I wish to see how QQmlListProperty is used. I tried the following but I am not sure if this is the correct way to do it. I got an error shown in the title.

aa.h

  1. #ifndef IMO
  2. #define IMO
  3.  
  4. #include <QQmlListProperty>

  7. class SubClass: public QObject
  8. {

  15.   QQmlListProperty <DummyClass> functionWhat()

  18.   }
  19.  
  20. private:
  21.   QList <DummyClass*> dummyList;
