Handling quit requests¶
Most platforms have the option to request the application to quit. On desktops, this is usually done with the “x” icon on the window title bar. On Android, the back button is used to quit when on the main screen (and to go back otherwise).

has a special
MainLoop.NOTIFICATION_WM_QUIT_REQUEST notification that is
sent to all nodes when quitting is requested.
MainLoop.NOTIFICATION_WM_GO_BACK_REQUEST is sent instead.
Pressing the Back button will exit the application if
Application > Config > Quit On Go Back is checked in the Project Settings
(which is the default).
MainLoop.NOTIFICATION_WM_GO_BACK_REQUEST isn’t supported on iOS, as
