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...

When the macro QT_NO_CAST_FROM_ASCII is enabled, you can do something like:

QJsonDocument doc(jsonObject);
QByteArray docByteArray = doc.toJson(QJsonDocument::Compact);
QTextCodec *codec = QTextCodec::codecForName("UTF-8");
Qstring strJson = codec->toUnicode(docByteArray);

Or better, just use QLatin1String(QByteArray&), based on the example of TheDarkKnight:

QJsonDocument doc(jsonObj);
QByteArray docByteArray = doc.toJson(QJsonDocument::Compact);
Qstring strJson = QLatin1String(docByteArray);
