I mentioned NSDocument app simce that is where I am and the content is
contained in a scroll view.
I wan to send to my model code that the user scrolled the view and I
want to know by how much.
So, I thought I would implement trackKnob but I don't know how ....

Is there an 'easy' way to get NSScroller events in an NSDocument

I would like to know where the knob is.
The knob's position is just the -floatValue (or -intValue) of the
scroller control.
What are you trying to do? NSDocument is not part of the 'view'
layer of MVC so it's unclear how the two are related. If you want to
send an action in response to a scroller just hook it up to an
action method. However, scrollers are not a good control to use when
you really mean e.g. a slider.
