The ParallelAnimation element allows animations to be run in parallel. More...

This element was introduced in Qt 4.7.

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 animation runs two number animations in parallel. The Rectangle moves to (50,50) by animating its x and y properties at the same time.

 import QtQuick 1.0

 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 }

Like any other animation element, a ParallelAnimation 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.
