How to convert a QJsonObject to QString

Remembering when I first needed to do this, the documentation can be a bit lacking and assumes you have knowledge of other QJson classes.

To obtain a QString of a QJsonObject, you need to use the QJsonDocument class, like this: –

QJsonObject jsonObj; // assume this has been populated with Json data

QJsonDocument doc(jsonObj);
QString strJson(doc.toJson(QJsonDocument::Compact));
