## Detailed Description

An object of type Positioner is attached to the top-level child item within a Column, Row, Flow or Grid. It provides properties that allow a child item to determine where it exists within the layout of its parent Column, Row, Flow or Grid.

For example, below is a Grid with 16 child rectangles, as created through a Repeater. Each Rectangle displays its index in the Grid using Positioner.index, and the first item is colored differently by taking Positioner.isFirstItem into account:

     Grid {
         Repeater {
             model: 16

             Rectangle {
                 id: rect
                 width: 30; height: 30
                 border.width: 1
                 color: Positioner.isFirstItem ? "yellow" : "lightsteelblue"

                 Text { text: rect.Positioner.index }
             }
         }
     }
