给Java的整个程序加上全局快捷键, 而不受限于是哪个组件得到焦点.

只是发来给大家看看的.......谢谢观赏!!!

//给Java的整个程序加上全局快捷键, 而不受限于是哪个组件得到焦点.
Toolkit tk = Toolkit.getDefaultToolkit();

tk.addAWTEventListener(new MyAWTEventListener(), AWTEvent.KEY_EVENT_MASK);


class MyAWTEventListener implements AWTEventListener {

private boolean controlPressed = false;

private boolean cPressed = false;


@Override

public void eventDispatched(AWTEvent event) {

if (event.getClass() == KeyEvent.class) {

// 被处理的事件是键盘事件.

KeyEvent keyEvent = (KeyEvent) event;


if (keyEvent.getID() == KeyEvent.KEY_PRESSED) {

keyPressed(keyEvent);

} else if (keyEvent.getID() == KeyEvent.KEY_RELEASED) {

keyReleased(keyEvent);

}

}

}


private void keyPressed(KeyEvent event) {

if (event.getKeyCode() == KeyEvent.VK_CONTROL) {

controlPressed = true;

} else if (event.getKeyCode() == KeyEvent.VK_C) {

cPressed = true;

}


if (controlPressed && cPressed) {

// 当Ctr + C 被按下时, 进行相应的处理.

System.out.println("Ctr + C");

}

}


private void keyReleased(KeyEvent event) {

if (event.getKeyCode() == KeyEvent.VK_CONTROL) {

controlPressed = false;

} else if (event.getKeyCode() == KeyEvent.VK_C) {

cPressed = false;

}

}

}

可是，在窗体最小化时就不监听了啊，如果窗体隐藏了，还要监听怎么办啊？？
