Added selection_mode argument.
2001-01-11 Christopher James Lahey <clahey@helixcode.com> * e-table-selection-model.c, e-table-selection-model.h: Added selection_mode argument. * e-table-specification.c, e-table-specification.h: Added a selection_mode field that is set based on the selection-mode attribute in the ETableSpecification element. * e-table.c (et_real_construct): Set the selection model's selection mode based on the ETableSpecification. svn path=/trunk/; revision=7427
