Bonjour,
j'essaye d'afficher une Jtable dans une interface graphique.
j'utilise:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

   JFrame frame = new JFrame();
    ImageIcon Applicon = new ImageIcon(jar.getResource("icons/iconAppli.gif"));
    frame.setIconImage(Applicon.getImage());
 
   JDialog dialog = new JDialog(frame);
 
   dialog.setContentPane(getPrivateCleaningTable());
   dialog.pack();
 
   Toolkit tk = Toolkit.getDefaultToolkit();
   Dimension screenSize = tk.getScreenSize();
 
    dialog.setBounds(screenSize.width*5/100,screenSize.height*5/100,screenSize.width*90/100,screenSize.height*90/100);// center
 
   dialog.setTitle(this.getFullApplicationName()+" (secondary)");  
   dialog.show();

qui renvoie à :

JTable cleanTable = new JTable(DCMParser.getPrivateCleanList(), DCMParser.getPrivateColumnNames());// get Table data Object
 
 
   javax.swing.table.DefaultTableCellRenderer dtcr = new javax.swing.table.DefaultTableCellRenderer();
   dtcr.setHorizontalAlignment(SwingConstants.CENTER);
 
   for(int x=0;x<cleanTable.getColumnModel().getColumnCount();x++)// center all excepted 1
               if(x!=1)cleanTable.getColumnModel().getColumn(x).setCellRenderer(dtcr);
 
    cleanTable.getColumnModel().getColumn(1).setPreferredWidth(250);
 
    cleanTable.setGridColor(new Color(220,220,225));
 
    TableCellRenderer rendererFromHeader = cleanTable.getTableHeader().getDefaultRenderer();
    JLabel headerLabel = (JLabel)rendererFromHeader;
    headerLabel.setHorizontalAlignment(JLabel.CENTER);
    cleanTable.getTableHeader().setFont(new Font("Tahoma", Font.BOLD, 11));

et à chaque tentative d'affichage, j'obtiens un message d'erreur du type:

(le indexoutofbounds varie parfois).

J'ai changé le tableau manuellement par quelque chose de très simple
(A B C D E en titre, et 1 2 3 4 5 sur chaque ligne...) pour être sur que l'erreur ne venait pas de mon tableau, et j'ai toujours la même erreur...
quelqu'un aurait une idée pour m'aider?
merci d'avance!
