The JOptionPane in the following sample program is laid out
badly. The dialog box needs to be dragged taller to make the
items lay out correctly. Initially, only the icon is visible. As
the box is made a bit taller, the top of the List Box becomes
visible. As the dialog box is dragged taller still, when the
buttons become visible, it suddenly snaps to the proper layout.


package tests;
import javax.swing.JOptionPane;

public class DialogBug
{
  public DialogBug(String choices[]) {
    String name = (String) JOptionPane.showInputDialog(null,
"Choice",
"Choose a number",
JOptionPane.QUESTION_MESSAGE,
null,
choices,
null);
    System.out.println(name + " chosen");
    System.exit(0);
  }

  public static void main(String args[]) {
    String theList[] = { "One", "Two", "Three", "Four", "Five",
"Six", "Seven", "Eight", "Nine", "Ten",
"Eleven", "twelve", "thirteen", "fourteen",
"fifteen", "sixteen", "seventeen", "eighteen",
"nineteen", "twenty" };
    new DialogBug(theList);
  }
}

a simple JOptionPane.showInputDialog with enough input choices
to cause a JList to be used produces a dialog that is way too
small. not only is the dialog too short (only showing one line
of the JList), but it is also too narrow. if the selected item
requires a horizontal scrollbar, that scroll bar now takes up
the entire visible area of the JScrollPane, and you can't even
see one item from the JList. the following code illustrates
this behaviour. (using default look and feel, metal).
--------------------------------------------------------------
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class OTest extends JFrame
{
    private static final String[] choices =
    {
        "let's start out with a really long string that could mess up",
        "one", "two", "three", "four", "five", "six", "seven", "eight", "nine",
        "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen",
        "seventeen", "eightteen", "nineteen", "twenty",
        "two thousand, three hundred and fifty-two", "2400"
    };

    private JButton open = new JButton("Open dialog");

    public OTest()
    {
        setSize(400, 300);
        setTitle("JOptionPane.showInputDialog Test");
        getContentPane().setLayout(new BorderLayout());
        getContentPane().add(open, BorderLayout.SOUTH);
        open.addActionListener(new ActionListener()
        {
            public void actionPerformed(ActionEvent e)
            {
                String sel = (String) JOptionPane.showInputDialog(OTest.this,
                    "Select an item.",
                    "All items", JOptionPane.PLAIN_MESSAGE,
                     null, choices, choices[0]);

                System.out.println(sel);
            }
        });
    }

    public static void main (String[] args)
    {
        new OTest().setVisible(true);
    }
}

resizing the dialog eventually shows the 10 lines of the JList
specified in the BasicOptionPaneUI, but only after resizing much
larger than is required to show that amount of text.

this seems like a *really* basic problem to have made it through
test. has anyone else seen it? it occurs with Sun 1.1.7, 1.1.8,
JRE 1.2.2, IBM 1.1.7, 1.1.8, and i'm using Swing 1.1.1 full
release.
