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. svn path=/trunk/; revision=6156
