目录
时间不是很多了，我想压缩一下快点把属于毕设的这部分搞完，俺要出去旅游了。所以后面写的东西不会很多了。等我回来接着跟大家详细的分享技术。
一、本次修改
改的太多了，整个修改过程主要部分都在下面详细说明包括中间版本的文件。
二、GUI和Client之间联调
2.1 工程结构修改
为了更规范一些我把项目做了拆分，全局变量在global_var文件中。
tcp通信在tcp中，工具在tool里。GUI在show里。客户端的主程序就叫client
2.2 将TCP程序修改为可被其它程序调用

做了大改动现在的问题是
会闪退
原来是函数参数改完这面忘记改了
加上GUI后输出都会到GUI的OUTPUT导致直接闪退什么都看不到
终于是通信上了，其实这部分可以单独拿出来做个项目了哈哈，图形化的网络编程聊天室，就是要在优化优化现在就是个框架。
