8.6 Mnemonics in menus

On Microsoft Windows and GTK+ you can control the mnemonics in menu titles and menu items using the initargs :mnemonic, :mnemonic-title (and if necessary :mnemonic-escape).

This example illustrates the various ways you can specify the mnemonics in a menu:

(contain 

 (make-instance

  'menu 

  :mnemonic-title "M&nemonics"

  :items 

  (list

   (make-instance 'menu-item

                  :data "Menu Item 1"

                  :mnemonic #\1)

   (make-instance 'menu-item

                  :data "Menu Item 2"

                  :mnemonic 10)

   (make-instance 'menu-item

                  :mnemonic-title "Menu Item &3")

   (make-instance 'menu-item

                  :mnemonic-title "Menu Item !4"

                  :mnemonic-escape #\!)

   (make-instance 'menu-item

                  :data "Menu Item 5"

                  :mnemonic :default)

   (make-instance 'menu-item

                  :data "Menu Item 6"

                  :mnemonic :none))))

On Microsoft Windows you may need to press Alt to make the underlines appear.

This example shows two ways to specify menu title mnemonics within the :menus option of a define-interface form. The first way, using :mnemonic, is the most natural:

(capi:define-interface menu-bar-mnemonics ()

  ()

  (:panes (pane1 capi:text-input-pane

                 :visible-min-width 200))

  (:layouts (main-layout 

             capi:column-layout '(pane1)))

  (:menus

   (menu1 "Menu One"

          (("Foo"))

          :mnemonic #\O)

   (menu2 nil

          (("Bar"))

          :mnemonic-title "Menu &Two"))

  (:menu-bar menu1 menu2))

(capi:display (make-instance 'menu-bar-mnemonics))
