Direct Slots

rgba

The rgba property of type gdk-rgba (Read / Write)
The rgba property contains the currently selected color, as a RGBA color. The property can be set to change the current selection programmatically.

use-alpha

The use-alpha property of type :boolean (Read / Write)
When use-alpha is true, colors may have alpha (translucency) information. When it is false, the RGBA color obtained via the rgba property will be forced to have the alpha value 1.0. Implementations are expected to show alpha by rendering the color over a non-uniform background (like a checkerboard pattern).
Default value: true

Details

The gtk-color-chooser interface is an interface that is implemented by widgets for choosing colors. Depending on the situation, colors may be allowed to have alpha (translucency).

The main widgets that implement this interface are gtk-color-button, gtk-color-chooser-widget, and gtk-color-chooser-dialog.
