Note that if you just wanted the animation to follow directly after the previous one you could use SequentialAnimation. This example is rather to show arbitrary delays in animations.

Ever want the user to click something and then play out a series of delayed events? For example, opening a list and closing it again?

The following example starts with a red circle. When the user clicks on the circle, it animates in to a rectangle and triggers a timer. Once the timer triggers, it animates the rectangle back in to a circle again.

import QtQuick 1.0

Rectangle {
 property int time: 800
 property int size: 300
 width: size; height: size; radius: size
 color: "red"
 Behavior on radius { NumberAnimation { duration: time } }
 Timer {
  id: reset
  interval: time;
  onTriggered: parent.radius = size
  }

 MouseArea {
  anchors.fill: parent
  onClicked: {
   parent.radius = 0;
   reset.start()
  }
 }
}

Note that if you just wanted the animation to follow directly after the previous one you could use SequentialAnimation. This example is rather to show arbitrary delays in animations.
