Error importing `QtWidgets.QWIDGETSIZE_MAX` with PySide2/6

[niklashenning]

Importing QWIDGETSIZE_MAX from qtpy.QtWidgets works with PyQt5 and PyQt6, but not with PySide6.
I think this might be an issue with PySide6 though, since it's not in PySide6.QtWidgets as the PySide6 documentation suggests.
An easy workaround would be defining QWIDGETSIZE_MAX myself since it's always set to 16777215 but maybe I'm missing something obvious here.

Code:
from qtpy.QtWidgets import QWIDGETSIZE_MAX

Error when using PySide6:
ImportError: cannot import name 'QWIDGETSIZE_MAX' from 'qtpy.QtWidgets' (C:\Users\NH\AppData\Local\Programs\Python\Python311\Lib\site-packages\qtpy\QtWidgets.py)

Hi @niklashenning thank you for pointing the missing constant and sorry for such a late response! At least from my testing, seems like QWIDGETSIZE_MAX is not available for PySide bindings (2 and 6). In any case, we could potencially add/define it manually here around

qtpy/qtpy/QtWidgets.py

Line 180 in 83ecde3

if PYSIDE2 or PYSIDE6:
