 *
 * Children are added using attach(). They can span multiple
 * rows or columns. It is also possible to add a child next to an
 * existing child, using attach_next_to().
 *
 * Grid can be used like a Box by just using Gtk::Container::add(),
 * which will place children next to each other in the direction determined
 * by the orientation property.
