2001-04-12 Christopher James Lahey <clahey@ximian.com> * configure.in: Upped the version number to 0.6.99.0. Upped the so number to 6. * docs/etablexml.txt: Made some updates here. * tests/test-tree-1.c, tests/test-tree-3.c: Added NULL, NULL to the call to e_tree_memory_callbacks_new. From gal/e-table/ChangeLog: 2001-04-12 Christopher James Lahey <clahey@ximian.com> * e-table-item.c (eti_cursor_change): Only move the screen to show the cursor if there are no changes pending. Updated the commented out code for alternating colors a bit. * e-table-model.c, e-table-model.h: Added e_table_model_has_change_pending. * e-tree-memory-callbacks.c, e-tree-memory-callbacks.h: Added has_get_node_by_id and get_node_by_id. * e-tree-model.c, e-tree-model.h: Added e_tree_model_has_get_node_by_id and e_tree_model_get_node_by_id. Added e_tree_model_has_change_pending. * e-tree-selection-model.c: Handle the selection and cursor properly across the tree changing. * e-tree-sorted.c: Implemented has_get_node_by_id and get_node_by_id, and has_changes_pending. * e-tree-table-adapter.c: Implemented has_changes_pending. Fixed an array underflow. svn path=/trunk/; revision=9289
