JavaFX 和 Swing 集成问题

Question

我在 JavaSwing 中创建和应用程序，但后来切换到 JavaFX 并在 JavaFX Maven 项目中添加了所有模块和其他摇摆框架，摇摆的所有组件都在工作，但我想在 Java Swing 中集成一个 FX 框架。场景是这样的，在单击摆动表单的按钮时，我想打开 FXForm。我参考了 stackoverflow 上的所有材料，但没有一个对我有用。

 private void btnViewActionPerformed(java.awt.event.ActionEvent evt) {                                        


        JFrame window = new JFrame();
        SwingUtilities.invokeLater(() -> {
        JFXPanel fXPanel = new JFXPanel();
        Platform.setImplicitExit(false);
        Platform.runLater(() -> {
            try {
                FXMLLoader loader = new 
                FXMLLoader(getClass().getResource("/fxml/ViewScreen.fxml"));
                Parent root = loader.load();
                Scene scene = new Scene(root);
                scene.getStylesheets().add("/styles/Styles.css");
                fXPanel.setScene(scene);
                FXMLController controller = loader.getController();
                controller.initLiveUpdate(mm);
                window.add(fXPanel);
                window.setVisible(true);
                window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                Platform.setImplicitExit(false);
            } catch (IOException ex) {
                Logger.getLogger(ScoreEntry1.class.getName()).log(Level.SEVERE, null, ex);
            }
        });





        }        

以下是例外

我已经尝试过下面的链接，但不适合我 1)How to avoid Not on FX application thread; currentThread = JavaFX Application Thread error?

Answer 1

private void btnViewActionPerformed(java.awt.event.ActionEvent evt) { 
     SwingUtilities.invokeLater(() -> {
            initAndShowGUI();
    });
}
public void initAndShowGUI() {
    // This method is invoked on the EDT thread
    JFrame frame = new JFrame("Swing and JavaFX");
    final JFXPanel fxPanel = new JFXPanel();
    frame.add(fxPanel);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    Platform.runLater(() -> {
        initFX(fxPanel);
    });
}

private void initFX(JFXPanel fxPanel) {
    // This method is invoked on the JavaFX thread
    Scene scene = createScene();
    fxPanel.setScene(scene);
}

private Scene createScene() {
    try {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/ViewScreen.fxml"));
        Parent root = loader.load();
        Scene scene = new Scene(root, Color.ALICEBLUE);
        Stage stage = new Stage();
        stage.setScene(scene);
        return (scene);

    } catch (IOException ex) {
        Logger.getLogger(LoginForm.class.getName()).log(Level.SEVERE, null, ex);
    }
    return null;
}

Answer 2

我认为您有些搞砸了应该由 Platform.runLater() 和 SwingUtilities.invokeLater() 运行的部分。

在 this simple example 中，invokeLater() 初始化 JFXPanel()，后者随后调用 Platform.runLater()，然后它会执行所有 javafx 的工作。

可能会尝试更改在哪种方法中发生的情况并尝试一下。
