Call a function when user closes app ( pyQt5 )

Question

I want to have my app save data before closing itself. I can have the user use the quit button (I made myself) that is connected to a function. But I don't know how to call the function when the user closes the app native close button.

Is there a way to call a function when the user uses the close button as mentioned in the screenshot above? Thank you for your time in advance. :)

Most common way would be:

class MainWidget(QtWidgets.QWidget):

    #...

    def closeEvent(self, event):
        print "closing PyQtTest"
        self.SaveSettings()
        # report_session()

Or atexit module of the standard Python.

It gives me this error: "AttributeError: module 'PyQt5.QtGui' has no attribute 'QWidget'". Even though I have imported: "from PyQt5 import QtCore, QtGui, QtWidgets". – Ali Jul 07 '21 at 16:25

It still did not work. I close the app and the print function doesn't get executed. – Ali Jul 07 '21 at 16:40
@AliHaiderSultani are you by any chance editing a pyuic generated file? – musicamante Jul 07 '21 at 16:50
