Difference between QJsonValue and QVariant?

I'm working with Qt and JSON. Now, I have two options: QVariant and QJsonValue. I don't get the point in which they are different?

I know QVariant has some more methods and QJsonValue has the is*** methods(where QVariant has type). But is there any other main difference (maybe speed)? If no: Why are there two classes which can do nearly the same?

Solution

  • QVariant give you more flexibility in manipulating data.
