Detailed Description

The Particles object generates and moves particles.

Since

4.7

Particles are available in the <b>Qt.labs.particles 1.0</b> module.
\e {Elements in the Qt.labs module are not guaranteed to remain compatible
in future versions.}

This element provides preliminary support for particles in QML,
and may be heavily changed or removed in later versions.

The particles created by this object cannot be dealt with
directly, they can only be controlled through the parameters of
the Particles object. The particles are all the same pixmap,
specified by the user.

The particles are painted relative to the parent of the Particles
object.  Moving the Particles object will not move the particles
already emitted.

The below example creates two differently behaving particle
sources.  The top one has particles falling from the top like
snow, the lower one has particles expelled up like a fountain.

import QtQuick 1.0
import Qt.labs.particles 1.0

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
        }
    }
    Particles {
        y: 300
        x: 120
        width: 1
        height: 1
        source: "star.png"
        lifeSpan: 5000
        count: 200
        angle: 270
        angleDeviation: 45
        velocity: 50
        velocityDeviation: 30
        ParticleMotionGravity {
            yattractor: 1000
            xattractor: 0
            acceleration: 25
        }
    }
}
