Probleme JPanel

Coucou

Alors voila le probleme, je viens de creer une petite interface graphique grace au GUI de NetBeans et maintenant je suis bien embarasser :

J'ai une classe qui etant JFrame, cette classe possede un JPanel, qui est initialiser par une classe qui etends JPanel. Jusque la ca marche, j'ai bien mon panel dans ma JFrame et tout.

Sur ce panel, j'ai plusieur bouton. Lorsque je clique sur l'un d'eux, je veut faire un appel a une méthode qui etends Jpanel egalement. Je fait donc : -clique sur un bouton
-removeAll pour tout enlever
-ensuite je fait repaint pour mettre a jour
-j'appelle une methode qui me retourne un panel
-je l'ajoute a mon panel
-je fait revalidate pour qu'il prenne en compte les modif
Code:

1 2 3 4 5 6 7 8 9 10 11 public void mouseClicked(MouseEvent e) { if (e.getSource() == jButton6){ // creation de partie this.removeAll(); this.repaint(); Methode m= new Methode (); m.initButton(); this.add(m); this.revalidate(); } }
Amis voila ca marche pas, ca me met un panel vide alors si vous avez une idée parce que la je seche...

Pour commencer, utilises plutot un ActionListener à la place du MouseListener (c'est fait justement pour gérer les évenements de type bouton, liste etc).

Ensuite, difficile de dire où se situe ton problème sans voir un peu plus de code. Comment est fait le panel retourné par Methode() (en particulier en terme de layout, taille, positionnement...)? Quel est le layout de ton panel initial?

as-tu bien ajouté ton écouteur sur ton panel via un addMouseListener ou addActionListener ?

salut

as tu verifier avec des logs que le panel qui est retourné (m?) n'est pas null ou vide ?
si 'this' est ta JFrame il ne faut pas faire
Code:

1 2 this.add(m);
mais
Code:

1 2 this.getContentPane().add(m);

alors en fait J'ai une JFrame qui appel une methode qui etend Jpanel qui elle meme appel JPanel

Voici mes 3 classes
