No. MenuExtras are "plugins" to the Apple SystemUIServer, which itself is managing these special plugins. NSMenuExtra is a private implementation, a subclass of NSStatusItem, but the private interface was reverse engineered in the 10.0-10.1 era. Apple blocked the use of the non-Apple provided MenuExtras in 10.2 by limiting it to only Apple instances, but MenuCracker did re-enable it. There are still several non-Apple MenuExtras today, mostly because of the flexibility they bring (for example MenuExtras can be repositioned in the menu bar, or removed, with the command key, what StatusItems cannot). If you open a StatuItem, you can navigate in its menu with the keyboard (you stay within this process alone), but not navigate to an other process (so, not to SystemUIServer). However all MenuExtras are working "within" the SystemUIServer process, so accessbility works within it, and you can navigate from one MenuExtra item to the next. Spotlight is also managed by SystemUIServer (but you can't navigate to it - I don't know why), but not the Notification manager. -- Stephane _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
