I'm just learning Python and the Kivy framework. I can't seem to find any specific complete examples of being able to gracefully exit a Kivy app using code linked to a button.

I have found Kivy code snippets like this

Button:
    id:btnExit
    text:"Exit"
    on_press: app.Exit()

But not any matching code that implements the app.Exit() call. Everything I've tried stops code execution but doesn't clean up the program window.

I've read that Android and iOS style guides state that a program is not to programmatically exit and let the OS handle it but I am developing fullscreen borderless Desktop app and need a way to exit the program with a button press.

Try using App.get_running_app().stop(). For more details, read the Kivy documentation article for the function.

If you want to plug your own way of doing settings, without the Kivy panel or close/config change events, this is the method you want to overload.

Comments
  • That's one of the methods I tried but it doesn't clean up the window. The code stops executing but the window is not destroyed.
  • See this discussion groups.google.com/forum/#!topic/kivy-users/saWDLoYCSZ4
  • Thanks, your solution works when executing it from the python shell. I was having the same issue with the IDE not allowing the window to close.
  • To use above code in kv language file, you must import App like this: #:import App kivy.app.App
  • I prefer quit() since it ends all pythonic codes no matter the framework. In kivy it'll be on_press: quit()
  • in kivy app quit() on_press : crash App (*in new android toolchain)
