Properly set my main.cpp

DavidM29

Hello,

I do have a QML app which work fine. But at starts I have a warning message telling me this :

QQuickView does not support using windows as a root item. 
If you wish to create your root window from QML, consider using QQmlApplicationEngine instead.

The message is quite clear about what is wrong but I dont know how to correct it properly.

Here is my main.cpp

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

    QGuiApplication app(argc, argv);

    qmlRegisterType<RadialBar>("CustomControls", 1, 0, "RadialBar");

    QQuickView *view = new QQuickView();  //This is causing the warning message but I don't know how to replace it and still be able to use the contextProperty
    KeyBoardHelper *keyboard = new KeyBoardHelper(view);
    qmlRegisterUncreatableType<KeyBoardHelper>("Keyboard",1,0,"KeyBoardHelper","");
    view->rootContext()->setContextProperty("kb",keyboard);
    view->setSource(QStringLiteral("qrc:/main.qml"));

    return app.exec();
}

Does anybody know what kind of change I should make here and eventually give me some advice/good practice for the main.cpp

Thank you in advance

Hi,

The solution is provided in the error message: use QQmlApplicationEngine in place of QQuickView.
