I need to know when a text view becomes First Responder. I thought the notification NSTextDidBeginEditingNotification would do it, but that’s only sent when the user starts typing in the text view, which is too late for my purposes.
Is there another notification that I could use that signals a view has become FR? I couldn’t see anything either specific to NSTextView (or NSText) or views/responders in general. I’d prefer not to have to use a text view subclass if possible, though if that’s the only way so be it.
