/差游/你的处理方法在这,JWindow的引用.怎么样?

}

}

else if(event instanceof MouseEvent)

{

MouseEvent me=(MouseEvent)event

if(me.getID()==MouseEvent.MOUSE_RELEASED/*鼠标按下后释放时触发*/)

//好些呢,想监听啥就监听啥

如果你的窗口隐藏了,还喊庆纤想监听,那可能需要JNA库郑仿的支持

这个用MouseListener里的mouseEntered(MouseEvent

e)方法。

鼠标进入区域就产档枯生事件反应。

如果之前申明了点击事件可以在entered时间里呼行模洞码老叫clicked事件。
