Unsolved Animation: what is better gpu wise?

[JulienD]

Hello,

What is better, as far as gpu is involved?
This code is silly ans useless but makes the point.

1st solution:

Item{
   x: 0
   ...
   MouseArea{
       anchors.fill: parent
       onClicked:{
          another_item.x = 0
   }
}

2nd:

Item{
id: my_item
   x: 0
  state: "init"
   ...
   MouseArea{
       anchors.fill: parent
       onClicked:{
          another_item.state = "move_it"
   }
}


    states: [
        State {
            name: "init"
            PropertyChanges { target: another_item; x: 0}
        },
        State {
            name: "move_it"
            PropertyChanges { target: another_item; x: somewhere}
        }
    ]

The question is:
Is it better to set things in javascript (blah.x = 0) or by states (blash.state = "new_state") for performance and fluidity?

My tests reveal no difference but I may be wrong.
