public final class ListSortUI extends Object
ListSortUI provides support for managing the synchronization between RowSorter, SelectionModel and ListModel if a JXList is sortable.This implementation is an adaption of JTable.SortManager fit to the needs of a ListUI. In contrast to JTable tradition, the ui delegate has full control about listening to model/selection changes and updating the list accordingly. So it's role is that of a helper to the ui-delgate (vs. as a helper of the JTable). It's still up to the ListUI itself to listen to model/selection and propagate the notification to this class, if a sorter is installed, but still do the usual updates (layout, repaint) itself. On the other hand, listening to the sorter and updating list state accordingly is completely done by this.
