The ParticleMotionWander object moves particles in a somewhat random fashion. More...

This element was introduced in Qt 4.7.


Detailed Description

The particles will continue roughly in the original direction, however will randomly drift to each side.

The code below produces an effect similar to falling snow.

 Rectangle {
     width: 240
     height: 320
     color: "black"

     Particles {
         y: 0
         width: parent.width
         height: 30
         source: "star.png"
         lifeSpan: 5000
         count: 50
         angle: 70
         angleDeviation: 36
         velocity: 30
         velocityDeviation: 10
         ParticleMotionWander {
             xvariance: 30
             pace: 100
