All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible, javax.swing.RootPaneContainer, javax.swing.WindowConstants, TurtleListener

public class TurtleField
extends javax.swing.JFrame
implements TurtleListener

Rudimentary view showing turtles and MVC. Illustrates simple Model/View decomposition, not meant as an example of what a real Slogo view would be. In this implementation the View creates the Model/JTurtle object.
