JList is not showing up in my Frame

Question

This is a program I wrote for Having images in a List. A custom cellrenderer and a custom listmodel. Somehow the list itself does not show up in my frame.
import java.awt.Component;
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;
import javax.swing.ListCellRenderer;
public class ListWithImages extends JFrame {
     public ListWithImages() {
          //          We need a Custom model and a Custom Cell Renderer
          CustomImageListModel customImageListModel = new CustomImageListModel();
          CustomImageListCellRenderer customImageListCellRenderer = new CustomImageListCellRenderer();
          JList jlist = new JList(customImageListModel);
          jlist.setCellRenderer(customImageListCellRenderer);
          jlist.setVisibleRowCount(6);
          getContentPane().add(new JScrollPane(jlist));
          pack();
          setVisible(true);
     public static void main(String args[]) {
          new ListWithImages();
     class CustomImageListModel extends DefaultListModel {
          @Override
          public void addElement(Object arg0) {
               // TODO Auto-generated method stub
     //          Add 10 elements with images
               for (int i = 0; i < 10; i++) {
                    super.addElement(new Object[] { "Item " + i, new ImageIcon("smiley.jpg") });
     class CustomImageListCellRenderer extends JLabel implements ListCellRenderer {
          public CustomImageListCellRenderer() {
               setOpaque(true);
          public Component getListCellRendererComponent(JList jlist, Object obj,
                    int index, boolean isSelected, boolean focus) {
               CustomImageListModel model = (CustomImageListModel) jlist.getModel();
               setText((String) ((Object[]) obj)[0]);
               setIcon((Icon) ((Object[]) obj)[1]);
               if (!isSelected) {
                    setBackground(jlist.getBackground());
                    setForeground(jlist.getForeground());
               } else {
                    setBackground(jlist.getSelectionBackground());
                    setForeground(jlist.getSelectionForeground());
               return this;
}

I try yhis code and the list is displayed. Try using a layout to get a better design
public ListWithImages() {
                this.setLaout(new FlowLayout());
          //          We need a Custom model and a Custom Cell Renderer
          CustomImageListModel customImageListModel = new CustomImageListModel();
          CustomImageListCellRenderer customImageListCellRenderer = new CustomImageListCellRenderer();
          JList jlist = new JList(customImageListModel);
          jlist.setCellRenderer(customImageListCellRenderer);
          jlist.setVisibleRowCount(6);
          getContentPane().add(new JScrollPane(jlist));
          pack();
          setVisible(true);
