CardLayout - How to Delete current card (Java Swing)

How would one delete the current card that the user is on. I know how to go through a card layout using the next and previous function, but how would one remove the current frame that the user is on? For example, if I have a program where I am currently on the 3rd panel out of 5 total panels, how would I delete the current one which is the 3rd panel. Once you remove it, the next or previous one replaces it. I do not think removecurrentlayout can be used cause I am not removing a component. For example, in the code, how would I go about delete Card 3 if I am on that.

import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.Container;  
import java.awt.Dimension;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class CardLayoutProg {

    public static void main(String[] args) {

        JFrame frame = new JFrame("CardLayout");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container contentPane = frame.getContentPane();
        JPanel buttonPanel = new JPanel();
        JButton nextButton = new JButton("Next");
        buttonPanel.add(nextButton);
        contentPane.add(buttonPanel, BorderLayout.SOUTH);
        final JPanel cardPanel = new JPanel();
        final CardLayout cardLayout = new CardLayout();
        cardPanel.setLayout(cardLayout);

        for (int i = 1; i <= 5; i++) {
          JButton card = new JButton("Card " + i);
          card.setPreferredSize(new Dimension(200, 200));
          String cardName = "card" + 123123;
          cardPanel.add(card, cardName);
        }

        contentPane.add(cardPanel, BorderLayout.CENTER);
        nextButton.addActionListener(e -> cardLayout.next(cardPanel));

        frame.pack();
        frame.setVisible(true);
  }
}

Solution

Unfortunately the CardLayout does not tell you which card (JPanel) is currently being displayed.

Check out Card Layout Focus for a class that extends the CardLayout to provide this functionality.

You would use the getCurrentCard() method to access the panel currently being displayed.

Then once you get the card currently being displayed you can remove it from the parent panel using by the remove(...) method of the Container class.

You would just use the class as follows:

//final CardLayout cardLayout = new CardLayout();
final RXCardLayout cardLayout = new RXCardLayout();

The logic for your "Remove" button would be:

cardPanel.remove(cardLayout.getCurrentCard());
