In order to be of any use, your dialog (extending JDialog) must have some
controls (like JTextTield). Those have methods which enable you to access the
data they're holding (like getText()). Just "delegate" those methods:
public class MyDialog extends JDialog {
JTextField blahblahField;
...
String getBlahblahText() {
return blahblahField.getText();
}
...
}
//"Parent form" code
...
MyDialog myDialog = ...
...
String blahblahString = myDialog.getBlahblahText();
...
OK?

Here is a simple working example for you. There are literally hundreds
of ways to do this task but these are the critical elements.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class test4 {
static JTextField tf;
static JButton b;
public static void main(String[] args) {
class DataDialog extends JDialog {
public String result;
public DataDialog(Frame parent, boolean modal, String[] data) {
super(parent,modal);
final JComboBox bx = new JComboBox(data);
add(bx,BorderLayout.WEST);
final JButton b = new JButton("OKAY");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
result = (String)bx.getSelectedItem();
setVisible(false);
dispose();
}
});
add(b,BorderLayout.EAST);
pack();
setLocationRelativeTo(parent);
}
}
Runnable r = new Runnable() {
public void run() {
final JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// text field to hold result
tf = new JTextField();
f.add(tf,BorderLayout.NORTH);
b = new JButton("Get Data From DB");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
// disable button so you can't try to retrieve
while
// the previous request is going on
b.setEnabled(false);
// it could take a while so retrieve the data in
// another thread
Runnable r = new Runnable() {
public void run() {
// simulate retrieving data from db
try { Thread.sleep(1000); }
catch (InterruptedException ie) { }
// this is simulated data
String[] s = {"one","two","three","four"};
// create dialog
DataDialog d = new DataDialog(f,true,s);
d.setVisible(true);
// get data from public variable in
DataDialog
// and show data in text field in frame
tf.setText(d.result);
// re-enable button
b.setEnabled(true);
}
};
new Thread(r).start();
}
});
f.add(b,BorderLayout.SOUTH);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
};
EventQueue.invokeLater(r);
}
}
