that is: until your loop returns control to the (gtk) main loop; one
(easy) way to do what you want is to allow the main loop to accomplish
its tasks (among which the refreshing of current progress bar settings)
is the following:
for (i = 0; i < iterations; i ++)
{
<do "w1">
fraction = (gdouble)(i + 1) / iterations;
gtk_progress_bar_set_fraction (GTK_PROGRESS_BAR (widget), fraction);
while (gtk_events_pending ())
{
gtk_main_iteration ();
}
}
