Function Documentation
[constexpr noexcept, since 6.7, deprecated in 6.8] template <typename LeftType, typename RightType, Qt::if_compatible_pointers<LeftType, RightType> = true> Qt::strong_ordering compareThreeWay(const LeftType *lhs, const RightType *rhs)
This function is deprecated since 6.8. We strongly advise against using it in new code.
Wrap the pointers into Qt::totally_ordered_wrapper and use the respective Qt::compareThreeWay() overload instead.
Implements three-way comparison of pointers.
Returns an instance of Qt::strong_ordering that represents the relation between lhs and rhs.
Constraints
Participates in overload resolution only if LeftType and RightType are the same type, or base and derived types. It is also used to compare any pointer to std::nullptr_t.
This is an overloaded function.
This function was introduced in Qt 6.7.
