public class BrowserController

extends javax.swing.JFrame

implements java.awt.event.ActionListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener

The controller of the browser. This class is responsible for reacting on the events that are generated when the user clicks the buttons or move the mouse. The controller uses a BrowserModel to handle the logic associated with navigating forward and backward. A DocumentView is created as needed to display the DocumentModel returned by the Parser.
