Yes, take a look at -setObjectValue:. This point confused me for ages. You can bind the cell's value to whatever object you like, and in -setObjectValue: extract the relevant information into ivars for later use. > By way of further example, if you had a data model containing some objects > that have, say, an NSColor property, and you want to paint a simple colour > swatch in a custom cell, is there no simple way of binding the NSColor value > to the cell and picking this up in the cell?

There's no NSColorWellCell, unfortunately, or else this would be already done for you. Instead, just subclass NSCell, override -setObjectValue:, and implement -drawRect: appropriately. Make sure to call -[NSTableColumn setDataCell:].
