Re: JScrollPane Scrollbar issues

Mike,

  Thanks for the response. I discovered the problem, however, I'm
looking at a different situation than the simple example below. I'll
modify the ex. below to show you my issue.

 import java.awt.Dimension;
 import javax.swing.*;

 public class Test {

      public static final void main( String args[] ) {
          TestPanel viewport = new TestPanel();
          JScrollPane scrollPane = new JScrollPane( viewport );
          scrollPane.setPreferredSize( new Dimension(300,200) );

          JFrame frame = new JFrame();
          frame.setDefaultCloseOperation( JFrame.DISPOSE_ON_CLOSE );
          frame.setContentPane( scrollPane );
          frame.pack();
          frame.setVisible(true);
     }
 }
// Creates the ViewPort panel
class TestPanel extends JPanel
{
     public TestPanel()
     {
          setLayout(new GridLayout(0, 6));
          for (int i = 0; i < 6; i++)
          {
             // add new repeated panels
                add(new RepeatedPanel());
          }
     }
}
// Repeated panel in grid formation
// ***** PROBLEM: The JTextArea inside the panel is causing
// the JScrollPane to get a different viewing area, because every
// textarea that's added to the parent JScrollPane is messing up the
scrollbar locations

class RepeatedPanel extends JPanel
{
     JTextField singleLine1;
     JTextField singleLine2;
     JTextArea multiLine;

     public TestPanel()
     {
           singleLine1 = new JTextField("single ex. 1");
           add(singleLine1);

           singleLine2 = new JTextField("single ex. 2");
           add(singleLine2);

           multiLine = new JTextArea("multi ex. 1");
           multiLine.setLineWrap(true);
           add(multiLine);
     }
}

Is there a way to hide the inner JTextArea from the outside
JScrollPane, or disable it as a scrollable area? Or would it be
simpler to create a multi-line JTextField with word-wrap
and text aligned with the beginning of the field?

Thanks for your help, it is appreciated.
