How to handle KeyboardInterrupt? Ctrl+C IOT instruction (core dumped).

[AI-Maria]

I want to shutdown when Ctrl+C is pressed.

from PyQt5.QtWidgets import QMainWindow, QSplitter, QPushButton
from PyQt5.QtCore import Qt
from qasync import QEventLoop, QApplication, asyncClose, asyncSlot
import sys
import asyncio

class MainWindow(QMainWindow):
    def __init__(self, app):
        self.app = app
        super().__init__()
        self.setWindowTitle("MainWindow")
        self.setGeometry(100, 100, 800, 600)
        splitter = QSplitter(Qt.Horizontal)
        self.setCentralWidget(splitter)
        send_button = QPushButton('button')
        splitter.addWidget(send_button)


    @asyncClose
    async def closeEvent(self, event):
        pass

    @asyncSlot()
    async def onMyEvent(self):
        pass

def main():
    app = QApplication(sys.argv)

    event_loop = QEventLoop(app)
    asyncio.set_event_loop(event_loop)

    app_close_event = asyncio.Event()
    app.aboutToQuit.connect(app_close_event.set)

    main_window = MainWindow(app)
    main_window.show()

    with event_loop:
        event_loop.run_until_complete(app_close_event.wait())

main()

python test.py
Press Ctrl+C and close button.

I do not get the segfault on PySide6 and latest qasync:

def main():
    app = QApplication(sys.argv)
    app_close_event = asyncio.Event()
    app.aboutToQuit.connect(app_close_event.set)
    main_window = MainWindow(app)
    main_window.show()

    asyncio.run(app_close_event.wait(), loop_factory=QEventLoop)


try:
    main()
except KeyboardInterrupt:
    print("KeyboardInterrupt")
