How to create JSON using QJsonDocument?

[ajaxcrypto]

Here is a small snippet

   QJsonValue value{QJsonValue::Object};
   value.toObject().insert("key", "value");
   QJsonDocument doc;
   doc.setObject(value.toObject());
   std::cout << doc.toJson().toStdString();

It however outputs a blank object i.e. {} in console. Why is that the case?

   QJsonValue value{QJsonValue::Object};
   value.toObject().insert("key", "value");

Does this alter your QJsonValue value ?

No.

@ajaxcrypto: Try this:

    QJsonValue value{QJsonValue::Object};
    QJsonObject object = value.toObject();
    object.insert("key", "value");
    QJsonDocument doc;
    doc.setObject(object);
    std::cout << doc.toJson().toStdString();
