There are many ways to do that not sure which one is best, but I will share
what I generally do:


   1. When I want to integrate QML in a widget app, I generally use
   QQuickWIdget.
   2. For dialogs:
   - either I use a QDialog and I integrate the QQuickWidget as any other
      widget
      - or I implement a QuickDialog which is a subclass of QQuickView with
      some QDialog-like functions (exec(), accept(), etc.)
      3. I never use Window or ApplicationWindow QML types, because, as you
   have experienced, you get 2 windows: one from the QQuickView and a second
   one from the Window QML type.

course there are some exceptions.
Also, it is possible to replace QQuickWidget by a QQuickView combined with
QWidget::createWindowContainer().

I only use QQmlApplicationEngine and Window QML types when writing pure Qt
Quick applications.
