How to add label icon in to our Swing List box

How to add label icon in to our Swing Jlist box

----------------------------------------------------

Steps.

-----

1.create a class(here OnlineUserCellRenderer) and implement ListCellRenderer.

  class OnlineUserCellRenderer extends JLabel implements 

  ListCellRenderer {

        private final Color HIGHLIGHT_COLOR = new Color(0, 0, 128);

        public OnlineUserCellRenderer() {
            setOpaque(true);
            setIconTextGap(12);
        }

        public Component getListCellRendererComponent(JList list, Object value,
                int index, boolean isSelected, boolean cellHasFocus) {
            TestImageList entry = (TestImageList) value;
            setText(entry.getUser());
            if (entry.getImage() != null) {
                setIcon(entry.getImage());
            }
            setIconTextGap(12);
            if (isSelected) {
                setBackground(HIGHLIGHT_COLOR);
                setForeground(Color.white);
            } else {
                setBackground(Color.white);
                setForeground(Color.black);
            }
            return this;
        }
    }

2. Then create a TestImageList class.This class is used to set

   properties for label.

    class TestImageList {

        private final String Name;
        private ImageIcon image;

        public TestImageList(String Name, ImageIcon image) {
            this.Name = Name;
            this.image = image;
        }

        public String getName() {
            return Name;
        }

        public ImageIcon getImage() {
            return image;
        }

        // Override standard toString method to give a useful result
        public String toString() {
            return Name;
        }
    }

3.  Declare DefaultListModel object for inserting data in to jlist

    box in our class import javax.swing.DefaultListModel.and 

    declare a object for DefaultListModel.

   

    public DefaultListModel model = new DefaultListModel();

   

4.  Then add elements in to our DefaultListModel for insert it in

    to swing jList box.

   

    model.add(comboCount, new OnlineUserListEntry(Name, newIcon));
    lstChatlist.setModel(model);
    OnlineUserCellRenderer labelUser = new OnlineUserCellRenderer();
    lstChatlist.setCellRenderer(labelName);
