beginning of the keyboard navigation.
1999-11-27 Miguel de Icaza <miguel@gnu.org>
* e-table-item.c (eti_event): beginning of the keyboard navigation.
* e-table-model.c (e_table_model_row_changed): new function.
(e_table_model_cell_changed): new function.
(e_table_model_class_init): New signals.
* e-table-item.c (eti_request_region_redraw): x2, y2 offsets were
wrong.
(eti_select): Repaint selected region.
(eti_request_region_redraw): Fix range.
(eti_draw): Correct offset computation here.
(e_table_item_class_init): New method: row_selection, handles the
selection.
Now it implement GTK_SELECTION_SINGLE and GTK_SELECTION_MULTIPLE.
Focusing and selection should be correct now.
