JavaFX 2.2 Stage always on top

I know this is a old thread, but things keep on changing. Coming to JDK 8u20 is a new method primaryStage.setAlwaysOnTop(true);

This would be the easiest way to make a stage always on top. For early access to 8u20 visit the website.

public class KeyholeDemo extends Application < @Override public void start(Stage primaryStage) < primaryStage.initStyle(StageStyle.TRANSPARENT); primaryStage.setAlwaysOnTop(true); // code omitted. >public static void main(String[] args) < launch(args); >> 

Sample code taken from this nice writeup

I have a similar problem right now.

I use this line of code to get an always on top effect:

stage.initModality(Modality.APPLICATION_MODAL); 

 Stage stage = (Stage) alert.getDialogPane().getScene().getWindow(); stage.setAlwaysOnTop(true); 

If you want it on top always blocking other windows, just set:

alert.initModality(Modality.APPLICATION_MODAL);

JavaFX Secondary Screen «Always on Top» of All Applications

I suggest not using JDialog and JFXPanel, but only using JavaFX Stages.

Make your secondary screen a Stage and invoke secondaryStage.initOwner(primaryStage) before you show the secondary stage.

From the Stage documentation:

A stage can optionally have an owner Window. When a window is a stage’s owner, it is said to be the parent of that stage . . . A stage will always be on top of its parent window.

I believe setting the owner of the secondary stage, correctly fulfills your requirement of «secondary screen only on top of my application».

Update: answers to additional questions from comments

I don’t want there to be any interaction with the main stage once the secondary is open (the secondary window must be closed to allow interaction again).

To block input to the primary stage, Before showing the secondary stage, call: secondaryStage.initModality(Modality.WINDOW_MODAL).

You could use APPLICATION_MODAL instead of WINDOW_MODAL if you preferred to block all input to any other of your application windows — which one to use depends on the user experience you want.

There’s nothing obvious in the api that would center the secondary screen on the main screen. It just always centers on the monitor, no matter where the main screen is.

This part of the question is a duplicate of Center location of stage. The answer to the duplicate has sample code for performing the centering of the child window.

That’s right, there is nothing in the public api around positioning child windows relative to parent windows. I’ve filed a feature request for this functionality Add helper methods for positioning popups relative to nodes, but the feature request has not yet been implemented as of JavaFX 2.2.

There is a sample project I created to do relative positioning of child dialogs, which might be useful.

Just for centering within the parent, you are probably best off querying the stage location and width before displaying the child and then setting the x and y co-ordinates of the child appropriately when you display it. All of this can be done based on x, y and width properties of windows.

There is also a dialog project in the JavaFX UI controls sandbox which might provides some of the functionality you require so that you don’t need to code it yourself.

In time all of the functionality you are requesting will probably end up in the JavaFX core platform, but I don’t think it’s all quite there yet for JavaFX 2.2.

I agree with jewelsea, but if you need to use JDialog and JavaFX stages (like it was my case), then you can’t set your primaryStage’s parent or modality.

The only solution i found is to use a little «hack»:

I use JNA, Java Native Access API to do my own setAlwaysOnTop() method using User32.INSTANCE.setWindowPos(. ) with HWND_TOPMOST parameter.

Pane always on top

Welcome to StackOverflow! Please be sure to have a little tour on how this site works by navigating to this link.

To achieve the gui design you are looking for, you may want to play with other built-in layout panes of JavaFX. My first suggestion is to use

Second suggestion is to use AnchorPane where the «Menu pane» always snaps to bottom border of the stage.

Thank you for your concern.

I did not used borderpane as node for scene, but I used a simple pane.

I put both big gridpane and menu pane in same initial pane and i used

I also added a colored rectangle on the same coordonates but I assured to add menuPane as childern to initial pane, last one, to be in top of all.

How to set a window always on top of another specific window in javafx

“Always on Top” Windows with Java Guide

If you have ever used an application that has a small window that is always visible above other windows, then you have seen an “Always on Top” window. In this guide, you will learn how to create an “Always on Top” window in Java with code examples.

