How can I find out when a NSTabViewItem has been changed, i.e. a user has changed the view of an NSTabView?
Ideally I want to generate a notification but any solution would be welcome.

My original answer suggested to observe
selectedTabViewItemofNSTabView, but that doesn’t seem to work (on testing I can only get it to observeNSKeyValueObservingOptionInitial).A probably smarter solution is to use a delegate. Implement
tabView:didSelectTabViewItem:in the relevant controller.Docs here.
