I'm trying to open a file for reading using qt and it doesn't open it, it returns an error 5. I don't know why ?

loadObjModel("box.obj");
QFile obj_file(path) ;

QString errMsg;
QFileDevice::FileError err = QFileDevice::NoError;
if (!obj_file.open(QIODevice::ReadOnly)) {
    errMsg = obj_file.errorString();
    err = obj_file.error();
    qDebug() << QString(" err %1").arg(err) ;
}
if (!obj_file.open(QFile::ReadOnly))
{
    qDebug() << QString("cannot open %1").arg(path) ;
    return ;
}

Hi,

The most likely is that your file is not a the path you are providing. For example, if your file is located in your sources and you wrote a relative path in your application code then it won't find it because they are not in the same folder. That's because by default Qt Creator uses Shadow Builds (which is a good thing).
