java version "1.4.0-beta2"

The first call to JWindow.pack() after adding components returns a height
that's one pixel too small.

Call it a second time and you will get the correct size.

awt.Window has the same problem.

The program below shows the problem.

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

public class WindowTest
{
    public static void main(String[] arg)
    {
        JFrame frame = new JFrame("Window Test");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setBounds(100, 100, 400, 300);
        frame.show();

        JButton button = new JButton("A Button");
        System.out.println("Preferred button size: " + button.getPreferredSize());
        JWindow window = new JWindow(frame);
        window.getContentPane().add(button);
        window.pack();
        window.setLocation(200, 200);
        window.show();
        System.out.println("1. Window size: " + window.getSize());
        System.out.println("1. Actuall button size: " + button.getSize());
        System.out.println();
        window.pack();
        System.out.println("2. Window size: " + window.getSize());
        System.out.println("2. Actuall button size: " + button.getSize());
    }
}
