如何在单个窗口的范围内监听所有键盘事件
我用下面的代码实现了无论焦点在哪个组件上窗口都能监听键盘事件.
public focustest() {//构造方法 ............... Toolkit tk = Toolkit.getDefaultToolkit(); tk.addAWTEventListener(new GlobalEventListener(),AWTEvent.KEY_EVENT_MASK); } class GlobalEventListener implements AWTEventListener {//子类 public void eventDispatched(AWTEvent evt) { if (evt instanceof KeyEvent) { KeyEvent kevt = (KeyEvent) evt; if (kevt.getID() == KeyEvent.KEY_PRESSED) { String modifier = KeyEvent.getKeyModifiersText(kevt.getModifiers()); String key = KeyEvent.getKeyText(kevt.getKeyCode()); System.out.println("Modifier:"+modifier+"|Key:"+key); } } } }
