I played a bit with the CustomButton in Xojo 2021 R2.1, renaming it to Open and adding an icon.
The result in the app is not what the IDE showed:
From top to bottom:
- CustomButtons with an icon assigned and an orange background
- CustomButtons with an icon assigned and a white background
- CustomButtons without an icon assigned but with an orange background
- A BevelButton with the same caption and icon
Am I missing something here? Because I was expecting a bug report having been logged, but nada.
