public interfaceMouseMotionListenerextendsEventListener 用于在组件上接收鼠标移动事件的侦听器接口。(对于点击和其他鼠标事件,请使用MouseListener) 对处理鼠标运动事件感兴趣的类要么实现此接口(及其包含的所有方法),要么扩展抽象类MouseMotionAdapter(仅覆盖感兴趣的方法)。
You will see a mouse-pressed event, followed by a mouse-exited event, followed by a mouse-released event. You arenotnotified of the cursor's motion. To get mouse-motion events, you need to implement amouse-motion listener. You can find the demo's code inMouseEventDemo.javaandBlankArea....

初学java之MouseMotionListener接口 MouseMotionListener是一个接口,监视组件中鼠标移动事件,MouseMotionAdapter是一个适配器类,它的存在就是为了能够更快速的构造一个侦听器对象,可以通过addMouseMotionListener(new MouseMotionAdapter(){...})向组件中添加一个侦听器。
