Hi Mr Gregg,
i have tried out the Custom Cell Renderer thing.. but it's seem weird to me..

 
public void getFont() {                          <------------------
Font f = new Font("red", Font.BOLD, 16);
daylist.setFont(f);
}

In my " public void showData() { "

 
if(f.date.equals(da) && f.month.equals(mo) && f.year.equals(ye))  {

setFont(daylist.getFont());                     <---------------

// Display data in TextField or TextArea
dayInput.setText(f.getDate());
monthInput.setText(f.getMonth());
yearInput.setText(f.getYear());
timeInput.setText(f.getTime());
amInput.setText(f.getAm());
appInput.setText(f.getApp());
        
dayInput.requestFocus();

 

D:\Stephenie\School Work\Yr1 Semester 2\Java Project\AppointmentPage.java:200: getFont() in AppointmentPage cannot override getFont() in java.awt.Component; attempting to use incompatible return type
found : void
required: java.awt.Font
public void getFont() {
^

is this correct.. i can't compile becos of the error..? how cum..?

Here's a working example. You should port some of this into your current application to suit your needs.

package com.gthought.swing;
import javax.swing.*;
import java.awt.*;
public class ListTest extends JFrame
{
    public ListTest()
    {
        super("List Test");
        this.setDefaultCloseOperation( JFrame.DISPOSE_ON_CLOSE );
        ListRenderer rend = new ListRenderer();
        DefaultListModel listData = new DefaultListModel();
        listData.addElement( "Gregg" );
        listData.addElement( "Freya" );
        JList list = new JList(listData);
        list.setCellRenderer(rend);
       JScrollPane scroll = new JScrollPane(list);
        this.getContentPane().setLayout( new BorderLayout());
        this.getContentPane().add( scroll );
        this.pack();
        this.setLocationRelativeTo( this );
    }
      public static void main(String[] args)
    {
        new ListTest().setVisible( true );
    }
    class ListRenderer extends DefaultListCellRenderer
    {
        public ListRenderer()
        {
            setOpaque(true);
        }
        public Component getListCellRendererComponent(
                                       JList list,
                                       Object value,
                                       int index,
                                       boolean isSelected,
                                       boolean cellHasFocus)
        {
            Component c = super.getListCellRendererComponent( list, value, index, isSelected, cellHasFocus );
            if (value.toString().equals( "Gregg"))
            {
                this.setForeground( Color.red);
            }
            if (value.toString().equals( "Freya" ))
            {
                this.setForeground( Color.blue);
            }
            return c;
        }
    }
}
