NSCell rollover

Subject: NSCell rollover

I'm attempting to create an NSCell to be used in a tableView similar to the "Eject" icon in iTunes, Finder, etc. I've got an NSImageCell? subclass, and I'm dealing with changing the image depending on if the row is selected in my controller. However, I can not for the life of me figure out how to implement the rollover effect for my cell. I've got some mouse tracking set up in my tableView, and I've determined the row and column using rowAtPoint: and columnAtPoint:, but I can't figure out how to refer to the cell that is under the mouse. I know that NSTableView provides a way to get the NSRect for the cell at the intersection of a row and column, but I'm not sure exactly how to use that information.
