add new files. set the right role. new file.
2003-10-11 Yuedong Du <yuedong.du@sun.com> * gal/a11y/e-table/Makefile.am: add new files. * gal/a11y/e-table/gal-a11y-e-cell.c: (gal_a11y_e_cell_construct): set the right role. * gal/a11y/e-table/gal-a11y-e-table-item-factory.c: new file. (gal_a11y_e_table_item_factory_get_accessible_type), (gal_a11y_e_table_item_factory_create_accessible), (gal_a11y_e_table_item_factory_class_init), (gal_a11y_e_table_item_factory_init), (gal_a11y_e_table_item_factory_get_type): factory for the table item a11y object. in create_accessible, we judge the type of widget then set correct role. * gal/a11y/e-table/gal-a11y-e-table-item-factory.h: ditto. * gal/a11y/e-table/gal-a11y-e-tree-factory.c: new file. (gal_a11y_e_tree_factory_get_accessible_type), (gal_a11y_e_tree_factory_create_accessible), (gal_a11y_e_tree_factory_class_init), (gal_a11y_e_tree_factory_init), (gal_a11y_e_tree_factory_get_type): factory for a11y object of etree. Mostly copyed from gal-a11y-e-table-factory.c. * gal/a11y/e-table/gal-a11y-e-tree-factory.h: ditto * gal/a11y/e-table/gal-a11y-e-tree.c: (init_child_item), (et_ref_accessible_at_point), (et_get_n_children), (et_ref_child), (et_class_init), (et_atk_component_iface_init), (et_init), (gal_a11y_e_tree_get_type), (gal_a11y_e_tree_new):a11y object for etree object, mostly copied from gal-a11y-e-table.c. init_child_item set correct role for the table item. * gal/a11y/e-table/gal-a11y-e-tree.h: ditto. * gal/e-table/e-table-item.c: (eti_class_init): register factory for table item a11y object. * gal/e-table/e-tree.c: (e_tree_get_item), (e_tree_class_init): add new access fuction to get the table item of etree. * gal/e-table/e-tree.h: ditto svn path=/trunk/; revision=22867
