Description

If I have C++ code like this:

namespace aaa::Data {                                                                                                                                                           
        Q_NAMESPACE                                                                                                                                                             
        QML_NAMED_ELEMENT(Data)                                                                                                                                                 
        QML_UNCREATABLE("C++ namespace")                                                                                                                                        
        Q_CLASSINFO("RegisterEnumClassesUnscoped", "false")                                                                                                                     
                                                                                                                                                                                
   enum class DType : uint8_t {                                                                                                                                                 
     A, B                                                                                                                                                                       
   };                                                                                                                                                                           
   Q_ENUM_NS(DType)   
}

then I can use "DType" enum in QML like this:

Item {
  property int secret: Data.DType.A  
}

If I tried to use "Data.A" instead of "Data.DType.A":

Item {
  property int secret: Data.A  
}

I got warning during running the application: "Unable to assign [undefined] to int" .

But qmllint produces no warning about "property int secret: Data.A".
While usage of "Data.Foo" force it produce warning.

I suppose this is because of "qmltypes" generated by build system (I use cmake + qt_add_qml_module) do not distinguish between cases when RegisterEnumClassesUnscoped = true and = false.

It would be nice if qmllint also produces warning like "Unable to assign [undefined] to int"
