c++ - 如何获取 QNetworkConfiguration UserChoice 对话框？

Question

Qt 文档说我可以获得一个弹出窗口供用户选择 QNetworkConfiguration。但是我该怎么做呢？

当我有

QNetworkConfiguration config;
QNetworkSession *networkSession = new QNetworkSession(config, &a);
networkSession->open();

我如何告诉它我想要对话框。没有 setType 函数或构造函数。我想念什么？或者我只是在错误的平台 (Win64) 上？

UserChoice The configuration is a placeholder which will be resolved to an actual configuration by the platform when a session is opened. Depending on the platform the selection may generate a popup dialog asking the user for his preferred choice.

根据 http://doc.qt.io/qt-5/bearer-management.html只有 QNetworkConfigurationManager::defaultConfiguration() 返回 UserChoice 类型的配置
