when I run this, and click the button, I get
Exception in Tkinter callback
Traceback (most recent call last):

TypeError: cbButton() missing 1 required positional argument: 'self'
when I remove 'self' from cbButton, I get the expected
I should do something here!
When I enter something in the Entry box and hit return, nothing happens.
I presume that is because the example is not complete.
