Ok Dmitry. I'll convert my project with this method and watch,what happens =
with it. But whether it not a waste of time to do GUI application manually?

p.s. And, BTW, i couldn't install GPS installer today, GTKADA contributions=
 and other components on GNAT 2016 with compiled and built gps_installer.ex=
e, so i've put folder "gtkada_contributions" with my project and use that f=
iles this way: "with Gtk.Main.Router;" etc. What can I do to install it pro=
perly? or GNAT 2016 doesn't supported?
Thanks.
