I'd be happy to post the solution if I find it, however my intent was
rather to *get* than *provide* help :-)

I thought a solution could be to return "True" from the callback. I
therefore replaced the instantiation of Gtk.Handlers.Callbacks with
Gtk.Handlers.Return_Callback (on type Boolean of course).
Alas! I got a message that return types were not supported with GtkAda!
(and BTW, I don't know how to specify that the callback returns boolean
from Glade).

Did I miss something?
