Q_ENUM and QVariant in a class in a namespace

[kshots]

I have a class with the structure:

namespace NS
{
   //Q_NAMESPACE   // Apparently I can't have multiple Q_NAMESPACE definitions if multiple headers have the same namespace declaration
   class A : public QObject
   {
      Q_OBJECT
   public:
      enum class MyEnum:quint8 {A,B,C};
      Q_ENUM(NS::A::MyEnum)
   };
}

I then want to create a QVariant from this enum:

void SomeFunc()
{
   QVariant V(NS::A::MyEnum::A);
}

... this fails, stating that there is no valid conversion from the enum to QVariant. Am I doing something wrong with the Q_ENUM macro above? I'm having difficulty deciphering when I should use Q_NAMESPACE, Q_ENUM_NS, Q_ENUM, etc. Apparently if an enum is in a class, you don't use Q_ENUM_NS even if the class is in a namespace. Any pointers?

According to the docs it must be Q_ENUM(MyEnum). And I'm not quite sure it is working with enum class

@Christian-Ehrlicher if memory serves well, enum class should already work.

It works, I am using it every day!

Evidently it doesn't work when used as above...

Can you provide a minimal project that triggers your issue ?
That will allow for everybody to work on the same base.

Sure, just add the code below to the post above (using the class in A.h and filling in a basic main() function for SomFunc() for a test project:

CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)

project(project LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)

find_package(Qt6 COMPONENTS Core REQUIRED)

set(sources main.cpp)
set(headers A.h)

add_executable(test ${sources} ${headers})
target_link_libraries(test PRIVATE Qt6::Core)

I couldn't include the code above because apparently the same code above is flagged as spam by the forum and refuses to post.
