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::opacity is updated after the animation has finished.
The following snippet shows how to use a OpacityAnimator together with a Rectangle item.
Rectangle { id: opacityBox width: 50 height: 50 color: "lightsteelblue" OpacityAnimator { target: opacityBox; from: 0; to: 1; duration: 1000 running: true } }
It is also possible to use the
on
keyword to tie the OpacityAnimator directly to an Item instance.
Rectangle { width: 50 height: 50 color: "lightsteelblue" OpacityAnimator on opacity{ from: 0; to: 1; duration: 1000 } }
