这是我的课程内置的示例，效果非常好。我确定我没有正确配置和验证框架，因此请对其进行评论，以便我进行更新。
public class FullScreenExample extends Jframe { public class FullScreen { private GraphicsDevice device; private Jframe frame; private boolean isFullScreen; public FullScreen() { frame = new Jframe(); JPanel content = new JPanel(); content.setLayout(new BorderLayout()); frame.setContentPane(content); frame.setUndecorated(true); // Full screen escape frame.addKeyListener(new KeyListener() { @Override public void keyPressed(KeyEvent e) { // Exit full screen when ESC pressed if (e.getKeyCode() == KeyEvent.VK_ESCAPE) { exitFullScreen(); } } @Override public void keyReleased(KeyEvent e) {} @Override public void keyTyped(KeyEvent e) {} }); } public void enterFullScreen() { if (!isFullScreen) { // Get the current device GraphicsConfiguration config = FullScreenExample.this.getGraphicsConfiguration(); device = config.getDevice(); // Remove the panel from the wrapper myWrapper.remove(myPanel); // Add the panel to the full screen frame frame.getContentPane().add(myPanel); // Set the full screen window device.setFullScreenWindow(frame); isFullScreen = true; } } public void exitFullScreen() { if (isFullScreen) { // Remove the fractal from the full screen frame frame.getContentPane().remove(myPanel); // Add the panel back to the wrapper myWrapper.add(myPanel); // Disable full screen device.setFullScreenWindow(null); // Dispose frame frame.dispose(); // Revalidate window FullScreenExample.this.validate(); isFullScreen = false; } } } private JPanel myPanel, myWrapper; public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { FullScreenExample frame = new FullScreenExample(); frame.init(); frame.setVisible(true); } }); } public void init() { // Generate example main window JPanel content = new JPanel(); content.setBorder(new EmptyBorder(5, 5, 5, 5)); content.setLayout(new BorderLayout()); this.setContentPane(content); this.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); myPanel = new JPanel(); myPanel.setBackground(Color.BLUE); // Full screen button and listener JButton fullscreen = new JButton("Full Screen"); final FullScreen fs = new FullScreen(); fullscreen.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent arg0) { fs.enterFullScreen(); } }); myWrapper = new JPanel(); myWrapper.setLayout(new BorderLayout()); myWrapper.add(myPanel); content.add(myWrapper, BorderLayout.CENTER); content.add(fullscreen, BorderLayout.SOUTH); this.setBounds(100, 100, 350, 350); }}
