Probably.  I also think the above little code snippet ought to go
in a small function like gtk_flush_draws() or something.  As someone
mentioned already, there are plenty of times when you need to change
a dialog box or display to reflect status as you are doing some
other work.

In similar news, a colleague is having trouble with this:

{
    dialog = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    label = gtk_label_new("Installing packages");
    gtk_container_add(GTK_CONTAINER(dialog), label);
    gtk_widget_show(label);
    gtk_widget_show(dialog);
    while (gtk_events_pending())
        gtk_main_iteration();

    [do lots of other work here]
}

During the "lots of work", the window pops up, but the label is
never shown.  Shouldn't this work?
