What I'm saying is you should put the header and body pieces into a Pile
in the ListBox so that the ListBox will always try to keep the whole
thing visible. If you are doing special things with the listbox's focus
to create different effects, consider making a custom widget that can
handle the keypresses, like this:
class EmailWidget(urwid.WidgetWrap):
def __init__(self, email):
self.__super.__init__(urwid.Pile( ..header, parts of email.. ))
def keypress(self, size, key):
# special handling here, manipulating self._w (the pile)
# or its contents
