Pyside6 backend raises exception AttributeError: module 'PySide6.QtWidgets' has no attribute 'QAction'

[manuel-koch]

I'm using MacOS 14.1.1 (23B81) on Apple M1 Pro, conda environment

• python 3.11
• pythonocc-core=7.7.2
• PySide6_Essentials=6.6.0

With the following minimal code I get a runtime error

from OCC.Core.BRepPrimAPI import BRepPrimAPI_MakeBox
from OCC.Display.SimpleGui import init_display

def _export_to_png(display):
    # save to other format by changing extension of filename
    display.View.Dump("./capture.png")

def minimal_display_shape_with_screencapture():
    display, start_display, add_menu, add_function_to_menu = init_display()
    box_shape = BRepPrimAPI_MakeBox(50, 30, 10).Shape()
    display.DisplayShape(box_shape, update=True)[0]
    add_menu("screencapture")
    add_function_to_menu("screencapture", functools.partial(_export_to_png,display))
    start_display()

  File "/source/simply_display.py", line 275, in minimal_display_shape_with_screencapture
    add_function_to_menu("screencapture", functools.partial(_export_to_png,display))
  File "/envs/lib/python3.11/site-packages/OCC/Display/SimpleGui.py", line 247, in add_function_to_menu
    win.add_function_to_menu(*args, **kwargs)
  File "/envs/lib/python3.11/site-packages/OCC/Display/SimpleGui.py", line 220, in add_function_to_menu
    _action = QtWidgets.QAction(
              ^^^^^^^^^^^^^^^^^
AttributeError: module 'PySide6.QtWidgets' has no attribute 'QAction'

It will run normally when I don't call add_function_to_menu.
