Using a repeater to draw lines from a model?

[maxwell31]

Hi,

I am working on a plotting library. Right now I need to draw lines for certain events. I have a QQmlListProperty which holds the position of the lines on the c++ side. I have a Event.qml object, which is drawing the line (a thin rectangle). I am wondering on what is the best approach to draw the events. I should also mention, that it should be possible to drag the rectangles to new positions and the changes should be written back to the c++ model.

Does it make sense to use a repeater? Or should I create the events like this:

    function drawEvents() {
        for(var i=0; i<eventList.length;i++) {
        var component = Qt.createComponent("Event.qml");
        if(component.status == Component.Ready) {
            var event = component.createObject(root)
            event.time =eventList[i].time
            event.name=eventList[i].name
            event.setX()
            eventObjects.push(event)
        }
        }
    }
