All Implemented Interfaces:

java.io.Serializable
```
public class SquareClassificationWidget
extends ClassificationWidget
```
This class implements a 2D Square-shaped ClassficiationWidget. The code implements the rendering of the widget in the 2D Multi-histogram panel, as well as the user mouse-interaction with the widget. The parameters that define the widget are then passed to the Volume Renderer GLSL shader program and determine how the Volume is displayed. *
