JSpinner Value change Events

Question

How to make the update immediately when the jSpinner value was changed.

ChangeListener listener = new ChangeListener() {
  public void stateChanged(ChangeEve         


        

Answer 1

The last answer can be rearranged a little to make it a little more flexible. You can simply use this new MyJSpinner in place of any JSpinner. The biggest change is that you can use this new version with any underlying model of the JSpinner (int, double, byte, etc.)

    public class MyJSpinner extends JSpinner{
        boolean setvalueinprogress=false;
        public MyJSpinner()
        {
            super();
            final JTextField jtf = ((JSpinner.DefaultEditor) getEditor()).getTextField();
            jtf.getDocument().addDocumentListener(new DocumentListener() {              

                    @Override
                    public void removeUpdate(DocumentEvent e) {
                        showChangedValue(e);    
                    }

                    @Override
                    public void insertUpdate(DocumentEvent e) {
                        showChangedValue(e);                
                    }

                    @Override
                    public void changedUpdate(DocumentEvent e) {
                        showChangedValue(e);    
                    }

                    private void showChangedValue(DocumentEvent e){
                        try {
                            if (!setvalueinprogress)
                                MyJSpinner.this.commitEdit();      
                        } catch (NumberFormatException | ParseException ex) {
                                      //handle if you want
                            Exceptions.printStackTrace(ex);
                        }      
                   }
            });
        }

    @Override
    public void setValue(Object value) {
        setvalueinprogress=true;
        super.setValue(value); 
        setvalueinprogress=false;
    }

 }
