Custom NSCell - iTunes Source List

Hi everyone,
I have a seemingly huge challenge for a newbie such as myself. I am trying
to create an editable "Source List" ala itunes. Apple is using this a lot
and I have seen a few people asking but have found few answers.

My Question:
I am working towards this - I have a NSCell subclass that draws an image -
but how on earth do I draw a NSTextField into the same custom cell. And
control the size of the edit frame all programatically.

The Goal:
1 custom NSCell (that I can attach to a tableview) with an Image and with an
editable NSTextField.

The text field must have an edit rectangle the same size of the text(which
varies). (just like itunes if, a playlist name consists of 1 char then the
edit box is really tiny).

Granted I can do this with 2 separate cells (although I would love to learn
how to "compose" a control out of multiple elements, but I still have no
idea how to control the edit frame for the text field.)

I have looked into field editors & setting up field editors and have been
barking up the wrong tree (IMHO) it seems I need standard field editor
behavior - just the size of the frame of what is being edited is my problem.

Any help/comments/info will be rewarded 1000000 karma credits (redeemable in
your next life). Bonus points for a link to sample code somewhere on the
dang web.
