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.
