WAPLEt was designed * as an applet so it overrides certain mehtods to do its painting and updating * of the screen.  It also calls the function init() when first loaded to * handle initializations.  These routines have been maintained and upgraded so that * they can work under a normal Java Application format.  Many of the * routines have been changed to reflect this. For example, in the init() routine * references to the "this" pointer have been replaced with this.getContentPane, since * the JFrame class does not support access to itself directly.  All Graphical controls * must be added to the contentpane.  Routines where added to provide more functions to the * class, shuch as routines for calling up a popup menu, or even routines accessible * by the WAPIDE class to make changes in that class as well as allow the WAPIOE * class access to certain simulator functions. * * Some routines of WAPLET that where maintained where also changed so as to provide * more functionality to the browser.  For example, do links of types "accept" and "unknown" * are now supported and take preference over the anchor tag.  In the future * I hope to add even more functionality to the browser, making it fully compliant with * the specifications laid fown by the WAPForum. * * Skinning support has been added, and skins created by the PhoneDesigner class in the * Designer package can be loaded into the Simulator interactively.  Eventually, menu support * will follow so that the Simulator will be able to mimick any phone on the market. * Copyright: Copyright (c) 2003 * @author Mark Busman * @version 1.0 * Contact Info: cougar@skyinet.net * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If constructor (filename, skin, menu, toolbar) is *   used then right clciking on the simulator does not popup the popup menu, instead *   the options of the peopup menu must be selected in the WAPIDE class * * Feb 8, 2003 * - added main() function * - performed tests * * Feb 9, 2003 * - Final integration test -- SUCCESSFUL *******************/public class Simulator extends JFrame implements ActionListener, MouseListener{  private JPopupMenu navPopupMenu = new JPopupMenu();  private JMenuItem navBack = new JMenuItem();  private JMenuItem navHome = new JMenuItem();  private JMenuItem navRefresh = new JMenuItem();  private JMenuItem navReload = new JMenuItem();  private JMenuItem navStop = new JMenuItem();  private JMenuItem navLocation = new JMenuItem();  private JMenuItem navFile = new JMenuItem();  private JMenuItem navSkin = new JMenuItem();  private GridBagLayout gridBagLayout1 = new GridBagLayout();  private JPanel mainPanel = new JPanel();  private JLabel BKGround = new JLabel();  private JMenuItem navSkinDefault = new JMenuItem();  // User Variables  /////////////////////////////////////////////////////////////////////////////  // Original Copyright notice of WAPLET  /////////////////////////////////////////////////////////////////////////////  ///* attention decompilers */  //static String copyright =  //      "this code and all related object, binary and bytecode " +  //	"compilations are copyright (c) 2000 pagea company.
