基于PYQT的MQTT协议测试工具

这段时间公司有个项目使用到了MQTT的协议与智能硬件终端进行通信，需要对通讯协议进行验证，正好这段时间一直在研究PYQT，正好写个GUI小工具，给测试组的同事们使用

主界面
主界面主要实现Publish和Subscribe 消息订阅和发送，使用了PAHO的mqtt库，我这边主要是实现了一个界面的封装

设置界面
设置界面主要是使用了python自带的sqlite数据库保存用户连接MQTT服务器时的一些个性化参数，用户可以对自己的保存的连接进行个性化命名，选中相应的连接，点击ok即可

整个小工具去掉库文件，自己实现的代码在1000行左右，只是一个初级版本，其中ConfigDialog.py就是设置页面编码，mtest.py是主界面的编码，mqttimage文件是一些图片的集合，对PYQT不是很了解的同学可以去查阅一下相关资料。
