Toggle Button - Super Simple

This demo shows you how to make a toggle button using 2 methods.

1. A Button that changes color and text
2. A Button with a graphic that changes

It's a simple way to get a toggle button in PySimpleGUI using the Button Element.

Toggle Button - Super Simple Graphic Only

And this one is even more simplified.

Toggle Button - Simple Graphic - No Button Animation

Maybe you don't want the graphic to move up and down like a button does. Not a problem....just switch from Button to Image.
