I build a game in swing and I have two JPanels for menu and the game itself. I want to switch from the menu panel to the game panel and from the game to the menu using JButtons. but every time I switch from the menu to the game, I want to start over the game and send the name of the player from some textField in the menu panel. so I need to make now instance of the game panel. How can I do this?
Here's the menu panel:
public class MenuPanel extends JPanel {
private JPanel contentPane;
private JTextField txtName;
public MenuPanel(JPanel panel) {
setLayout(null);
contentPane = panel;
JButton btnStart = new JButton("Click to start the game");
btnStart.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
CardLayout cardLayout = (CardLayout) contentPane.getLayout();
cardLayout.show(contentPane, "Game Panel");
}
});
btnStart.setFont(new Font("Baskerville Old Face", btnStart.getFont().getStyle(), 25));
btnStart.setBounds(290, 510, 290, 70);
add(btnStart);
txtName = new JTextField();
txtName.setBounds(450, 460, 160, 20);
add(txtName);
txtName.setColumns(10);
JLabel lblName = new JLabel("Enter your name:");
lblName.setForeground(SystemColor.text);
lblName.setFont(new Font("Bradley Hand ITC", Font.BOLD, 20));
lblName.setBounds(260, 460, 180, 20);
add(lblName);
JLabel lblGame = new JLabel("RUMMIKUB GAME");
lblGame.setForeground(new Color(0, 0, 0));
lblGame.setHorizontalAlignment(SwingConstants.CENTER);
lblGame.setFont(new Font("Goudy Old Style", lblGame.getFont().getStyle(), 50));
lblGame.setBounds(180, 100, 500, 140);
add(lblGame);
}
}
Here's the game panel:
public class GamePanel extends JPanel {
private JPanel contentPane;
private JButton btnReturnToMenu;
private TileButton[][] buttons = new TileButton[Constants.ROWS_IN_PLAYER_BOARD][Constants.COLUMNS_IN_PLAYER_BOARD];
private JLabel lblHello;
private TileButton btnThrownByPlayer;
private TileButton btnThrownByOpponent;
private Point clickedButton;
private JButton btnPullFromPool;
private JButton btnFinish;
private Game game;
public GamePanel(String firstPlayerName, String secondPlayerName, JPanel panel) {
setLayout(null);
contentPane = panel;
clickedButton = null;
game = new Game(firstPlayerName, secondPlayerName);
lblHello = new JLabel("hello " + firstPlayerName + " and " + secondPlayerName);
lblHello.setBounds(10, 10, 250, 40);
add(lblHello);
//initiate exit button.
btnReturnToMenu = new JButton("Return To Menu");
btnReturnToMenu.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
CardLayout cardLayout = (CardLayout) contentPane.getLayout();
cardLayout.show(contentPane, "Menu Panel");
}
});
btnReturnToMenu.setFont(new Font("Mongolian Baiti", Font.BOLD, 16));
btnReturnToMenu.setBounds(10, 70, 200, 40);
add(btnReturnToMenu);
// initiate finish button.
btnFinish = new JButton("Finish");
btnFinish.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (btnFinish.isEnabled()) {
if (game.finish()) {
JOptionPane.showMessageDialog(null,
"You finish the game.\nCongratulations, you are the winner!!!");
CardLayout cardLayout = (CardLayout) contentPane.getLayout();
cardLayout.show(contentPane, "Finish Panel");
} else {
btnFinish.setEnabled(false);
JOptionPane.showMessageDialog(null, "You didn't finish the game yet");
}
}
}
});
btnFinish.setFont(new Font("Mongolian Baiti", Font.BOLD, 16));
btnFinish.setBounds(750, 50, 100, 40);
add(btnFinish);
}
}
Here's the frame:
public class MainFrame extends JFrame {
private JPanel contentPane;
private GamePanel gamePanel;
private MenuPanel menuPanel;
private FinishPanel finishPanel;
private MainFrame() {
//super();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(233, 55, 900, 627);
setResizable(false);
JPanel contentPane = new JPanel();
contentPane.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 0));
contentPane.setLayout(new CardLayout());
menuPanel = new MenuPanel(contentPane);
gamePanel = new GamePanel("", "", contentPane);
finishPanel = new FinishPanel(contentPane);
contentPane.add(menuPanel, "Menu Panel");
contentPane.add(gamePanel, "Game Panel");
contentPane.add(finishPanel, "Finish Panel");
getContentPane().add(contentPane, BorderLayout.CENTER);
pack();
setLocationByPlatform(true);
setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new MainFrame();
}
});
}
}
Thanks for the help!

