For gtk :
-------------------------------------------------
int idle_func_id ;
gint idle_function(gpointer data) ;
/* must return TRUE to continue ( FALSE disable idle function ) */
idle_func_id = gtk_idle_add(idle_function,data) ;
/* and */
gtk_idle_remove(idle_func_id) ;
-------------------------------------------------
I use that to display real-time video acquisition.
(precise time but large period -> enough time to display between 2
acquisitions)
