The QDeclarativeView class provides a widget for displaying a Qt Declarative user interface.
QDeclarativeItem objects can be placed on a standard QGraphicsScene and displayed with QGraphicsView. QDeclarativeView is a QGraphicsView subclass provided as a convenience for displaying QML files, and connecting between QML and C++ Qt objects.
QDeclarativeView provides:
Typical usage:
Since QDeclarativeView is a QWidget-based class, it can be used to display QML interfaces within QWidget-based GUI applications that do not use the Graphics View framework.
To receive errors related to loading and executing QML with QDeclarativeView, you can connect to the statusChanged() signal and monitor for QDeclarativeView::Error. The errors are available via QDeclarativeView::errors().
If you're using your own QGraphicsScene-based scene with QDeclarativeView, remember to enable scene's sticky focus mode and to set itemIndexMethod to QGraphicsScene::NoIndex.

whether the view should resize the canvas contents
If this property is set to SizeViewToRootObject (the default), the view resizes with the root item in the QML.
If this property is set to SizeRootObjectToView, the view will automatically resize the root item.
Regardless of this property, the sizeHint of the view is the initial size of the root item. Note though that since QML may load dynamically, that size may change.
