Bonjour a tous,

pouvez vous m'indiquer le moyen le plus simple de colorier
une ligne enti�re dans une JTable (Background ou Foreground),
sachant que mon model de JTable extends AbstractTableModel.
Merci d'avance - Alexandre
 

Il faut utiliser un renderer (TableCellRenderer), voila un exemple :

import java.awt.*;

import javax.swing.*;
import javax.swing.table.*;
import javax.swing.table.AbstractTableModel;
public class MyTableModel3 extends AbstractTableModel {

 public MyTableModel3(String[] array) {
   this.array=array;
 }
 public int getColumnCount() {
   return 3;
 }
 public int getRowCount() {
   return array.length;
 }
 public String getColumnName(int column) {
   return columnNames[column];
 }
 public Object getValueAt(int row, int column) {
   switch(column) {
     case 0:
       return array[row];
     case 1:
       return new Integer(array[row].length());
     case 2:
       return new Integer(array[row].indexOf('a'));
   }
   throw new IllegalArgumentException("invalid column 
("+row+','+column+')');
 }

 private String[] array;
 private final static String[] columnNames={
   "Text","Length","Index of 'a'"
 };
 public static void main(String[] args) {
   MyTableModel3 model=new MyTableModel3(args);
  
   final TableCellRenderer renderer=new DefaultTableCellRenderer() {
     public Component getTableCellRendererComponent(JTable table,
       Object value,boolean isSelected,boolean hasFocus,int row,int 
column) {
      
       JLabel label=(JLabel)super.getTableCellRendererComponent(table,
         value,isSelected,hasFocus,row,column);
        
       if (!isSelected)
         label.setBackground((row%2==0)?Color.RED:Color.BLUE);
        
       return label;
     }
   };
  
   JTable table=new JTable(model) {
     public TableCellRenderer getCellRenderer(int row, int column) {
       return renderer;
     }
   };
  
   JScrollPane pane=new JScrollPane(table);
  
   final JFrame frame=new JFrame();
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   frame.setContentPane(pane);
   frame.setSize(400,300);
   frame.show();
 }
}
