-\title Integrating QML Code with Existing Qt UI Code
-\brief applications with QML and Qt code
-
-There are a number of ways to integrate QML into QWidget-based UI applications,
-depending on the characteristics of your existing UI code.
-
-
-\section1 Integrating with a \l{QWidget}-based UI
-
-If you have an existing QWidget-based UI, QML widgets can be integrated into
-it using QQuickView. QQuickView is a subclass of QWidget so you
-can add it to your user interface like any other QWidget. Use
-QQuickView::setSource() to load a QML file into the view, then add the
-view to your UI:
-
-\code
-QQuickView *qmlView = new QQuickView;
-qmlView->setSource(QUrl::fromLocalFile("myqml.qml"));
-
-QWidget *widget = myExistingWidget();
-QVBoxLayout *layout = new QVBoxLayout(widget);
-layout->addWidget(qmlView);
-\endcode
-
-The one drawback to this approach is that QQuickView is slower to initialize
-and uses more memory than a QWidget, and creating large numbers of QQuickView
-objects may lead to performance degradation. If this is the case, it may be
-better to rewrite your widgets in QML, and load the widgets from a main QML widget
-instead of using QQuickView.
-
-Keep in mind that QWidgets were designed for a different type of user interface
-than QML, so it is not always a good idea to port a QWidget-based application to
-QML. QWidgets are a better choice if your UI is comprised of a small number of
-complex and static elements, and QML is a better choice if your UI is comprised of a large number
-of simple and dynamic elements.
-
-
-\section1 Integrating with a QGraphicsView-based UI
-
-\section2 Adding QML widgets to a QGraphicsScene
-
-If you have an existing UI based on the \l{Graphics View Framework},
-you can integrate QML widgets directly into your QGraphicsScene. Use
-QQmlComponent to create a QGraphicsObject from a QML file, and
-place the graphics object into your scene using \l{QGraphicsScene::addItem()}, or
-reparent it to an item already in the \l{QGraphicsScene}.
-
-For example:
-
-\code
-QGraphicsScene* scene = myExistingGraphicsScene();
-QQmlEngine *engine = new QQmlEngine;
-QQmlComponent component(engine, QUrl::fromLocalFile("myqml.qml"));
-QGraphicsObject *object =
-    qobject_cast<QGraphicsObject *>(component.create());
-scene->addItem(object);
-\endcode
-
-The following QGraphicsView options are recommended for optimal performance
-of QML UIs:
-
-\list
-\li QGraphicsView::setOptimizationFlags(QGraphicsView::DontSavePainterState)
-\li QGraphicsView::setViewportUpdateMode(QGraphicsView::BoundingRectViewportUpdate)
-\li QGraphicsScene::setItemIndexMethod(QGraphicsScene::NoIndex)
-\endlist
-
-\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. See the \l {declarative-cppextensions-qgraphicslayouts.html}{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.
-
-To expose your existing QGraphicsWidget classes to QML, use \l {qmlRegisterType()}.
-See \l{Extending QML with C++} for further information on how to use C++ types
-in QML.
