Module Brr.EvSource

The type for events which can pose as values of type 'a. See the predefined event types.

Event types.

The type for events that do not expose further data.

The type for EventTarget abiding objects.

The type for event initialisation objects.

init is an event initialisation object with given parameters.

The type for Event objects which can pose as events of type 'a.

See t.

create ?init t is an event of type t initialised with init.

as_type e specialises the event to its type.

type' e is the type of e.

target e is the target on which e was originally dispatched.

current_target e is the target currently handling e. See also target.

composed_path e are the targets on which listeners will be invoked.

event_phase e is e's event phase, see here for details. This picture may help.

bubbles e is true whether the event can bubble up through the DOM.

stop_propagation e prevents the propagation of e in the DOM, remaining handlers of e on the current_target are still invoked use stop_immediate_propagation to stop these. The user agent's default action for e still occurs, use prevent_default to prevent that.

stop_immediate_propagation e is like stop_propagation but it also prevents the invocation of other handlers for e that may be listening on the current_target.

cancelable e indicates whether e can be cancelled, that is whether prevent_default will succeed.

prevent_default e prevents the user agent's default action for e to happen. This may have no effect if cancelable is false, see default_prevented.

default_prevented e is true indicates whether a call to prevent_default succeded.

composed e is the composed property of e.

is_trusted e is true if e was dispatched by the user agent and false otherwise.

timestamp_ms e is the time in milleseconds since the POSIX epoch when the event was created.

dispatch e t dispatches event e on target t.

The type for listening options.

listen_opts () are options for listen.

• capture indicates if events are listened before being dispatched to descendents of the target in the DOM tree. Defaults to false.
• once indicates at most a single event will be listened. If true the listener is automatically removed when invoked. Defaults to false.
• passive indicates the listener never calls prevent_default on the event. If it does nothing will happen (except maybe a console warning). Defaults to false.

The type for event listeners. See listen.

listen ~opts type' f t is a listener listening for events of type type' on target t with function f and options opts (see listen_opts for defaults). The listener can be used to unlisten, if you don't need to, you can just `ignore` the result.

unlisten l stops the listening done by l.

next type' t is a future that determines the next event of type type' on target t. For capture see listen_opts.
