    Description

      I just upgraded to Qt 6.2.3 and I'm now getting errors in one of my moc files for a class that uses an enum in one of its slots.  The enum is inside of a namespace called enums, and in the moc file the enum part of the namespace name is being removed.  This looks very similar to the bug QTBUG-88125 which was apparently fixed in Qt 5.15, but still seems to be a problem in Qt 6.  I have attached a small sample project that reproduces the problem.

       

      Class.h

      #ifndef CLASS_H
      #define CLASS_H
      #include <QObject>
      
      namespace enums
      {
          enum class Cards
          {
              Clubs,
              Diamonds,
              Hearts,
              Spades
          };
      }
      
      class Class : public QObject
      {
          Q_OBJECT
      
      public:
          Class() {}
      
      signals:
          void cardPicked(enums::Cards card);
      
      public slots:
          void setCard(enums::Cards card) {}
      };
      
      #endif // CLASS_H
      

       

      main.cpp

      #include <QCoreApplication>
      #include "Class.h"
      
      int main(int argc, char *argv[])
      {
          QCoreApplication a(argc, argv);
          Class c;
      
          QObject::connect(&c, &Class::cardPicked, &c, &Class::setCard);
      
          return a.exec();
      }
