The "C" sample code you may want to use looks like:

static re_curse_container(GtkContainer *container, gboolean 
include_internals);

static void pop_on_child(GtkWidget *widget, gboolean include_internals)
{
   if (GTK_IS_CONTAINER(widget)) {
   /* you've got another container */
       re_curse_container(GTK_CONTAINER(widget), include_internals);
   }
   else {
   /* this's a non-container child widget */
   }
}

static void re_curse_container(GtkContainer *container, gboolean 
include_internals)
{
   if (!include_internals)
           gtk_container_foreach(container, pop_on_child, 
include_internals);
   else gtk_container_forall(container, pop_on_child, include_internals);
}
