struct Qt::has_qt_compare_three_way< T, typename >

\inmodule QtCore \inheaderfile QtCompare

A type trait for checking if a type supports {compareThreeWay()}.

Since

6.12

This struct is a \l {https://en.cppreference.com/w/cpp/named_req/UnaryTypeTrait} {UnaryTypeTrait} that inherits {std::true_type} if T supports three-way comparison via {compareThreeWay()}, and {std::false_type} otherwise.

Use Qt::if_has_qt_compare_three_way to constrain function templates on this property.
