I am trying to implement embedded browser in my java Netbeans project so far so good but still the browser is not sophisticated enough to store cookies or any advanced features my goal is basically to be able to access google account and check email or calendar or any similar operation.. can someone please direct me to the right code? thanks in advance.
here is my code:

I am here to ask if it is possible to use JavaFX for the main menu of my game and then switch over to JFrame for the game itself.
The reason I want to do this is because I know how to make pretty fancy game menus in JavaFX and not in JFrame and JavaFX to me also looks alot more fancy then JFrame..
I will truly appreciate any help you give me.
This can be done: you just need to make sure you use the correct threads for everything. In particular, ensure you launch the Swing application on the AWT Event Dispatch Thread.
Here is a simple example.
SwingApp:
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class SwingApp extends JFrame {
public SwingApp() {
setLayout(new BorderLayout());
add(new JLabel("This is the Swing App", JLabel.CENTER), BorderLayout.CENTER);
JButton quitButton = new JButton("Exit");
quitButton.addActionListener(e -> System.exit(0));
add(quitButton, BorderLayout.SOUTH);
setSize(600, 600);
setLocationRelativeTo(null);
setVisible(true);
}
}
and then
import javax.swing.SwingUtilities;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class LaunchSwingFromFX extends Application {
#Override
public void start(Stage primaryStage) {
Platform.setImplicitExit(false);
Button launch = new Button("Launch");
launch.setOnAction(e -> {
SwingUtilities.invokeLater(SwingApp::new);
primaryStage.hide();
});
StackPane root = new StackPane(launch);
Scene scene = new Scene(root, 400, 400);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
How can I embed a custom label I created using JAVAFX into an existing swing's JPanel?
E.g.
Custom JavaFX Label:
public class CustomJavaFXLabel extends Label{
public CustomJavaFXLabel(){
super();
setFont("blah blah blah");
setText("blah blah blah");
/*
*and so on...
*/
}
}
Existing JPanel in swing
public class SwingApp(){
private JPanel jpanel;
public SwingApp(){
jpanel = new JPanel();
jpanel.add(new CustomJavaFXLabel()); //this line does not work
}
}
Error I got is:
The method add(Component) in the type Container is not applicable for argument (CustomJavaFXLabel)
I understand that to for this, I am better off using JLabel to create the custom label. However, due to certain constraints I was required to use FX for the custom Label.
Thanks.
As shown in JavaFX: Interoperability, ยง3 Integrating JavaFX into Swing Applications, add your custom javafx.scene.control.Label to a javafx.embed.swing.JFXPanel. Because a JFXPanel is a java.awt.Container, it can be added to your Swing layout. Several examples may be found here and below.

import java.awt.EventQueue;

import javafx.scene.layout.CornerRadii;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javax.swing.JFrame;
/**

public class LabelTest {
private void display() {
JFrame f = new JFrame("LabelTest");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JFXPanel jfxPanel = new JFXPanel() {
#Override
public Dimension getPreferredSize() {
return new Dimension(320, 240);
}
};
initJFXPanel(jfxPanel);
f.add(jfxPanel);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
private void initJFXPanel(JFXPanel jfxPanel) {
Platform.runLater(() -> {
Label label = new Label(
System.getProperty("os.name") + " v"
+ System.getProperty("os.version") + "; Java v"
+ System.getProperty("java.version"));
label.setBackground(new Background(new BackgroundFill(
Color.ALICEBLUE, CornerRadii.EMPTY, Insets.EMPTY)));
StackPane root = new StackPane();
root.getChildren().add(label);
Scene scene = new Scene(root);
jfxPanel.setScene(scene);
});
}
public static void main(String[] args) {
EventQueue.invokeLater(new LabelTest()::display);

I want to add a java.awt.Panel to my JavaFX8 application. Unfortunately it seems that the Panel doesn't get rendered when attached to a SwingNode.
I have a simple testapplication:
import java.awt.Dimension;
import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.FutureTask;
import java.util.logging.Level;
import java.util.logging.Logger;

