2001-10-22 Damon Chaplin <damon@ximian.com> * e-cell-text.[hc]: added set_value() class method, which sets the model value based on the text. In ECellText itself it assumes the model value is a char* and passes the text directly. Subclasses may parse the text into some other datatype. Also made the calls the e_cell_text_get_text(), e_cell_text_free_text() and e_cell_text_set_value() public, since we need them in ECellCombo. * e-cell-combo.c (e_cell_combo_select_matching_item): (e_cell_combo_update_cell): use e_cell_text_get_text()/free_text()/ set_value() so it can handle subclasses of ECellText as the child. svn path=/trunk/; revision=13901
