Now I'm all confused. Everything's working now where it wasn't before.
I'm having the desired result (selected cell not appearing selected) by
following Corbin's original advice:
override NSTable's -hightlightSelectionInClipRect: to do nothing & having
the delegate method
- tableView:willDisplayCell:forTableColumn:row: perform setHighlighted:NO
& setBackgroundStyle:NSBackgroundStyleLight on the cell.
I'm getting backColor text as desired.
Also, if I send [cell setHighlighted:NO], the cell's
-highlightColorWithFrame:controlView: is not called, shao wholesale
subclassing of cells does not appear to be needed.
My guess as to what I had wrong before was that I had set hightlight style
to "source list" in IB when exploring & had not set it back to normal. I'm
testing now with a programmaticly generated NSTableView.
Thanks for all your help.
