QT4, QT5 and GTK+2 components handle the "X11 session management protocol".
To handle it with Gambas, you just have to define the
Application.Restart property with a string array that defines the
command that will be run to automatically restart your application the
next time the desktop starts again.
When the desktop shutdowns, it is supposed to gracefully close the
windows of your application, so that you can cancel the shutdown. If you
do nothing, your application will be closed gracefully. It will be
killed only if it does not answer to the window close events.
GTK+3 component does not support that protocol (hey, it's a modern
toolkit!), and I don't think there is the equivalent on Wayland, but I
may be wrong. I need more information about that.
