Re: Combobox how to disable edit but allow select

a) Why do you want to extend JComboBox? In most (99.9 %) cases you don't
need to. You can just _use_ it.

b) the problem is neither JComboBox nor the mentioned "line A".

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

public class Test {

     static class MyComboBox extends JComboBox
             implements ActionListener {
         public void actionPerformed( ActionEvent e ) {
             System.out.println( "Action" );
         }

         public MyComboBox() {
             addItem("a");
             addItem("b");
             addItem("c");
             setEditable( false );
             addActionListener( this );
         }
     }

     public static final void main( String args[] ) throws Exception {
         JFrame frame = new JFrame("Test");
         frame.setDefaultCloseOperation( JFrame.DISPOSE_ON_CLOSE );
         frame.setContentPane( new MyComboBox() );
         frame.pack();
         frame.setVisible( true );
     }
}

c) If it really doesn't work when line A is present then I'd guess the
problem's in your action listener.

d) Next time please post an SSCCE [1] - otherwise we'll move in a circle.
