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")
