Stop text from wrapping

[Tim Williams]

Forgive me if this is a stupid question, but...
I want to use a JTextPane or JText area to show some text that I will load from a file.
However, I don't want the text to wrap. Instead I want a scrollbar (I don't care if it is shown all the time or not.)
Can anybody help?
Thanks,
Tim.

In a JTextArea, all you have to do is call setLineWrap( false ) on it and stick it in a JScrollPane...

For a JTextPane, you have to override two methods... getScrollableTracksViewportWidth() and
setSize()...

Here's some code that shows how to turn off line wrap in both components...

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
public class TextComparison extends JFrame {
    JTextArea ta;
    JTextPane tp;
 
    public static void main( String[] arg ) {
        new TextComparison();
    }
 
    public TextComparison() {
        ta = new JTextArea();
        tp = new JTextPane() {
            public boolean getScrollableTracksViewportWidth() {
                if( getSize().width < getParent().getSize().width ) {
                    return true;
                }
                else {
                    return false;
                }
            }
 
            public void setSize( Dimension d ) {
                if( d.width < getParent().getSize().width ) {
                    d.width = getParent().getSize().width;
                }
                super.setSize( d );
            }
        };
        String s = "A really, really, long string that should force " +
                "a line wrap out of these text components.  I am doing " +
                "this to show I can disable line wrap in a JTextPane.";
        ta.setText( s );
        tp.setText( s );
        JScrollPane taScroll = new JScrollPane( ta );
        taScroll.setPreferredSize( new Dimension( 150, 150 ) );
        JScrollPane tpScroll = new JScrollPane( tp );
        tpScroll.setPreferredSize( new Dimension( 150, 150 ) );
        getContentPane().add( taScroll, BorderLayout.WEST );
        getContentPane().add( tpScroll,  BorderLayout.EAST );
        setSize( 310, 310 );
        addWindowListener( new WindowAdapter() {
            public void windowClosing( WindowEvent e ) {
                System.exit( 0 );
            }
        } );
        setVisible( true );
    }
}
