Constructor & Destructor Documentation

◆ QQuickParallelAnimation()

QQuickParallelAnimation::QQuickParallelAnimation ( QObject * parent = nullptr)

\qmltype ParallelAnimation \instantiates QQuickParallelAnimation \inqmlmodule QtQuick\inherits Animation

Enables animations to be run in parallel.

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

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 }
}
}

Like any other animation type, a ParallelAnimation can be applied in a number of ways, including transitions, behaviors and property value sources. The \l {Animation and Transitions in Qt Quick} 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.
