Delayed 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.
