Change image with JList

[Arkie_student]

Im not good with java and it seems that i cant this working so i give this a try..

What i want is to be able to change image when clicked on the JList i treit it with setIcon() but it didnt work

The

this is the code:

import java.awt.*;
import java.awt.image.*;
import javax.swing.*;
import javax.swing.event.*;

public class CardList extends JFrame
implements ListSelectionListener {

public JLabel l = new JLabel();
public String[] creature = {"AnabaShaman", "BalduvianBarbarians",};


////
//private image[] col = {code here to change image?};
////



public JList list = new JList(creature);
public JScrollPane sp = new JScrollPane(list);
public JLabel image2 = new JLabel(new ImageIcon("c:\\image.jpg"));

public CardList() {
Container c = getContentPane();
c.setLayout (new FlowLayout());
c.add(sp);
c.add(l);
c.add(image2);
l.setForeground(Color.blue);
l.setText("Show card");
l.setPreferredSize(new Dimension(100,75));
list.setVisibleRowCount(3);
list.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
list.addListSelectionListener(this);
pack();
setSize(300,420);
setVisible(true);
setDefaultCloseOperation(EXIT_ON_CLOSE);
}


public void valueChanged(ListSelectionEvent e) {
// l.setForeground(col[list.getSelectedIndex()]);
}

public static void main (String[] arg) {
CardList CL = new CardList ();
}
}

you need to setup an ActionListener for the JList so you know when a listed item is selected.

oops, i told you the wrong thing, sry.
easiest way probably would be like this:

implement the ListSelectionListener class into your JFrame class then create the following method:

public void valueChanged(ListSelectionEvent e)
{
    String name = e.toString();
    if (e == "item 1")
    {}
}

list.addListSelectionListener(this);

Take a look at the ListSelectionEvent class to see the different methods you can use to determine which item you clicked.

[Arkie_student]

part of code:

public String[] creature = {"AnabaShaman", "BalduvianBarbarians",};





//your code
public void valueChanged(ListSelectionEvent e) {

//String name = e.toString();

if (creature.equals ("BalduvianBarbarians")) {
System.out.println("working");
}
else {
System.out.println("not working");
}
}

//Does the event work with array? because i cant figure out why it doesnt //work.
