Salut,

La méthode qui nous intéresse est celle-ci :

Code:

---

1 2 3 4 5 6 7

private void bouton_imageActionPerformed(java.awt.event.ActionEvent evt) { JFileChooser chooser =new JFileChooser(); chooser.showOpenDialog(null); File f= chooser.getSelectedFile(); String filename=f.getAbsolutePath(); nom_image.setText(filename); }

---

Alors,

1. Il faut bien entendu charger le fichier image en mémoire pour pouvoir afficher l'image
   
   Tu peux faire ça simplement par :
   
   
   Code:

   ---

   1 2 3 4 5 6 7 8 9

   try { BufferedImage image = ImageIO.read( f );   // ici on peut afficher l'image   } catch(IOException e) { JOptionPane.showMessageDialog(null, "L'image ne peut pas être chargée : ce n'est pas un fichier image ou il est corrompu", "Erreur", JOptionPane.ERROR_MESSAGE); }

   ---

2. Ensuite il faut l'afficher, et, là, çà dépend de comment tu veux l'afficher
   
   1. on peut l'afficher dans un composant de l'interface prévu à cet effet, comme nom_image qui est prévu pour le nom de l'image. D'ailleurs, on pourrait même l'afficher dans le composant qui affiche le nom, éventuellement.
      Il y a pour ce mode, 2 cas possibles :
      
      1. l'image doit s'afficher dans sa taille d'origine, ou une taille fixe proportionnelle à sa taille d'origine
      2. l'image doit s'afficher dans un composant en prenant le maximum de taille qu'on lui donne, et s'adapter à la fenêtre dans laquelle il se trouve : ne jamais dépasser, mais s'afficher le plus grand possible dans cet espace qu'on lui donne
      
      
   2. On peut l'afficher dans un dialogue qui s'ouvre à ce moment-là, ou dans une fenêtre à part (une popup), voire même dans un tooltip qui ne s'afficherait par exemple que lorsqu'on passe la souris sur le nom de l'image
   3. on peut aussi l'afficher dans la JTable si nécessaire
   4. ou n'importe où tu veux, mais il faut que tu nous le précise
   
   

Remarque annexe, au sujet de ton :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

table_enseignant.setModel(new javax.swing.table.DefaultTableModel( new Object [][] { {null, null, null, null, null, null}, {null, null, null, null, null, null}, {null, null, null, null, null, null}, {null, null, null, null, null, null}, {null, null, null, null, null, null},     /*...*/   {null, null, null, null, null, null}, {null, null, null, null, null, null}, {null, null, null, null, null, null}, {null, null, null, null, null, null}, {null, null, null, null, null, null}, {null, null, null, null, null, null} }, new String [] { "Id", "Id_Enseignant", "Nom", "Prenom", "Cours", "Date" } }

---

Je suis admiratif sur l'effort produit pour procéder à 299 "coller", mais tu aurais pu faire simplement :

Code:

---

1 2 3 4 5 6 7

table_enseignant.setModel(new javax.swing.table.DefaultTableModel( new Object [300][6] , new String [] { "Id", "Id_Enseignant", "Nom", "Prenom", "Cours", "Date" } }

---

ça aurait produit le même résultat, plus facilement, de manière plus lisible, et si tu as besoin de changer le nombre de ligne, c'est plus facile de changer le 300 plutôt que de compter les lignes à supprimer, et de refaire des copier/coller... Par ailleurs, il n'est normalement pas indispensable de remplir le tableau de ligne vide : on peut ajouter ou supprimer des lignes dans une JTable, et c'est bien plus simple à gérer.
