I have a class which shows a gui
As well as that there are action listeners for various button-presses, apart from that, nothing else.

When one of the buttons is pressed, within the action listener i call a second class........

mainGui.butStart.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
            callConnect = new Connect();
           callConnect.callResponder(mainGui);
        } /* end actionPerformed */  
}); /* end addActionListener */

This class also shows a gui.

When the cancel button on that gui is pressed, as follows.........i want it to return to the previous gui, but when i do that the first gui disappears as well. How can i stop that?

settingsGui.butCancel.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
                           
               mG.butStart.setEnabled(true);
             mG.butStop.setEnabled(false);
               
                settingsGui.hide();
           
           
           }
 });    


How come when i do the .hide(), the other gui disappears also and how do i stop it from happening?

settingsGui is a panel? JFrame?

if you want both of them open are you refering to like a MDI model? (Multiple Document Interface) an example of this model is Ms Word version 97 where there was one big window (parent window) and mulitple other windows (child) anyways I'm sure you know what I'm talking about.

is that what you want?
You can look into the JInternalFrame and the JDesktopFrame classes for more information

Both the first gui (mainGui) and the second one (settingsGui) are JFrames.

When i click a 'Cancel' button on the second gui (settingsGui) why does the gui behind it (mainGui)also disappear? And how can i solve it?

class Frame1 extends JFrame {
      public Frame1() {
            setSize(200, 300);
            JButton b = new JButton("Open");
            b.addActionListener(new ActionListener() {
                  public void actionPerformed(ActionEvent e) {
                        new Frame2(Frame1.this); ---> referes to the class Frame1
                  }
            });
            this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            this.getContentPane().add(b);
            this.show();
      }
}

class Frame2 extends JFrame {
      public Frame2(final JFrame caller) {
            setSize(200, 300);
            JButton b = new JButton("Close");
            b.addActionListener(new ActionListener() {
                  public void actionPerformed(ActionEvent e) {
                        caller.show();
                        Frame2.this.hide();
                  }
            });
            this.getContentPane().add(b);
            this.show();
      }
}

public class Test6 {

      public static void main(String[] args) {
            new Frame1();
      }
