java+swing全局键盘事件监听问题

[eddie]

各位高手，请教个问题，如何做到swing键盘监听事件，条件是要做到即使焦点不在JFrame上，也要能响应，好比QQ中按CTRL+ALT+Z呼出聊天窗口一样的！不论我当前的窗口是哪里，都可以进行键盘响应！高手们，手头就这80分了，谢啦！

JAVA swing界面JFrame窗体的全局按键事件监听 public class ShowFrame extends JFrame { public void init() { ShowFrame showFrame=new ShowFrame();//首先必须创建好窗体 KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager(); //然后得到当前键盘事件的管理器 manager.addKeyEventPostProcessor((KeyEventPostProcessor)this.getMyKeyEventHandler()); //然后为管理器添加一个新的键盘事件监听者。 } public void getMyKeyEventHandler() { return new KeyEventPostProcessor()//返回一个实现KeyEventPostProcessor接口的匿名内部类。 { public boolean postProcessKeyEvent(KeyEvent e)//实现postProcessKeyEvent方法 { if (e.getKeyCode() == KeyEvent.VK_E)//根据你的需要监听相应的动作。 { /*你想干什么就写在这个地方*/ } } } } 如此以来就完成了。

    KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager();  
     manager.addKeyEventPostProcessor(new KeyEventPostProcessor() {  
        public boolean postProcessKeyEvent(KeyEvent event) {  
            if (event.getID() != KeyEvent.KEY_PRESSED) {  
                return false;  
            }  
            if (curPane != null) {  
                curPane.keyPressed(event);  
                return true;  
            }  
            return false;  
        }  
    });

引用 3 楼 huxiweng 的回复:

    KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager();  
     manager.addKeyEventPostProcessor(new KeyEventPostProcessor() {  
        public boolean postProcessKeyEvent(KeyEvent event) {  
            if (event.getID() != KeyEvent.KEY_PRESSED) {  
                return false;  
            }  
            if (curPane != null) {  
                curPane.keyPressed(event);  
                return true;  
            }  
            return false;  
        }  
    });  

这个在焦点不在的时候不好使啊！
