Java全屏程序（Swing）-Tab/ALT F4

Question

我需要一种方法来阻止人们在我的Java程序运行时使用其他程序。即阻止人们切换标签，按下ALT + F4 ...

谢谢:)

Answer 1

为了使程序全屏使用;

window.setExtendedState(Frame.MAXIMIZED_BOTH); //maximise window 

window.setUndecorated(true); //remove decorations e.g. x in top right 

并使窗口始终处于最佳使用状态（阻止使用其他正在运行的程序的人员）;

window.setAlwaysOnTop(true); 

Answer 2

您不能在Java级别上做到这一点 - 您需要将操作系统设置为某种“Kiosk模式”。

不请自来的评论 - 你是否需要这个，是因为你（或你的客户）讨厌你的用户，并希望他们永远诅咒你？您是否打算将“关闭计算机”功能添加到您的程序中？

如果您正在寻找全屏支持，这是我使用的代码。应该足以让你走了。您只需要一个全局布尔变量来说明应用程序是否全屏。你可以用它来修补它，让它显示你喜欢的。

 
/** 
    * Method allows changing whether this window is displayed in fullscreen or 
    * windowed mode. 
    * @param fullscreen true = change to fullscreen, 
    *     false = change to windowed 
    */ 
    public void setFullscreen(boolean fullscreen) 
    { 
     //get a reference to the device. 
     GraphicsDevice device = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice(); 
     DisplayMode dispMode = device.getDisplayMode(); 
     //save the old display mode before changing it. 
     dispModeOld = device.getDisplayMode(); 

     if(this.fullscreen != fullscreen) 
     { //are we actually changing modes. 
      //change modes. 
      this.fullscreen = fullscreen; 
      // toggle fullscreen mode 
      if(!fullscreen) 
      { 
       //change to windowed mode. 
       //set the display mode back to the what it was when 
       //the program was launched. 
       device.setDisplayMode(dispModeOld); 
       //hide the frame so we can change it. 
       setVisible(false); 
       //remove the frame from being displayable. 
       dispose(); 
       //put the borders back on the frame. 
       setUndecorated(false); 
       //needed to unset this window as the fullscreen window. 
       device.setFullScreenWindow(null); 
       //recenter window 
       setLocationRelativeTo(null); 
       setResizable(true); 

       //reset the display mode to what it was before 
       //we changed it. 
       setVisible(true); 

      } 
      else 
      { //change to fullscreen. 
       //hide everything 
       setVisible(false); 
       //remove the frame from being displayable. 
       dispose(); 
       //remove borders around the frame 
       setUndecorated(true); 
       //make the window fullscreen. 
       device.setFullScreenWindow(this); 
       //attempt to change the screen resolution. 
       device.setDisplayMode(dispMode); 
       setResizable(false); 
       setAlwaysOnTop(false);

      repaint();
