problem with constructor and inheritance QFile object

[naturalpsychic]

here is my code:

in _File.h:

#include <QString>
#include <QFile>
 
class _File : public  QFile
 
 
{
    Q_OBJECT
 
public:
       _File();
      _File(const QString &name);
....//and it goes on
};

#include <QString>
#include <QFile>

class _File : public  QFile


{
    Q_OBJECT

public:
       _File();
      _File(const QString &name);
....//and it goes on
};

To copy to clipboard, switch view to plain text mode 

in _File.cpp

_File::_File() :
        QFile()
 
    {
        this->setProgress(0);
 
        this->setFilename("");
           }
 
 
    _File::_File(const QString &qtname)
        :  QFile(name)
    {
 
        this->setProgress(0);
...}}

_File::_File() :
        QFile()

    {
        this->setProgress(0);

        this->setFilename("");
           }


    _File::_File(const QString &qtname)
        :  QFile(name)
    {

        this->setProgress(0);
...}}

To copy to clipboard, switch view to plain text mode 

and it goes on

but it has got compilation errors now. it says :
QFile::QFile(const QFile&) is private

within this context; when i click "within this context" it takes me to starting braces of _File class in header file


I am so over this error now, i have been trying to resolve this error for about 2 hours now...any help would be appreciated. thanks
