Leon,
If you go to the WOInfoCenter and search for EOQualifier and go to
the EOQualifier documentation, you should find a link to constructing
qualifiers which covers programmatic creation of qualifiers. After creating
a qualifier and fetchSpecification, you can get objects from the database by
asking [anEditingContext objectsWithFetchSpecification:myFetchSpec], or, if
you have a WODisplayGroup with an EODatabaseDataSource, you can set your
qualifier on the dataSource's fetchSpecification and then tell the
displayGroup to fetch.
Regards,
Paul
