Hello,
if I use g_idle_add, then when the function from g_idle_add is
executed, it blocks the 'update_pbar' function.
So I probably must make it with threads but by now I think it's to
early for me to work with threads. It's easier if I add the
progressbar into the main window, and update it with:
while (gtk_events_pending())
gtk_main_iteration();
Later I would probably try it with threads.
Thanks for the help.
