+ \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.
