The update args.

pub fn with_window<H, R>(&self, handle: H) -> Option<R>

where H: FnOnce() -> R,

Calls handle if the event targets the WINDOW.

pub fn with_widget<H, R>(&self, handle: H) -> Option<R>

where H: FnOnce() -> R,

Calls handle if the event targets the WIDGET and propagation is not stopped.

pub fn custom(&self, delivery_list: UpdateDeliveryList) -> EventUpdate

Create an event update for the same event and args, but with a custom delivery_list.

Note that the returned instance can only be used to notify app extensions or nodes that the caller can reference.
