详细描述

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::scale is updated after the animation has finished.

The following snippet shows how to use a ScaleAnimator together with a Rectangle item.

Rectangle {
    id: scalingBox
    width: 50
    height: 50
    color: "lightsteelblue"
    ScaleAnimator {
        target: scalingBox;
        from: 0.5;
        to: 1;
        duration: 1000
        running: true
    }
}
					

It is also possible to use the on keyword to tie the ScaleAnimator directly to an Item instance.

Rectangle {
    width: 50
    height: 50
    color: "lightsteelblue"
    ScaleAnimator on scale {
        from: 0.5;
        to: 1;
        duration: 1000
    }
}
