/** Create buttons bound to a URL.
 *
 * A Gtk::LinkButton is a Gtk::Button with a hyperlink, similar to the one
 * used by web browsers, which triggers an action when clicked. It is useful
 * to show quick links to resources.
 *
 * The URI bound to a Gtk::LinkButton can be set specifically using set_uri(),
 * and retrieved using get_uri().
 * By default, Gtk::LinkButton calls gtk_show_uri() when the button is clicked.
 * This behaviour can be overridden by connecting to the activate_link signal and
 * returning true from the signal handler.
 *
 * The LinkButton widget looks like this:
 * @image html linkbutton1.png
 *
 * @newin{2,10}
