The RotationAnimator type animates the rotation of an Item. 更多...
import 语句: | import QtQuick |
继承: | Animator |
Animator types are different from normal Animation types. When using an Animator, the animation can be run in the render thread and the property value will jump to the end when the animation is complete.
值 Item::rotation is updated after the animation has finished.
The following snippet shows how to use a RotationAnimator together with a Rectangle item.
Rectangle { id: rotatingBox width: 50 height: 50 color: "lightsteelblue" RotationAnimator { target: rotatingBox; from: 0; to: 360; duration: 1000 running: true } }
It is also possible to use the
on
keyword to tie the RotationAnimator directly to the
rotation
property of an Item instance.
Rectangle { width: 50 height: 50 color: "lightsteelblue" RotationAnimator on rotation { from: 0; to: 360; duration: 1000 } }

direction : enumeration |
This property holds the direction of the rotation.
Possible values are:
常量 | 描述 |
---|---|
RotationAnimator.Numerical
|
(default) Rotate by linearly interpolating between the two numbers. A rotation from 10 to 350 will rotate 340 degrees clockwise. |
RotationAnimator.Clockwise
|
Rotate clockwise between the two values |
RotationAnimator.Counterclockwise
|
Rotate counterclockwise between the two values |
RotationAnimator.Shortest
|
Rotate in the direction that produces the shortest animation path. A rotation from 10 to 350 will rotate 20 degrees counterclockwise. |
