请教，jPanel中添加鼠标监听问题？？

Question

假如在applet类中有两个jpanel，jpanel1.west存放button，japnel1.center存放jpanel2 希望单击button可以在 jpanel2中绘图 而且图片可以拖动。这个怎么实现呢？？我在button的相应事件里添加了绘图方法，然后创建一个jpanel的内部类负责监听鼠标拖动。为什么监听不到呢？？请帮忙！！！

Answer 1

这个使用JDesktopPane和JInternalFrame可以很方便的实现，而且还能实现多方档。

Answer 2

jPanel1.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                //
            }
        });
