Question

First, to make my job explaining a bit easier, here’s some of my code:

JSpinner spin = new JSpinner(); JFormattedTextField text = getTextField(spin);  text.addActionListener(new java.awt.event.ActionListener() {     public void actionPerformed(java.awt.event.ActionEvent evt) {             // Do stuff...     } }); 

…

private JFormattedTextField getTextField(JSpinner spinner) {     JComponent editor = spinner.getEditor();      if (editor instanceof JSpinner.DefaultEditor) {         return ((JSpinner.DefaultEditor )editor).getTextField();     } else {         System.err.println( 'Unexpected editor type: '                            + spinner.getEditor().getClass()                            + ' isn't a descendant of DefaultEditor' );         return null;     } } 

So as you can see, I got that far. And indeed, when I type in a value into the text field component of the spinner (JFormattedTextField), and THEN press ENTER, it works.

What I want now is to be able to have the text field respond to ENTER without having to manually type in a new value (which sorta defeats the purpose of making a spinner out of it). How do I do that?

I know this is not the action listener…but maybe this can work for you?

     text.addKeyListener( new KeyAdapter() {             @Override             public void keyReleased( final KeyEvent e ) {                 if ( e.getKeyCode() == KeyEvent.VK_ENTER ) {                     System.out.println( 'enter pressed' );                 }             }         } );
