Enabling Full-Screen Mode</h3>
In full-screen mode, no window can overlap the full-screen window.
Also, when in full-screen mode, the display mode typically can be
changed if desired (see <a href="../java.awt/screen_SetDispMode.html" class="eglink"><font size="-1"><b>e609</b> Setting the Screen Size, Refresh Rate, or Number of Colors</font></a>).
<pre>
// Determine if full-screen mode is supported directly
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gs = ge.getDefaultScreenDevice();
if (gs.isFullScreenSupported()) {
// Full-screen mode is supported
} else {
// Full-screen mode will be simulated
}
// Create a button that leaves full-screen mode
Button btn = new Button(<font color="#0066ff"><i>"OK"</i></font>);
btn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
// Return to normal windowed mode
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gs = ge.getDefaultScreenDevice();
gs.setFullScreenWindow(null);
}
});
// Create a window for full-screen mode; add a button to leave full-screen mode
Frame frame = new Frame(gs.getDefaultConfiguration());
Window win = new Window(frame);
win.add(btn, BorderLayout.CENTER);
try {
// Enter full-screen mode
gs.setFullScreenWindow(win);
win.validate();
// ...
} finally {
// Exit full-screen mode
gs.setFullScreenWindow(null);
}
