<h2 id="details">Detailed Description</h2>
<p>This element allows you to set timed transitions on particle groups.</p>
<p>You can also use this element to group particle system elements related to the logical particle group. Emitters, Affectors and Painters set as direct children of a <a href="qml-qtquick-particles-particlegroup.html">ParticleGroup</a> will automatically apply to that logical particle group. TrailEmitters will automatically follow the group.</p>
<p>If a <a href="qml-qtquick-particles-particlegroup.html">ParticleGroup</a> element is not defined for a group, the group will function normally as if none of the transition properties were set.</p>
