-It is also possible to add menus and sub-menu's as toolbar items, as well as you can implement tear offs. However, notice that menu items emit a different signal((*'activate'*))than tool-menu items((*'clicked'*))when clicked. Following is expanded example program including the menu toolbar item with the language sub-menu, you already saw in previous section. In addition to the toolbar menu item, we also included two Gtk::ToolButton objects with user supplied icon image. The image can be passed to the Gtk::ToolButton constructor as an((*image file*))or as a((*pixbuf.*))Our 'toolbar-item-menu.rb' example shows both of these two ways of supplying image objects to the toolbar item constructor.
