QJson only saves null value in QT

Vote count:

Im using QTCreator and I have this structure:

typedef struct
{
     QString i;
} stBookMark;

These are some of the includes:

...
#include <QFile>
#include <QJsonArray>
#include <QJsonDocument>
#include <QVariantList>
#include <QVariant>
#include <QMetaType>

And I also added this:

Q_DECLARE_METATYPE(stBookMark)

The problem is somewhere here:

stBookMark x;
x.i = "Hello";

QVariant c;
c.setValue(x);

QVariantList a;
a.append(c);
a.append(0);
a.append(-119);

qDebug()<<a;

QJsonArray list = QJsonArray::fromVariantList(a);
QJsonDocument saveDoc(list);

And the output .json file here:

[
    null,
    0,
    -119
 ]
