use_alpha


Description:

[ ConcreteAccessor ]
public abstract bool use_alpha { get; set; }

Whether colors may have alpha (translucency).

When GtkColorChooser::use-alpha is false, the `GdkRGBA` struct obtained via the [ [email protected]:rgba] property will be forced to have alpha == 1.

Implementations are expected to show alpha by rendering the color over a non-uniform background (like a checkerboard pattern).
