+ \qmlclass LayoutItem QDeclarativeLayoutItem
+ \ingroup qml-utility-elements
+ \since 4.7
+ \brief The LayoutItem element allows declarative UI elements to be placed inside Qt's Graphics View layouts.
+
+ LayoutItem is a variant of \l Item with additional size hint properties. These properties provide the size hints
+ necessary for items to work in conjunction with Qt \l{Graphics View Framework}{Graphics View} layout classes
+ such as QGraphicsLinearLayout and QGraphicsGridLayout. The Qt layout mechanisms will resize the LayoutItem as appropriate,
+ taking its size hints into account, and you can propagate this to the other elements in your UI via anchors and bindings.
+
+ This is a QGraphicsLayoutItem subclass, and its properties merely expose the QGraphicsLayoutItem functionality to QML.
+
+ The \l{declarative/cppextensions/qgraphicslayouts/layoutitem}{LayoutItem example}
+ demonstrates how a LayoutItem can be used within a \l{Graphics View Framework}{Graphics View}
+ scene.
