Here's my samples from my notes directory. There's one for curses and
one that does a couple of ways of using dialog, the latter way uses a
dialog module I wrote and include at the end. The module takes care of
packing the strings that go to the dialog command line making the main
program line clean and neat.
Disclaimer: I've only used this a couple of times since most of my
stuff uses normal text i/o.

#dialog.py
"""
Module wrapper for /usr/bin/dialog. See man page.
Options for dialog are attributes of a dialog instance.
e.g. instead of adding --title, do:
obj.title=' --title "This is the title" '
Remember to include a trailing space in each attribute
method pack() returns the complete dialog to run
using:
Dialog_CMD=dialog.show()
w,r = os.popen4(Dialog_CMD)
This allows access to stdin and stdout/stderr. Guage bars, for
example, read from stdin until get EOF.
