50 \inqmlmodule QtQuick.Particles-
51 \brief Emits logical particles.-
52 \ingroup qtquick-particles-
53-
54 This element emits logical particles into the ParticleSystem, with the-
55 given starting attributes.-
56-
57 Note that logical particles are not-
58 automatically rendered, you will need to have one or more-
59 ParticlePainter elements visualizing them.-
60-
61 Note that the given starting attributes can be modified at any point-
62 in the particle's lifetime by any Affector element in the same-
63 ParticleSystem. This includes attributes like lifespan.-
64*/-
65-
66-
67/*!-
68 \qmlproperty ParticleSystem QtQuick.Particles::Emitter::system-
69-
70 This is the Particle system that the Emitter will emit into.-
71 This can be omitted if the Emitter is a direct child of the ParticleSystem-
72*/-
73/*!-
74 \qmlproperty string QtQuick.Particles::Emitter::group-
75-
76 This is the logical particle group which it will emit into.-
77-
78 Default value is "" (empty string).-
79*/-
80/*!-
81 \qmlproperty Shape QtQuick.Particles::Emitter::shape-
82-
83 This shape is applied with the size of the Emitter. Particles will be emitted-
84 randomly from any area covered by the shape.-
85-
86 The default shape is a filled in rectangle, which corresponds to the full bounding-
87 box of the Emitter.-
88*/-
89/*!-
90 \qmlproperty bool QtQuick.Particles::Emitter::enabled-
91-
92 If set to false, the emitter will cease emissions until it is set to true.-
93-
94 Default value is true.-
95*/-
96/*!-
97 \qmlproperty real QtQuick.Particles::Emitter::emitRate-
98-
99 Number of particles emitted per second.-
100-
101 Default value is 10 particles per second.-
102*/-
103/*!-
104 \qmlproperty int QtQuick.Particles::Emitter::lifeSpan-
105-
106 The time in milliseconds each emitted particle should last for.-
107-
108 If you do not want particles to automatically die after a time, for example if-
109 you wish to dispose of them manually, set lifeSpan to Emitter.InfiniteLife.-
110-
111 lifeSpans greater than or equal to 600000 (10 minutes) will be treated as infinite.-
112 Particles with lifeSpans less than or equal to 0 will start out dead.-
113-
114 Default value is 1000 (one second).-
115*/-
116/*!-
117 \qmlproperty int QtQuick.Particles::Emitter::lifeSpanVariation-
118-
119 Particle lifespans will vary by up to this much in either direction.-
120-
121 Default value is 0.-
122*/-
123-
124/*!-
125 \qmlproperty int QtQuick.Particles::Emitter::maximumEmitted-
126-
127 The maximum number of particles at a time that this emitter will have alive.-
128-
129 This can be set as a performance optimization (when using burst and pulse) or-
130 to stagger emissions.-
131-
132 If this is set to a number below zero, then there is no maximum limit on the number-
133 of particles this emitter can have alive.-
134-
135 The default value is -1.-
136*/-
137/*!-
138 \qmlproperty int QtQuick.Particles::Emitter::startTime-
139-
140 If this value is set when the emitter is loaded, then it will emit particles from the-
141 past, up to startTime milliseconds ago. These will simulate as if they were emitted then,-
142 but will not have any affectors applied to them. Affectors will take effect from the present time.-
143*/-
144/*!-
145 \qmlproperty real QtQuick.Particles::Emitter::size-
146-
147 The size in pixels of the particles at the start of their life.-
148-
149 Default value is 16.-
150*/-
151/*!-
152 \qmlproperty real QtQuick.Particles::Emitter::endSize-
153-
154 The size in pixels of the particles at the end of their life. Size will-
155 be linearly interpolated during the life of the particle from this value and-
156 size. If endSize is -1, then the size of the particle will remain constant at-
157 the starting size.-
158-
159 Default value is -1.-
160*/-
161/*!-
162 \qmlproperty real QtQuick.Particles::Emitter::sizeVariation-
163-
164 The size of a particle can vary by this much up or down from size/endSize. The same-
165 random addition is made to both size and endSize for a single particle.-
166-
167 Default value is 0.-
168*/-
169/*!-
170 \qmlproperty StochasticDirection QtQuick.Particles::Emitter::velocity-
171-
172 The starting velocity of the particles emitted.-
173*/-
174/*!-
175 \qmlproperty StochasticDirection QtQuick.Particles::Emitter::acceleration-
176-
177 The starting acceleraton of the particles emitted.-
178*/-
179/*!-
180 \qmlproperty qreal QtQuick.Particles::Emitter::velocityFromMovement-
181-
182 If this value is non-zero, then any movement of the emitter will provide additional-
183 starting velocity to the particles based on the movement. The additional vector will be the-
184 same angle as the emitter's movement, with a magnitude that is the magnitude of the emitters-
185 movement multiplied by velocityFromMovement.-
186-
187 Default value is 0.-

191 \qmlsignal QtQuick.Particles::Emitter::emitParticles(Array particles)-
192-
193 This signal is emitted when particles are emitted. particles is a JavaScript-
194 array of Particle objects. You can modify particle attributes directly within the handler.-
195-
196 Note that JavaScript is slower to execute, so it is not recommended to use this in-
197 high-volume particle systems.-
198-
199 The corresponding handler is \c onEmitParticles.-
