i seem to have to use "Set_Modal"

"procedure Set_Modal
.....
In cunjunction with Gtk.Main.Main, this is the easiest way to show a 
dialog to which the user has to answer before the application can 
continue."

i'm not sure about how to use that
(i prefer do things as clear as possible, to have less chances as 
possible to do mistakes)

what do you think about making a callback procedure, so that it makes 
the window, it calls Gtk.Main.Main, and it finish depending on the 
result given by the user via the window ?

should i integrate Gtk.Main.Main in a procedure where is declared the 
window type, which would make Gtk_New, Show_All, and Gtk.Main.Main at 
the same time ?


an other question, about Gtk.Dialog
http://libre.act-europe.fr/GtkAda/docs/gtkada_rm_63.html#SEC270
i have red that, but it's a little bit confusius for me,
notably because of a lot of functions which make stuff, instead of 
being procedures

so, when have i to use a Gtk.Dialog rather than a Gtk.Window ?
