Hi Nick- There is some composition of views needed to make this work. Within GCDrawKit, find the GCZoomView class… make your custom view a subview of this (to adopt all of its zoomy goodness). Then, make your custom drawing view the documentView of an NSScrollView.
You'll now need to wire up some controls in the UI (i.e. some menu items or buttons) to call the various zooming methods that your view has now inherited from GCZoomView. Once you're wired up correctly, everything will "just work" - the scroll view will respond to the size changes of your document, and your drawing will now scale up and down per the user's use of the controls you've provided. It is a really nice bit of code (thanks Graham!)
