Required Methods
sourcefn propagation_phase(&self) -> PropagationPhase
fn propagation_phase(&self) -> PropagationPhase
sourcefn handle_event(&self, event: &Event) -> bool
fn handle_event(&self, event: &Event) -> bool
sourcefn reset(&self)
fn reset(&self)
Resets the self
to a clean state. Every interaction
the controller did through signal::EventController::handle-event
will be dropped at this point.
sourcefn set_propagation_phase(&self, phase: PropagationPhase)
fn set_propagation_phase(&self, phase: PropagationPhase)
Sets the propagation phase at which a controller handles events.
If phase
is PropagationPhase::None
, no automatic event handling will be
performed, but other additional gesture maintenance will. In that phase,
the events can be managed by calling handle_event()
.
phase
a propagation phase
