Not Evaluated The following snippet can be used to show the unexpected behavior:
import sys
from PySide6 import QtCore, QtWidgets
from shiboken6 import Shiboken
class MyObject(QtCore.QObject):
pass
my_object = MyObject()
app = QtWidgets.QApplication(sys.argv)
QtCore.QTimer.singleShot(500, app.quit)
app.exec()
print('Shiboken.isValid:', Shiboken.isValid(my_object))
Shiboken.delete(app)
print('Shiboken.isValid:', Shiboken.isValid(my_object))
Output:
>>> Shiboken.isValid: True >>> Shiboken.isValid: False <--- Unexpected
my_object is deleted after the call to Shiboken.delete(app); if any of its methods is accessed, the following exception is raised:
RuntimeError: Internal C++ object (MyObject) already deleted.
The issue can be seen with other, more involved Qt types, such as QtCore.QSettings.
Why would Shiboken.delete() end up deleting other, unrelated objects? This behavior cannot be reproduced with PySide 5.15.2.
