+    \qmlclass LayoutItem QDeclarativeLayoutItem
+    \since 4.7
+    \brief The LayoutItem element allows you to place your declarative UI elements inside a classical Qt layout.
+
+    LayoutItem is a variant of Item with a couple of additional properties. These properties provide the size hints
+    needed for items to work in conjunction with Qt Layouts. The Qt Layout 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 the properties merely expose the QGraphicsLayoutItem functionality to QML.
+    See the QGraphicsLayoutItem documentation for further details.
