The QJsonObject class encapsulates a JSON object, where the keys are unique strings and the values are represented by a QJsonValue.

Description

The QJsonObject class encapsulates a JSON object.

A JSON object is a list of key value pairs, where the keys are unique strings and the values are represented by a QJsonValue.

A QJsonObject can be converted to and from a QVariantMap. You can query the number of (key, value) pairs with size(), insert(), and remove() entries from it and iterate over its content using the standard C++ iterator pattern.

QJsonObject is an implicitly shared class, and shares the data with the document it has been created from as long as it is not being modified.

You can convert the object to and from text based JSON through QJsonDocument.
