How to setForeground for individual JTable rows???

Question

How do you set the foreground and background colors for individual rows in a JTable? I don't want every row to change, just the rows I select programmatically (not via the GUI). The JTable.setForeground() from the JComponent base class changes all the rows. Any ideas?

Hi!
Write your own renderer and set it as defaultRenderer on your table. Something like this:
// Using Object.class makes sure the renderer will be used regardless of column class type
myTable.setDefaultRenderer(Object.class, new MyRenderer(Color.red));And the renderer:
class MyRenderer extends javax.swing.table.DefaultTableCellRenderer
    private Color m_mySelectedColor;
    public MyRenderer(Color par_mySelectedColor)
        m_mySelectedColor = par_mySelectedColor;
    public Component getTableCellRendererComponent(JTable table,
                                                   Object value,
                                                   boolean isSelected,
                                                   boolean hasFocus,
                                                   int row,
                                                   int column)
        Component returnComponent = super.getTableCellRendererComponent(
                table,value,isSelected,hasFocus,row,column);
        if (isSelected)
            returnComponent.setBackground(m_mySelectedColor);
        else
            returnComponent.setBackground(table.getBackground());
        return returnComponent;
