Pis pour l'appeler j'utilise ceci:
this.setContentPane(new Panneau());
Mais je sais pas ou le mettre, si je met ici:

Code:

---

1 2 3 4

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!
