[bug-classpath] [Bug swing/23203] New: JList getLastVisibleIndex incorrect

[abalkiss at redhat dot com]

JList getLastVisibleIndex returns -1 if the display area is too big (ie, extra
space at the bottom).

For the testcase below,
expected output: "last vis: 4"
actual output: "last vis: -1"


===TESTCASE===
import javax.swing.*;
import java.io.*;

public class TestList
{
  public static void main (String[] args) throws IOException
  {
    JFrame f = new JFrame();

    DefaultListModel v = new DefaultListModel();
    v.addElement("alsdkfj");
    v.addElement("lasdkfj");
    v.addElement("owieur");
    v.addElement("weoiru");
    v.addElement("lskdfj");

    JList a = new JList(v);
    a.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);

    JScrollPane p = new JScrollPane(a);
    
    f.getContentPane().add(p);
    f.pack();
    f.show();
    System.out.println ("last vis: "+a.getLastVisibleIndex());
  }
}
