    Description

       

      Using a list of Foobar pointers defined like

      class Foobar : public QObject {
          Q_OBJECT
          QML_ELEMENT
          QML_UNCREATABLE("Read only")
          Q_DISABLE_COPY(Foobar)
      
      public:
          Foobar(QObject* parent = nullptr) : QObject(parent) {}
          Q_INVOKABLE int baz() const { return 42; }
      };
      
      class Druggeljug : public QObject {
          Q_OBJECT
          QML_ELEMENT
          QML_SINGLETON
      
      public:
          Druggeljug(QObject* parent = nullptr) : QObject(parent) {
              for (int i = 0; i < 5; ++i) {
                  m_foos.append(new Foobar(this));
              }
          }
      
          Q_INVOKABLE QList<Foobar*> getList() const { return m_foos; }
      
      private:
          QList<Foobar*> m_foos;
      };
      

      used in

      function showList() {
              const l = Druggeljug.getList()
              for (const foo of l) {
                  console.log(foo.baz())
              }
          }
      

      works at runtime, but cannot be compiled:

      Warning: main.qml:12:30: Could not compile function showList: return type QList<Foobar*> cannot be resolved [compiler]
              const l = Druggeljug.getList()
                                   ^^^^^^^
