Need help passing data to qml

[brasscs]

hey thanks for the code but it still does not work. this is what i am using

.cpp

using namespace Ui;
    QQmlEngine engine;
    QQmlComponent component(&engine, "/home/user/projects-qt5/test_qml/MyItem.qml");
    QObject *object = component.create();
    QVariant returnedValue;
 
    MyStruct s;
    s.i=12;
    s.name="Hello QML";
    QVariantMap map;
    map["i"] = s.i;
    map["name"] = s.name;
 
    QVariant v = map;
    QMetaObject::invokeMethod(object, "myQmlFunction",
                                  Q_RETURN_ARG(QVariant, returnedValue),
                                  Q_ARG(QVariant,v));

using namespace Ui;
    QQmlEngine engine;
    QQmlComponent component(&engine, "/home/user/projects-qt5/test_qml/MyItem.qml");
    QObject *object = component.create();
    QVariant returnedValue;

    MyStruct s;
    s.i=12;
    s.name="Hello QML";
    QVariantMap map;
    map["i"] = s.i;
    map["name"] = s.name;

    QVariant v = map;
    QMetaObject::invokeMethod(object, "myQmlFunction",
                                  Q_RETURN_ARG(QVariant, returnedValue),
                                  Q_ARG(QVariant,v));
