Equivalent to Q_DECLARE_METATYPE(TYPE *) and Q_DECLARE_METATYPE(QQmlListProperty<TYPE>) QML_DECLARE_TYPEINFO (Type, Flags) Declares additional properties of the given Type as described by the specified Flags. Do I have to locally declare orientation as a metatype?The Q_DECLARE_FLAGS() macro does not expose the flags to the meta-object system, so they cannot be used by Qt Script or edited in Qt Designer. ignoretokens = QAXFACTORY_EXPORT \ QM_EXPORT_CANVAS \. The Q_D and Q_Q macros are part of a design pattern called the d-pointer (also called the opaque pointer) where the implementation details of a library may be hidden. ** Contact: ** ** This file is part of the QtCore module of the.

Current the only supported type info is QML_HAS_ATTACHED_PROPERTIES. The issue seems to be with the Q_DECLARE_OPERATORS_FOR_FLAGS declaration; if I remove it, the compilation issues with other flag types are resolved, but since this declares the operators for the flags, then the compiler won't accept the OR'd list. It associates a type name to a type so that it can be created and destructed dynamically at run-time. 5, most Qt header files included <QtGlobal>.
