QMessageBox crash on macOS 27.0.1
-
Hello,
Since upgrade to macOS 27.0.1 this simple code is crashing with PyQt6 when trying to display the QMessageBox:
import sys from PyQt6.QtWidgets import ( QApplication, QWidget, QPushButton, QMessageBox, QVBoxLayout, ) app = QApplication(sys.argv) window = QWidget() window .setWindowTitle("Sample") button = QPushButton("Display") def display_dialog(): QMessageBox.question( window, "Confirmation", "Continue ?", QMessageBox.StandardButton.Ok | QMessageBox.StandardButton.Cancel, QMessageBox.StandardButton.Cancel, ) button .clicked.connect(display_dialog) layout = QVBoxLayout() layout.addWidget(button) window.setLayout(layout) window .show() sys.exit(app.exec())As workaround this works:
import sys from PyQt6.QtWidgets import ( QApplication, QWidget, QPushButton, QMessageBox, QVBoxLayout, ) app = QApplication(sys.argv) window = QWidget() window.setWindowTitle("Sample") button = QPushButton("Display") def display_dialog(): dialog = QMessageBox(window) dialog.setOption(QMessageBox.Option.DontUseNativeDialog, True) dialog.setWindowTitle("Confirmation") dialog.setText("Continue ?") dialog.setStandardButtons( QMessageBox.StandardButton.Ok | QMessageBox.StandardButton.Cancel ) dialog.exec() button.clicked.connect(display_dialog) layout = QVBoxLayout(window) layout.addWidget(button) window.show() sys.exit(app.exec())So it looks like usage of native dialog box is broken with macOS 27.0.1.
Is this a known issue? If not, can anybody reports this to Qt developers?Thanks
-
Is there maybe some relationship between this and https://forum.qt.io/topic/165172/qfontdialog-on-macos-27-isn-t-modal-anymore ? Maybe there is an issue with native dialog changes?
-
Unlikely, the internal mechanism is different, and I furthermore cannot reproduce any crash with OP's sample.
@Qoissi Please provide more detail - which version of Qt and which version of PyQt? Is the crash due to a Python exception or in native code? Can you provide a stack trace?
-
Hi, sorry it was difficult to get the details because I do not have means to reproduce myself (I'm reporting issues communicated by users of my PyQt6 based program).
Here are the versions used:
PyQt6 6.11.0 PyQt6-Qt6 6.11.2 PyQt6_sip 13.11.0 Python 3.12.12The crash is not due to a Python exception, this is in native code.
As of today the user has not been able to provide a stack trace...But another user, still of macOS 27.0.1 and also using PyQt6 6.11.0 reports this stack when displaying a dialog (not sure this is a QMessageBox).

Hi,
Can you check with the latest version of PySide6 to see if you experience the same crash ?
