New functions for saving selection state and such.
2002-01-15 Christopher James Lahey <clahey@ximian.com> * e-cell.c, e-cell.h (e_cell_save_state, e_cell_load_state, e_cell_free_state): New functions for saving selection state and such. * e-cell-text.c (ect_save_state): Implemented the new state functions. * e-table-item.c, e-table-item.h: Use the new cell state functions when focusing in or out. Fixes Ximian bug #14968. svn path=/trunk/; revision=15335
