Word wrap on scrolling textPane

Question

Hi,
How do I turn the word wrap off on a textPane so I can have a scrollable continuous string?
Thanks
Andy

Having read different posts on this forum I have determined that there are two ways to turn line wrapping off:
1) add the JTextPane to the center of a JPanel using the BorderLayout
2) override the getScrollableTracksViewportWidth() method ot JTextPane. (after testing I determined it was sometimes necessary to also override the setSize() method as well. )
Here is my sample program showing the two approaches.
import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;
public class TestNoWrap extends JFrame
     JTextPane textPane;
     JScrollPane scrollPane;
     public TestNoWrap()
          JPanel panel = new JPanel();
          panel.setLayout( new BorderLayout() );
          setContentPane( panel );
          // no wrap by adding a text pane to a panel first
          textPane = new JTextPane();
          textPane.setText("1234567890 1234567890 1234567890");
          JPanel noWrapPanel = new JPanel();
          noWrapPanel.setLayout( new BorderLayout() );
          noWrapPanel.add( textPane );
          scrollPane = new JScrollPane( noWrapPanel );
          scrollPane.setPreferredSize( new Dimension( 200, 100 ) );
          panel.add( scrollPane, BorderLayout.NORTH );
          // no wrap by overriding text pane methods
          textPane = new JTextPane()
               public void setSize(Dimension d)
                    if (d.width < getParent().getSize().width)
                         d.width = getParent().getSize().width;
                    super.setSize(d);
               public boolean getScrollableTracksViewportWidth()
                    return false;
          textPane.setText("1234567890 1234567890 1234567890");
          scrollPane = new JScrollPane( textPane );
          scrollPane.setPreferredSize( new Dimension( 200, 100 ) );
          panel.add( scrollPane );
     public static void main(String[] args)
          TestNoWrap frame = new TestNoWrap();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setVisible(true);
