Struct EventDelegate

pub struct EventDelegate { /* private fields */ }

Event delegate manages capturing, targeting, and bubbling of events

Implementations

impl EventDelegate

pub fn new(component_id: Option<usize>) -> Self

Create a new event delegate

pub fn set_parent(&mut self, parent: Arc<Mutex<EventDelegate>>)

Set the parent delegate for bubbling events

pub fn add_child(&mut self, child: Arc<Mutex<EventDelegate>>)

Add a child delegate for capturing events

pub fn capture<E: Event + 'static>( &self, handler: impl Fn(&E, &EventPropagation) + Send + Sync + 'static, )

Register a handler for an event type in the capturing phase

pub fn bubble<E: Event + 'static>( &self, handler: impl Fn(&E, &EventPropagation) + Send + Sync + 'static, )

Register a handler for an event type in the bubbling phase

pub fn on<E: Event + 'static>( &self, handler: impl Fn(&E, &EventPropagation) + Send + Sync + 'static, )

Register a handler for an event type for this target only

pub fn dispatch<E: Event + 'static>(&self, event: &E, target_id: Option<usize>)

Dispatch an event starting from this delegate
