title: JSpinner: autoselect onFocus
body: <p>I want to implement autoselect when a user tabs through the JTextFields and JSpinners in my forms. For this I am using this Listener:</p>
  
  <pre><code>public class AutoSelect implements FocusListener {
  
      @Override
      public void focusGained(final FocusEvent e) {
          SwingUtilities.invokeLater(new Runnable() {
              @Override
              public void run() {
                  if (e.getSource() instanceof JTextField) {
                      try {
                          JTextField t = (JTextField) e.getComponent();
                          t.selectAll();
                      } catch (ClassCastException ex) {
                          // 
                      }
                  }else if (e.getSource() instanceof JSpinner){
                      JSpinner spinner = (JSpinner)e.getComponent();
                      JTextField tf = ((JSpinner.DefaultEditor)spinner.getEditor()).getTextField();  
                      tf.selectAll();
                  }
              }
          });
      }
  
      @Override
      public void focusLost(FocusEvent e) {
          // 
      }
  }
  </code></pre>
  
  <p>Only it doesn´t work for my spinners. The event is beeing fired, the correct lines are executed, only nothing happens. I suspect I am not using the .getTextField() correctly. Does anyone have a working solution for this ?</p>
