All Implemented Interfaces:

```
public class RJThumbWheel
extends javax.swing.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.
