python--DenyHttp项目(2)--ACM监考客户端测试版(1阶段客户端总结)

  客户端: 

1.既然脚本是让别人用的,怎么说也得有个界面,(虽然很low)

'''
DenyManager.py
调用客户端与客户端界面
'''
from DenyClient import *
from DenyGui import *

if __name__ == '__main__':
    clientConncet = DenyHttpClient()
    clientGui = DenyHttpGui()     

2.客户端的界面很简单,签到还没写,(构思中...)其实能用的就一个比赛开始的Button

这是后台跑的数据

这个连接服务器的messageBox为了改变比赛开始Button的状态为不可点击

检查版本信息,在确定开始比赛之前检查版本信息,版本不对,更新吧(下个新版的就好了)

之后,开始比赛!
