How can I create a Java Swing application that spans the Windows title bar?

Question

I am working on a java swing application that will be used in a psychology experiment, and the researchers asked me to make the program “blacked out” so that there are no external incentives for the user. They want the swing app to be truly full-screen and without any type of headers or minimize / enlarge / close buttons at the top.

The software will run on Windows XP using JavaSE 6.

How can I do this and, if necessary, provide a piece of code.

Thanks!

Answer 1

Use fullscreen Java APIs?

JFrame fr = new JFrame(); fr.setResizable(false); if (!fr.isDisplayable()) { // Can only do this when the frame is not visible fr.setUndecorated(true); } GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice(); try { if (gd.isFullScreenSupported()) { gd.setFullScreenWindow(fr); } else { // Can't run fullscreen, need to bodge around it (setSize to screen size, etc) } fr.setVisible(true); // Your business logic here } finally { gd.setFullScreenWindow(null); } 

Answer 2

Use the setUndecorated(true) property. Please note that this must be done before making the frame visible.

 JFrame frame = new JFrame(); Toolkit tk = Toolkit.getDefaultToolkit(); frame.setBounds(new Rectangle(new Point(0, 0), tk.getScreenSize())); frame.setUndecorated(true); frame.setVisible(true); 

Answer 3

I know this thread is outdated, but I found it while searching for how to do the same myself. I could not find the solutions I wanted to use, so I came up with this. I found that the solution below not only works, but is also much simpler than the answers above.

 JFrame frame = new JFrame(); frame.setResizable(false); frame.setUndecorated(true); Dimension dim = Toolkit.getDefaultToolkit().getScreenSize(); frame.setSize(dim); frame.setVisible(true);
