[PySide] QtDesigner ???

[David Ching]

Hi Paolo,

I could not reproduce.   Either:

[pyDBManager.py]
#from Ui.DBManagerMainWindowGood import Ui_DBManagerMainWindow
from Ui.DBManagerMainWindowBad import Ui_DBManagerMainWindow

Or:
[pyDBManager.py]
from Ui.DBManagerMainWindowGood import Ui_DBManagerMainWindow
#from Ui.DBManagerMainWindowBad import Ui_DBManagerMainWindow

Ran without error.  The first added the Label and LineEdit as expected.

I ran your batch file after modifying it to work on my system (removed
hard-coded paths, etc.)  So I re-ran pyside6-uic and pyside6-rcc and ensured
the generated files were the same as yours.  They were, except for the
tooling version in the comments.  Mine is slightly older: 

My system:
    * Windows 10
    * Python 3.9.6 (from https://python.org)
    * PySide6 6.2.3

In short, the (essentially) exact .py code works flawlessly here.

Let me know if I can help more,
David
