[ubuntu] [enums] enums error: does not name a type

[amreo]

I have a c++ class TrisState:

#ifndef TRISSTATE_H
#define TRISSTATE_H
 
#include <QObject>
#define WIDTH 3
#define HEIGHT 3
class TrisState : public QObject
{
		Q_OBJECT
		Q_ENUMS(GameState)
	public:
		explicit TrisState(QObject *parent = 0);
		GameState x();
 
		enum GameState {
			Player1 = 'X',
			Player2 = 'O',
			Draw = '-',
			Void = ' '
		};
 
	private:
		GameState board[WIDTH][HEIGHT];
 
	signals:
 
	public slots:
 
};
 
#endif // TRISSTATE_H

#ifndef TRISSTATE_H
#define TRISSTATE_H

#include <QObject>
#define WIDTH 3
#define HEIGHT 3
class TrisState : public QObject
{
		Q_OBJECT
		Q_ENUMS(GameState)
	public:
		explicit TrisState(QObject *parent = 0);
		GameState x();

		enum GameState {
			Player1 = 'X',
			Player2 = 'O',
			Draw = '-',
			Void = ' '
		};

	private:
		GameState board[WIDTH][HEIGHT];

	signals:

	public slots:

};

#endif // TRISSTATE_H

and

#include "trisstate.h"
 
 
TrisState::GameState TrisState::x()
{
 
}

#include "trisstate.h"


TrisState::GameState TrisState::x()
{

}

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?

Hello,

in the header file first declare the enum before using it:

enum GameState {
	Player1 = 'X',
	Player2 = 'O',
	Draw = '-',
	Void = ' '
	};
 
GameState x();

enum GameState {
	Player1 = 'X',
	Player2 = 'O',
	Draw = '-',
	Void = ' '
	};

GameState x();

To copy to clipboard, switch view to plain text mode 

Best regards
