Re: how to do the date control (found in Carbon) in Cocoa?

You may need to do this one yourself.  If you don't mind having the
stepper in a separate cell from the text cell, there is an
NSStepperCell class that would give you easy stepper functionality and
perhaps just use an NSFormatter to accomplish the date formatting in an
adjacent text cell.

If you really need both parts in a single cell, you could write your
own subclass of NSCell that would include an NSStepperCell and one or
three NSTextFieldCells.  I recommend looking at the ImageAndTextCell
class included in "/Developer/Examples/AppKit/DragNDropOutlineView/". 
This may be a big step for a fresh Cocoa programmer, so if you have any
trouble feel free to get back to me.
