Oops :-), good catch Terry! I had copy-pasted the OP's original method however i forgot to remove the "self" parameter; then i had to convert my Python2.x code into 3.x code, which was not terribly difficult, however, this "pit stop" was distracting enough that I forgot to click the button while testing.

My example does not bind the "KeyPress-ReturnKey" to any callback, so what were you expecting to happen when you pressed enter?

Well it's as complete as it needs to be :-). Any more complete and it would less of a teaching exercise and more of a "copy-paste" exercise. I did not want to just gift wrap an answer for the OP. My hope is that he has the basic skills to turn that incomplete example into useable code. If not, well, then he needs to study that tutorial link i sent early in the thread.
