Fixes Ximian bug #6832.

2001-10-25  Federico Mena Quintero  <federico@ximian.com>

	Fixes Ximian bug #6832.

	* e-table.c (e_table_setup_table): Use a callback instead of
	gtk_widget_queue_draw() for focus events, as the latter does not
	have the correct prototype for an event handler.
	(group_start_drag): Emit START_DRAG, not KEY_PRESS!
	(focus_first_etable_item): Focus the first row in the first
	ETableItem if there is no focused item.

	* e-tree.c (e_tree_setup_table): Same change as in
	e_table_setup_table().
	(table_canvas_focus_event_cb): Focus the first row in the tree
	item if there is no focused item.
