Add JLabel with image to JList to show all the images

Question

Here is my code. It does not show images in the frame and instead shows some text. would anybody please suggest me that what change I should make in the code so that it allows me to show the images in a frame?

import java.awt.Component;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.DefaultListModel;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JList;
import javax.swing.JScrollPane;

public class ListView {


public static void main(String[] args) throws IOException {
    JFrame frame=new JFrame();
    frame.setSize(500,500);
    JLabel lbl[] = new JLabel[10];
    DefaultListModel listModel;
     ImageIcon[] b = new   ImageIcon[10];
    //JList lsm=new JList();
    listModel = new DefaultListModel();
     File folder = new File("C:/Documents and Settings/All Users/Documents/My Pictures/Sample Pictures");
     File[] listOfFiles = folder.listFiles();
      JLabel[] lb=new JLabel[15];
    for (int i = 0; i < listOfFiles.length; i++) 
    {
          System.out.println("chek panth"+listOfFiles[i].getName().toString());
  //      b[i] = ImageIO.read(new File("C:/Documents and Settings/All Users/Documents/My Pictures/Sample Pictures/" + listOfFiles[i].getName().toString()));
         b[i] = new ImageIcon("C:/Documents and Settings/All Users/Documents/My Pictures/Sample Pictures/" + listOfFiles[i].getName().toString());
         lb[i]=new JLabel(b[i]);
         listModel.add(i, lb[i]);

    }
    JList lsm=new JList(listModel);

    Component add = frame.add(new JScrollPane(lsm));

    frame.setVisible(true);

}


}

Note that I would not design the code this way, but I wanted to keep it as close to the original as practical, while making it work to display a list of images on a Windows based box.

import java.awt.*;
import java.awt.image.BufferedImage;
import javax.swing.*;

import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class ListView {

    public static void main(String[] args) throws IOException {
        String path = "C:/Documents and Settings/All Users/Documents/" +
            "My Pictures/Sample Pictures";
        JFrame frame=new JFrame();
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

        File folder = new File(path);
        File[] listOfFiles = folder.listFiles();
        DefaultListModel listModel = new DefaultListModel();
        int count = 0;
        for (int i = 0; i < listOfFiles.length; i++)
        {
            System.out.println("check path"+listOfFiles[i]);
            String name = listOfFiles[i].toString();
            // load only JPEGs
            if ( name.endsWith("jpg") ) {
                ImageIcon ii = new ImageIcon(ImageIO.read(listOfFiles[i]));
                listModel.add(count++, ii);
            }
        }
        JList lsm=new JList(listModel);
        lsm.setVisibleRowCount(1);

        frame.add(new JScrollPane(lsm));

        frame.pack();
        frame.setVisible(true);
    }
}

you can use listcellrenderer to display both image and text in jlist probably like the one below for showing label with icon in list

 public class myRenderer extends DefaultListCellRenderer
{
    @Override
    public Component getListCellRendererComponent(JList list, Object value, int index,boolean isSelected, boolean cellHasFocus) 
    {
        //JLabel l = (JLabel) super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus);
        if(value instanceof JLabel)
        {
            this.setText(((JLabel)value).getText());
            this.setIcon(((JLabel)value).getIcon());
        }
        return this;
    }
}

thanks for trying to be helpful :-) Just: a) you rarely (as in never-ever) have components in a ListModel b) please learn java naming conventions and stick to them – Counterpoint

thats right,but my friend was having trouble adding jlabel with icon to the list so i have to find the solution somehow – Phonsa
