Allows animations to be run sequentially. 更多...

The SequentialAnimation and ParallelAnimation types allow multiple animations to be run together. Animations defined in a SequentialAnimation are run one after the other, while animations defined in a ParallelAnimation are run at the same time.
The following example runs two number animations in a sequence. The
Rectangle
animates to a
x
position of 50, then to a
y
position of 50.
import QtQuick 2.0 Rectangle { id: rect width: 100; height: 100 color: "red" SequentialAnimation { running: true NumberAnimation { target: rect; property: "x"; to: 50; duration: 1000 } NumberAnimation { target: rect; property: "y"; to: 50; duration: 1000 } } }
Animations defined within a Transition are automatically run in parallel, so SequentialAnimation can be used to enclose the animations in a Transition if this is the preferred behavior.
Like any other animation type, a SequentialAnimation can be applied in a number of ways, including transitions, behaviors and property value sources. The Qt Quick 中的动画和过渡 documentation shows a variety of methods for creating animations.
注意： Once an animation has been grouped into a SequentialAnimation or ParallelAnimation , it cannot be individually started and stopped; the SequentialAnimation or ParallelAnimation must be started and stopped as a group.
