Question

当我按下Jbutton时，我需要打开JavaFX窗口。我尝试过各种各样的方式，我在互联网上搜索过，但我什么都没发现。库已正确设置，但无法正常工作。

怎样才能使这个工作？非常感谢！

如果你还没有，你应该通过Integrating JavaFX into Swing Applications。

在您的情况下，您需要使用JFXPanel作为中间节点，它接受JavaFX场景作为其内容并扩展JComponent，这可以帮助您将其设置为JFrame作为组件。

将所有JavaFX内容设置为场景的根目录，然后使用jfxpanel.setScene()将场景添加到此JFXPanel。 您需要在JavaFX应用程序线程上执行此操作，即将其包装在Platform.runLater()。

    public static void main(String[] args)   {
        UTF8 object = new UTF8();
        object.UTF8();
    }

    public void UTF8() {

        JButton browser = new JButton("Click me");

        JFrame frame = new JFrame();
        frame.add(browser);
        frame.setSize(100,100);
        frame.setVisible(true);

        browser.addActionListener(e -> {
            if (e.getSource() == browser) {
                JFXPanel jfxPanel = new JFXPanel();
                Platform.runLater(() -> {
                    initFX(jfxPanel);
                });
                JFrame newFrame = new JFrame();
                newFrame.setSize(300, 200);
                newFrame.setContentPane(jfxPanel);
                newFrame.setVisible(true);
            }
        });
    }

    private static void initFX(JFXPanel fxPanel) {
        // This method is invoked on the JavaFX thread
        TextField addressField;
        WebView webView;
        WebEngine webEngine;
        HBox hBox = new HBox(5);
        hBox.setAlignment(Pos.CENTER);

        //The TextField for entering web addresses.
        addressField = new TextField("Enter Web address here...");
        addressField.setPrefColumnCount(50); //make the field at least 50 columns wide.

        //the engine that manages our pages.
        webEngine = webView.getEngine();
        webEngine.setJavaScriptEnabled(true);
