Why JFormattedTextField does not suppport actionPerformed

Question

I have a JFormattedTextField in my form, and i wish that after entering value when user presses enters it should move to next field. But after my all tries I am failed to do so. To achieve this I have attached an ActionListener to JFormattedTextField but pressing of Enter never trigger event. Why? can anybody help?

public class Test extends javax.swing.JFrame {

    /**
     * Creates new form Test
     */
    public Test() {
        initComponents();
    }

    /**
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.

        jLabel1 = new javax.swing.JLabel();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        ftf.setFormatterFactory(new javax.swing.text.DefaultFormatterFactory(new javax.swing.text.NumberFormatter(new java.text.DecimalFormat("#0.00"))));
        ftf.addActionListener(new java.awt.event.ActionListener() {

Answer 1

You need to add an Action:

Action action = new AbstractAction()
{
    @Override
    public void actionPerformed(ActionEvent e)
    {
        //preform your action here.
    }
};


ftf.addActionListener( action );

And the action is executed when enter key is pressed.
