- Added missing conversion from Qt::strong_ordering to
std::weak_ordering, std::partial_ordering.
- Added missing conversion from Qt::weak_ordering to
std::partial_ordering.
Usage of Q_IMPLICIT specifier in new std::*_ordering conversion functions leads to following ambiguity errors on WIN + MSVC configuration:
C:/Users/qt/work/qt/qtbase/src/corelib/global/qcompare.h(334): error C2440:
'static_cast': cannot convert from 'Qt::weak_ordering' to 'Qt::partial_ordering'
qcompare.h(334): note: 'Qt::partial_ordering::partial_ordering': ambiguous call to overloaded function
qcompare.h(249): note: could be 'Qt::partial_ordering::partial_ordering(Qt::partial_ordering &&)'
qcompare.h(153): note: or 'Qt::partial_ordering::partial_ordering(std::partial_ordering) noexcept'
qcompare.h(334): note: while trying to match the argument list '(Qt::weak_ordering)'
For solving the problem we can exclude the conversion function from the argument list(make it explicit in case of MSVC).
Q_COMPARE_CAST_IMPLICIT is used for setting explicit or implicit specifier depending on the compiler type
[ChangeLog][QtCore][QtCompare] Added missing conversions
from Qt ordering types to std ordering types.
