gtk:scale-button-value (object)

object -- a gtk:scale-button widget
value -- a double float with the value of the scale button

Accessor of the value slot of the gtk:scale-button class. The gtk:scale-button-value function gets the current value of the scale button. The (setf gtk:scale-button-value) function sets the current value.

If the value is outside the minimum or maximum range values, it will be clamped to fit inside them. The scale button emits the "value-changed" signal if the value changes.
