Text field highlight problem after caret position is set

Question

Hi,
What I am trying to do is: set caret position and then highlight the text after it. The problem is: if I set caret position first, and highlight the rest of the text, the caret position is then set at the end of the entire text; if I highlight text first, and set caret position, then the text is not highlighted.
I am wondering how I can achieve this. Thanks.
The simple test program is below:
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JTextField;
public class TestTextFieldHighlight {
     public static void main(String[] args) {
         JFrame f = new JFrame("Text Field Examples");
         f.getContentPane().setLayout(new FlowLayout());
         JTextField tf = new JTextField("SampleTextField", 20);
         tf.setEditable(true);
         f.getContentPane().add(tf);
         tf.setCaretPosition( 5 );
        tf.setSelectionStart( 6 );
        tf.setSelectionEnd( tf.getText().length() );
        //tf.setCaretPosition( 5 );
         f.pack();
         f.setVisible(true);
}

Answer 1

      //tf.setCaretPosition( 5 );
      tf.setCaretPosition( tf.getDocument().getLength() );
      tf.moveCaretPosition(6);
      //tf.setSelectionStart( 6 );
      //tf.setSelectionEnd( tf.getText().length() );
