reading JSON file in Qt5

[LZAntal]

Hi,

I have been trying to figure out how to read a JSON file using Qt5 QJsonDocument with no success so far.
I can't find any examples online. If someone could give me a simple example I would appreciate it.

Here is my code::

QFile file;
file.setFileName("/tmp/settings.json");
file.open(QIODevice::ReadOnly | QIODevice::Text);
QJsonDocument settdoc;
settdoc.fromBinaryData(file.readAll());
qDebug() << settdoc.isNull();

QFile file;
file.setFileName("/tmp/settings.json");
file.open(QIODevice::ReadOnly | QIODevice::Text);
QJsonDocument settdoc;
settdoc.fromBinaryData(file.readAll());
qDebug() << settdoc.isNull();

To copy to clipboard, switch view to plain text mode 

settdoc.isNull() returns true, I can read the file into a stream without any issue and I validated the json as well.

Thank you

Laszlo
