Since your other thread suggests that you will get multiple "rows" of these three values, the best way to present these rows of values to QML/QtQuick is a list model.

The ClientService object needs to notify the model about new incoming data, maybe via signal.

Easiest way is probably to do all the object creation and connecting on the C++ side and simply expose the fully working model to QML via QQmlContext::setContextProperty() on the engine's rootContext().
