gtk:event-controller-propagation-phase (object)

object -- a gtk:event-controller object
phase -- a gtk:propagation-phase value

The accessor for the propagation-phase slot gets or sets the propagation phase at which controller handles events. If phase is :none, no automatic event handling will be performed, but other additional gesture maintenance will. In that phase, the events can be managed by calling the gtk:event-controller-handle-event function.
