Handlers and Return_Handlers are inside Handler_Package, and have to be
referenced just like anything else inside a pkg. Just as you say
Gtk.Widget.Gtk_Widget_Record, you should say Handler_Package.Handlers.

But presumably the callbacks are still in your main-program subprogram, which is
not library level, so this won't help you by itself.

Typically I've put everything dealing with GtkAda in the same pkg, except the
call to Gtk.Main.Main. You can look at the Mine Detector game for an example.
