详细说明
SequentialAnimation 和ParallelAnimation类型允许同时运行多个动画。在SequentialAnimation 中定义的动画会依次运行，而在ParallelAnimation中定义的动画则会同时运行。
以下动画示例并行运行两个数值动画。Rectangle 通过同时对x 和y 属性进行动画处理，移动到 (50,50) 位置。
import QtQuick
Rectangle {
id: rect
width: 100; height: 100
color: "red"
ParallelAnimation {
running: true
NumberAnimation { target: rect; property: "x"; to: 50; duration: 1000 }
NumberAnimation { target: rect; property: "y"; to: 50; duration: 1000 }
}
}与其他动画类型一样，ParallelAnimation可以通过多种方式应用，包括过渡、行为和属性值来源。 Qt Quick 文档中的“动画与过渡”部分展示了创建动画的多种方法。
注意：一旦 动画被归入SequentialAnimation 或ParallelAnimation中，就无法单独启动或停止；必须将SequentialAnimation 或ParallelAnimation作为整体进行启动和停止。
