Current GtkProgressBar usage

[Nikolaj Thygesen <mailinglist diamondbox dk>]

Hi list,

   I have used GtkProgressBar's for a while, and back when I started 
some years ago, it was necessary to call something like:
       while(g_main_context_iteration(0, FALSE));

to have the UI updated. These days it seems like this is no longer 
necessary - is that correct? I'm doing it from a thread other than the 
"gtk_main"-thread - I'm aware of and handling the usual locking details 
of gtk.
   On a related note, it seems impossible to do the aforementioned 
iteration line from "other" threads even when handling locking - is that 
correct? I've tried both holding the lock meanwhile and releasing it for 
this single line. Perhaps it's messing up the initial MainLoop I don't know.
   Best regards - Nikolaj
