Bonjour

Je suis débutant et je cherche à afficher une JTable dans un JScrollPane dans une JFrame. Mais cela ne veut pas fonctionner.

Voici mon code (en raccourcis). Tampon_Donnees et Dim_j sont initialisés et ont leurs valeurs dans la procédure Lecture();

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

			Lecture();
 
			Donnees = new Object [6][Dim_j];
 
			for(int j=0;j<Dim_j;j++)
			{
				for(int i=0;i<6;i++)
				{
					Donnees [i][j]= Tampon_Donnees[i][j];
				}
			}
 
			jTable1=new JTable(Donnees,Titres);
 
		    jScrollPane1 = new JScrollPane(jTable1);
		    contentPane.add(jScrollPane1, java.awt.BorderLayout.CENTER);
		    jPanel1.add(essai);
		    contentPane.add(jPanel1, java.awt.BorderLayout.EAST);
		    setJMenuBar(jMenuBar1);
 
		        setDefaultCloseOperation(EXIT_ON_CLOSE);
			setVisible(true);		
 
			jMenuFileNew.setEnabled(false);
 
	  }

Et la réponse de l'exécuteur (ça passe la compilation) vachement explicite (Unknow, Unknow...)

Voici donc mon problème.

Quelqu'un aurait-il une idée ?

Problème résolu

Il suffisait de ne pas utiliser une tableau d'objets pour le constructeur de la JTable, mais un tableau de strings. C'est bizarre puisque le constructeur avec des objets existe, mais il ne marche pas pour moi, j'ai vérifié le tableau et il était bon.

Encore merci
