This is just a prettied up version of what’s in NSTableViewRollover. (Moved from CCDSourceTable.)

Your delegate should look something like this…
(void)tableView:(NSTableView *)aTableView willDisplayCell:(id)aCell forTableColumn:(NSTableColumn *)aTableColumn row:(int)rowIndex { if ([aCell type] == NSTextCellType && [aCell respondsToSelector:@selector(setTextColor:)]) {
if ([aTableView editedRow] == rowIndex) [aCell setTextColor:[NSColor blackColor]];
else
if ([aTableView selectedRow] == rowIndex) [aCell setTextColor:[NSColor whiteColor]];
else
[aCell setTextColor:[NSColor blackColor]];
} }
Without a custom fieldEditor editing isn’t going to work exactly like it does in iTunes but I think I’ve got it pretty close here.
Fixed a glitch. My bad.
—-Discussion—-
Looks great! However theres a pretty decent bug at least on Mac OS X 10.4.2 where when you load the Sample app with the iTunes like table and everything looks good, then you switch to another window or app and take the focus away from the app with the table and the Header title disappears, when you bring focus back to the app it works just like before except the title is gone. Anybody else get this? I’ve tried this in my app and in the sample app and it’s reproducable 100% of the time for me so far.
I, too, am getting that bug, but for my uses, I didn’t really like the whole textured header thing anyway, so I just used the regular Aqua header. I never really attempted to chase down the cause. I suspect that if you were to use needsDisplay: on it, when it becomes firstResponder, then that would force it to redraw, and get around the issue, but it may not help figure out the original cause. Someone, please correct me if I’m wrong. – JasonTerhorst
Sounds like the header view isn’t getting its notifications. shrug