how can I open the JFrame in mainClient.java when I click on the singleplayer button, and the JFrame in mainServer.java when I click on the multiplayer button?
Create ActionListeners for your buttons. Define your frames, and you can access them with your class name. For example;
class mainClient extends JPanel {
JFrame mainClientFrame = new JFrame();
}
and then;
mainClient mc = new mainClient();
mc.mainClientFrame.setVisible(true);
if you want to use this frames in your main void, define them static.
class mainClient extends JPanel {
static JFrame mainClientFrame = new JFrame();
}
I made the Card Layout Working completely fine but what happened now is I added a keylistener to the object character which is a JLabel so whenever the person presses up the character should move up but it does absolutely nothing!
I also tried replacing it with a button which moves it when clicked and it worked completely fine. Also I tried changing the event meaning I changed that if they press up then the image of the town map would change but still no effect so it seems there is something wrong with my KeyListener

Add following code in your programme.
public static JPanel mainmenu = new JPanel();
public static JPanel loginpanel = new JPanel();
or initialize mainmenu & loginpanel before adding them into the game panel.
when you call game.add(loginPanel, "2") loginPanel is null
I need to make a GUI that asks the users for details and then save them in a linked list. I wanted to use the CardLayout to switch from one frame to another, which is something I'm doing for the first time. I have done probably less half of what I need to do and here I am quite lost in this part. The code below compiles and executes but when I click the buttons, the desired change does not happen . What could be wrong?

The main problem is the use of null-layouts and these lines of code:
frame.getContentPane().add(mdbw);
frame.getContentPane().add(buttonPanel);
First you add the panel using the CardLayout to BorderLayout.CENTER, then you "overlay" it with your buttonPanel, which is using null-layout.
I would go with a simple FlowLayout (the default layout-manager for a JPanel) for the buttonPanel and add it to the BorderLayout.SOUTH of the contentPane. I would also strongly recommend reading this tutorial.
So remove the following lines of code:
buttonPanel.setLayout(null);
...
addButton.setBounds(100, 400, 100, 100);
editButton.setBounds(200, 400, 100, 100);
deleteButton.setBounds(300, 400, 100, 100);
browseButton.setBounds(400, 400, 100, 100);
searchButton.setBounds(500, 400, 100, 100);
and change frame.getContentPane().add(buttonPanel); to frame.getContentPane().add(buttonPanel, BorderLayout.SOUTH);.
Also forget about the null-layout / setBounds() in your Window-classes.
(Note that you still won't see the text change if you press a button because you always add a JLabel with the same text ("Memory Files") to your Windows.)

I'm not sure whether it helps (sorry but your code is too large and bad formatted, so I cannot understand it), but you can try to revalidate and repaint the root pane or content pane of JFrame each time when you update your GUI.
Something like this
public static void updateRootPane(JComponent aComponent) {
Window w = SwingUtilities.windowForComponent(aComponent);
if (w instanceof JFrame) {
((JFrame) w).getRootPane().revalidate();
((JFrame) w).getRootPane().repaint();
} else if (w instanceof JDialog) {
((JDialog) w).getRootPane().revalidate();
((JDialog) w).getRootPane().repaint();
}
}
