So basically im writing a popup button box in java. I have everything working except i need somehow for the class to wait until a button is pressed to return a boolean value back to the program. Any Ideas?

ActionListener

And doesn't Java already have some sort of a popup thingy? Or am I completely misunderstanding what you're trying to do?

Well maybe, but I cant find one that I like. I dont know how to use the wait method i keep getting a runtime error of current thread not owner.

here is my current code

import javax.swing.AbstractButton;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
public class ButtonDemo extends JPanel
                        implements ActionListener {
  private boolean actionDone=false;
  protected JButton b1, b2, b3;
  private  static JFrame frame2 =null;
    
  public ButtonDemo() {
        b1 = new JButton("Yes");
        b1.setVerticalTextPosition(AbstractButton.BOTTOM);
        b1.setHorizontalTextPosition(AbstractButton.LEFT); 
        b1.setMnemonic(KeyEvent.VK_D);
        b1.setActionCommand("Yes");
        b2 = new JButton("No");
        b2.setVerticalTextPosition(AbstractButton.BOTTOM);
        b2.setHorizontalTextPosition(AbstractButton.CENTER);
        b2.setMnemonic(KeyEvent.VK_M);
        b2.setActionCommand("No");
        b1.addActionListener(this);
        b2.addActionListener(this);
   JPanel panel1 = new JPanel(); 
     JPanel panel2 = new JPanel();
     String message="Yes or no?";
     
      JLabel label = new JLabel(message);
        panel1.add(label);
        add(panel1);
       panel2.add(b1);
        panel2.add(b2);
       add(panel2);
            
    }
    public synchronized void actionPerformed(ActionEvent e) {
  System.out.println(e.getActionCommand());
  
      if ("Yes".equals(e.getActionCommand())) {
              actionDone=true;
              notifyAll();
        } 
      else if("No".equals(e.getActionCommand())) {
               actionDone=true;
                notifyAll();
        }
    }
  private boolean actionDone()
  {return actionDone();}
    private static void createAndShowGUI() {
        JFrame.setDefaultLookAndFeelDecorated(true);
        JFrame frame = new JFrame();
        frame2=frame;
        frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
        ButtonDemo newContentPane = new ButtonDemo();
        newContentPane.setOpaque(true); 
        frame.setContentPane(newContentPane);
       
        frame.pack();         
        frame.setVisible(true);
    }

    public synchronized void  buttonInput() {
               createAndShowGUI(); 
            
                    try {
            wait();
        } catch (InterruptedException e) { }
    
    System.out.println("Here");
    }                  
    public static void main(String args[])
    {
      ButtonDemo b=new ButtonDemo();
     b.runMe();}
    public void runMe()
    { buttonInput();}
} 

Basically what I want in place of the button input method would have it return a boolean at the end after a button is pressed. When creating this I was trying to make it completly encapsulated so that all i would do it call buttonInput and have it return a boolean true for yes and false for no.

o/~ If you're happy and you know it {return actionDone();} o/~

Well I need major help. I need to get the wait mehod to work. It is absolutly necesary to my final project please I cannot get it to work properly.

Sounds like you're trying to write the Dialog class.

I have other things that I cant use dialouge class for. This is my simplest object. I need to be able to use wait and I have no idea why my notify's dont wake up the the waiting thread.

If ActionListener isn't getting the job done, maybe you should call ActionJackson.
