[gtkada] window refreh in GtkAda

[Manuel Op de Coul]

Are you sure you want to use an entry and not a label for this?

In any case you need to add an idle handler to your
task to process any gtk events in the event queue.
Something like this

   function Idle return Boolean is
      Dummy : Boolean;
   begin
      while Gtk.Main.Events_Pending loop
         Dummy := Gtk.Main.Main_Iteration;
      end loop;
      return True;
   end Idle;

   task body ...
      Id : Gtk.Main.Idle_Handler_Id;
   begin
      ...
      Id := Gtk.Main.Idle_Add(Cb => Idle'Access);


And be sure to carefully read the GtkAda User Guide about
tasking and GtkAda!
