javascript - QtQuick2 - QML - create infinite moving line animation -


does know how implement linear animation, example in progress bars, few of lines moving infinite in bar left right or other way? i'm going use qtquick2 primitives , without additional c++ components, glad see answers can fit requirements. also, know how set infinite loop animation, actual question how moves row of rectangles/lines letf right in infinity loop, can't imagine approach that.

something that?

rectangle {     width: 400     height: 30     anchors.centerin: parent     border.color: "grey"     border.width: 1     clip: true      rectangle {         id: runner         property double percent: 0.2         width: parent.width * percent         height: parent.height         color: "orange"         numberanimation on x { from: runner.width * (-1); to: 400; duration: 2000; loops: animation.infinite }     } }
