How to list all properties in the default Toolkit

Question

I would like to know what kinds of properties are stored in the default Toolkit (Toolkit.getDefaultToolkit()). I don't know how to list all of them. Toolkit class has a method getProperty(String key, String defaultValue), but without knowing a list of valid keys, this method is useless.
Any idea would be appreciated.

Here is a little utility that I wrote to display all the UIDefaults that are returned from UIManager.getDefaults(). Perhaps this is what you are looking for?
import javax.swing.*;
import java.util.*;
public class DefaultsTable extends JTable {
    public static void main(String args[]) {
        JTable t = new DefaultsTable();
    public DefaultsTable() {
        super();
        setModel(new MyTableModel());
        JFrame jf = new JFrame("UI Defaults");
        jf.addWindowListener(new WindowCloser());
        jf.getContentPane().add(new JScrollPane(this));
        jf.pack();
        jf.show();
    class MyTableModel extends javax.swing.table.AbstractTableModel {
        UIDefaults uid;
        Vector keys;
        public MyTableModel() {
            uid = UIManager.getDefaults();
            keys = new Vector();
            for (Enumeration e=uid.keys() ; e.hasMoreElements(); ) {
                Object o = e.nextElement();
                if (o instanceof String) {
                    keys.add(o);
            Collections.sort(keys);
        public int getRowCount() {
            return keys.size();
        public int getColumnCount() {
            return 2;
        public String getColumnName(int column) {
            if (column == 0) {
                return "KEY";
            } else {
                return "VALUE";
        public Object getValueAt(int row, int column) {
            Object key = keys.get(row);
            if (column == 0) {
                return key;
            } else {
                return uid.get(key);
    class WindowCloser extends java.awt.event.WindowAdapter {
        public void windowClosing(java.awt.event.WindowEvent we) {
            System.exit(0);
}
