Does Qt have its own boost::optional alternative?

Question

Does Qt have its own boost::optional alternative, or should I just use boost::optional?

Answer 1

In C++17 there was introduced std::optional: https://en.cppreference.com/w/cpp/utility/optional

I think it's more usefull in Qt project, than boost one. There is still no any QOptional class in Qt.

Answer 2

Qt has a 'variant' type, but not an 'optional' type. I think that boost::optional (or, in newer C++ versions, std::optional) is a reasonable choice.
