Thread: Declaration problems

I'm not positive, but I think you may be able to solve this problem with forward declarations, like this:

Code:

//FILE: AREA.H

#ifndef AREA_H
#define AREA_H

#include <QObject>

//Instead of including camera.h, do a forward declaration
class Camera;

class Area
{
public:
    Area(QString text);
    ~Area();

	static void Dispose();
	
    static QList<Area*> *areas;
    
    QList<Camera*> *cameras;
    QString       text;
private:
    QString name;
};

Do the same for camera.h (class Area; instead of #include area.h), and then in your .cpp implementations of each class, include the appropriate headers.

still don't work:

Code:

#ifndef CAMERA_H
#define CAMERA_H

#include <QObject>

class Area;

class Camera
{
public:
    Camera(QString text, Area* parentArea);
    ~Camera();

	QString text;
private:
	Area* parentArea;
	QString name;
};

#endif

Output: "'Area' is not a type"

Im thougth in one way to solve: putting the two classes declarations in the same header file, but wouldn't it be like "bad programming"?

Even with my strange idea of joining two classes in one header went wrong.

line 14 at camera.h file, and i will see the link thanks.

I have read the text in the link but everything that is there i already tried.

Ideas?

Ok, i found what was wrong: i had the following piece of code:

Code:

enum Types
{
    Camera,
    Area
};

So frustrating [:P]