import javafx.embed.swing.SwingNode;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class AWTInJFX extends Application {
#Override
public void start(Stage stage) {
final AwtInitializerTask awtInitializerTask = new AwtInitializerTask(() -> {
AWTPanel panel = new AWTPanel();
return panel;
});
SwingNode swingNode = new SwingNode();
SwingUtilities.invokeLater(awtInitializerTask);
try {
swingNode.setContent(awtInitializerTask.get());
} catch (InterruptedException | ExecutionException ex) {
Logger.getLogger(AWTInJFX.class.getName()).log(Level.SEVERE, null, ex);
}
stage.setScene(new Scene(new Group(swingNode), 600, 600));
stage.setResizable(false);
stage.show();
SwingUtilities.invokeLater(() -> {
JFrame frame = new JFrame();
frame.setSize(new Dimension(600, 400));
frame.add(new AWTPanel());
frame.setVisible(true);
});
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
private class AwtInitializerTask extends FutureTask<JPanel> {
public AwtInitializerTask(Callable<JPanel> callable) {
super(callable);
}
}
}
My JPanel containing the java.awt.Panel
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Panel;
import javax.swing.JPanel;
public class AWTPanel extends JPanel{
public AWTPanel()
{
Dimension d = new Dimension(600, 400);
setPreferredSize(d);
Panel p = new Panel();
p.setSize(d);
p.setPreferredSize(d);
p.setBackground(Color.red);
this.add(p);
this.setBackground(Color.green);
}
}
Other AWT components doesn't show up either when I add my AWTPanel to a SwingNode.
Can somebody explain me why this isn't working?
I need a AWT Panel to get a hWnd used in additonal C++ libraries.
From the SwingNode Javadocs:
The hierarchy of components contained in the JComponent instance
should not contain any heavyweight components, otherwise SwingNode may
fail to paint it.
As far as I know, there is no way to embed a heavyweight component, such as an AWT component, in JavaFX.
Depending on your requirements, you could consider reversing things around, so that you have a Swing/AWT frame as your main window, and embed the JavaFX part of your application in a JFXPanel.
I have a simple JavaFX Application that open a Browser and shows google page. After exit the Application and free all objects, I can see that the JavaFX objects like Scene, Stage, WebView and WebEngine are alive in the heap memory after call GC.
I can see this objects with JProfiler and other Profiler tools.
This is my Test code:
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.stage.Stage;
import javax.swing.JButton;
import javax.swing.JFrame;
public class TestMemoryLeak
{
private Stage anotherStage;
private Application app;
public void initFrame()
{
JButton btnStart = new JButton("Start");
ActionListener a1 = new ActionListener() {
public void actionPerformed(ActionEvent e) {
Thread javaFxThread = new Thread(new Runnable() {
#Override
public void run() {
new JFXPanel();
Platform.runLater(new Runnable() {
#Override
public void run() {
try
{
app = MyApplication.class.newInstance();
anotherStage = new Stage();
app.start(anotherStage);
}
catch (Exception e)
{
e.printStackTrace();
}
}
});
}
});
javaFxThread.setDaemon(true);
javaFxThread.start();
}
};
btnStart.addActionListener(a1);
JButton btnStop = new JButton("Stop");
ActionListener a2 = new ActionListener() {
public void actionPerformed(ActionEvent e) {
Platform.runLater(new Runnable() {
public void run() {
try
{
anotherStage.close();
anotherStage = null;
app.stop();
Platform.exit();
}
catch (Exception e)
{
e.printStackTrace();
}
}
});
}
};
btnStop.addActionListener(a2);
JFrame frame = new JFrame();
frame.getContentPane().setLayout(new FlowLayout());
frame.getContentPane().add(btnStart);
frame.getContentPane().add(btnStop);
frame.setTitle("Memory Leak");
frame.setSize(300, 200);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
public static void main(String[] args)
{
new TestMemoryLeak().initFrame();
}
}
And my JavaFX Application:
import javafx.application.Application;
import javafx.geometry.HPos;
import javafx.geometry.VPos;
import javafx.scene.Scene;
import javafx.scene.layout.Region;
import javafx.scene.paint.Color;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class MyApplication extends Application {
private Scene scene;
#Override
public void start(Stage stage)
{
// create the scene
stage.setTitle("Web View");
scene = new Scene(new Browser(), 800, 600, Color.web("#666970"));
stage.setScene(scene);
stage.show();
}
}
class Browser extends Region {
WebView browser = new WebView();
WebEngine engine = browser.getEngine();
public Browser() {
// load the web page
engine.load("http://www.google.es");
//add the web view to the scene
getChildren().add(browser);
}
#Override
protected void layoutChildren() {
double w = getWidth();
double h = getHeight();
layoutInArea(browser,0,0,w,h,0, HPos.CENTER, VPos.CENTER);
}
}
To test the application click on Start Button to show google web page, click on Stop Button to stop the application, run a Profiler tool, and call gc, the JavaFX classes are alive.
I am using java version "1.7.0_51" and windows 8.1
Is there something wrong in my code? Or this is the normal behavior?
Thanks for your responses.
I am working on a swing application using JavaFX controls.
in this application i have three controls buttons WebView and JTable.
on clicking on button1 table should be added on the screen and web view should be removed while on clicking on other button
table should be removed and web view should be added.
I am using the following code.

Put both components in a CardLayout to swap between them. Code using a CardLayout can be seen in this answer.
