Window signal and slots not working

[pvlopez]

I'm having a problem with the closeEvent() function override in a class which is not triggering.
This is the code I have in the main.py file:

from mainwindow import *

if __name__ == '__main__':
    app = QApplication()
    mainwindow = QMainWindow()
    window = Ui_MainWindow()
    window.setupUi(mainwindow)
    mainwindow.show()
    app.exec_()

And then in another file named mainwindow.py I have:

class Ui_MainWindow(QMainWindow):
    def setupUi(self, MainWindow):
      .......
    def retranslateUi(self, MainWindow):
         ........
    def closeEvent(self,event):
        print("Testing")

But when I close the window the closeEvent() function never runs.
I'm missing something or doing it wrong but I can't figure out what it is.
Please help.

Please don't multi-post the question, do you want people to waste their time answering in two places while others are answering too?
