Hi Jochen,

JExplorer doesn't provide an appropriate API yet. We will add it in JExplorer 2.4 (January 2010). You can solve this issue right now by listenning opening and closing child windows using the following code:

import com.jniwrapper.win32.ie.Browser;
import com.jniwrapper.win32.ie.WebBrowser;
import com.jniwrapper.win32.ie.event.DisposeEvent;
import com.jniwrapper.win32.ie.event.DisposeListener;
import com.jniwrapper.win32.ie.event.NewWindowEventHandler;
 
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
 
public class CreateChildBrowserSample {
    public static void main(String[] args) throws Exception {
        final Map<Browser, java.util.List<WebBrowser>> browserChildren =
                new HashMap<Browser, java.util.List<WebBrowser>>();
 
        final Browser browser = new Browser();
        browser.navigate("http://www.google.com");
        browserChildren.put(browser, new ArrayList<WebBrowser>());
 
        final NewWindowEventHandler defaultHandler = browser.getNewWindowHandler();
        browser.setNewWindowHandler(new NewWindowEventHandler() {
            public NewWindowAction newWindow() {
                NewWindowAction action = defaultHandler.newWindow();
               
                 final WebBrowser childBrowser = action.getBrowser();
                java.util.List<WebBrowser> children = browserChildren.get(browser);
                if (children != null) {
                    System.out.println("Child added");
                    children.add(childBrowser);
                }
                // add dispose listener to remove child from map
                childBrowser.addDisposeListener(new DisposeListener() {
                    public void browserDisposed(DisposeEvent event) {
                        java.util.List<WebBrowser> children = browserChildren.get(browser);
                        if (children != null) {
                            System.out.println("Child removed");
                            children.remove(event.getBrowser());
                        }
                    }
                });
                return action;
            }
        });
 
        JButton print = new JButton("Print all children");
        print.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                java.util.List<WebBrowser> children = browserChildren.get(browser);
                for (WebBrowser child : children) {
                    System.out.println("child = " + child);
                }
            }
        });
       
         JFrame frame = new JFrame("JExplorer - Child Browser Sample");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(print, BorderLayout.SOUTH);
        frame.getContentPane().add(browser, BorderLayout.CENTER);
        frame.setSize(800, 600);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}
