请版主教我怎么重绘popupmenu
右键菜单显示一个图片，上面是我的选项，
不知道怎么实现
这是在桌面显示的一个动态label
右键是这样的，可以看到后面有图片显示，但是被JMenuItem的背景挡住了，而且JMenuItem的背景也没搞好
这是代码
String ico = "UI\\BKIMG.png";
JFrame mini = new JFrame();
MyPanel rootp = new MyPanel();
JLabel beaut = new JLabel(new ImageIcon("UI\\25368_1.gif"));
Point p1_p = new Point(0,0);//用于窗口拖拽
MyPopmenu popm = new MyPopmenu(ico);
MyMenuItem mainp = new MyMenuItem();
JMenuItem restart = new JMenuItem("重启");
JMenuItem dstroy = new JMenuItem("注销");
JMenuItem colse = new JMenuItem("关机");
JMenuItem exit = new JMenuItem("退出");
public void wininit(){
mainp.setStr("张雄");
mainp.setBackImg2("UI\\miniTextA.png");
popm.setPopupSize(55, 225);
popm.setBorderPainted(false);
popm.add(mainp);
popm.addSeparator();
popm.add(restart);popm.addSeparator();
popm.add(dstroy);popm.addSeparator();
popm.add(colse);popm.addSeparator();
popm.add(exit);
rootp.setLayout(null);
rootp.addMouseListener(this);
rootp.addMouseMotionListener(this);
rootp.setSize(40, 40);
beaut.setSize(40, 40);
rootp.add(beaut);
rootp.add(popm);
mini.setContentPane(rootp);
mini.setResizable(false);
mini.setUndecorated(true);
AWTUtilities.setWindowOpaque(mini, false);
mini.setSize(400, 300);
mini.setVisible(true);
}
public class MyPopmenu extends JPopupMenu{
private Image backImg;
public MyPopmenu(String imgPath){
try
{
File f = new File(imgPath);
backImg = ImageIO.read(f);
}
catch (IOException e)
{
e.printStackTrace();
}
}
public MyPopmenu(){
}
public void SetDefulatSize(){
}
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
if(backImg!=null)
g.drawImage(backImg, 0, 0,100,50, null);
}
public Image getBackImg() {
return backImg;
}
public void setBackImg(Image backImg) {
this.backImg = backImg;
this.repaint();
}
public void setBackImg2(String img2Path) {
Image backImg2 = null ;
