Demo Toggle Buttons created using PIL
|
|
|
|
A BIG thank you to @jason990420 for his talented work creating this demo.
|
|
|
|
Demonstrates how you can draw buttons rather than using the built-in buttons
|
|
with the help of the PIL module.
|
|
|
|
One advantage is that the buttons will match your window's theme.
|
|
|
|
You'll find more PySimpleGUI programs featured in
|
|
Mike Driscoll's PIL book - "Pillow: Image Processing with Python"
