    Description

      Minimal example:

      main.cpp
      #include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QDebug>

class Test : public QObject
{
    Q_OBJECT
    Q_PROPERTY(int foo READ foo CONSTANT FINAL)

public:
    int foo() const { return 1; }

    Test() {}
};

int main(int argc, char *argv[])
{
#if defined(Q_OS_WIN)
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
#endif

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;

    qmlRegisterType<Test>("App", 1, 0, "Test");

    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
    if (engine.rootObjects().isEmpty())
        return -1;

    return app.exec();
}

#include "main.moc"
      main.qml
      import QtQuick 2.9
import QtQuick.Window 2.0

import App 1.0

Window {
    width: 600
    height: 600
    title: qsTr("Hello World")
    visible: true

    Test {
        objectName: foo ? "bar" : "baz"
    }
}
