2001-03-30  Christopher James Lahey  <clahey@ximian.com>

	* e-table-group.c, e-table-header-item.c, e-table-item.c,
	e-table.c, e-tree.c: Made these use GTK_TYPE_GDK_EVENT whenever
	sending an event through the signal system instead of
	GTK_TYPE_POINTER.

	* e-table.c, e-tree.c (set_header_canvas_width): Check that none
	of the variables we're going to need are NULL before executing
	this function.
