How to change event behavior minimization in PyQt or PySide?

I am developing a Qt application and changing the closing behavior using a closeEventvirtual function as follows:

class MainWindow(QMainWindow):
    def closeEvent(self, event):
            event.ignore()
            self.hide()
            self.trayicon.showMessage('Running', 'Running in the background.')

This works as expected. If I delete event.ignore(), the application will stop working, everything will be fine.

I also want to control the minimize event, so when the user clicks the minimize button in the title bar, I want to move the window, not minimize it. I cannot use the hideEventvirtual function because the event will still be sent to the window, so this code:

def hideEvent(self, event):
    event.ignore()
    self.move(0,0)

moves the window to the upper left and then minimizes it. event.ignore()not valid here, so I tried using QtCore.QObject.eventas follows:

def event(self, event):
    if event.type() == QEvent.WindowStateChange:
        if self.isMinimized():
            event.ignore()
            self.move(0,0)
            return True
    return False

, . ? ?
