If you're targeting Leopard, there is an NSTableView method you can
override for this (a public one!)
-(void)highlightSelectionInClipRect:(NSRect)theClipRect
Ideally this should be the only method you have to override for Tiger
also. You may have to coordinate with the cell (or use a custom cell)
to get the cell to not draw a conflicting highlight (hence, that is
why some people say to override _highlightColorForCell: -- this color
isn't used by NSTableView -- it is used by the cell)
You have to actually draw the highlights, it's not simply a matter
of setting the color. If you look at the post Ben linked to, there
is sample code you can download that will show you what to do.
The problem I am having with this is that it is leaving white spaces
between the columns, which correspond to where the grid lines would
be - I have them turned off. Is there anything I can do about that?
NSRect aRowRect = NSInsetRect([self rectOfRow:aRow], 2, 1);
Your insetting the width and height, hence you get spacing.
