[gtkada] A list of rows of widgets

[Arnaud Charlet]

With GtkAda 1.2, the only solution is to use Gtk.Extra.Sheet

With Gtk+/GtkAda 2.0, there is a new widget GtkTreeView that allows to do
what you want, even if it might be a little bit extra work.

With Gtk+ 2.2, there will be a sheet widget (an extension of GtkTreeView)
that follows the MVC design pattern.
