带有AWTEventListener的全局事件监听器，以及如何从中提取MouseEvent

只需检查MouseInstance的einstanceof并从MouseEvent中获取所有参数

public void eventDispatched(AWTEvent e) {   if (e instanceof MouseEvent) {    MouseEvent  me=(MouseEvent)e;  } }long KEY_EVENTS = AWTEvent.KEY_EVENT_MASK;long MOUSE_EVENTS = AWTEvent.MOUSE_EVENT_MASK;long MOUSE_MOTION_EVENTS = AWTEvent.MOUSE_MOTION_EVENT_MASK;
