+    \qmltype ScrollView
+    \inqmlmodule QtQuick.Controls
+    \since  5.1
+    \ingroup views
+    \brief Provides a scrolling view within another Item.
+
+    A ScrollView can be used either to replace a \l Flickable or decorate an
+    existing \l Flickable. Depending on the platform, it will add scroll bars and
+    a content frame.
+
+    Only one Item can be a direct child of the ScrollView and the child is implicitly anchored
+    to fill the scroll view.
+
+    Example:
+    \code
+    ScrollView {
+        Image { source: "largeImage.png" }
+    }
+    \endcode
+
+    In the previous example the Image item will implicitly get scroll behavior as if it was
+    used within a \l Flickable. The width and height of the child item will be used to
+    define the size of the content area.
+
+    Example:
+    \code
+    ScrollView {
+        ListView {
+            ...
+        }
+    }
+    \endcode
+
+    In this case the content size of the ScrollView will simply mirror that of its contained
+    \l flickableItem.
+
+    You can create a custom appearance for a ScrollView by
+    assigning a \l {QtQuick.Controls.Styles::ScrollViewStyle}{ScrollViewStyle}.
