Both work on immediate children. You must call them recursively,
something like that:

void
action(GtkWidget *widget)
{
  /* Do something */
}

void
callback(GtkWidget *widget)
{
  action(widget);
  if (GTK_IS_CONTAINER(widget))
      gtk_container_foreach(GTK_CONTAINER(widget),
                            callback, NULL);

}

gtk_container_foreach() is the way: the forall() version
traverses also internal stuff I think you don't care about.
