    Details

    • Subcomponent:
      web

      Description

      Execute the following simple test that embeds a web view into Swing:

      import javafx.application.Platform;
      import javafx.embed.swing.JFXPanel;
      import javafx.scene.Group;
      import javafx.scene.Scene;
      import javafx.scene.web.WebEngine;
      import javafx.scene.web.WebView;

      import javax.swing.JFrame;
      import javax.swing.SwingUtilities;

      public class EmbedWebView
      {
          private static void initAndShowGUI()
          {
              JFrame f = new JFrame();
              f.setSize(640, 480);
              f.setLocationRelativeTo(null);

              final JFXPanel p = new JFXPanel();
              f.add(p);

              Platform.runLater(new Runnable()
              {
                  @Override
                  public void run()
                  {
                      Group g = new Group();
                      g.getChildren().add(new WebView(new WebEngine("http://www.oracle.com")));
                      Scene s = new Scene(g);
                      p.setScene(s);
                  }
              });

              f.setVisible(true);
          }

          public static void main(String[] args)
          {
              SwingUtilities.invokeLater(new Runnable()
              {
                  @Override
                  public void run()
                  {
                      initAndShowGUI();
                  }
              });
          }
      }


      With the latest LCD text changes (RT-14208), the WebView is completely broken, and the console is full of exceptions:
