How to get the QNetworkConfiguration UserChoice dialog?

Question

Qt docu says I can get a popup for the user to choose the QNetworkConfiguration . But how can I do this?

When I have

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

how can I tell it I want the dialog. There is not setType function or ctor. What do I miss? Or am I just on the wrong platform (Win64)?

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，仅QNetworkConfigurationManager :: defaultConfiguration（）返回UserChoice类型的配置
