OpacityAnimator QML Type

  • Import Statement: import QtQuick

  • Since:: Qt 5.2

  • Inherits:: Animator

  • Group: OpacityAnimator is part of qtquick-transitions-animations

Detailed Description

Animator types are different from normal Animation types. When using an Animator, the animation can be run in the render thread and the property value will jump to the end when the animation is complete.

The value of Item::opacity is updated after the animation has finished.

The following snippet shows how to use a OpacityAnimator together with a Rectangle item.

 
Sélectionnez
Rectangle {
    id: opacityBox
    width: 50
    height: 50
    color: "lightsteelblue"
    OpacityAnimator {
        target: opacityBox;
        from: 0;
        to: 1;
        duration: 1000
        running: true
    }
}

It is also possible to use the on keyword to tie the OpacityAnimator directly to an Item instance.

 
Sélectionnez
Rectangle {
    width: 50
    height: 50
    color: "lightsteelblue"
    OpacityAnimator on opacity{
        from: 0;
        to: 1;
        duration: 1000
    }
}
