Java-Swing嵌入浏览器（一）

今天要说的额是浏览器的第一个版本是用DJnative-swt和swt包开发的调用本地浏览器和webkit浏览器的示例

这是我的工程目录【源码见最后】：

src下为写的源码，lib为引入的swt和DJnative和mozilla接口包~

我们来看两个类，此两个类是嵌入webkiet mozilla的内核浏览器 要用到xulrunner

这里有一句代码 就是下面这句

//指定xulRunner路径 如不指定就调用系统注册的xulrunner 注册为 xulRunner目录下的xulrunner --register-global
        NSSystemPropertySWT.WEBBROWSER_XULRUNNER_HOME.set(System.getProperty("user.dir") + "/xulrunner");

如果没有写这句代码引入工程下的xulrunner，那么就必须要进行注册注册为xulrunner --register-global 卸载为 xulrunner --unregister-global

XPCOMDownloadManager.java 类 调用mozilla内核浏览器
