public abstract class Range
extends Widget

Base class for Widgets which present an adjustable quantity in some form of slider. The most obvious feature of this class is the ability to manage the "value" being shown by the Widget, but there are also facilities for exercising fine-grained control over the behaviour of the Widget when the user attempts to adjust the slider.

4.0.6
