Je ne pense pas que le probème vienne de la car c'est du code qui est généré par netbeans

Ben tu fais comme tu veux :lol:

Mais saches que tu mélanges AWT et SWING...

Visiblement, tu ne comprends pas tout, alors je t'explique :

tu as un constructeur :
Code:

1 2 3 public Imag(JPanel parent) { this.parent=parent; }
... qui prend en paramètre un JPanel (SWING). Et tu lui passes un Panel(AWT) ici :

Code:

Imag img=new Imag(this.pannelImage);

Donc type incompatible, le compilateur ne connait pas de constructeur de Imag qui prenne en paramètre un Panel...

Donc l'erreur vient soit de ton constructeur, soit de la définition de ta variable
pannelImage.

Comme AWT, c'était avant, je t'ai conseillé de garder ton JPanel (SWING c'est maintenant) et de changer tes Panel en JPanel...

Mais bon, il est vrai que si c'est NetBeans qui a généré tout ce code, alors faut surtout rien toucher... (joke :aie: )

Effectivement je savais pas qu'il y avait de Panel et des JPanel 8O, il y a une différence entre les 2 ou c'est la même chose?

Sinon, j'ai modifié mon code, j'ai tout mis en Panel, je n'ai plus d'erreur mais il y a encore un soucis, l'image ne s'affiche pas, j'ai l'impression que paintComponent ne se lance pas, je crois pouirtant que cette méthode est appelé automatiquement par Java,non?

mon code modifié;

Au commencement de Java, il y eu AWT pour faire des interfaces graphique... Ensuite est apparu SWING, une sorte de AWT évolué (qui utilise AWT en interne).

Panel, c'est les panneaux en AWT... JPanel, c'est les panneaux en SWING.

Si tu as le choix entre AWT et SWING (autrement dit, si tu n'es pas forcé de faire du vieux Java), je te conseille vivement d'utiliser SWING. En tout cas, on ne doit pas manipuler des composants AWT et des composants SWING !

Frame c'est du AWT, JFrame, c'est du SWING. Donc soit tu utilises Panel, et alors tu utilises aussi Frame, soit tu utilises JPanel et alors tu utilises aussi JFrame.

Là, tu fais un mixe des 2, il est possible que ce soit la cause de bugs...

Ok, merci beaucoup pour ces petites précisions, j'ai donc suivi tes conseils j'ai tout mis en JPanel, mais malheureusement mon image ne s'affiche toujours pas :roll:

Il faudrait peut être ajouter l'image dans ta fenetre pour qu'elle y apparaisse non ?

Or dans une fenetre, on ne peut y placer que des composants... Donc ta classe Imag doit étendre la classe JComponent, et en effet, la méthode paintComponent sera vue comme une redéfinition de la méthode paintComponent de JComponent...

Tu ajoutes ensuite ton Imag dans ta JFrame (maJFrame.getContentPane().add(monImag) ), et pouf, magie :P

J'ai essayé de suivre ce que tu m'a dit, mais ca ne marche toujours pas, je me suis peut-être planté quelque part ou alors j'ai oublié quelque chose.

Dans la classe Imag, l'attribut parent est inutile. Tu peux le supprimer, et appeler drawImage en mettant le paramètre ImageObserver à null.
De plus, je te conseille de créer l'image dans le constructeur, parce que dans la version actuelle, tu lis le fichier à chaque rafraichissement de l'affichage.

Enfin, j'ai l'impression que tu ne maîtrises pas encore les layouts, donc je te conseille de coder à la main avant d'utiliser des outils de conception de GUI. Je n'ai aucune idée de là ou le GroupLayout a bien pu te placer le composant, avec 6 lignes de contraintes ... :roll: Alors qu'un GridLayout(2, 2) aurait parfaitement fait l'affaire.

Si j'ai bien compris tes conseils, ca donne ca:

        img=new File("Q:\\photos\\Canard1.jpg");
        name=img.getName();
        image=Toolkit.getDefaultToolkit().getImage(name) ;
 
 
 
    }
 
    public void paintComponent(Graphics g) {
 
        g.drawImage(image, 10,10,50,50,null);
 
 
    }}

Mais comment faire pour que l'image s'affiche dans le JPanelImage :roll:

Pour la classe Image, c'est beaucoup mieux. Il ne reste plus qu'à adapter la taille de l'image à celle du composant (si c'est ce que tu veux), en remplaçant 10, 10, 50, 50 par des valeurs calculées en fonction de getWidth() et getHeight().

Pour la fenêtre, il ne reste plus qu'à ajouter l'image à un des JPanels ou au contentPane (comme tu faisais avant), mais je ne connais pas très bien le GroupLayout, et avec du code généré, c'est pas la peine.

Essaie toujours de mettre dans le constructeur :

Code:

jPanelImage.add(img);

mais je ne sais pas si il ne faut pas mettre des paramètres pour le GroupLayout. Et je ne sais pas ou tu veux mettre l'image.
