wxPython 客户端登录流程的拟定

登录函数的初步实现：

def Login(self, event):
    if (self.datacenter._netstat == 0):
        lib.MyDialog(u"网路状态",u"网路异常，请检查网络...")
    else:
        lib.udpFindCcu(self.datacenter, self.devdb.getFindCcu())
        if (bool(self.datacenter.ccuArray)):
            self.login_zk_id = self.TextCtrl_login_zkid.GetValue()
            if (self.datacenter.ccuArray.has_key(self.login_zk_id)):
                lib.MyDialog(u"登录方式",u"已经搜索到对应主机开始本地登录")
            else:
                lib.MyDialog(u"登录方式",u"未搜索到对应主机开始远程登录")
        else:
            lib.MyDialog(u"登录方式",u"未搜索到主机直接远程登录")

        if (self.datacenter._netstat == 0):
            log.info(u"网路异常，开始本地发现"+self.login_zk_id)
