  It sounds like you're trying to do a ruler view. I think DrawKit  
does rulers, so I'd be surprised if that wasn't what Graham is using.  
Can't you just subclass whatever ruler Graham uses and add your stuff?  
Or, come to think of it, I think you can actually have several rulers  
on a view, so you could probably create your own based on Graham's code.
