2001-04-03  Richard Hult  <rhult@codefactory.se>

	* e-tree.c (et_get_arg): Add argument to get the table adapter.
	(et_set_arg): Add arguments for setting drawing of the grid and
	focus.

	* e-tree-model.c, e-tree-model.h (e_tree_model_node_traverse):
	Fill in missing implementation.
	(e_tree_model_node_traverse_preorder): Likewise, but preorder
	traversal.
