JScrollpane, scroll to selected element

Question

I have a JList of years inside a JScrollPane. The size of the scrollpane is the height of one row, so you can only see one year at a time. If the selected element in the list is changed, I want the ScrollPane to move to the selected element.
It was suggested to me that I use the methods
scrollRectToVisible()
and
getCellBounds()
but I can't get that to work.
Here is just a rough bit of code using these functions:
import java.awt.*;
import javax.swing.*;
public class test {
     public static void main(String[] args) {
          JList selectYear;
          DefaultListModel selectYearModel;
          JScrollPane selectYearScrollPane;
          selectYearModel = new DefaultListModel();
          selectYear = new JList(selectYearModel);
          selectYear.setFixedCellHeight(25);
          selectYearScrollPane = new JScrollPane(selectYear);
          selectYearScrollPane.setPreferredSize( new Dimension(100, 25) );
          for(int i=1800; i<2200; i++) {
               selectYearModel.addElement(""+i);
          selectYear.setSelectedIndex(5);
          selectYearScrollPane.scrollRectToVisible( selectYear.getCellBounds(selectYear.getSelectedIndex(), selectYear.getSelectedIndex()) );
          JFrame myFrame = new JFrame();
          myFrame.setVisible(true);
          myFrame.add(selectYearScrollPane);
          myFrame.pack();
}If you run this you will see that the selected index is not scrolled to.

Answer 1

I have a JList of years inside a JScrollPane. The
size of the scrollpane is the height of one row, so
you can only see one year at a time.Then you shouldn't use a JList. A JSpinner seems more appropriate.
If the selected
element in the list is changed, I want the ScrollPane
to move to the selected element.
It was suggested to me that I use the methods
scrollRectToVisible()
and
getCellBounds()
ensureIndexIsVisible(int index) might work better.
