JavaFX and Swing Integration Issue

Question

I am creating and application in JavaSwing but later on switched to JavaFX and Added all the modules and other swing frame in JavaFX Maven Project all component of swing is working but I want to Integrate one FX Frame in Java Swing. The Scenario is such that on button click of swing form I want to open the FXForm. I refered to all the material here at stackoverflow but non of them is working out for me.

 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);
            }
        });





        }

And Below Is the Exception

I have already tried below link and not working out for me 1) How to avoid Not on FX application thread; currentThread = JavaFX Application Thread error?

Much better now - but just remember: don't expect others to A) read your code to then B) check out for other existing answers to then C) derive what you have read/tried before. — GhostCat, Feb 18 '18 at 12:35
And you want to point out which which lines in your score entry class are listed in that exception trace. That definitely matters. And, **guessing here** - it looks strange that you do use Swing invoke later inside another fx later block. — GhostCat, Feb 18 '18 at 12:37
The Line which are listed in stack trace are below which are point out are FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/ViewScreen.fxml")); and the line Parent root = loader.load(); Scene scene = new Scene(root); — Divyang Mistry, Feb 18 '18 at 12:45
Not in comments, update the question please. And consider deleting no longer required comments, too ;-) — GhostCat, Feb 18 '18 at 12:48
The line you say the stack trace is referencing is not actually the line that's referenced. You have `at com.margosa.frame.ScoreEntry.btnViewActionPerformed(ScoreEntry.java:1121)`, which must be a call to `new Stage()`, because the next line up in the stack trace is the `Stage` constructor. You haven't even posted a call to `new Stage()` in the question: so as your question stands it is unanswerable. — James_D, Feb 18 '18 at 17:11
I have read and refered it and suggested code tell me that you don't need stage when you need to execute it in the swing so I have written it in code — Divyang Mistry, Feb 19 '18 at 14:25

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;
}

This above code work for me the catch is just a small thing you have to set the stage and return scene — Divyang Mistry, Feb 19 '18 at 16:10

I think you somewhat messed up the parts which should be run by Platform.runLater() and SwingUtilities.invokeLater().

In this simple example , the invokeLater() initializes the JFXPanel() which later calls Platform.runLater(), which then does all the javafx stuff.

May try to change what happens in which method and try it out.
