Final task upon program termination

[texasRanger]

Hello,

I was wondering if there is a way to run a final function call/ slot when a program terminates. I have a json file with data that is being updated and read from. When the program ends (user stops running program) I want to reset the data withing the file. Is there any type of signal slot that you be used right before before terminates?

Does you main.cpp look something like this?

#include <QGuiApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    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();
}

Then change the return statement to something like this:

auto ret = app.exec()

// your final code here
finalfunction();

return ret;
