qt - Repeater access elements -

i have following repeater:

repeater{     id: raindropid     model: 200      delegate: rectangle {          x: math.floor(math.random() * windowid.width)         y: math.floor(math.random() * windowid.height)         property int mlayer: math.floor(math.random() * 4) + 1          property double myspeed: -2.0 * mlayer          width:5         height:5         color: "#3399ff"         radius: width*0.5     } } 

and have timer. want modify positions of elements repeater according own properties. how can access raindropid[index] timer?

thanks

use repeater's itemat() method:

import qtquick 2.4 import qtquick.window 2.2  window {     id: windowid     visible: true     width: 400     height: 400      repeater {         id: raindropid         model: 200          delegate: rectangle {             width:5             height:5             color: "#3399ff"             radius: width*0.5         }     }      timer {         running: true         interval: 1000         repeat: true         triggeredonstart: true         ontriggered: {             (var = 0; < raindropid.count; ++i) {                 raindropid.itemat(i).x = math.floor(math.random() * windowid.width);                 raindropid.itemat(i).y = math.floor(math.random() * windowid.height);             }         }     } } 

you might consider using qt quick particles create rain drops.
