Question

i made animations in transition. so if state change, so the transition is emitted. here is the sequential animation that i made.

SequentialAnimation{
            PropertyAnimation{
                properties: "width"
                duration: 300
            }
            PropertyAnimation{
                properties: "x"
                duration: 500
            }
            Component.onCompleted: {
                var idx = Math.ceil(Math.random()*2);
                if(idx===0){
                    anim0.running = true
                    anim1.running = false
                }
                else {
                    anim1.running = true
                    anim0.running = false
                }
                console.log("haha");
            }
        }

        SequentialAnimation{
            id: anim0
            running: false
            NumberAnimation{
                running: anim0.running
                properties: "x"
                to: 300
                duration: 500
            }
            Component.onCompleted: console.log("anim0");
        }
        SequentialAnimation{
            id: anim1
            running: false
            NumberAnimation{
                running: anim1.running
                properties: "x"
                to: -300
                duration: 500
            }
            Component.onCompleted: console.log("anim1");
        }

Ignore the JavaScript first on Component.onCompleted signal.
SequencialAnimation with id: anim1 and anim0 keep running although i had already set running attribute to false…

Setting the running property of an Animation item to false, will not prevent the animation start. It will just stop it if it’s currently runnging.

If you don’t want an animation to be started in a transition, then just don’t put it inside a transition.
You can always define your custom Animation Item outside the Transition, and trigger it when you want to by using the animationId.start() function.

For detailed informations see the documentation page.
