The Applet code:

import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import javax.swing.*;
import javax.swing.event.*;

public class FileTestApplet extends JApplet
{
private JLabel topLabel;
private JLabel bottomLabel;

private JButton errorCausingButton;

public void init()
{
JPanel mainPanel = new JPanel();
mainPanel.setLayout( new BoxLayout( mainPanel, BoxLayout.Y_AXIS
) );
mainPanel.setBorder( BorderFactory.createEtchedBorder() );

topLabel = new JLabel( "This label will not be printed." );

errorCausingButton = new JButton(
"Trying to paint this button while printing causes an
exception." );

bottomLabel = new JLabel( "this label will be printed." );

mainPanel.add( Box.createVerticalGlue() );
mainPanel.add( topLabel );

mainPanel.add( Box.createVerticalStrut( 15 ) );
mainPanel.add( errorCausingButton );

mainPanel.add( Box.createVerticalStrut( 15 ) );
mainPanel.add( bottomLabel );

mainPanel.add( Box.createVerticalGlue() );

this.getContentPane().setLayout(
new BoxLayout( this.getContentPane(), BoxLayout.X_AXIS
) );

this.getContentPane().add( Box.createHorizontalGlue() );
this.getContentPane().add( mainPanel );
this.getContentPane().add( Box.createHorizontalGlue() );
}

}



Additional Info:

In the printout (I wish there was some way to send that along too), the
JButton's text is printed fully while there is no JButton border. The label
added to mainPanel after the JButton is printed, however the text is cut off -
the printed portion is "is label will be printed". The etched border added to
mainPanel prints. This was tested with the AppletViewer and Netscape Navigator
4.7.2. Simply compile and load the Applet. Once it is displayed, print it.
