-- - "color_set"
-- procedure Handler (Button : access Gtk_Color_Button_Record'Class);
-- The color-set signal is emitted when the user selects a color. When
-- handling this signal, use Get_Color and Get_Alpha to find out which
-- color was just selected.
-- Note that this signal is only emitted when the user changes the color.
-- If you need to react to programmatic color changes as well, use the
-- notify::color signal.
