I made a little complement :

/* Next */
GtkCTreeNode *gtdk_ctree_next (GtkCTreeNode *node)
{
  GtkCTreeNode *node_parent;

  /* Go ! */
  if (GTK_CTREE_ROW (node)->children)
    return (GTK_CTREE_ROW (node)->children);
  if (GTK_CTREE_ROW (node)->sibling)
    return (GTK_CTREE_ROW (node)->sibling);
  do
    {
      node_parent = GTK_CTREE_ROW (node)->parent;
      if (!node_parent)
	node = NULL;
      else
	if (GTK_CTREE_ROW (node_parent)->sibling == NULL)
	  node = node_parent;
	else
	  node = GTK_CTREE_ROW (node_parent)->sibling;
    }
  while ((node == node_parent) && (node));
  return node;
}