Creating an “Always on Top” Window

To create an “Always on Top” window in Java, you need to use the `setAlwaysOnTop()` method of the `java.awt.Window` class. The `setAlwaysOnTop()` method takes a boolean value that indicates whether the window should be always on top or not. Here is an example:

import javax.swing.JFrame; public class AlwaysOnTopWindow < public static void main(String[] args) < JFrame frame = new JFrame("Always on Top Window"); frame.setSize(300, 200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLocationRelativeTo(null); // Set the window to always be on top frame.setAlwaysOnTop(true); frame.setVisible(true); >> 

In this example, we create a `JFrame` object and set its size, default close operation, and location. Then we call the `setAlwaysOnTop()` method and pass `true` as the argument to make the window always on top.

Handling Focus Issues

When you create an “Always on Top” window, you may encounter focus issues. For example, when you click on another application, the “Always on Top” window may lose focus and go behind other windows. To handle this issue, you can listen for the `WindowEvent.WINDOW_DEACTIVATED` event and set the window to always be on top again. Here is an example:

import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import javax.swing.JFrame; public class AlwaysOnTopWindow < public static void main(String[] args) < JFrame frame = new JFrame("Always on Top Window"); frame.setSize(300, 200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLocationRelativeTo(null); // Set the window to always be on top frame.setAlwaysOnTop(true); // Listen for the window deactivated event frame.addWindowListener(new WindowAdapter() < @Override public void windowDeactivated(WindowEvent e) < // Set the window to always be on top again frame.setAlwaysOnTop(true); >>); frame.setVisible(true); > > 

In this example, we add a `WindowListener` to the frame and listen for the `windowDeactivated` event. When this event is triggered, we set the window to always be on top again.

Conclusion

Creating an “Always on Top” window in Java is easy with the `setAlwaysOnTop()` method. However, you may encounter focus issues, which you can handle by listening for the `windowDeactivated` event. With this guide and code examples, you can create your own “Always on Top” window in Java.

«Always on Top» Windows with Java

In Java, is there a way to have a window that is «Always on top» regardless if the user switches focus to another application? I’ve searched the web, and all of the solutions lean to some sort of JNI interface with native bindings. Truly this can’t be the only way to do it. or is it?

Java Solutions

Solution 1 — Java

Try this method of the Window class:

It works the same way as the default in the Windows TaskManager: switch to another app but it shows always on top.

This was added in Java 1.5

import javax.swing.JFrame; import javax.swing.JLabel; public class Annoying < public static void main(String[] args) < JFrame frame = new JFrame("Hello!!"); // Set's the window to be "always on top" frame.setAlwaysOnTop( true ); frame.setLocationByPlatform( true ); frame.add( new JLabel(" Isn't this annoying?") ); frame.pack(); frame.setVisible( true ); > > 

_{Window remains on top even when is not active}

Solution 2 — Java

From my observation I found that AlwaysOnTop privilege is given to the latest process which requested to be always on top.

So, if you have an application which setAlwaysOnTop(true) and later another application uses this option, the privilege is given to the second application. In order to work around this I have set the setAlwaysOnTop(false) and again setAlwaysOnTop(true) whenever any window comes on top of the current window.

I’ve checked it with wordweb in windows . WordWeb is one of the applications which uses AlwaysOnTop option from the OS

I’m not sure about if it works properly with your game scenario.

Warning: I’m not aware of the side effects.

import java.awt.event.*; import javax.swing.*; public class MainWindow extends JFrame implements WindowFocusListener < public MainWindow() < addWindowFocusListener(this); setAlwaysOnTop(true); this.setFocusable(true); // this.setFocusableWindowState(true); panel = new JPanel(); //setSize(WIDTH,HEIGHT); setUndecorated(true); setLocation(X,Y); setExtendedState(MAXIMIZED_BOTH); setVisible(true); > public void windowGainedFocus(WindowEvent e)<> public void windowLostFocus(WindowEvent e) < if(e.getNewState()!=e.WINDOW_CLOSED)< //toFront(); //requestFocus(); setAlwaysOnTop(false); setAlwaysOnTop(true); //requestFocusInWindow(); System.out.println("focus lost"); > > private JPanel panel; private static final int WIDTH = 200; private static final int HEIGHT = 200; private static final int X = 100; private static final int Y = 100; public static void main(String args[])< new MainWindow();> > 

Solution 3 — Java

dont use setFullScreenWindow,just get the screen size and then setSize, and everything will be fine.
