Stupid question:

I have a TIB_Grid and the user can sort and search on most of it's columns.
How do I sort the table on multiple columns using the
TIB_Query.OrderingItems property. For example, the table contains the
following rows (ordered by FIRSTNAME):

FIRSTNAME LASTNAME
Jacques Villeneuve
Michael Schumacher
Ralf Schumacher
Rubens Barrichello

If the user then orders the table by LASTNAME, the FIRSTNAME column must
still be sorted, for example:

FIRSTNAME LASTNAME
Rubens Barrichello
Michael Schumacher
Ralf Schumacher
Jacques Villeneuve

By looking at the sample applications it looks like I should be able to do
it through TIB_Query.OrderingItems, but how?
