Drawing with NSCell or NSView and reducing -drawRect: clutter?

[Daniel J Farrell]

Hello,

(please see below for the reasoning behind these questions)

1) Can I tell an NSCell to draw paths?

2) Is it a good idea to reduce clutter in -drawRect: by using simple  
helper objects to draw? I would find this aesthetically more pleasing  
compared to just adding methods to the NSView subclass. As for the  
former, I can have a one-to-one relationship between custom drawing  
objects and model objects (see below for more details about this).  
i.e. a model object is drawn using a corresponding drawing object.

From reading the docs it seems that NSCell is a way to do simple  
drawing inside a parent NSView. However, it seems to centre around  
drawing images and text.

What I'm actually doing is trying to draw the axis of a graph. I have  
a simple model object that describes the axis (tic marks along an  
axis) and just want a graphical representation of it, e.g. a line  
with the tic marks at appropriate intervals. Have a look here for the  
model class, http://www.boyfarrell.com/code/chocplot/doc/

I was hoping to have a simple drawing class that I can initialise  
with my axis model, such that it will draw in the appropriate place  
on my NSView.

Cheers,

Dan.
