What am i doing wrong with QFile::rename?

[MathSquare]

@
Qstring oldName = ("/home/myusername/Desktop/11.txt");
Qstring newName = ("/home/myusername/Desktop/22.txt");
bool QFile::rename ( const QString & oldName, const QString & newName );

http://qt-project.org/doc/qt-4.8/qfile.html#rename

Please tell me how to fix it and post the code since i am a new user to qt and coming from basic.net.

Seems like the title is different from your goal/link...

This works in windows, just change the oldName and newName to machine-specific uri.
Also, it is only a commandline program.

@#include <QCoreApplication>
#include <QFile>
#include <QDebug>

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
QString oldName = "D:\11.txt";
QString newName = "D:\22.txt";
qDebug()<<QFile::rename(oldName,newName);
return a.exec();
}@

Note that I used qDebug() to show if the "rename" is successful or not.
QFile::rename() will be only true if "oldName" exists!

I think the problem is that you are declaring twice the same variables. When you call the function with arguments that are existing variables, just use the name.

QFile::rename (oldName, newName );

PD: As somebody told you in another post, you should learn more about C++.
