I'd like a viewController to be notified whenever an arrayController adds a new object. Here's why:
I have an NSTextField in a view that gets added in an NSCollectionView. There's also an array controller and when I fire the "add:" selector the new view shows up in the collection. The view that gets added has an NSTextField in it and I want the cursor to be in there and ready so the user can just start typing. So I guess this is a two-part question:
1) how do I get notified if a new object is added?
2) how do I make the NSTextField in the view that just was added ready and waiting to be typed in?
Thanks!_______________________________________________
