The problem is that buttonClickedEvent is a member function and you need a pointer to member in order to invoke it   Try this   void  MyClass   func  int   func    amp MyClass  buttonClickedEvent    And then when you invoke it  you need an object of type MyClass to do so  for example this    this- gt  func   lt argument gt      http   www codeguru com cpp cpp article php c17401 C-Tutorial-PointertoMember-Function htm
