How to hide/disable close button or at least catch/override built-in quit() function? (Kivy)

I need to do some actions before quit (save settings, etc.), I do it with Button widgets, but if I press on close button of the window, it just closes. Maybe I should handle App's on_close() event somehow? Then I don't know how to send data from Layout to App. For now I have smth like:

def quit_game(self):
        # Saving different data.
        ...
        quit()

What should I do?

Yes, you should handle the on_stop method on your App class by implementing the appropriate method.

Example:

class MyApp(App):
    ...
    def on_stop(self):
        # do what you need to here
        value_to_save = self.root.subwidget.value
        # self.root is your root widget - either the 
        # widget you return from App.build() or
        # the root widget in your app kv file

Keep in mind, also, that if you plan to develop for Android you will need to implement on_pause as well. After an Android app is paused, it can be killed without warning by the OS and your on_stop method will not be called.
