+    \qmlclass SmoothedFollow QDeclarativeSmoothedFollow
+    \since 4.7
+    \inherits NumberAnimation
+    \brief The SmoothedFollow element allows a property to smoothly track a value.
+
+    The SmoothedFollow animates a property's value to a set target value
+    using an ease in/out quad easing curve.  If the animation is restarted
+    with a different target value, the easing curves used to animate to the old
+    and the new target values are smoothly spliced together to avoid any obvious
+    visual glitches by maintaining the current velocity.
+
+    The property animation is configured by setting the velocity at which the
+    animation should occur, or the duration that the animation should take.
+    If both a velocity and a duration are specified, the one that results in
+    the quickest animation is chosen for each change in the target value.
+
+    For example, animating from 0 to 800 will take 4 seconds if a velocity
+    of 200 is set, will take 8 seconds with a duration of 8000 set, and will
+    take 4 seconds with both a velocity of 200 and a duration of 8000 set.
+    Animating from 0 to 20000 will take 10 seconds if a velocity of 200 is set,
+    will take 8 seconds with a duration of 8000 set, and will take 8 seconds
+    with both a velocity of 200 and a duration of 8000 set.
+
+    The follow example shows one rectangle tracking the position of another.
+\code
+import Qt 4.6
+
+Rectangle {
+    width: 800; height: 600; color: "blue"
+
+    Rectangle {
+        color: "green"
+        width: 60; height: 60;
+        SmoothedFollow on x { to: rect1.x - 5; velocity: 200 }
+        SmoothedFollow on y { to: rect1.y - 5; velocity: 200 }
+    }
+
+    Rectangle {
+        id: rect1
+        color: "red"
+        width: 50; height: 50;
+    }
+
+    focus: true
+    Keys.onRightPressed: rect1.x = rect1.x + 100
+    Keys.onLeftPressed: rect1.x = rect1.x - 100
+    Keys.onUpPressed: rect1.y = rect1.y - 100
+    Keys.onDownPressed: rect1.y = rect1.y + 100
+}
+\endcode
+
+    The default velocity of SmoothedFollow is 200 units/second.  Note that if the range of the
+    value being animated is small, then the velocity will need to be adjusted
+    appropriately.  For example, the opacity of an item ranges from 0 - 1.0.
+    To enable a smooth animation in this range the velocity will need to be
+    set to a value such as 0.5 units/second.  Animating from 0 to 1.0 with a velocity
+    of 0.5 will take 2000 ms to complete.
