JBuilder
对于Visual Studio的宏，大家应该很熟悉了，这是一篇关于JBuilder实现类似Visual Studio的宏扩展功能，我们就通过对一段代码是否注释掉作为简单例子。大家可以实现自己的一些扩展，算是抛玉引砖了。 支持环境： Jbuilder 4.0 - JBuilder 7.0 使用JBuilder编译时需要在 Project ---> Project Properties ---> Required Libaries中加上Jbuilder下的 Open Tool SDK，编译成功后将生成的class打包成一个JavaCommentSwitch.jar文件，其中包含这样一个文件META-INF\Manifest.mf，该文件内容如下： Manifest-Version: 1.0 OpenTools-UI: JavaCommentSwitch 不需要什么详细的讲解，代码如下： /*=============================================== 文件一： IDEActions.java ===============================================*/ /** * Title: JBuilder IDE Toolbox * Description: http://www.vchelp.net/itbookreview/view_user.asp?user_name=ghost * Copyright: Copyright (c) 2002 Ghost Studio.
