    Default Action Listeners within and Action Listener on Panels

    Hello,

    I am working on creating a game in which after the user ends the session by pressing the "cash out" button, the game then displays a JLabel that asks them if they would like to play again. I also show them a "Yes" and "No" button.

    I am able to get the "Yes" and "No" buttons to display, but I can't get the buttons to do anything (my yes/no button action listeners aren't working).

    So far, I have the "Cash Out" button listener that will display the end points and then asks if they want to play again.

    Any feedback is highly appreciated!

    Thanks!

    Welcome to the forum! Please read this topic to learn how to post code correctly and other useful info for new members.

    Show the yes/no button actionListener code (hopefully commented) that isn't giving the desired results. Include enough info (other classes, comments, and supporting code) for someone who has never seen your code to understand what it's supposed to do. A runnable example that demonstrates the problem would be best.

    Here is my code:

     
        // creates listener for cash out button
        public class cashOutButtonListener implements ActionListener {
     
            public void actionPerformed (ActionEvent event) {
                cashOutLabel.setText("Your cash out value is: "+ currentTokens);
     
                //resiezes primary panel
                primary.setPreferredSize (new Dimension(300, 275));
     
                // creates label that asks question if they want to play again
                playAgainLabel = new JLabel("Would you like to keep playing?");
                playAgainLabel.setForeground(Color.MAGENTA);
                buttonPanel.add(playAgainLabel);
     
                //resizes button panel
                buttonPanel.setPreferredSize (new Dimension (275, 150));
     
                //creates yes and no buttons
                yesButton = new JButton ("Yes");
                noButton = new JButton ("No");
                buttonPanel.add(yesButton);
                buttonPanel.add(noButton);        
     
                // if the click "No" button, frame closes
                if ((JButton)event.getSource() == noButton) {
                    System.exit(0);
                }
     
                // if they click "Yes" button, Yes/No button are removed and current tokens set to 5
                if ((JButton)event.getSource() == yesButton) {
                    buttonPanel.remove(yesButton);
                    buttonPanel.remove(noButton);
                    buttonPanel.repaint();
                    spinResult = 0;
                    currentTokens = 5;
     
                }
     
            }


    --- Update ---

    Instead of making the buttons into action listeners, I just added if-statements, but it still won't work.

    still won't work.
    Is the listener added to the button? Add a println() that prints a message in the listener so you can see if it is called.

    BTW the reference from getSource() does not need to be cast to compare with another reference.
    If you don't understand my answer, don't ignore it, ask a question.
