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.
This is an overloaded function.
Implements three-way comparison of pointers.
Note: This function participates in overload resolution 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.
Returns an instance of Qt::strong_ordering that represents the relation between lhs and rhs.
This function was introduced in Qt 6.7.
