JSpinner value change listener

Question

I have a JSpinner with ChangeListener directed. But the ChangeListener is only activated when I press enter or click on one of the JSpinner buttons. I would like to know how to enable ChangeListener when the value is changed.

Answer 1

You need to add a listener to the editor to be notified of any change:

JSpinner.DefaultEditor editor = (JSpinner.DefaultEditor)spinner.getEditor();
JTextField textField = editor.getTextField();
textField.getDocument().addDocumentListener( ... );
