Transitions shows animated transitions when showing or hiding items in a positioner. It consists of a scene populated with items in a variety of positioners: Column, Row, Grid, and Flow. Each positioner has animations described as Transitions.

move: Transition {
    NumberAnimation { properties: "x,y"; easing.type: Easing.OutBounce }

The move transition specifies how items inside a positioner will animate when they are displaced by the appearance or disappearance of other items.

add: Transition {
    NumberAnimation { properties: "x,y"; easing.type: Easing.OutBounce }

The add transition specifies how items will appear when they are added to a positioner.

populate: Transition {
    NumberAnimation { properties: "x,y"; from: 200; duration: 100; easing.type: Easing.OutBounce }

The populate transition specifies how items will appear when their parent positioner is first created.

Attached Properties

Attached Properties shows how the Positioner attached property can be used to determine where an item is within a positioner.

Rectangle {
    id: green
    color: "#80c342"
    width: 100 * page.ratio
    height: 100 * page.ratio

    Text {
      anchors.left: parent.right
      anchors.leftMargin: 20
      anchors.verticalCenter: parent.verticalCenter
      text: "Index: " + parent.Positioner.index
          + (parent.Positioner.isFirstItem ? " (First)" : "")
          + (parent.Positioner.isLastItem ? " (Last)" : "")

    // When mouse is clicked, display the values of the positioner
    MouseArea {
        anchors.fill: parent
        onClicked: column.showInfo(green.Positioner)
