QtCS2016 MetaObject

• qMetaType<const T>() == qMetaType<T>()
  • Because QMetaObject::normalizedType("const T") == "T"
  • Fix it
• Q_NAMESPACE
  • Keep it in 5.8
  • look into having it with multiple .h
  • Q_ENUM_NS(OtherNamespace::Enum) or using Enum = OtherNamespace::Enum; is a good idea
• Direct property access via the qt_static_metacall
  • qdbusxml2cpp
  • Add property & setProperty to QDBusAbstractInterfaceBase
• Generated hash table
  • properties, methods, enums
  • hashing table needs to encode the type (Q_SIGNAL_CODE)
  • perfect hashing doesn't help
  • check if we can encode the hashing of the entire hierarchy
  • "prelink" the class to its parent, recursively, but check at runtime

• For Qt6:
  • metatype vs C++ RTTI
  • qMetaType<T>() == &typeid(T)
