Using a repeater to draw lines from a model?



  • 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)
            }
            }
        }
