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.
