So why doesn't this work as I expect?
Template, BaseClass = pg.Qt.loadUiType(uifilename.as_posix())
self.FileNamingWidget = Template()
widget = BaseClass()
self.FileNamingWidget.setupUi(widget)
When I try to add self.FileNamingWidget to my layout, I get an error.
self.ui.PluginLayout.addWidget(self.FileNamingWidget)
Traceback (most recent call last):

int, int, int, PySide2.QtCore.Qt.Alignment = Default(Qt.Alignment))
PySide2.QtWidgets.QGridLayout.addWidget(PySide2.QtWidgets.QWidget)
self.FilenamingWidget is a
<Ui_Filename_Folder_Widget object at 0x000001DAF81762C8>
but if I use loader.load(), it is
loader.load(uifilename.as_posix())
<PySide2.QtWidgets.QTabWidget(0x1dafaf6c200, name="Filename_Folder_Widget")
at 0x000001DAFC3179C8>
and I can add this to my Layout. I get the same error under PyQt5 with
loadUiType, but uic.loadUi() works fine.
self.FileNamingWidget
Out[4]: <Ui_Filename_Folder_Widget at 0x22a97fa9c88>
uic.loadUi(uifilename.as_posix())
Out[3]: <PyQt5.QtWidgets.QTabWidget at 0x22a999fd9d8>
