| NSMenuValidation |
Mac OS X 10.0 |
This informal protocol declares the single method
validateMenuItem:, which is implemented by classes
of the a
menu's target object. The class implements this
method to return a BOOL specifying whether the
menu item should be enabled or disabled. Whenever a menu is
displayed, each menu item will send a
validateMenuItem: message to its target (if the
target responds), which then responds with YES or
NO depending on whether or not the menu item
should be enabled.
