2000-04-24 Miguel de Icaza <miguel@helixcode.com> * e-table.c (e_table_class_init): Add argument handling here. * e-table-group-leaf.c (e_table_group_apply_to_leafs): New method. Enables us to walk all the children of an ETableGroup. * e-table.c (et_get_arg, et_set_arg): Implement ::get and ::set methods. (e_table_construct_from_spec_file): Now we return the etable. (e_table_construct): ditto. (et_real_construct): Now we return the ETable. Returns NULL on construct failure. (e_table_new): ditto. (e_table_new_from_spec_file): ditto. * (et_build_grouping_spec): Removed vestige code that still contained references to the etable->specification XML code. Dumped all the ifdefed out code. * e-table.h: Removed ETable->specification finally. svn path=/trunk/; revision=2632
