Qt how to open a file in the current directory? or what's wrong with that?

I am trying to open an xml file in the current location of the executable

        QString path = QDir::currentPath();
        path.append("/acc.xml");
        QFile file(path);

        if(!file.open(QIODevice::ReadOnly))
        {
            insertItem("IO ERR");
        }

  • When I run it from the creator of Qt, everything works. currentPath()returns the path to the executable folder

  • When I go to the folder project-build-desktop/and try to start it manually currentPath()returns/home/user/Documents

EDIT

also tried with the same results:

Qt::current().path();
Qt::current().absolutePath();

Try using QCoreApplication :: applicationDirPath () instead of QDir :: currentPath ().

See http://doc.qt.io/qt-5/qcoreapplication.html#applicationDirPath for details
