+    \brief The Flickable item provides a surface that can be "flicked".
+    \inherits Item
+
+    Flickable places its children on a surface that can be dragged and flicked.
+
+    \code
+    Flickable {
+        width: 200; height: 200
+        contentWidth: image.width; contentHeight: image.height
+
+        Image { id: image; source: "bigImage.png" }
+    }
+    \endcode
+
+    \image flickable.gif
+
+    Flickable does not automatically clip its contents. If
+    it is not full-screen it is likely that \l {Item::clip}{clip} should be set
+    to \c true.
+
+    \note Due to an implementation detail, items placed inside a Flickable cannot anchor to it by
+    \c id. Use \c parent instead.
