A python example of a Pashua prompt window for changing passwords. It is just an example and doesn't actually change passwords.

change_password_pashua.py

#!/usr/bin/python
#
# Simple python example of a Pashua password prompt window for changing passwords.
# It prompts for the current password, new password, and new password verification.
# It does the verification and redisplays the prompt with feedback if the current or
# new passwords do not match.
#
# THIS WILL NOT ACTUALLY CHANGE PASSWORDS. I created this as an example of how you can
# design Pashua dialogs and work with their output.
#
# For easiest testing, you should have the Pashua.py connector and Pashua.app
# in the same directory as this script.
#
# The current password is 'password'.
