Dialog-item-actions take a single parameter: the dialog item
itself. However, menu-item-actions don't take any parameters. Why is
that? I would like to refer to a menu-item from within its
menu-item-action. Is there an easy way to do that?
Here is a plug for my menu-enhancements package. The package
supports window-menu-items that have the functionality that
you want, allowing you to say
:menu-item-action #'(lambda (item) item ....))
where item is bound to the menu-item
the containing-view function can extract the view that
contains the menu-item.
You could also consider using the following code in
the standard system:
(setq fred (make-instance 'menu-item :menu-item-title "Fred"))
(setf (menu-item-action-function fred)
(print (menu-item-title fred))))
The real problem with Macintosh menus is that they understand
a parameter free environment (menu-item) and a window environment
(window-menu-item) but they don't understand views, dialog items etc.
This forces you to go through a convoluted sequence when you want
to operate on a selected item.
