public class Panneau extends JPanel {
  public void paintComponent(Graphics g){
    //Vous verrez cette phrase chaque fois que la méthode sera invoquée
    System.out.println("Affichage de l'image: 'Quêtes.png' ");
    try {
        Image img = ImageIO.read(new File("Quêtes.png"));
        g.drawImage(img, 7, 31, this);
        //Pour une image de fond
        //g.drawImage(img, 0, 0, this.getWidth(), this.getHeight(), this);
      } catch (IOException e) {
        e.printStackTrace();
      }
  }
}
Pis pour l'appeler j'utilise ceci:
this.setContentPane(new Panneau());
Mais je sais pas ou le mettre, si je met ici:
Code : Sélectionner tout - Visualiser dans une fenêtre à part
1

    public NewJFrame() {
        initComponents();
        this.setContentPane(new Panneau());
    }
Sa m'affiche, mais les composants on disparu!
si je met dans l'événement bouton, sa me bloque tout le programme!

EDIT: Résolu!
J'ai utiliser un JLabel!
