如何使用 Java Swing 创建图像映射?

I was thinking of extending JPanel to include an image reference and have that drawn thru the paintComponent(g) method. This part I have done so far, and here's the code:

public class ImagePanel extends JPanel
{
    private static final long serialVersionUID = 1L;

    private Image image;

    public ImagePanel(Image image)
    {
        setImage(image);
    }

    public void setImage(Image newImage)
    {
        image = newImage;
    }

    @Override
    public void paintComponent(Graphics g)
    {
        Dimension size = getSize();
        g.drawImage(image, 0, 0, size.width, size.height, this);
    }

谁能推荐我如何在定义的热点上监听/响应鼠标点击?有人可以另外推荐一种显示弹出窗口的方法吗?我的直觉是扩展 JPopupMenu 让它显示图像，类似于上面的代码.
