BUG: Incompatible with PySide6 6.7.0

[larsoner]

6.7.0 just released today, using this code:

from qtpy import API
from qtpy.QtWidgets import (
    QFileDialog,
    QApplication,
    QWidget,
)
assert API == "pyside6", f"{API=}"

QApplication([])


class A(QFileDialog):
    def __init__(self):
        super().__init__(None)

print(isinstance(QFileDialog(), QWidget))
print(isinstance(A(), QWidget))

on 6.6.3.1 I get the expected:

True
True

but on 6.7.0 I get:

False
False

and if I change the import at the top to be from PySide6.QtWidgets things are again fine, so something is broken with qtpy specifically.

[larsoner]

Okay this is some very weird upstream bug, this code fails on 6.7.0:

from PySide6.QtGui import QActionGroup
from PySide6.QtWidgets import *

QApplication([])
assert isinstance(QFileDialog(), QWidget)

if you comment out the QActionGroup import or move it after the star import things are fine.

So, do you think this is an issue with qtpy or PySide6?

[larsoner]

PySide6, I opened https://bugreports.qt.io/browse/PYSIDE-2674 upstream. I tried messing with the import order in qtpy to work around the issue but couldn't, so I'll close!
