thank you graham,
upon closer look i was in error to use the word tooltip. i have seen this
method before and tried it again and it does work to change the tooltip or
disable it. what i'm seeing must be some form of highlighting. although i
have disabled the standard highlighting where when you click the rows it
highlights. this is not my issue. it seems the rows that are truncated with a
tail are the ones that highlight when i hover my mouse over the row. on a row
that is not truncated it does not highlight. i have coded into my custom cell
setLineBreakMode:NSLineBreakByTruncatingTail. Maybe the issue lies somewhere
here?
edited: I just discovered this method:
- (NSRect)expansionFrameWithFrame:(NSRect)cellFrame inView:(NSView *)view
and returned NSZeroRect and seems that does the job. Assuming it does thank
you for your help you did get me on the right track!
Rick

tableView:toolTipForCell:rect:tableColumn:row:mouseLocation:
Returns a string that is displayed as a tooltip for aCell in aTableColumn of
aTableView.
- (NSString *)tableView:(NSTableView *)aTableView toolTipForCell:(NSCell
*)aCell rect:(NSRectPointer)recttableColumn:(NSTableColumn *)aTableColumn
row:(NSInteger)row mouseLocation:(NSPoint)mouseLocation
Discussion
The row is the row of the cell and aTableColumn is the NSTableColumn that
contains the cell. The rect represents the proposed active area of the tooltip.
By default, rect is computed as [cell drawingRectForBounds:cellFrame]. You can
modify rect to provide an alternative active area. Return nil or the empty
string if no tooltip is desired.
