Here is a code snippet I have pulled out of the project. It is as bare bones
as I can make it to get the point across.
the problems I am having:
1. I would really like the window to be centered in the user's screen, but
setting the geometry doesn't place it there. (that isn't included here)
2. When I click the Login button, nothing happens. I know I am missing
something but it just isn't obvious what it is.
3. Finally, I would like to be able to hide the root window until the
authentication is performed, but root.hide() gets me a getattr error.
root.withdraw() works, but I can't get the root window back
Thanks for your help.
