public class VRMLBrowserAWTPanel

extends java.awt.Panel

implements VrmlComponent, BrowserComponent, org.j3d.ui.navigation.ViewpointSelectionListener

A brower that uses the AWT panel and labels to draw render the UI with.

VRMLBrowserAWTPanel is the AWT based alternative to BrowserJPanel. At the moment, it offers minimal functionality. The "dashboard" is a text label, there aren't any navigation functions. That, and urlReadOnly, urlTop, and dashTop are ignored.

                           boolean urlReadOnly,
                           boolean showConsole)

Create an instance of the panel configured to show or hide the controls and only shows VRML97 content.

Parameters:

showDash - true to show the navigation bar

dashTop - true to put the nav bar at the top

showUrl - true to show the URL location bar

urlTop - true to put the location bar at the top

urlReadOnly - true to make the location bar read only

showConsole - true if the console should be shown immediately

VRMLBrowserAWTPanel

public VRMLBrowserAWTPanel(boolean vrml97Only,
                           boolean showDash,
                           boolean dashTop,
                           boolean showUrl,
