QT_BEGIN_NAMESPACE QQuickParticleEmitter::QQuickParticleEmitter ( QQuickItem * parent = nullptr )

explicit

Emits logical particles.

\qmltype Emitter

! \instantiates QQuickParticleEmitter \inqmlmodule QtQuick.Particles

This element emits logical particles into the ParticleSystem, with the given starting attributes.

Note that logical particles are not automatically rendered, you will need to have one or more ParticlePainter elements visualizing them.

Note that the given starting attributes can be modified at any point in the particle's lifetime by any Affector element in the same ParticleSystem. This includes attributes like lifespan.

\qmlproperty ParticleSystem QtQuick.Particles::Emitter::system

This is the Particle system that the Emitter will emit into. This can be omitted if the Emitter is a direct child of the ParticleSystem

\qmlproperty string QtQuick.Particles::Emitter::group

This is the logical particle group which it will emit into.

Default value is "" (empty string).

\qmlproperty Shape QtQuick.Particles::Emitter::shape

This shape is applied with the size of the Emitter. Particles will be emitted randomly from any area covered by the shape.

The default shape is a filled in rectangle, which corresponds to the full bounding box of the Emitter.

\qmlproperty bool QtQuick.Particles::Emitter::enabled

If set to false, the emitter will cease emissions until it is set to true.

Default value is true.

\qmlproperty real QtQuick.Particles::Emitter::emitRate

Number of particles emitted per second.

Default value is 10 particles per second.

\qmlproperty int QtQuick.Particles::Emitter::lifeSpan

The time in milliseconds each emitted particle should last for.

If you do not want particles to automatically die after a time, for example if you wish to dispose of them manually, set lifeSpan to Emitter.InfiniteLife.

lifeSpans greater than or equal to 600000 (10 minutes) will be treated as infinite. Particles with lifeSpans less than or equal to 0 will start out dead.

Default value is 1000 (one second).

\qmlproperty int QtQuick.Particles::Emitter::lifeSpanVariation

Particle lifespans will vary by up to this much in either direction.

Default value is 0.

\qmlproperty int QtQuick.Particles::Emitter::maximumEmitted

The maximum number of particles at a time that this emitter will have alive.

This can be set as a performance optimization (when using burst and pulse) or to stagger emissions.

If this is set to a number below zero, then there is no maximum limit on the number of particles this emitter can have alive.

The default value is -1.

\qmlproperty int QtQuick.Particles::Emitter::startTime

If this value is set when the emitter is loaded, then it will emit particles from the past, up to startTime milliseconds ago. These will simulate as if they were emitted then, but will not have any affectors applied to them. Affectors will take effect from the present time.

\qmlproperty real QtQuick.Particles::Emitter::size

The size in pixels of the particles at the start of their life.

Default value is 16.

\qmlproperty real QtQuick.Particles::Emitter::endSize

The size in pixels of the particles at the end of their life. Size will be linearly interpolated during the life of the particle from this value and size. If endSize is -1, then the size of the particle will remain constant at the starting size.

Default value is -1.

\qmlproperty real QtQuick.Particles::Emitter::sizeVariation

The size of a particle can vary by this much up or down from size/endSize. The same random addition is made to both size and endSize for a single particle.

Default value is 0.

\qmlproperty StochasticDirection QtQuick.Particles::Emitter::velocity

The starting velocity of the particles emitted.

\qmlproperty StochasticDirection QtQuick.Particles::Emitter::acceleration

The starting acceleraton of the particles emitted.

\qmlproperty qreal QtQuick.Particles::Emitter::velocityFromMovement

If this value is non-zero, then any movement of the emitter will provide additional starting velocity to the particles based on the movement. The additional vector will be the same angle as the emitter's movement, with a magnitude that is the magnitude of the emitters movement multiplied by velocityFromMovement.

Default value is 0.

\qmlsignal QtQuick.Particles::Emitter::emitParticles(Array particles)

This signal is emitted when particles are emitted. particles is a JavaScript array of Particle objects. You can modify particle attributes directly within the handler.

Note: JavaScript is slower to execute, so it is not recommended to use this in high-volume particle systems.

\qmlmethod QtQuick.Particles::Emitter::burst(int count)

Emits a number of particles, specified by count, from this emitter immediately.

\qmlmethod QtQuick.Particles::Emitter::burst(int count, int x, int y)

Emits a number of particles, specified by count, from this emitter immediately. The particles are emitted as if the Emitter was positioned at ({x}, {y}) but all other properties are the same.

\qmlmethod QtQuick.Particles::Emitter::pulse(int duration)

If the emitter is not enabled, enables it for a specified duration (in milliseconds) and then switches it back off.
