你好！只需要在按鈕上32313133353236313431303231363533e59b9ee7ad9431333264636163添加鼠標監(jiān)聽器監(jiān)聽鼠標經(jīng)過事件就可以了

核心代碼：

private?void?btnMouseMoved(java.awt.event.MouseEvent?evt)?{

textArea.append("當前鼠標經(jīng)過"+evt.toString()+'\n');

textArea.append("當前鼠標經(jīng)過"+evt.getPoint().toString()+'\n');

}

完整實例：
