[kryptonian03]

Good day!

I hava a simple GUI java program built in Netbeans.. I was wondering how could i pass the value of a string to the next frame?

I have attached my code so that you can view my files... Thank you very much!

Good day!

You're learning how to code Swing, so it's probably a mistake for you to let NetBeans create your GUI code for you. I suggest you do it by hand at this stage and then later when you know how Swing works, sure, let NetBeans create some code for you.

This should probably be clarified. The more effort you put into helping us understand your problem the easier we'll be able to help you.

More will look at your code if you post the actual code itself in the forum (with code tags -- please see my link about this below) rather than as an attachment. Another problem with NetBeans is that the code it produces is quite bloated, making it hard for others to read your code -- another reason to code by hand.

Much luck!

OK, I'll be more direct and see if that will help get a response: what information are you trying to pass from one GUI to another?

and as a non-NetBeans GUI example:

import java.awt.Window;
import java.awt.Dialog.ModalityType;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.*;

public class JavaAtmBrief {

   private static void createAndShowUI() {
      JFrame frame = new JFrame("ATM");
      frame.getContentPane().add(new AtmPanel());
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.pack();
      frame.setLocationRelativeTo(null);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      java.awt.EventQueue.invokeLater(new Runnable() {
         public void run() {
            createAndShowUI();
         }
      });
   }
}

class AtmPanel extends JPanel {
   private JTextField acctNumberField = new JTextField(10);
   private JButton okBtn = new JButton("OK");

   public AtmPanel() {
      okBtn.addActionListener(new ActionListener() {
         public void actionPerformed(ActionEvent e) {
            okBtnActionPerformed();
         }
      });
      add(acctNumberField);
      add(okBtn);
   }

   private void okBtnActionPerformed() {
      DialogPanel dialogPanel = new DialogPanel(acctNumberField.getText());

      Window win = SwingUtilities.getWindowAncestor(this);
      JDialog dialog = new JDialog(win, "Dialog", ModalityType.APPLICATION_MODAL);
      dialog.getContentPane().add(dialogPanel);
      dialog.pack();
      dialog.setLocationRelativeTo(null);
      dialog.setVisible(true);
   }
}

class DialogPanel extends JPanel {
   private String acctNumber;

   // gui's constructor accepts a String
   public DialogPanel(String acctNumber) {
      this.acctNumber = acctNumber; // that initializes a field
      add(new JLabel("Account Number: " + acctNumber)); // and is displayed

      add(new JButton(new AbstractAction("Close") {
         @Override
         public void actionPerformed(ActionEvent e) {
            Window win = SwingUtilities.getWindowAncestor(DialogPanel.this);
            win.dispose();
         }
      }));
   }

}
