How to set the size on a JComboBox

[Aaron Fude]

Hi,

I would like to set the width of a JComboBox to the widest item that
it contains. How does one do that after all the items have been added
to the JComboBox?

Many thanks in advance,

Aaron

<sscce>
import javax.swing.*;

class ComboWidthTest {

public static void main(String[] args) {
String[] items = {
"a",
"b",
"c",
"dddddddddddddddddddddddddddddddddddddd",
"e"
};
JComboBox combo = new JComboBox(items);
JOptionPane.showMessageDialog(null, combo);
}
}

It is usually automatic, unless any of
a number of silly things have been done
by one in the code that one is asking us
to guess about.
