Dear Huw,
Keith is certainly right that tkFileDialog is very useful. But you may
want to know an answer to your original question too.

If I understand your question correctly, you want to replace the
contents of a listbox with a new list of items. All you have to do is
delete the old items and add some new ones:

self.lb.delete(0, END) # clear
for item in myList:
  self.lb.insert(END, item)

I swiped that code pretty well directly from Fredrik Lundh's excellent
introdcution to Tkinter, which is at:

If you haven't had a look at it, you may want to.

You might also want to have a look at Greg MacFarlaine's cool Pmw
(Python megawidgets):

His ScrolledListBox widget will save you a step here since it has a
setlist() method.
