java - 刽子手图片减半

Question

public Hangman(){

    Container content =getContentPane();
    content.setLayout(new GridLayout(0,1));

   btnAddWord.addActionListener(this);
   btnRestart.addActionListener(this);
   btnHelp.addActionListener(this);
   btnExit.addActionListener(this);

   panel2.add(label);
   panel3.add(word);
   panel4.add(btnAddWord);
   panel4.add(btnRestart);
   panel4.add(btnHelp);
   panel4.add(btnExit);

public static void main (String [] args){
    Hangman frame = new Hangman();
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400, 600);
    frame.add(panel1, BorderLayout.NORTH);
    frame.add(panel2, BorderLayout.CENTER);
    frame.add(panel3, BorderLayout.SOUTH);
    frame.add(panel4, BorderLayout.SOUTH);
}

好的，所以我弄清楚当点击错误的按钮时如何更改图片但问题是图片是一半，所以我的布局有问题......

在此处输入图像描述

好的，所以我很快就把它擦掉了。

public class HangPane extends JPanel {

    private JLabel lblImage;
    private JButton btnAction;
    private int guess = 0;

    public HangPane() {

        setLayout(new BorderLayout());
        lblImage = new JLabel();
        lblImage.setPreferredSize(new Dimension(46, 172));
        lblImage.setHorizontalAlignment(JLabel.CENTER);
        lblImage.setVerticalAlignment(JLabel.CENTER);
        btnAction = new JButton("Guess");

        String imageName = "HG0.png";
        lblImage.setIcon(new ImageIcon(imageName));


        btnAction.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {

                String imageName = "HG0.png";

                guess++;
                switch (guess) {
                    case 1:
                        imageName = "HG1.png";
                        break;
                    case 2:
                        imageName = "HG2.png";
                        break;
                    case 3:
                        imageName = "HG3.png";
                        break;
                    case 4:
                        imageName = "HG4.png";
                        break;
                    case 5:
                        imageName = "HG5.png";
                        break;
                    case 6:
                        imageName = "HG6.png";
                        break;
                    default:
                        guess = 0;
                        break;
                }

                lblImage.setIcon(new ImageIcon(imageName));

            }
        });

        add(lblImage, BorderLayout.CENTER);
        add(btnAction, BorderLayout.SOUTH);

    }
}
