public bool register_session { get; set; }
Warning: register_session is deprecated since 4.22.
Set this property to true to register with the session manager.
This property is ignored. GTK always registers with the session manager
This will make GTK track the session state (such as the [property@Gtk.Application:screensaver-active] property).
