+    \qmlsignal QtQuick.Particles2::Affector::affectParticle(particle, dt)
+
+    This handler is called when particles are selected to be affected.
+
+    dt is the time since the last time it was affected. Use dt to normalize
+    trajectory manipulations to real time.
+
+    Note that JS is slower to execute, so it is not recommended to use this in
+    high-volume particle systems.
