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

public class Papillon extends JFrame

	  JPanel contentPane;
	  BorderLayout borderLayout1 = new BorderLayout();

	  {
		    contentPane = (JPanel) getContentPane();
		    contentPane.setLayout(borderLayout1);
		    setSize(new Dimension(400, 300));
		    setTitle("Papillon");
		    jMenuFile.setText("Fichier");
		    jMenuFileExit.setText("Quitter");
		    jMenuFileNew.setText("Nouveau");
		    jMenuBar1.add(jMenuFile);
		    jMenuFile.add(jMenuFileExit);
		    jMenuFile.add(jMenuFileNew);
 
			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 ?
