This function is only useful on the X11/freedesktop.org platform.
It returns a window ID for the widget in the underlying
status icon implementation. This is useful for the Galago
notification service, which can send a window ID in the protocol
in order for the server to position notification windows
pointing to a status icon reliably.
This function is not intended for other use cases which are
more likely to be met by one of the non-X11 specific methods, such
as gtk_status_icon_position_menu().
Since 2.14
