Re: [Rubycocoa-talk] small prob with a menu item

[Jonathan P. <jp...@dc...>]

Here's the relevant bit from the documentation. Note that automatic =20
enabling is on by default.





Enabling Menu Items

By default, every time a user event occurs, NSMenu automatically =20
enables and disables each visible menu item. You can also force a =20
menu to update using NSMenu=92s update method.

There are two ways to enable menus:

=93Automatic Menu Enabling=94 NSMenu updates every menu item whenever a =20=

user event occurs. A menu item is enabled if NSMenu can find an =20
appropriate object that responds to the menu item=92s action. If you =20
want a menu item to remain disabled even though an object responds to =20=

the menu item=92s action, define a validateMenuItem: method for that =20
object.
=93Manual Menu Enabling=94 You use setEnabled: to enable or disable =
every =20
menu item individually.
To choose a system, use NSMenu=92s setAutoenablesItems: with an =20
argument of YES (for automatic menu enabling) or NO (for manual menu =20
enabling). Automatic menu enabling is on by default.
