Swing Web Browser problems

[Jack Fletcher]

Hi guys,

I'm trying to create a simple web browser using Swing and AWT.
So far I only have the basic structure written and plan to add more but I have encountered a pitfall in that when my code is run I am presented with two windows.
One is sized properly and has no title, the other has the correct title of 'My Web Browser' but is not sized and neither display the components which I have added eg. the JEditorPane to display the html page.

My code is below I would appreciate any points in the right direction!
Thanks.

import java.awt.event.*;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.*;
import javax.swing.event.HyperlinkListener;

public class BrowserFrame {
	
	// Components:
	private JFrame frame;
    private JPanel panelTop;	    
    private JEditorPane editor;
    private JScrollPane scroll;
	private JTextField addressBar;
	private JButton goButton;
	private URL url;
	
	// Constructor -----
		public BrowserFrame()
		{
			// Set the frame title
			super("My Web Browser");

			frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
			
			// Add top panel to top of the frame
			frame.add(BorderLayout.NORTH, panelTop);
			
			// Add address bar and go button to the top panel
			panelTop.add(addressBar);
			panelTop.add(goButton);
			
			// Add scroll pane to frame centre
			frame.add(BorderLayout.CENTER, scroll);

	    	catch(IOException ioe)

Have you tried a JEditorPane with editable set false? Try here for a tutorial.

I shall move your post to the GUIs forum.
