gtk:color-selection-current-alpha (object)

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

Accessor of the current-alpha slot of the gtk:color-selection class. The gtk:color-selection-current-alpha function returns the current alpha value. The (setf gtk:color-selection-current-alpha) function sets the current opacity. The first time this is called, it will also set the original opacity to be alpha too. The gtk:color-selection-current-alpha function is deprecated since version 3.4 and should not be used in newly written code.
