JCombobox中添加图片和文本的方法

[world100]

这是我弄出来的在JComobbox中加入图片和文字,但是我不知道怎么才能达到像QQ2009中的那种效果.请大家多指教...
import javax.swing.*;
import java.awt.*;

public class Combobox_image extends JFrame {
JComboBox comb = new JComboBox();
public Combobox_image()

{



for(int i=0;i<5;i++){


LabelCellRender label = new LabelCellRender();
label.setIcon(new ImageIcon("image/3.jpg"));
comb.setRenderer(label);

comb.addItem("label"+i);
}
JPanel p=new JPanel();
p.add(comb);
add(p);
setSize(300, 200);
setLocation(300,300);
setVisible(true);
}

public static void main(String[] args) {
Combobox_image t=new Combobox_image();

}

}
class LabelCellRender extends JLabel implements ListCellRenderer {

public LabelCellRender() {
this.setOpaque(true);
}

public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
if(value!=null)
{
setText(value.toString());
setBackground(isSelected ? Color.darkGray: Color.white);
setForeground(isSelected ? Color.white : Color.black);
}
return this;
}
}
