Swing can write a desktop program that can be opened as long as jre is installed on the machine. Can we embed web pages in swing?

2. JavaFX mode instance

Embed a JavaFX web browser in Swing

public class Main {
    private static final int WIDTH = Toolkit.getDefaultToolkit().getScreenSize().width;
    private static final int HEIGHT = Toolkit.getDefaultToolkit().getScreenSize().height;
    private static final String url = "http://www.baidu.com";
    private static final String urlStart = "http://";

    /**

     */
    public static void main(String[] args) {
        JFrame frame = new JFrame("Embedded browser");
        final JFXPanel webBrowser = new JFXPanel();
        frame.setLayout(new BorderLayout());
        frame.add(webBrowser, BorderLayout.CENTER);
        Platform.runLater(new Runnable() {

            @Override
            public void run() {
                Group root = new Group();
                Scene scene = new Scene(root, WIDTH, HEIGHT);
                webBrowser.setScene(scene);
                Double widthDouble = new Integer(WIDTH).doubleValue();
                Double heightDouble = new Integer(HEIGHT).doubleValue();

                VBox box = new VBox(10);
                HBox urlBox = new HBox(10);
                final TextField urlTextField = new TextField();
                urlTextField.setText(url);
                Button go = new Button("go");
                urlTextField.setPrefWidth(WIDTH - 80);
                urlBox.getChildren().addAll(urlTextField, go);

                WebView view = new WebView();
                view.setMinSize(widthDouble, heightDouble);
                view.setPrefSize(widthDouble, heightDouble);
                final WebEngine eng = view.getEngine();
                eng.load(url);
                root.getChildren().add(view);

                box.getChildren().add(urlBox);
                box.getChildren().add(view);
                root.getChildren().add(box);

                go.setOnAction(new EventHandler<ActionEvent>() {
                    @Override
                    public void handle(ActionEvent event) {
                        if (!urlTextField.getText().startsWith(urlStart)) {
                            eng.load(urlStart + urlTextField.getText());
                        } else {
                            eng.load(urlTextField.getText());
                        }
                    }
                });
            }
        });

        int screenWidth = Toolkit.getDefaultToolkit().getScreenSize().width;
        int screenHeight = Toolkit.getDefaultToolkit().getScreenSize().height;

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(WIDTH, HEIGHT);
        frame.setLocation((screenWidth - WIDTH) / 2, (screenHeight - HEIGHT) / 2);
        frame.setVisible(true);
    }

}

Three effect

This is a very simple example.

We created JFrame and JFXPanel, then created Scene in Platform.runLater and set it to JFXPanel.

We created a Textfield to enter the URL and a JavaFX Button to jump to the URL. Judge whether the web address starts with http: / /, and do simple processing.

Here's how it works:
