java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b65)
Java HotSpot(TM) Client VM (build 1.4.0-beta-b65, mixed mode)


The (default) preferred heights of JTextField and JComboBox have been changed
between JDK 1.3 and 1.4 beta. This is a problem because:

    (1) Changing these changes the look of existing screens

    (2) At least for Windows look & feel, JTextField and JComboBox should have exactly the same height.

Here's what happens:

    For Windows look and feel:
        For JDK 1.3: height of JTextField = 21, height of JComboBox = 21
        For JDK 1.4: height of JTextField = 20, height of JComboBox = 24

    For Java look and feel:
        For JDK 1.3: height of JTextField = 21, height of JComboBox = 26
        For JDK 1.4: height of JTextField = 20, height of JComboBox = 29

Note. Relevant bug reports in the database:
4199387 - different height in JDK 1.2.2; fixed in 1.3 -- now broken again
4269430 - 4 added to JComboBox height to fix a different bug -- the culprit?

Test program:

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

public class Test extends JFrame {

    public static void main(String [] args) {

        try {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        } catch (Exception e) {
        }

        final String[] ITEMS = { "First", "Second", "Third" };

        JTextField field = new JTextField("Text Field");
        JComboBox box = new JComboBox();

        Test frame = new Test();
        frame.getContentPane().setLayout(new FlowLayout());
        frame.getContentPane().add(field);
        frame.getContentPane().add(box);

        box.setModel(new DefaultComboBoxModel(ITEMS));

        frame.pack();

        System.out.println("height of JTextField: "
                           + field.getPreferredSize().height);
        System.out.println("height of JComboBox: "
                           + box.getPreferredSize().height);

        frame.setVisible(true);
    }
}
