Simple popup java form with at least two fields

Question

This is, I suppose, a very simple question for any Java programmer.

My question is as simple as this:

When the user clicks a button, I want to show a popup form that should have at least two JTextFields and two JLabels, so using JOptionPane.showInputDialog is not a possibility.

Thanks.

Answer 1

You should at least consider one of the JOptionPane methods such as showInputDialog() or showMessageDialog().

Addendum: The choice to use JOptionPane hinges more on the suitability of modality, rather than on the number of components shown. See also How to Make Dialogs.

Addendum: As noted in a comment by @camickr, you can set the focus to a particular component using the approach discussed in Dialog Focus.

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

class JOptionPaneTest {

    public static void main(String[] args) {
        String[] items = {"One", "Two", "Three", "Four", "Five"};
        JComboBox combo = new JComboBox(items);
        JTextField field1 = new JTextField("1234.56");
        JTextField field2 = new JTextField("9876.54");
        JPanel panel = new JPanel(new GridLayout(0, 1));
        panel.add(combo);
        panel.add(new JLabel("Field 1:"));
        panel.add(field1);
        panel.add(new JLabel("Field 2:"));
        panel.add(field2);
        int result = JOptionPane.showConfirmDialog(null, panel, "Test",
            JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
        if (result == JOptionPane.OK_OPTION) {
            System.out.println(combo.getSelectedItem()
                + " " + field1.getText()
                + " " + field2.getText());
        } else {
            System.out.println("Cancelled");
        }
    }
}
