qu'est-ce que tu entends par "fermer" un JPanel??

élève_ingénieur
j'ai compris que je peux pas fermer un jpanel mais en fait je dois fermer le jframe qui est dedans , c ça???
mon jframe s'appelle frame et mon jpanel s'appelle gestionemplacement, donc , au niveau de l'action de mon bouton visé j'ai écrit :
Code:

1 2 gestionemplacement.frame.dispose();
mais ça marche pas !
merci d'avance

d'un point de vue interface, c'est le panel qui est dans la frame, pas l'inverse. Si tu veux cacher la fenetre, utilise frame.setVisible(false). dispose sert à nettoyer les ressources natives utilisées par une fenetre, ca nécessite que la fenetre ne soit déjà plus visible.

ça marche pas :(
voici mon jpanel

                 frame.setContentPane(new gestionepmlacement());

peut rien dire avec un code aussi succin. Est-ce que frame correspond bien à la fenetre que tu veux cacher? As-tu des erreur dans la console?

non j'ai pas d'erreur, sauf lorsque j'ajoute le code frame.setVisible(false);
voila j'ai commenté les bouts de code que je pense être interessants

il n'y a pas de champ frame dans ta classe étendant JPanel, ta méthode d'action ne peux donc pas savoir dans quelle fenetre tu te trouve. Le mieux est de passer cette frame au constructeur de ta classe et de le stocker dans un champ.

PS: la prochaine fois donne l'erreur, c'est plus rapide que d'essayer de deviner ce qui peux déclencher une erreur dans le code!

oui vous avez raison concernant l'ajout de l'erreur!
veuillez m'excuser! c'est "cannot find symbol"
concernant le code, c'est ce que je dois ajouter au constructeur???
:oops:
Code:

1 2 3 JFrame frame = new JFrame(); frame.setContentPane(new gestionepmlacement());
merci infiniement

passe lui en parametre la JFrame et dans le constructeur même, stocke cette référence à la jframe dans un champ. Ainsi tu pourra y accéder depuis n'importe quelle méthode de ton composant.
Code:

1 2 3 4 5 6 7 8 9 10 public class MonComposant { private JFrame laFrame ; public MonComposant(JFrame laFrame){ this.laFrame=laFrame; } // plus loin public void uneMethodeQuelconque(){ laFrame.setVisible(false); } }
