I have a c++ class TrisState:

Qt Code: 
  1. #ifndef TRISSTATE_H
  2. #define TRISSTATE_H
  3.  
  4. #include <QObject>
  5. #define WIDTH 3
  6. #define HEIGHT 3
  7. class TrisState : public QObject
  8. {
  9. 		Q_OBJECT
  10. 		Q_ENUMS(GameState)
  11. 	public:
  12. 		explicit TrisState(QObject *parent = 0);
  13. 		GameState x();
  14.  
  15. 		enum GameState {
  16. 			Player1 = 'X',
  17. 			Player2 = 'O',
  18. 			Draw = '-',
  19. 			Void = ' '
  20. 		};
  21.  
  22. 	private:
  23. 		GameState board[WIDTH][HEIGHT];
  24.  
  25. 	signals:
  26.  
  27. 	public slots:
  28.  
  29. };
  30.  
  31. #endif // TRISSTATE_H

and

Qt Code: 
  1. #include "trisstate.h"
  2.  
  3.  
  4. TrisState::GameState TrisState::x()
  5. {
  6.  
  7. }
To copy to clipboard, switch view to plain text mode 

When i compile the code i've two errors:
trisstate.h:13: error: 'GameState' does not name a type
GameState x();
^

and

trisstate.cpp:4: error: no 'TrisState::GameState TrisState::x()' member function declared in class 'TrisState'
TrisState::GameState TrisState::x()
^

What am i wrong?
