How to convert a QJsonObject to QString


I have a QJsonObject data and want to convert to QString. How can I do this? Searched for help in Qt, it only can convert QJsonObject to QVariantMap...

Thanks in advance.


Solution

  • 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));
