Qt: How can I open the text file in relative path?

Question

QFile file("../studentdata/students.txt");
file.open(QIODevice::WriteOnly| QIODevice::Text);

qDebug()<<file.isOpen()<<file.isReadable()<<file.isWritable();

I want to open the file students.txt with relative path, but the qDebug result is false false false

does it work if you pass absolute path to QFile constructor? — Evgeny Timoshenko, Jun 05 '16 at 09:16

Your working directory may not be what you expect. Check it with QDir::currentPath() . Also check the QFile error string, so print file.errorString() after failed opening. For instance your application may not have permissions to write to this file.

 QFile file("studentdata\students.txt");
 file.open(QIODevice::WriteOnly| QIODevice::Text);

change the slash - it prints true, false, true. (:
