header problem(most likely)

sabatiel (7)
Hi, I cant find the error in my code even though i believe it to be a header problem.The bold underlined part of the code is what i believe to be causing the problem.

Error:
D:\qt\Tools\QtCreator\bin\untitled\city.h:11: Fehler: ISO C++ forbids declaration of 'zorro' with no type [-fpermissive]
 virtual zorro(QGraphicsScene &scene);

I am using qt creator and this is the entire project(atlest the files i have access too). The goal of the project is to create a little map with dots representing cities.I hope someone can help me fix this problem.

All functions (except constructors and destructors) must specify a return type.

virtual /*missing return type goes here*/ zorro(QGraphicsScene &scene);

Hope this helps.

Thanks Duoas I was so sure that it had to be a header problem that i forgot to look for the most basic mistakes.
