QML SequentialAnimation Element

Detailed Description

The SequentialAnimation and ParallelAnimation elements 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 1.0

 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 element, a SequentialAnimation can be applied in a number of ways, including transitions, behaviors and property value sources. The QML Animation and Transitions documentation shows a variety of methods for creating animations.

Note: 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.
