How to make a JFrame really fullscreen?

Question

In my Java application I try to make a JFrame really fullscreen by using this code:

    private static final long se         


        

Answer 1

Use com.apple.eawt.FullScreenUtilities. And make sure to test that the system is running Mac OS.

public void enableFullscreen(Window window, boolean bool) {
    if (System.getProperty("os.name").startsWith("Mac OS")) {
        com.apple.eawt.FullScreenUtilities.setWindowCanFullScreen(window, bool);

    }

}
