LispWorks CAPI User Guide > 8 Creating Menus


8.3 Creating individual menu items

The menu-item class lets you create individual menu items. These items can be passed to menu-components or menus via the :items keyword. Using this class, you can assign different callbacks to different menu items.

(setq test (make-instance 'menu-item
                            :title "Test"
                            :callback 'test-callback))
(setq hello (make-instance 'menu-item
                            :title "Hello"
                            :callback 'hello))
(setq group (make-instance 'menu-component
                            :items (list test hello)))
(contain group)

Remember that each instance of a menu item must not be used in more than one place at a time.
