Signals during mainwindow.close()

Question

I have a mainwindow and from that I call another window, I want the a a slot to get executed when the second window is closed. Is there any way to do that?

new_window = secondWindow()
new_window.show()
new_window.closed.connect(self.another function)

Is there any signal defined like this, or is there some other way to do that without closing the main window?

Answer 1

The solution is to create a custom signal, and emit this signal in the closeEvent method:

class secondWindow(WidgetClass):
    closed = pyqtSignal()
    [...]

    def closeEvent(self, event):
        self.closed.emit()
        WidgetClass.closeEvent(self, event)
