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!
Peter.
