So what is the purpose of the submenu items if they don't have an action? Not that it matters much. The only way to display the submenu is to display the menu item (well, the menu item's menu), so the menu item validation is going to be called first. You can use validation of the menu item to trigger updating of or contextualizing the submenu. That's the ordinary way, too. I forgot to say in my earlier response: You probably don't (in general) want to make a window controller the delegate of a *menu*, because this means the window controller is going to need knowledge of the structure of the menus themselves, and that's not desirable -- if you moved an item to a different menu, you'd likely have to change the window controller too. The 'validateUserInterfaceItem:' mechanism divorces the menu item behavior from the menu structure. It also (potentially) integrates validation across menu-bar menus, context menus, popup button menus and toolbar items. It's "really" the action being validated, not the UI representation of the action, if you want to think of it that way. The example you raised, though, where a submenu changes in response to (say) the document state *is* an example of the window controller needing knowledge of the menu structure (part of it, anyway). _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
