Afficher les processus : 'QVariant::QVariant(void*)' is private within this context

Bonjour,

Etant debutant, je m' entraine en faisant une petite appli en qml pour monitorer les ressources de mon gnu/linux, j' ai un petit probleme lors de la compilation, manque de connaissances.

main.cpp

    ProcessusInfo execProcessus;
 
 
    QmlApplicationViewer viewer;
    viewer.rootContext()->setContextProperty("loadcpu", &execProcess);
    viewer.rootContext()->setContextProperty("loadmem", &execMem);
 
 
    viewer.rootContext()->setContextProperty("loadproc", &execProcessus);   // Probleme
 
 
    viewer.setOrientation(QmlApplicationViewer::ScreenOrientationAuto);
    viewer.setMainQmlFile(QLatin1String("qml/testqml/main.qml"));
    viewer.showExpanded();

provient de cette ligne dans le main.cpp

viewer.rootContext()->setContextProperty("loadproc", &execProcessus);

malheureusement je ne sais pas par quoi je dois remplacer:

rootContext()->setContextProperty

pour imprimer les valeurs dans qml

Pourriez-vous m' aiguiller?
