		QObject *	parent = `nullptr`
	)

protected

\qmltype Animator \instantiates QQuickAnimator \inqmlmodule QtQuick

Since: 5.2

\inherits Animation

Is the base of all QML animators.

Animator types are a special type of animation which operate directly on Qt Quick's scene graph, rather than the QML objects and their properties like regular Animation types do. This has the benefit that Animator based animations can animate on the \l {Threaded Render Loop ('threaded')}{scene graph's rendering thread} even when the UI thread is blocked.

The value of the QML property will be updated after the animation has finished. The property is not updated while the animation is running.

The Animator types can be used just like any other Animation type.

Rectangle {
    id: mixBox
    width: 50
    height: 50
    ParallelAnimation {
        ColorAnimation {
            target: mixBox
            property: "color"
            from: "forestgreen"
            to: "lightsteelblue";
            duration: 1000
        }
        ScaleAnimator {
            target: mixBox
            from: 2
            to: 1
            duration: 1000
        }
        running: true
    }
}

If all sub-animations of ParallelAnimation and SequentialAnimation are Animator types, the ParallelAnimation and SequentialAnimation will also be treated as an Animator and be run on the scene graph's rendering thread when possible.

The Animator types can be used for animations during transitions, but they do not support the \l {Transition::reversible}{reversible} property.

The Animator type cannot be used directly in a QML file. It exists to provide a set of common properties and methods, available across all the other animator types that inherit from it. Attempting to use the Animator type directly will result in an error.
