2001-02-27 Christopher James Lahey <clahey@ximian.com> * gal/Makefile.am: Added e-sorter.lo and e-selection-model.lo. * gal/util/Makefile.am: Added e-sorter.c and e-sorter.h. * gal/util/e-sorter.c, gal/util/e-sorter.h: New class. This is a new simple virtual class for use with ESelectionModel. It implements the same set of methods as ETableSorter but the default behavior is as if the sorting was a no-op. * gal/widgets/Makefile.am: Added e-selection-model.c and e-selection-model.h. * gal/widgets/e-selection-model.c, gal/widgets/e-selection-model.h: New class. Implements all of the semantics of ETableSelectionModel except for the connection to the ETableModel. svn path=/trunk/; revision=8421
