You've decided you need to get part codes when as far as I know there's no
reason to either need them or expect them. You're trying to make this a lot
more complicated than it is, though I don't know why.

I said previously that I wouldn't expect separate calls to a draw handler
for the different parts. Why do you expect that? I would expect to draw the
whole slider -- track, indicator, and tick marks -- in my kEventControlDraw
handler. In most multi-part controls with a modern Aqua look there are no
distinct boundaries between parts as a result of shadows and anti-aliasing.
As such isn't not reasonable IMO to expect to get a kEventControlDraw event
for individual parts. Although there could be exceptions, they would
definitely me exceptions.
It's your slider with your custom appearance. Draw the entire thing in your
kEventControlDraw handler and be done with it. This is very simple. Stop
making it complicated.
