Figure 8-2. Metal window adornments for a JFrame

The source to produce Figure 8-2 is shown in Listing 8-1.

Listing 8-1. Setting the Window Decoration Style

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

public class AdornSample {

public static void main(final String args[]) {
Runnable runner = new Runnable() {
public void run() {
JFrame frame = new JFrame("Adornment Example");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setUndecorated(true);
frame.getRootPane().setWindowDecorationStyle(JRootPane.FRAME);
frame.setSize(300, 100);
frame.setVisible(true);
}
};
EventQueue.invokeLater(runner);
}
}

Table 8-2 shows the 12 UIResource -related properties for a JRootPane . Most of these settings have
