Gtk::MenuBar is a widget that organizes multiple pop-up menus into a horizontal or vertical row. Each root element is a Gtk::MenuItem that pops down into a submenu. An instance of Gtk::MenuBar is usually displayed along the top of the main application window to provide access to functionality provided by the application.

A new menu bar widget is created with Gtk::MenuBar.new. This creates an empty menu shell into which you add content. After you have created a menu bar you can set a pack direction with Gtk::MenuBar#pack_direction=(pack_dir), where pack_dir is one of the constants defined in Gtk::MenuBar::PackDirection. By default pack direction is left to right (Gtk::MenuBar::PACK_DIRECTION_LTR). Gtk::MenuBar class provides also child_pack_direction=(pack_dir) instance method, which sets how widgets should be packed inside the children of a menubar.
