Class Scale

public abstract class Scale extends Range

A Scale is a slider control used to select a numeric value. To use it, you'll probably want to investigate the methods on its base class, {@link Range}, in addition to the methods for Scale itself. To set the value of a scale, you would normally use {@link Range#setValue(double)}. To detect changes to the value, add RangeListener object to the widget.

The GtkScale widget is an abstract class, used only for deriving the subclasses {@link HScale} and {@link VScale}.
