Java Tutorial/2D Graphics/Full Screen

Determine if full-screen mode is supported directly

   <source lang="java">

import java.awt.BorderLayout; import java.awt.Button; import java.awt.Frame; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Window; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; public class Main {

 public static void main(String[] argv) throws Exception {
   GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
   GraphicsDevice gs = ge.getDefaultScreenDevice();
   if (gs.isFullScreenSupported()) {
     // Full-screen mode is supported
   } else {
     // Full-screen mode will be simulated
   }
 }

}</source>

Enter full screen mode

   <source lang="java">

import java.awt.BorderLayout; import java.awt.Button; import java.awt.Frame; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Window; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; public class Main {

 public static void main(String[] argv) throws Exception {
   GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
   GraphicsDevice gs = ge.getDefaultScreenDevice();
   Button btn = new Button("OK");
   btn.addActionListener(new ActionListener() {
     public void actionPerformed(ActionEvent evt) {
       GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
       GraphicsDevice gs = ge.getDefaultScreenDevice();
       gs.setFullScreenWindow(null);
     }
   });
   Frame frame = new Frame(gs.getDefaultConfiguration());
   Window win = new Window(frame);
   win.add(btn, BorderLayout.CENTER);
   try {
     gs.setFullScreenWindow(win);
     win.validate();
   } finally {
     gs.setFullScreenWindow(null);
   }
 }

}</source>

Full screen mode

   <source lang="java">

import java.awt.Frame; import java.awt.Graphics; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Window; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.image.BufferedImage; import java.io.File; import javax.imageio.ImageIO; public class MainClass extends Window {

 private BufferedImage pic;
 public static void main(String[] args) {
   GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
   GraphicsDevice screen = ge.getDefaultScreenDevice();
   if (!screen.isFullScreenSupported()) {
     System.out.println("Full screen mode not supported");
     System.exit(1);
   }
   try {
     BufferedImage loadedpic = ImageIO.read(new File("your.jpg"));
     screen.setFullScreenWindow(new MainClass(loadedpic));
   } catch (Exception e) {
     System.err.println(e.getMessage());
   }
 }
 public MainClass(BufferedImage pic) {
   super(new Frame());
   this.pic = pic;
   addMouseListener(new MouseAdapter() {
     public void mouseClicked(MouseEvent e) {
       System.exit(0);
     }
   });
 }
 public void paint(Graphics g) {
   g.drawImage(pic, 0, 0, getWidth(), getHeight(), this);
 }

}</source>

Leave full-screen mode (Return to normal windowed mode)

   <source lang="java">

import java.awt.BorderLayout; import java.awt.Button; import java.awt.Frame; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Window; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; public class Main {

 public static void main(String[] argv) throws Exception {
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice gs = ge.getDefaultScreenDevice();
    gs.setFullScreenWindow(null);
 }

}</source>
