自绘16进制编辑框

这个东西的产生是因为有朋友需要一个16进制编辑器控件，但是网络上的大多数控件调用都不是那么方便

找了很多也不好用，才萌生了自己鲁一个16进制编辑框 控件，先后路过两个版本，第一个版本代码冗长，

框架设计不是这么合理，所以才有了现在的这个版本，目前这个版本是没有优化的版本，为了新手能看懂

大部分代码都没有优化，全部都是自己鲁，要用到自己的程序里面还欠缺一点，大家需要自己去熟悉框架

只有熟悉了框架，才能更好的修改，优化过后，是完全能胜任的，优点嘛就是简单，方便嵌入程序使用

缺点就是功能还没有这么多，不过大家可以关注，以后会有更多功能版本的出来，这里帖一下代码，代码大约有

1800行不到
