java - 在 Java Swing 中嵌入 Firefox 浏览器

Question

我想知道是否可以将 Firefox 浏览器作为一个组件嵌入到基于 Java Swing 的应用程序中。

我在互联网上做了一些研究，但找不到答案。有些人建议使用 Java 中可用的其他浏览器组件。我不认为这是可取的，因为呈现引擎与 Firefox 不同。

有什么想法吗？非常感谢。

绝对是我之前做过的，请查看 Mozilla Embedding for Java

这里是一些示例代码

import java.awt.Color;
import java.awt.Component;
import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.FileNotFoundException; 
import java.io.File; 

import javax.swing.*;

import org.mozilla.xpcom.*; 
import org.mozilla.interfaces.*;
