如何在 Java 中创建自定义 JButton 类? [英] How to create a custom JButton class in Java?

问题描述

恐怕我没有任何代码，因为我真的不知道自己在做什么.我正在尝试通过创建一个基本游戏来学习一些 Java 并想要制作一个菜单.我想要做的是有一个带有自定义 JButton 的类(基本上是一个特定大小的 JButton 和背景上的图片，特殊格式等)，它可以从另一个类调用，并在调用时给出自定义文本.我的问题是，如何创建可以在外部调用的自定义按钮?

I'm afraid I don't have any code because I don't really know what I'm doing. I'm trying to learn some Java by creating a basic game and want to make a menu. What I want to do is have a class with a custom JButton (basically a JButton of a certain size and a picture on the background, formatted specially, etc.) which can be called from another class and given custom text when it is called. My question is, how do I create the custom button which can be called externally?

推荐答案

创建一个类并将其扩展到 JButton，如下所示，您可以在那里更改与 JButton 相关的所有类型.

create a class and extend it to JButton like below and there you can change all sort of things that has to do with JButton.

import javax.swing.JButton;

public class CustomJButton extends JButton {

    public CustomJButton() {
        this.setText("Custom JButton");
        // initialize
    }

    // add your own methods or override JButton methods
    public void myFunc(){

    }
}
