What kind of changes? In general, adding and removing menu items is discouraged in Mac apps. Disabling menu items that don't apply to the current document and/or selection is the preferred approach, and for that you don't need a pointer to the menu. The current document is in the responder chain, so if it doesn't respond to a menu item's action message, that menu item will be disabled automatically. For more detailed control, for example to disable a menu item based on the current selection in a document, one can write a -validateMenuItem: method to decide whether the given menu item should be enabled or not. I'm not trying to give you the "HIG lecture," I'm just saying - depending on what you want to do, there might be an easier way to do it that doesn't actually need a pointer to the main menu. On the other hand, there are certainly reasons to alter the main menu in other ways that *do* require such a pointer. So, if you do need it, there's NSApplications's mainMenu method, which you can call using the NSApp global, as in: NSMenu *menu = [NSApp mainMenu]; sherm-- -- Cocoa programming in Perl: http://camelbones.sourceforge.net _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
