消除了在Java GUI中使用Alt-F4和Alt-TAB的可能性

消除了在Java GUI中使用Alt-F4和Alt-TAB的可能性

要停止Alt-F4：

yourframe.setDefaultCloseOperation(Jframe.DO_NOTHING_ON_CLOSE);

要停止Alt-Tab，您可以做一些更具侵略性的事情。

public class AltTabStopper implements Runnable{     private boolean working = true;     private Jframe frame;     public AltTabStopper(Jframe frame)     {          this.frame = frame;     }     public void stop()     {          working = false;     }     public static AltTabStopper create(Jframe frame)     {         AltTabStopper stopper = new AltTabStopper(frame);         new Thread(stopper, "Alt-Tab Stopper").start();         return stopper;     }     public void run()     {         try         {  Robot robot = new Robot();  while (working)  {       robot.keyRelease(KeyEvent.VK_ALT);       robot.keyRelease(KeyEvent.VK_TAB);       frame.requestFocus();       try { Thread.sleep(10); } catch(Exception) {}  }         } catch (Exception e) { e.printStackTrace(); System.exit(-1); }     }}
