    Default need help with my code!

    hey everyone,

    i have been struggling with 2 frames.
    the question here is, how can you let a frame disappear and let another one appear.
    im making a game and when i click on start it needs to show another frame.

    can someone help me with this?

    got the whole code here:

    import java.awt.Color;
    import javax.swing.JButton;
    import javax.swing.JFrame;
    import javax.swing.JPanel;
     
     
    public class RushhourStart
    {
     
            public static void main(String [] args)
            {
     
                    JFrame frame = new JFrame();
                    frame.setSize(700, 700);
                    frame.setTitle("Rushhour");
                    frame.setLocationRelativeTo(null);
                    frame.setDefaultCloseOperation(JFrame. EXIT_ON_CLOSE);
                    frame.setVisible(true);
     
                    makegame(frame);       
     
            }
     
    public static void makegame(JFrame frame)
     
            {
     
                            JFrame gameframe = new JFrame();
                gameframe.setSize(700, 700);
                gameframe.setLocationRelativeTo(null);
                gameframe.setDefaultCloseOperation(JFrame. EXIT_ON_CLOSE);
     
     
                makeBord panel = new makeBord();
                panel.setLayout(null);
                panel.setBackground(Color.black);
                frame.add(panel);
     
                JButton Start = new JButton("START SPEL");
                Start.setBounds(250, 100, 200, 50);
                panel.add(Start);
                Start.addMouseListener(panel);
     
                JButton Highscore = new JButton("HIGHSCORES");
                Highscore.setBounds(250, 180, 200, 50);
                panel.add(Highscore);
     
                JButton Exit = new JButton("Exit");
                Exit.setBounds(250, 260, 200, 50);
                panel.add(Exit);
     
        }
     
     
    }
     
     
     
     
     
     
    // second class:
     
     
    import java.awt.event.MouseEvent;
    import java.awt.event.MouseListener;
    import javax.swing.JPanel;
     
    public class makeBord extends JPanel implements MouseListener {
     
     
            @Override
            public void mouseClicked(MouseEvent arg0) {
     
            }
     
            @Override
            public void mouseEntered(MouseEvent arg0) {
                    // TODO Auto-generated method stub
     
            }

                    // TODO Auto-generated method stub
     
            }

    Are you sure you aren't looking for CardLayout?

    If you want to hide one JFrame and show another, you do just that: call setVisible(false) on the first JFrame and setVisible(true) on the second JFrame. Which part of that is giving you trouble?

    Okay, and can't you call setVisible(false) on your first JFrame and setVisible(true) on your gameframe?

    Again, it sounds like you're actually looking for a CardLayout. Have you looked into that at all?

    So your actual question is not how to go from one JFrame to another, but how to add a menu to two JFrames?

    JFrame does not give the option to set the modality, so a JDialog is a much better choice for a second or child window to open from a JFrame. Also, you should be controlling the GUI elements from another class, as in a Model-View-Controller design, so that the program flow is not dependent upon the existence of or controlled by a particular GUI instance that may come and go.

    im going to look into a CardLayout, thanks for helping!

    well greg its for a game, when i press Start it should open a frame and let the other dissapear (or be on top of the other one)

    edit: will look into JDialog as well

    Right, most games don't open in one window, close that window, and then open another window. They simply change what's on the first window. That's where CardLayout comes into play.
