JTextField Tab Order Changing

[Jeff Grant]

op.setNextFocusableComponent(random);
random.setNextFocusableComponent(op);

setNextFocusableComponent has been deprecated as it overrides the default FocusTraversalPolicy so I would like to avoid using it. However it does get the job done.

The reason I am looking to change the tab order is because the two JTextFields are in a GridLayout but not immediately next to each other. I did some searching and have not found any results.

I do have a KeyListener on these fields and attempted to listen for VK_TAB to then manually set the focus when Tab is pressed, but for some reason the VK_TAB key is not registered as a KeyEvent.

Thanks in advance.

I'm reading this that you want to tab only between 2 components (non-adjacent)

If so, something like this maybe

import javax.swing.*;
import java.awt.*;
class Testing extends JFrame
{
  Object[] focusList;
  int focusNumber = 0;
  public Testing()
  {
    setLocation(400,200);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JPanel jp = new JPanel(new GridLayout(7,1));
    JTextField tf1 = new JTextField(5);
    JTextField op = new JTextField(5);
    JTextField tf3 = new JTextField(5);
    JTextField tf4 = new JTextField(5);
    JTextField tf5 = new JTextField(5);
    JTextField random = new JTextField(5);
    JTextField tf7 = new JTextField(5);
    focusList = new Object[]{op,random};
    jp.add(tf1);
    jp.add(op);
    jp.add(tf3);
    jp.add(tf4);
    jp.add(tf5);
    jp.add(random);
    jp.add(tf7);
    getContentPane().add(jp);
    pack();
    setFocusTraversalPolicy(new MyFocusTraversalPolicy());
  }
  public static void main(String[] args){new Testing().setVisible(true);}
 
  class MyFocusTraversalPolicy extends FocusTraversalPolicy
  {
    public Component getComponentAfter(Container focusCycleRoot,Component aComponent)
    {
      focusNumber = (focusNumber+1) % focusList.length;
      return (JTextField)focusList[focusNumber];
    }
    public Component getComponentBefore(Container focusCycleRoot,Component aComponent)
    {
      focusNumber = (focusList.length+focusNumber-1) % focusList.length;
      return (JTextField)focusList[focusNumber];
    }
    public Component getDefaultComponent(Container focusCycleRoot){return (JTextField)focusList[0];}
    public Component getLastComponent(Container focusCycleRoot){return (JTextField)focusList[focusList.length-1];}
    public Component getFirstComponent(Container focusCycleRoot){return (JTextField)focusList[0];}
  }
}
