All Implemented Interfaces:
ImageObserver, MenuContainer, Serializable
public class RJThumbWheel extends JComponent
This class has the behavior of a slider, without boundaries (so you can set values beyond the visible min and max). Furthermore, it has a 3D thumbwheel look, that is particularly nice for radial values. It also has an optional linear look, which is good for unbounded linear values.
