Re: Problem to open a new window using libglade

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())

Later I would probably try it with threads.

Thanks for the help.

you either need another scheduled function (prolly g_idle_add) or start
a separate thread when entering your callback and join it before ending.

You prolly want to avoid multi-threading for such a rather limited

Also, I've noted a flaw in my pseudo-code around setting dialog to NULL
which does not change the pointer that has already been passed to
update_pbar ... a static global would prolly do here or smth. similar.
