Question

I have class Content in my project as follows:


#ifndef CONTENT_H

#define CONTENT_H

#include <QDateTime>

class Content

{

public:

    //Content();

protected:

    QString Sender;

    QDateTime TimeSent;

    QString Text;

    QString Picture;

    void SetText();

    void SetImage();

    void SetTime();

    QString GetTimeSent();

};



#endif // CONTENT_H

When I compile the project, I get error in QT sources

This is compile output:
