The one thing I'm not really clear on is what the Cocoa equivalent

really a direct equivalent in Cocoa and that the best way to do
things would be to have a custom view inheriting from NSControl.
Would that be right?
Jo, do you mean a dialog 'user item'?
These items did nothing except define a rectangular region of the
dialog that you could customise in some unspecified way. The cocoa
equivalent would be NSView, though it gives you far more than just a
frame and then leaves the rest to you.
You could certainly subclass NSControl if you wanted a custom control
(NSControl subclasses NSView) but NSView is more flexible in many
ways, as all more general objects tend to be.
