It has methods to do what you want. Yes, that looks like it will do what I need. Hopefully the code will be fast enough to just use - (void)menuNeedsUpdate:(NSMenu *)menu otherwise I'll have to do a bit more work to get - (NSInteger)numberOfItemsInMenu:(NSMenu *)menu - (BOOL)menu:(NSMenu *)menu updateItem:(NSMenuItem *)item atIndex:(NSInteger)index shouldCancel:(BOOL)shouldCancel working. And I did know about NSPopUpButtonWillPopUpNotification, and indeed that was what I was using, but unfortunately it was taking about a minute to populate the menu, and therein lies the problem. The menu is only about three or four levels deep in the normal case, and a menu selection is definitely the right UI for this use case, not a browser or some other mechanism. About the only other good UI would be a big custom UI designed specifically for this use, and that's more work than I want for little or no gain in usability. Thanks for the comments!

If the button's menu has dynamic content, how are you going to achieve it without 'dipping your fingers' into its menu? That's why it has a public -menu method, which you'd have to use from your notification handler anyway. The delegate approach is more direct and the supported way to do this. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Dynamically populate a popup menu
Yes, but using the notification does not solve the OP problem that is: I have to much submenu and item to compute then at one time. Not to mention the fact that he asked for a popup menu, but he does not talk about a popup button. That said, having more than one level of submenu is again Interface Guidelines (see "Hierarchical Menus (Submenus)" section in Interface Guidelines): "Because submenus add complexity to the interface and are physically more difficult to use, you should use them only when you have more menus than fit in the menu bar or for closely related commands. Use only one level of submenus. If a submenu contains more than five items, consider giving it its own menu." Using a Menu to browser the disk is maybe not the way to go.

While NSMenuDelegate isn't wrong per se, I still prefer to use the NSPopUpButton's notification myself.

Re: Dynamically populate a popup menu
See NSMenuDelegate protocol. There is some method to dynamically populate the menu.

Dynamically populate a popup menu
Is there any way to dynamically populate a popup menu on the fly (as it is exposed)? For example, a popup menu that displayed the harddisk hierarchy would need this sort of thing - you wouldn't want the entire thing populated as soon as you click the popup menu, it would take forever and the user would never see most of it. Can it be done by subclassing NSMenuItem etc? The only alternative I can see would be some sort of custom control based on NSBrowser, but that would be a lot uglier for this sort of selection.
