I would like to set the text color of the cell in an NSTableView

changing working right now in "willDisplayCell". What I am not sure
about is how to (1) retrieve a column for the same row to check the
data for a cell, or (2) check the associate array controller being
used to populate the cell data to see if a different field has
related data.
For example, while viewing the "Name" column in "willDisplayCell", I
also want to see the other data that it is associated to -- perhaps
not all the data is displayed in the NSTableView.
Thoughts?
Hi Bryan,
The row index usually represents the array index of the item in the
data model, and the column is a property for that item. Therefore the
rowIndex is all you need to retrieve *all* of the data for an object,
whether the table displays it or not. Both the column and the row
index are passed to the delegate method you mention.
You ask: "how to (1) retrieve a column for the same row" but that
doesn't make any sense - the column being drawn is passed to you, and
there isn't a "column for the same row". Columns and rows are, quite
literally, orthogonal.
