder_Widget(QtWidgets.QTabWidget,
pg.Qt.loadUiType(uifilename)[0]):
def __init__(self, parent=None):
super().__init__(parent)
self.setupUi(self)
if 'PySide2' in sys.modules:
self.FileNamingWidget = Filename_Folder_Widget()
Probably also works with PyQt5 too. Haven't tested that yet.
Thanks for all your help!
