 \section2 Loading QGraphicsWidget objects in QML
 
 An alternative approach is to expose your existing QGraphicsWidget objects to 
-QML and construct your scene in QML instead. To do this, you need to register
-any custom C++ types and create a plugin that registers the custom types
-so that they can be used from your QML file.
+QML and construct your scene in QML instead. See the \l {declarative/layouts/graphicsLayouts}{graphics layouts example}
+which shows how to expose Qt's graphics layout classes to QML in order
+to use QGraphicsWidget with classes like QGraphicsLinearLayout and QGraphicsGridLayout.
 
-Here is an example. Suppose you have two classes, \c RedSquare and \c BlueCircle,
-that both inherit from QGraphicsWidget:
-
-\c [graphicswidgets/redsquare.h]
-\snippet doc/src/snippets/declarative/graphicswidgets/redsquare.h 0
-
-\c [graphicswidgets/bluecircle.h]
-\snippet doc/src/snippets/declarative/graphicswidgets/bluecircle.h 0
-
-Then, create a plugin by subclassing QDeclarativeExtensionPlugin, and register the
-types by calling qmlRegisterType(). Also export the plugin with Q_EXPORT_PLUGIN2.
-
-\c [graphicswidgets/shapesplugin.cpp]
-\snippet doc/src/snippets/declarative/graphicswidgets/shapesplugin.cpp 0
-
-Now write a project file that creates the plugin:
-
-\c [graphicswidgets/graphicswidgets.pro]
-\quotefile doc/src/snippets/declarative/graphicswidgets/graphicswidgets.pro
-
-And add a \c qmldir file that includes the \c graphicswidgets plugin from the \c lib
-subdirectory (as defined in the project file):
-
-\c [graphicswidgets/qmldir]
-\quotefile doc/src/snippets/declarative/graphicswidgets/qmldir
-
-Now, we can write a QML file that uses the \c RedSquare and \c BlueCircle widgets.
-(As an example, we can also create \c QGraphicsWidget items if we import the \c Qt.widgets
-module.)
-
-\c [main.qml]
-\quotefile doc/src/snippets/declarative/graphicswidgets/main.qml
-
-Here is a screenshot of the result:
-
-\image declarative-integrating-graphicswidgets.png 
-
-
-Note this approach of creating your graphics objects from QML does not work
-with QGraphicsItems that are not QGraphicsObject-based, since they are not QObjects.
-
-See \l{Extending QML in C++} for further information on using C++ types.
+To expose your existing QGraphicsWidget classes to QML, use \l {qmlRegisterType()}.
+See \l{Extending QML in C++} for further information on using C++ types in QML.
