Now I see, the target/action is specific for NSControl and not for NSView, I haven't noticed it before. > I suspect that this might be a blind alley though - what are you trying to > actually do? Likely that NSNotificaiton could be more suitable. Notifications is another point of confusion for me. I would assume that notifications should be used when multiple observers can be connected to an "event" exposed by an object, in contrast to a simple "delegate" outlet, which can only have one connected object. Am I correct? What I am actually trying to do is to build a custom editor view that would notify it's parent window when the state of the view changes, e.g. due to user actions. I think delegate is the right choice, correct?
