JOptionPane buttons

[Jennifer Sohl]

I have a JOptionPane that contains a JPanel which has a text field on it.
When the user hits enter after they key into the text field, it should pull up some db info. However, when they hit enter, the option pane closes, rather than staying up. How can I tell my JOptionPane not to close unless the user actually pressed the OK button or closed the dialog ('X') with their mouse?

Thanks in advance!

When the JOptionPane showXXX method returns the dialog closes. You can open another one each time you get input and want to continue (shown below). Or, instead of using JOptionPane you could make a JDialog with your components and control it from within your event code.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
public class OptionTest
{
    public static void main(String[] args)
    {
        final JFrame f = new JFrame();
        JButton show = new JButton("show dialog");
        show.addActionListener(new ActionListener()
        {
            public void actionPerformed(ActionEvent e)
            {
                showDialog(f);
            }
        });
        JPanel panel = new JPanel();
        panel.add(show);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(panel);
        f.setSize(200,140);
        f.setLocation(200,200);
        f.setVisible(true);
    }
 
    private static void showDialog(Component c)
    {
        String retVal = (String)JOptionPane.showInputDialog(c,
                                            "enter some text and press enter",
                                            "this is a test",
                                            JOptionPane.PLAIN_MESSAGE,
                                            null,
                                            null,
                                            "");
        if(retVal == null || retVal.equals(""))
            System.out.println("all done with this JOptionPane");
        else if(!retVal.equals(""))
        {
            System.out.println("retVal = " + retVal);
            showDialog(c);
        }
    }
}
