Implementations

impl EventTarget

fn __assert_parent_type(&self)

impl EventTarget

pub(crate) fn type_id(&self) -> &'static EventTargetTypeId

impl EventTarget

pub(crate) fn new_inherited() -> EventTarget

fn new( global: &GlobalScope, proto: Option<HandleObject<'_>>, can_gc: CanGc, ) -> DomRoot<EventTarget>

fn notify_listener_added(&self, ty: &Atom)

Notify the global about a listener being added for a given event type.

fn notify_listener_removed(&self, ty: &Atom)

Notify the global about a listener being removed for a given event type.
