PyQT5 Exit Confirmation

This is a small post explaining how you can add an exit confirmation to your PyQT5 code.

Simply add this code to your MainWindow class:

Remember to:

[PyQT5] from PyQt5.QtWidgets import QMessageBox

[PySide2] from PySide2.QtWidgets import QMessageBox

def closeEvent(self, event):

      quit_msg = "Are you sure you want to exit the program?"
      reply = QMessageBox.question(self, 'Message',
                     quit_msg, QMessageBox.Yes, QMessageBox.No)

      if reply == QMessageBox.Yes:
         event.accept()
      else:
         event.ignore()
