Listening for fragment changes in the browser address with Jxbrowser - jxbrowser

Question

I would like to listen for address changes. So far I have been able to use:
browser.addStatusListener((StatusEvent event) -> {
listener.handle(browser.getURL());
});
To create my own handler which is called when the address changes. But I just discovered that this approach does not work when an fragment is added to the address. E.g. a change from "http://example.com" to "http://example.com#hello" won't result in a StatusEvent. How do I archive this with JxBrowser?

The StatusListener class is not designed for tracking address changes.
In order to handle current browser URL changes, I suggest that you register your custom LoadListener and listen the DocumentLoadedInMainFrame event which indicates that a new document with a new URL was loaded in Browser instance. After you caught the DocumentLoadedInMainFrame event, you can get browser URL invoking the Browser.getURL() method. Please take a look at the code sample below:
import com.teamdev.jxbrowser.chromium.Browser;
import com.teamdev.jxbrowser.chromium.events.LoadAdapter;
import com.teamdev.jxbrowser.chromium.events.LoadEvent;
import com.teamdev.jxbrowser.chromium.swing.BrowserView;
import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import javax.swing.WindowConstants;
public class LoadHandlerSample {
public static void main(String[] args) {
Browser browser = new Browser();
BrowserView view = new BrowserView(browser);
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(view, BorderLayout.CENTER);
frame.setSize(700, 500);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
browser.addLoadListener(new LoadAdapter() {
#Override
public void onDocumentLoadedInMainFrame(LoadEvent event) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
System.out.println("Document loaded: " + event.getBrowser().getURL());
}
});
}
});
browser.loadURL("http://www.google.com");
}
}
