Direct Known Subclasses:
HScale, VScale
public abstract class Scale
extends Range

A slider control which allows the user to manipulate a numeric value. As with many other Widget hierarchies in GTK, there is a horizontal (HScale) and vertical (VScale) implementation for you to choose from.

The default position for the value to be displayed is TOP which may not be quite what you want. Use setValuePosition() to change it.

Otherwise, most of the useful methods (notably those relating to the value) are inherited from the parent class, Range.
