First principle is that when you make GUI with GtkAda (GTK+) you should
not do it the way Delphi projects do. That is put buttons etc in fixed
positions. GTK+ uses horisontal and vertical boxes to pack buttons
etc... so that when you scale your application the layout looks good.

I recommend that you look at these links, even though the examples are
in C it is easy to translate into Ada 95 using GtkAda:

GTK+ / Gnome Application Development by Havoc Pennington :

on packing widgets:

   http://developer.gnome.org/doc/GGAD/cha-gtk.html

the whole book can be found here:

   http://developer.gnome.org/doc/GGAD/

GTK+ Tutorial by Tony Gale, Ian Main

on packing widgets:

   http://www.gtk.org/tutorial/gtk_tut-4.html

the whole tutorial

   http://www.gtk.org/tutorial/

And of course the GtkAda documentation.

I dunno, I use Linux as I find that Windows suck.

And how many $ do you have to pay up for the public version of  GNAT +
GtkAda + Glade compared to MSVC++? :-)

The Linux version works nicely at least and I'm very impressed with the
work put in by the GtkAda developers.
