How to get JList cells to use available space

Question

Hello all!
I have a Swing problem for which I could not find any hints in Swing books or the web.
There is a JList with a custom cell renderer. I'd like to make the cells take all the available space so the JList's area is completely filled with the cells.
This doesn't work, unfortunately. When I resize the frame containing the JList, the cells only get resized horizontally. Their height remains the same so below all cells there is just the JList background.
I did not call JList.setFixedCellHeight or so. Btw, when I put a single custom cell component in a JPanel, it resizes perfectly.
Thanks in advance for any hints!

I did not call JList.setFixedCellHeightWhy not?import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;
import javax.swing.*;
public class ListCellSpace {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new ListCellSpace().makeUI();
    public void makeUI() {
        Object[] data = {"One", "Two", "Three", "Four", "Five", "Six"};
        final JList list = new JList(data);
        list.addComponentListener(new ComponentAdapter() {
            @Override
            public void componentResized(ComponentEvent e) {
                list.setFixedCellHeight(list.getHeight()/list.getModel().getSize());
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(200, 200);
        frame.setLocationRelativeTo(null);
        frame.add(list);
        frame.setVisible(true);
}You do realize that if the JList is sized too small, the item text will be vertically truncated, don't you?
