pack(fill=BOTH, expand=1) should do the trick.

the pack geometry manager works by slicing off vertical or horizontal areas from
the parent, one area per widget.  the "fill" option controls how to place the widget
inside that area, the "expand" option controls how to handle any extra space left
in the parent.  if "expand" isn't set for any child widget, the extra space is left un-
used.
