Description

The simplest way to give a title to a titled-menu-object is to just supply a title string, and this will then appear as the title of the object. Alternatively, a title-function can be provided which will be called with the object when the menu is about to appear and which should return the title to use.

To specify a mnemonic in the title returned by title-function , make title-function return the mnemonic as a second value. This is interpreted in the same way as the mnemonic initarg for menu.

Examples

(capi:contain (make-instance 'capi:menu-item

                             :title "Press Me"))

(capi:contain (make-instance

               'capi:menu-item

               :title-function #'(lambda (item)

                                   (princ-to-string

                                    (random 5)))))
