一个框架基础的东西,一般也是操作的最基础的类,比如char、int、bool等,有时出现内存泄露的问题导致错误的抛出,但是C++开发有的时候就算是抛出异常,那也是靠经验来积累才能非常快速准确的找出错误所在,这就需要在框架中需要添加日志管理的接口,日志管理的好处就是开发者自身在找异常时提供参考,另一个就是如果用户操作时出现问题,也可将日志反馈,帮助快速解决问题;总之了为了更好的扩展完善我的框架,我详细列一下这个基础服务库(XPCore)包含内容:

写到这,相信应该明白为什么要写这个库了,这是这个插件式框架的基石,有了它我就可以扩展了:这个插件式框架的主要思想就是:框架的开发与插件的开发要完全独立,插件间也要完全独立,框架要能实现动态加载插件中定义的方法和界面的对应的资源加载,所以用LUA角本定义配置信息,插件Dll开放指定两个方法:AutoStart(加载命令和条件绑定资源)和LoadStringResource(加载字符和图标资源)两个方法就可以,具体调用可以上面提到的DLLManager,来调用定两个方法,实现资源加载,动态生成控件和根据绑定条件刷新状态,所有的绑定都是通过字符串来实现。
最后赋上运行图片(主界面和插件管理界面),下一篇将写一下如何基于SharpUI编写一个自己要想的控件(以插件管理器中的导航面版为例):
界面中所有菜单和工具按钮全是通过Base插件中自动生成。
