given (from your example)

		self.items = [ location, urwid.Divider(),
                                look_row, exits_row ]
		self.listbox = urwid.ListBox( self.items )

if I simply self.items.append(x), I should get one additional row which 
I can then delete at some other time?  in fact, it should be possible to 
completely replace all of the elements in the items array if I should 
see fit.

okay, I'll try that.
