Hmm...loks like those are gone already. At least, all I get is a
compiler warning that those methods do not exist and searching the
header files shows me nothing.
Oh, well. Nice try.
Thanx,

On a side note, I'd like to add a little sort up/down arrow to my
table column headers to show my current sort direction for that
column. Where can I hook to do this? Is there a character for these
arrows, or will I have to use NSBezierPath to draw it?
To set an image in a table column, use [NSTableView
setIndicatorImage:inTableColumn]. Currently, there are two undocumented
selectors on NSTableView, _defaultTableHeaderSortImage and
_defaultTableHeaderReverseSortImage. These return up and down arrows.
So, to set the correct image in your table, do something like the
following:
if (ascending)
[table setIndicatorImage:[NSTableView
_defaultTableHeaderSortImage] inTableColumn:sortColumn];
else
[table setIndicatorImage:[NSTableView
_defaultTableHeaderReverseSortImage] inTableColumn:sortColumn];
Of course, those two selectors may disappear in the future, so you
should do a runtime check to make sure they are there.
