Expand description

Something that can be used as the background for a widget.

This represents anything that can be painted inside a widgets paint method; that is, it may have access to the Data and the Env.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
