) Sorted by what, in what language using what facilities?  The only way
) to do this right is probably to add the ability to tuck a pointer in
) associated with each list item, and then be able to add one (or better
) yet, N) compare functions to the list to be used when items are added.
) I just layered that on top of the existing List.  List has enough troubles
) right now without adding more functionality.

) As for XmText.  Doing full international support is non-trivial, although
) the Mac does do it now.  But OSF has nowhere near the resources that
) Apple has.  I must say though, anyone who thinks that multi-font output,
) and support for multi-megabyte text (which the Mac does *not* do in their
) text edit widget) has to be slow should go use Apollo's Display Manager.

I have to agree with this.  Although we have implemented sorted lists
in a set of specific instances in our application, it is not easy to
do generally.  Throw in international support and it becomes an
exercise in futility.  I think the diverse needs required in sorted
lists, even for the simple cases, makes this a feature best left to
the programmer on a case by case basis.
