    /// Depending on the situation, colors may be allowed to have alpha (translucency).

    ///

    /// The property can be set to change the current selection
    /// programmatically.

    /// Readable | Writeable
    ///

    /// #### `use-alpha`
    ///  Whether colors may have alpha (translucency).
    ///
    /// When ::use-alpha is [`false`], the [`gdk::RGBA`][crate::gdk::RGBA] struct obtained
    /// via the [`rgba`][struct@crate::ColorChooser#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).
    ///
    /// Readable | Writeable
    ///
    /// ## Signals
    ///
    ///
    /// #### `color-activated`
    ///  Emitted when a color is activated from the color chooser.
    ///
    /// This usually happens when the user clicks a color swatch,
