weChatThread线程类
之前一直不会python多线程，写这个程序的时候，发现不用多线程会陷入无限未响应状态。于是学了半天python多线程，但是在主函数里写的时候，发现一个问题，Ui主线程和工作线程没有分离，使用itchat等库的时候会堵塞主线程，换句话说PyQt中子线程不能操作GUI界面。之前写的多线程仍然属于Ui主线程，是其子线程，所以才造成未响应。
既然知道问题了，那就查资料解决问题，后来，在几篇博客上找到了解决办法
然后仿照第一篇博客，重写了QThread类，并借鉴第三篇博客，学会了PyQt多线程中的信号/槽机制，用来传递参数。

程序界面
程序界面仍然由Qtdesigner设计
后记
第一次尝试多线程编程，并且具体应用到实际项目中去，收获良多。
最近打算学点Django，有没有推荐教程？
