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 }
          }
      }
  }
