Select part of jtextarea content over a button click

Question

Hi,
i would like to do something quite simple, but i don't manage to do it and don't understand why my code doesn't work :s
Actually, i would like to select a part of the text contained in a jtextarea when the user clicks over a jbutton ; here is my code:
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextArea;
public class BasicFrame extends JFrame implements ActionListener {
     private static final long serialVersionUID = 1L;
     private JTextArea jta;
     private JButton b;
     public BasicFrame() {
          this.setSize(400,400);
          this.getContentPane().setLayout(new GridLayout(2,1));
          this.getContentPane().add(this.jta = new JTextArea());
          this.getContentPane().add(this.b = new JButton("foo"));
          this.b.addActionListener(this);
          this.setVisible(true);
          this.setDefaultCloseOperation(EXIT_ON_CLOSE);
          this.setLocationRelativeTo(null);
     @Override
     public void actionPerformed(ActionEvent arg0) {
     //     this.jta.select(2, 5);
          this.jta.setCaretPosition(2);
          this.jta.moveCaretPosition(5);
     public static void main(String [] args) {
          BasicFrame bs = new BasicFrame();
          bs.jta.setText("this crap won t work");
}notice that this solution doesn't work, but if the "select" (or setcaret+movecaret) instruction is put directly in the main, it will work
Suggestions? Advices? Answers?
Thanks in advance!

Answer 1

the code does work, problem is the textArea needs the focus to show the highlighted (selected) text,
but when you click the button, focus goes to the button.
run the code then tab (not click) to the textArea, you will see the text selected
simple fix is to add this line at the end of the constructor
b.setFocusable(false);
