<snip, detect parent/child changes from QML in C++> Martin spaketh:

Related question: Now that I'm in the QGraphicsItem world, which is *not* a QObject with properties, how does QML expose attributes (since those are *all* properties based)? For example, the QGraphicsItem::boundingRect() is always (0,0,-1,-1), even though the referenced QML component *has* width and height. Similarly, the QGraphicsItem::opaqueArea()::boundingRect() is always (0,0,0,0). Does the QGraphicsItem have *any* opinion about or state from attributes in the QML element? (e.g., what attributes can I trust in the QGraphicsItem as being those used by the QML element?) What is the intended mechanism by which I interrogate the QGraphicsItem? (Is the expectation that the user will merely attempt to downcast to QGraphicsObject or QDeclarativeItem, handling the scenarios where it is not that type?) For examle, I *assume* that the MouseArea will trigger child notification, but it is not a QDeclarativeItem. In contrast, a Rectangle{} or Text{} trigger child notification, and "happen to be" QDeclarativeItem instances. Thanks! --charley
