KeyListener 问题
KeyListener怎么监听是方向键的啊 就是那四个小箭头
既当按下小箭头时产生相应的事件
public void keyPressed(KeyEvent ev)
{
int keyCode = ev.getKeyCode();
if (keyCode == KeyEvent.VK_LEFT) ....;// your code
else if (keyCode == KeyEvent.VK_RIGHT) ......;// your code
else if (keyCode == KeyEvent.VK_UP) ........;//your code
else if (keyCode == KeyEvent.VK_DOWN) ........;//your code
}
