how to use a class in multiple panels

Question

i'm making a tank game. to avoid redundancy to make my buttons in the menupanel i wrote a class button:

package menu;

import java.awt.Image;
import java.awt.event.ActionListener;

import javax.swing.ImageIcon;
import javax.swing.JButton;

public class Button extends JButton{

    public JButton button;
    public ImageIcon buttonImage;

    public int x, width, height;

    public String backgroundPath;
    public int y;



    public Button(String backgroundPath,int x, int y, MenuPanel menuPanel)

    {
        super();
        this.backgroundPath = backgroundPath;
        this.x = x;
        this.y = y;

        buttonImage = new 
            ImageIcon(PlayPanel.class.getResource(backgroundPath));
        this.setIcon(buttonImage);
        this.setBounds(x, y, buttonImage.getIconWidth(), 
            buttonImage.getIconHeight());
        this.addActionListener(menuPanel);   
    }
}

in the constructor of the method i have MenuPanel menupanel but i want to be able to use this code is multiple panels like the QuitPanel, HighScorePanel, ...etc.

i don't know which parameter i have to use for this so i'm stuck.

thanks in advance!!

Answer 1

将MenuPanel menuPanel参数更改为ActionListener侦听器，因为这样做的唯一原因是使向其附加ActionListener更加容易，因此按钮不需要了解MenuPanel

Answer 2

You can declare an interface IPanel and make your QuitPanel , HighScorePanel , and MenuPanel implement that interface. I believe each of these panels must be implementing some common methods whose declarations can be moved to IPanel interface. Then you can pass IPanel as an argument in constructor rather than MenuPanel .

Answer 3

如果MenuPanel是JPanel的实例，那么您可以像这样更改代码...

public Button(String backgroundPath,int x, int y, JPanel pane);
