Hi there,
is it possible to customize a JList?
I'm creating an IM for a client, and for all the contacts that come on, I would like to be added to a JList. How much customization to the JList can I do? Can I change the font (colour, face and size)? Also, can I change the colour of the 'selected' JList component?
Anything on how to customize a JList would be much appreciated.

Thanks in advance!!

Yes, if practised long before you create the JList.
I did not test it myself, and may be there's more than:

               UIManager.put("List.foreground", new ColorUIResource(int red, int green, int blue);
               UIManager.put("List.background", new ColorUIResource(int red, int green, int blue);
               UIManager.put("List.selectionForeground", new ColorUIResource(int red, int green, int blue);
               UIManager.put("List.selectionBackground", new ColorUIResource(int red, int green, int blue);
               UIManager.put("List.font", new Font(.....));

;JOOP!

Creating your own list cell renderer is the way to go.
That's quite easy:

/*
 * MyListCellRenderer.java
 *
 */

import javax.swing.*;
import java.awt.*;
/**
 *
 * @author  zzynx
 */
public class MyListCellRenderer extends JLabel implements ListCellRenderer {
   
    /** Creates a new instance of MyListCellRenderer */
    public MyListCellRenderer() {
        setOpaque(true);
        setFont(new Font("Verdana", Font.BOLD|Font.ITALIC, 12));       // set your specific font
    }
   
    public java.awt.Component getListCellRendererComponent(JList list,
                Object value, int index, boolean isSelected, boolean cellHasFocus) {

        if  (value != null)
                setText(value.toString());
        setBackground(isSelected ?
                      Color.RED : list.getBackground());     // Selected = RED color
        setForeground(isSelected ?
                      list.getSelectionForeground() : list.getForeground());  // You can adapt the foreground color too
        return this;        
    }
}

In your other code:

      yourJList.setCellRenderer( new MyListCellRenderer() );

Remark: sciuriware's suggestions does also work, but then it is for *ALL* list boxes in your application

There is some good reason to have all your components of certain kind look the same.
It's less confusing to the user. That's why SUN createde the UI properties.
