Indeed, that was the problem . Congrats! Your first GUI program .
Feels quite glorious, seeing as this is not as common-sense oriented as the .NET suite.
A last question, I've been searching, but do you have a link that could show me some common tricks with the interface widgets? Such as using an entry field to obtain user-input and output that to a variable. I assume it's something like my_var = entry1.text, but am unsure of the exact syntax and how to even make it a declared widget like the button. Just need a very simplified guide to set me on my way now that I can get the GUI to function. )
