/// Use [`ColorDialog`][crate::ColorDialog] and [`ColorDialogButton`][crate::ColorDialogButton]

/// [`ColorChooser`][crate::ColorChooser] is an interface that is implemented by widgets
/// for choosing colors.
///
/// Depending on the situation, colors may be allowed to have alpha (translucency).
///
/// In GTK, the main widgets that implement this interface are
/// [`ColorChooserWidget`][crate::ColorChooserWidget], [`ColorChooserDialog`][crate::ColorChooserDialog] and
/// [`ColorButton`][crate::ColorButton].
///
/// ## Properties
///
///
/// #### `rgba`
/// The currently selected color, as a [`gdk::RGBA`][crate::gdk::RGBA] struct.
///
/// 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,
/// or a color is selected and the user presses one of the keys
/// Space, Shift+Space, Return or Enter.
///
