Added e-selection-model-array.lo.
2001-03-25 Christopher James Lahey <clahey@ximian.com> * gal/Makefile.am (libgal_la_LIBADD): Added e-selection-model-array.lo. * gal/widgets/Makefile.am: Added e-selection-model-array.c and e-selection-model-array.h. * gal/widgets/e-selection-model-array.c, gal/widgets/e-selection-model-array.h: New class that implements the details of ESelectionModel. ESelectionModel has been refactored to just be a this virtual class. ESelectionModelArray is the original implementation of ESelectionModel. This is what most people will want to use or derive from. * gal/widgets/e-selection-model-simple.c, gal/widgets/e-selection-model-simple.h: Made the parent class of this be ESelectionModelArray instead of ESelectionModel. Changed some function names to match this change. * gal/widgets/e-selection-model.c, gal/widgets/e-selection-model.h: Refactored most of the implementation of this class into ESelectionModelArray. Now just a thin virtual class. From gal/e-table/ChangeLog: 2001-03-25 Christopher James Lahey <clahey@ximian.com> * e-table-selection-model.c, e-table-selection-model.h: Made the parent object of this be ESelectionModelArray instead of ESelectionModel due to their refactoring. Changed the commented out code for saving the selection a bit. svn path=/trunk/; revision=8924
