make ETreeModel opaque, and switch from using g_new0 and g_free for
2000-10-24 Chris Toshok <toshok@helixcode.com>
* e-tree-model.c: make ETreeModel opaque, and switch from using
g_new0 and g_free for ETreePath's to using g_mem_chunk routines.
(e_tree_model_node_remove): free the path's save_id. *
(e_tree_model_set_expanded_default): add method to add default
expanded status for parent nodes.
(etree_set_expanded_recurse): make this more efficient.
e-tree-model.h: make ETreeModel opaque. add prototype for
e_tree_model_set_expanded_default.
