Setting component focus in JOptionPane.showOptionDialog()

Question

In order to have custom button captions in an input dialog, I created the following code:

String key = null;
JTextField txtKey = new JTextField();        
in

I found a solution ! Very primitive, but works.

Just jump to the field by java.awt.Robot using key "Tab".
I've created utils method calls "pressTab(..)" For example:

GuiUtils.pressTab(1);   <------------- // add this method before popup show

int result = JOptionPane.showConfirmDialog(this, inputs, "Text search window", JOptionPane.PLAIN_MESSAGE);
if (result == JOptionPane.OK_OPTION)
{
    
}

If you should press multiple times on "Tab" to get your Component you can use below method:

GUIUtils.pressTab(3);

Definition:

public static void pressTab(int amountOfClickes)
{
    SwingUtilities.invokeLater(new Runnable()
    {
        public void run()
        {
            try
            {
                Robot robot = new Robot();
                int i = amountOfClickes;
                while (i-- > 0)
                {
                    robot.keyPress(KeyEvent.VK_TAB);
                    robot.delay(100);
                    robot.keyRelease(KeyEvent.VK_TAB);
                }
            }
            catch (AWTException e)
            {
                System.out.println("Failed to use Robot, got exception: " + e.getMessage());
            }
        }
    });
}

If your Component location is dynamic, you can run over the while loop without limitation, but add some focus listener on the component, to stop the loop once arrived to it.
