How would I make a code/name component?
How would I make a code/name component? I want to either type a code into a component or choose the code from a table. Either way I want the component to display both the code and its corresponding name.
For example, in a bank field, I'd like to type "1234" as a bank code and have the component display both "1234" and "First Bank of Duke". Alternatively, I'd like to choose "1234" from a table, and again have the component display both the code and the name."
I've looked at combo boxes and lists, but both looked too crude to do this.
Thanks,
Matt

is this what you're trying to do?
run the program, then click the "1234" in the list
import javax.swing.*;
import java.awt.*;
import javax.swing.event.*;
class Testing extends JFrame
{
public Testing()
{
setLocation(200,100);
setDefaultCloseOperation(EXIT_ON_CLOSE);
DefaultListModel lm = new DefaultListModel();
final JList list = new JList(lm);
JScrollPane sp = new JScrollPane(list);
sp.setPreferredSize(new Dimension(200,100));
lm.addElement(new Bank("1234","First Bank of Duke"));
JPanel panel1 = new JPanel();
panel1.add(sp);
JPanel panel2 = new JPanel(new GridLayout(1,2));
final JLabel label1 = new JLabel(" ",JLabel.CENTER);
final JLabel label2 = new JLabel(" ",JLabel.CENTER);
panel2.add(label1);
panel2.add(label2);
getContentPane().add(panel1,BorderLayout.CENTER);
getContentPane().add(panel2,BorderLayout.SOUTH);
pack();
list.addListSelectionListener(new ListSelectionListener(){
public void valueChanged(ListSelectionEvent lse){
if(lse.getValueIsAdjusting() == false)
{
Bank bank = (Bank)list.getSelectedValue();
label1.setText(bank.code);
label2.setText(bank.name);
}}});
}
public static void main(String[] args){new Testing().setVisible(true);}
}
class Bank
{
String code;
String name;
public Bank(String c, String n){code = c; name = n;}
public String toString(){return code;}
}
