gtk-color-button-alpha (object)

object -- a gtk-color-button widget
alpha -- an integer between 0 and 65535

Accessor of the alpha slot of the gtk-color-button class.

The slot access function gtk-color-button-alpha returns the current alpha value. The slot access function (setf gtk-color-button-alpha) sets the current opacity to be alpha. The gtk-color-button-alpha function has been deprecated since version 3.4 and should not be used in newly written code. Use the gtk-color-chooser-rgba function instead.
