+2000-09-01 Chris Toshok <toshok@helixcode.com>
+
+ * e-tree-model.h: add signals/prototypes for
+ e_tree_model_node_collapsed and e_tree_model_node_expanded.
+
+ * e-tree-model.c (etree_set_expanded): emit
+ node_expanded/node_collapsed signals, with node_expanded happening
+ before the expansion so it can much with the children, and
+ collapsed being emitted after.
+ (e_tree_model_row_of_node): remove stupid check, and g_warning.
+ (e_tree_model_node_collapsed): new function.
+ (e_tree_model_node_expanded): new function.
+
2000-08-31 Christopher James Lahey <clahey@helixcode.com>
* e-table-selection-model.c: Made the selection work when shift
