Tout d'abord, voilà le code précédent décomposé en 3 parties :

package projet;
 
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
 
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
 
 
 
public class SwingListExample extends JPanel {
 
  private BookEntry books[] = {
      new BookEntry(createImageIcon("test.jpg")),
      new BookEntry(createImageIcon("Images\\archi.jpg")),
      new BookEntry(createImageIcon("Images\\eii.jpg")),
      new BookEntry(createImageIcon("Images\\medecine.jpg)),
      new BookEntry(createImageIcon("Images\\psycho.jpg")),
      new BookEntry(createImageIcon("Images\\sciences.jpg")),
      new BookEntry(createImageIcon("Images\\sciencesdulangage.jpg")),
      new BookEntry(createImageIcon("Images\\scienceshumainesetso.jpg")),
      new BookEntry(createImageIcon("Images\\umons.jpg")) };
 
  private JList booklist = new JList(books);
 
  public SwingListExample() {
    setLayout(new BorderLayout());
    JButton button = new JButton("Print");
    button.addActionListener(new PrintListener());
 
    booklist = new JList(books);
    booklist.setCellRenderer(new BookCellRenderer());
    booklist.setVisibleRowCount(4);
    JScrollPane pane = new JScrollPane(booklist);
 
    add(pane, BorderLayout.NORTH);
    add(button, BorderLayout.SOUTH);
 
 
  }
 
  public static void main(String s[]) {
    JFrame frame = new JFrame("List Example");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setContentPane(new SwingListExample());
    frame.pack();
    frame.setVisible(true);
  }
 
    private ImageIcon createImageIcon(String path) {
 
 
        java.net.URL imgURL = getClass().getResource(path);
        if (imgURL != null) {
            return new ImageIcon(imgURL);
        } else {
            System.err.println("Couldn't find file: " + path);
            return null;
        }
    }
 
  // An inner class to respond to clicks on the Print button
  class PrintListener implements ActionListener {
    public void actionPerformed(ActionEvent e) {
      int selected[] = booklist.getSelectedIndices();
      System.out.println("Selected Elements:  ");
 
      for (int i = 0; i < selected.length; i++) {
        BookEntry element = (BookEntry) booklist.getModel()
            .getElementAt(selected[i]);
        System.out.println("  " + element.getTitle());
      }
    }
  }
}

Il y a certainement des trucs à retirer, je n'ai pas besoin du jButton "Print" ni du Listener mais j'ai un peu peur d'enlever des trucs qui sont utiles, donc pour l'instant j'ai rien enlevé tant que ça ne fonctionne pas.

2) La class BookEntry qui reçoit une imageicon et un string même si pour l'instant je n'ai besoin que d'une imageicon (mais plus loin j'aurai besoin des deux)

  public ImageIcon getImage() {

class BookCellRenderer extends JLabel implements ListCellRenderer {
  private static final Color HIGHLIGHT_COLOR = new Color(0, 0, 128);
 
  public BookCellRenderer() {
    setOpaque(true);
    setIconTextGap(12);
  }
 
  public Component getListCellRendererComponent(JList list, Object value,
      int index, boolean isSelected, boolean cellHasFocus) {
    BookEntry entry = (BookEntry) value;
    setText(entry.getTitle());
    setIcon(entry.getImage());
    if (isSelected) {
      setBackground(HIGHLIGHT_COLOR);
      setForeground(Color.white);
    } else {
      setBackground(Color.white);
      setForeground(Color.black);
    }
    return this;
  }
}

Ca se sont mes "outils" on va dire, si je fais tourner SwingListExample ça me crée bien une jList avec images.

Maintenant il y a ce que j'ai déjà fait et je voudrais intégrer une jList d'image là-dedans :

Ma jList concernée c'est jList1. Il faudrait donc que jList1 affiche des images.

Maintenant ce sont les liens entre tout ça que je n'arrive pas à établir. Dois-je passer jList1 en paramètre dans la fonction SwingListExample ?
