Interface

GtkColorChooser

Description [src] 

interface Gtk.ColorChooser : GObject.Object

GtkColorChooser 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 GtkColorChooserWidget, GtkColorChooserDialog and GtkColorButton.
