## 重量级 在默认的重量级渲染模式下，启用并支持全屏视频。 ## 轻量级 在轻量级渲染模式下，默认情况下禁用全屏功能。要启用它，您必须实现并注册FullScreenHandler，您必须使用适当的Swing或JavaFX功能跟踪全屏进入/退出事件并显示/隐藏全屏窗口。 ``` import com.teamdev.jxbrowser.chromium.Browser; import com.teamdev.jxbrowser.chromium.BrowserType; import com.teamdev.jxbrowser.chromium.FullScreenHandler; import com.teamdev.jxbrowser.chromium.swing.BrowserView; import java.awt.BorderLayout; import java.awt.Frame; import javax.swing.JFrame; import javax.swing.SwingUtilities; import javax.swing.WindowConstants; /** * Demonstrates how to switch between fullscreen mode and window mode. */ public class FullScreenSample { public static void main(String[] args) { Browser browser = new Browser(BrowserType.LIGHTWEIGHT); BrowserView view = new BrowserView(browser); JFrame frame = new JFrame(); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.add(view, BorderLayout.CENTER); frame.setSize(700, 500); frame.setLocationRelativeTo(null); frame.setVisible(true); browser.setFullScreenHandler(new MyFullScreenHandler(frame, view)); browser.loadURL("http://www.quirksmode.org/html5/tests/video.html"); } private static class MyFullScreenHandler implements FullScreenHandler { private final JFrame parentFrame; private final BrowserView view; private final JFrame frame; private MyFullScreenHandler(JFrame parentFrame, BrowserView view) { this.parentFrame = parentFrame; this.view = view; this.frame = createFrame(); } private static JFrame createFrame() { JFrame frame = new JFrame(); frame.setUndecorated(true); frame.setExtendedState(Frame.MAXIMIZED_BOTH); return frame; } @Override public void onFullScreenEnter() { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { parentFrame.getContentPane().remove(view); frame.getContentPane().add(view); frame.setVisible(true); parentFrame.setVisible(false); } }); } @Override public void onFullScreenExit() { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { frame.getContentPane().remove(view); parentFrame.getContentPane().add(view); parentFrame.setVisible(true); frame.setVisible(false); } }); } } } ```
