JComboBox??

[comp101]

Having recently found and implemented JComboBox in my code, I cant seem to find anywhere that will help me with the action or itemlistener. What I want to do is set certain TextFields to "uneditable" if "NO" in my drop down menu in my ComboBox is selected...and editable if "YES" in the ComboBox is selected. I dont know if to use itemlisteneres or actionlisteners. Ive tried both and failed miserablly both times. Can someone help?

Here is the specific part of the code:

String [] pp = {"NO", "YES"};
jcbppayment = new JComboBox(pp);
jcbppayment.addItemListener(this);
jcbppayment.addActionListener(this);

jtfamount = new JTextField();
jtfswpayment = new JTextField();
jtfamount.setEditable(false);
jtfswpayment.setEditable(false);

...


public void actionPerformed(ActionEvent e) {
}

...

public void itemStateChanged(ItemEvent ie){
}

Here's a quick example of handling a performed action.

Make sure to read through java tutorials before posting questions because lots of questions will probably already be answered:
http://java.sun.com/docs/books/tutor.../combobox.html

public class ComboDemo extends JPanel implements ActionListener{
    public ComboDemo(){
        String[] yesNo= {"YES","NO!"};
        JComboBox comboBox = new JComboBox(yesNo);
        comboBox.addActionListener(this);

        add(comboBox);
    }
    public void actionPerformed(ActionEvent evt){
        String selected;
        JComboBox c = (JComboBox)evt.getSource();
        selected = (String)c.getSelectedItem();
        System.out.println("You selected: "+selected);
    }
    public static void createAndShowGUI(){
        JFrame myFrame = new JFrame();
        JPanel panel = new ComboDemo();
        myFrame.add(panel);
        myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        myFrame.setSize(200, 100);
        myFrame.setVisible(true);

    }
    public static void main(String args[]) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

Then you will change your components in the actionPerformed function based on the selected item.
eg. myComponent.setEditable(false);

Good luck
