详细说明

Animator 类型不同于普通的动画类型。使用 Animator 时，动画可以在呈现线程中运行，当动画完成时，属性值将跳转到末尾。

Item::scale 的值会在动画结束后更新。

下面的代码段展示了如何将 ScaleAnimator 与矩形项结合使用。

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

也可以使用on 关键字将 ScaleAnimator 直接绑定到项目实例上。

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