I let my main program run a loop where all the checking it wants to do
are done and then I run the GUI in a spereate task, so that when I need
to update the GUI I call the Update_GUI below:
task body GUI_task is
begin
Gtk.Main.Set_Locale;
Gdk.Threads.Init;
Gtk.Main.Init;
loop
select
accept Update_GUI do
-- Do the stuff here.......
else
-- If not do all the other things the GUI wants to do...
while Gtk.Main.Events_Pending loop
Dead := Gtk.Main.Main_Iteration;
end loop;
end select;
delay 0.01;
end loop;
exception
when E : others =>
Put_Line ("Exception raised in GUI task:" &
Exception_Information (E));
end GUI_task;
Hope it helps.
