Run javafx class with gmapsfx library from java swing frame

Question

i want to run the javaFX class (MainApp.java) contains a googlemap using GMapsFX library (http://rterp.github.io/GMapsFX/) from java swing app.

It runs after click on menu item in jframe - executes MainApp.main(args);

The map starts but freezes the rest of the application

How i can run this class to prevent the freeze?

Below it's MainApp.java class

package com.lynden.gmapsexampleapp;

import com.lynden.gmapsfx.GoogleMapView;
import com.lynden.gmapsfx.MapComponentInitializedListener;
import com.lynden.gmapsfx.javascript.object.GoogleMap;
import com.lynden.gmapsfx.javascript.object.LatLong;
import com.lynden.gmapsfx.javascript.object.MapOptions;
import com.lynden.gmapsfx.javascript.object.MapType;
import com.lynden.gmapsfx.javascript.object.Marker;
import com.lynden.gmapsfx.javascript.object.MarkerOptions;
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.scene.Scene;
import javafx.stage.Stage;


public class MainApp extends Application implements MapComponentInitializedListener {

GoogleMapView mapView;
GoogleMap map;

@Override
public void start(Stage stage) throws Exception {

    //Create the JavaFX component and set this as a listener so we know when 
    //the map has been initialized, at which point we can then begin manipulating it.
    mapView = new GoogleMapView();
    mapView.addMapInializedListener(this);

    Scene scene = new Scene(mapView);

    stage.setTitle("JavaFX and Google Maps");
    stage.setScene(scene);
    stage.show();
}


@Override
public void mapInitialized() {
    //Set the initial properties of the map.
    MapOptions mapOptions = new MapOptions();

    mapOptions.center(new LatLong(47.6097, -122.3331))
            .mapType(MapType.ROADMAP)
            .overviewMapControl(false)
            .panControl(false)
            .rotateControl(false)
            .scaleControl(false)
            .streetViewControl(false)
            .zoomControl(false)
            .zoom(12);

    map = mapView.createMap(mapOptions);

    //Add a marker to the map
    MarkerOptions markerOptions = new MarkerOptions();

    markerOptions.position( new LatLong(47.6, -122.3) )
                .visible(Boolean.TRUE)
                .title("My Marker");

    Marker marker = new Marker( markerOptions );

    map.addMarker(marker);

}

public static void main(String[] args) {
    launch(args);
}
}

I have no idea how to nest the whole class in JavaFX thread. I have something like this:

public class NewFXSwingMain extends JApplet {

private static final int JFXPANEL_WIDTH_INT = 300;
private static final int JFXPANEL_HEIGHT_INT = 250;
private static JFXPanel fxContainer;

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {

        @Override
        public void run() {
            try {
                UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
            } catch (Exception e) {
            }

            JFrame frame = new JFrame("JavaFX 2 in Swing");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

            JApplet applet = new NewFXSwingMain();
            applet.init();

            frame.setContentPane(applet.getContentPane());

            frame.pack();
            frame.setLocationRelativeTo(null);
            frame.setVisible(true);

            applet.start();
        }
    });
}

@Override
public void init() {
    fxContainer = new JFXPanel();
    fxContainer.setPreferredSize(new Dimension(JFXPANEL_WIDTH_INT, JFXPANEL_HEIGHT_INT));
    add(fxContainer, BorderLayout.CENTER);
    // create JavaFX scene
    Platform.runLater(new Runnable() {

        @Override
        public void run() {
            createScene();
        }
    });
}

private void createScene() {
    Button btn = new Button();
    btn.setText("Say 'Hello World'");
    btn.setOnAction(new EventHandler<ActionEvent>() {

        @Override
        public void handle(ActionEvent event) {
            System.out.println("Hello World!");
        }
    });
    StackPane root = new StackPane();
    root.getChildren().add(btn);
    fxContainer.setScene(new Scene(root));
}    
}

And now what?

You cannot launch a JavaFX Application from Swing.

The reason is that JavaFX is tightly tied into your system, it uses threads for OpenGL access and includes a lot of native code for performance.

The proper solution is to open a swing window, and embed a JavaFX widget there.

For more details on JavaFX and Swing, see:

http://docs.oracle.com/javase/8/javafx/interoperability-tutorial/swing-fx-interoperability.htm#CHDIEEJE

To embed JavaFX into Swing, use javafx.embed.swing.JFXPanel.

A related example is seen [here](http://stackoverflow.com/a/31576647/230513); also consider a [tag:jmapviewer`] Swing component. – trashgod Aug 12 '15 at 15:36
but i don't know how embed the whole class. it necessary to use this built in methods i mean `public void start(Stage stage)` and `public void mapInitialized()` – kowalptk Aug 12 '15 at 15:54
Still i don't get it how to embed this class – kowalptk Aug 14 '15 at 18:40
locate the line `new Scene()`. Understand what a JavaFX scene is. – Has QUIT--Anony-Mousse Aug 14 '15 at 19:37
Can you type some code for example? NewFXSwingMain must be _extends Application implements MapComponentInitializedListener_ i'm confused how make it works. – kowalptk Aug 14 '15 at 20:09
No, I don't use JavaFX. – Has QUIT--Anony-Mousse Aug 15 '15 at 13:36
