Oussou

Hello, I would like to display the contents of my json file in QML, can someone help me ? please

here is the content of the json file :
//test.json

{
"classe": "2btssn",
"active": true,
"nb": 3,
"etudiants": [
{ "prénom": "John", "nom": "Doe", "age": 19 },
{ "prénom": "Jane", "nom": "Doe" , "age": 19 },
{ "prénom": "Robert", "nom": "Smith" , "age": 18 }
]
}

//here is the content of my main.cpp file

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QString>
#include <QJsonDocument>
#include <QFile>
#include <QQmlContext>

#include <QJsonObject>
#include <QJsonArray>

int main(int argc, char *argv[])
{
#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
#endif

QGuiApplication app(argc, argv);

QQmlApplicationEngine engine;
QFile fichierJSON("test.json");
if (fichierJSON.open(QFile::ReadOnly | QFile::Text))
{
    // lecture les données du fichier JSON
    QString donnees = fichierJSON.readAll();

    fichierJSON.close();
}


const QUrl url(QStringLiteral("qrc:/main.qml"));
QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                 &app, [url](QObject *obj, const QUrl &objUrl) {
    if (!obj && url == objUrl)
        QCoreApplication::exit(-1);
}, Qt::QueuedConnection);

engine.load(url);

return app.exec();

}

Hi,

If it's only to dump on the application output using qDebug would be enough.
