QSettings::setPath don't work?

[oficjalne100]

Hello
I want set default path to ini file for my program. Default path must be current working directory. So I think that QSettings::setPath is excelent for that. I add following line in main function at very begin in my program (main function):
QSettings::setPath(QSettings::IniFormat, QSettings::SystemScope, ".");
But it does not work (i don't see the file with settings).
I try also:
QSettings::setPath(QSettings::IniFormat, QSettings::UserScope, ".");
But it does not work either.
How to set default path for ini file for my program?

Works fine here:

#include <QtGui>
#include <QDebug>
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    QSettings::setPath(QSettings::IniFormat, QSettings::SystemScope, ".");
 
    QSettings s("settings.ini", QSettings::IniFormat);
    s.setValue("test", "value");
}

#include <QtGui>
#include <QDebug>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QSettings::setPath(QSettings::IniFormat, QSettings::SystemScope, ".");

    QSettings s("settings.ini", QSettings::IniFormat);
    s.setValue("test", "value");
}

To copy to clipboard, switch view to plain text mode 

$ cat settings.ini
cat: settings.ini: No such file or directory
$ ./simple_example
$ cat settings.ini 
[General]
test=value

$ cat settings.ini
cat: settings.ini: No such file or directory
$ ./simple_example
$ cat settings.ini 
[General]
test=value

Be careful though, the current working directory is a moving target and often not writeable.
