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:
Sélectionnez
Grid {
Repeater {
model: 16
Rectangle {
id: rect
width: 30; height: 30
border.width: 1
color: Positioner.isFirstItem ? "yellow" : "lightsteelblue"
Text { text: rect.Positioner.index }
}
}
}
