MouseEvents和图标/ ImageIcon的(MouseEvents and Icon /

请可以监听MouseEvents从图标 / ImageIcon的（API中没有实施任何通知器），未经容器（听JPanel ， JLabel ），或者通过使用转换事件的SwingUtilities ，农具和增加XxxListener到普通的香草Icon / ImageIcon

编辑

类似的代码（@pietblok），但也许不是一个回答我的问题，我不知道如果创建一个图形对象，BufferedImage的和的paintIcon是最后的财产

（我看见几个similair代码，这是SSCCE形式）

不，这是不可能的，必须使用现有的JComponent喜欢的JPanel或JLabel的或实现一个特设的JComponent做你想做什么。
