JOptionPane inputDialog method doesn`t show horizontal scroll bar instead stretch the width of dialog with the largest data in the list

import javax.swing.JFrame;
import javax.swing.JOptionPane;

/**

public class demoDialog
{
  public static final String[] pizzas = { "Cheeseassssssssssss123333331231231232111111111111111111111111111111111111111111111111ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss232222222222222222222222222222222222222222222222222222222222222222222222222222222222224", "Pepperoni", "Sausage", "Veggie","Pepperoni", "Sausage", "Veggie","Pepperoni", "Sausage", "Veggie","Pepperoni", "Sausage", "Veggie","Pepperoni", "Sausage", "Veggie","Pepperoni", "Sausage", "Veggie","Pepperoni", "Sausage", "Veggie","Pepperoni", "Sausage", "Veggie" };

  public static void main(String[] args)
  {
    JFrame frame = new JFrame();
    JOptionPane.showInputDialog(frame, "What's your name?","Title",     JOptionPane.PLAIN_MESSAGE, null, pizzas, null);
    System.exit(0);
  }
}

Above code upon execution shows dialog with no horizontal scroll instead frame stretching w.r.t largest data.

Is there anything we could do to solve this?

Is there anything we could do to solve this

  • Use a JComboBox as the message parameter. The problem with this is, JComboBox will size to it's widest element...
  • Use a JList configured to a single selection. The problem with this is, it's a little confusing from a selection point of view
  • Use a JTable with a JRadioButton in one column. Not much better then the JList, but it provides a slightly better visual cue

List of pizzas 

JList list = new JList(pizzas) {
    @Override
    public Dimension getPreferredScrollableViewportSize() {
        Dimension dim = super.getPreferredScrollableViewportSize();
        dim.width = 25;
        return dim;
    }
};
list.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);

switch (JOptionPane.showOptionDialog(null, new JScrollPane(list), "Pizza", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null, null, 0)) {
    case JOptionPane.OK_OPTION:
        // Get the selected index/item
        break;
}

Don't forget, you could wrap the JList in a JPanel and other components, like a JLabel as prompt
