According to the code you posted On_Window_Destroy is a signal handler
connected to the "destroy" event. The intended use of such handler in Gtk
is to free all resources associated with the widget which are not managed
by Gtk.

In Gtk you shall never call any handlers explicitly.

Destroy emits the "destroy" event, which in turn notifies all handlers of
the signal, all reference holders release the reference which then lead to
deallocation of the widget.
