Struct zng_app :: update :: EventUpdate Copy item path

impl EventUpdate

pub fn event(&self) -> AnyEvent

The event.

pub fn delivery_list(&self) -> &UpdateDeliveryList

The update delivery list.

pub fn delivery_list_mut(&mut self) -> &mut UpdateDeliveryList

Mutable reference to the update delivery list.

Note that this is only available app-extensions, nodes don’t get mutable access to the event update.

pub fn args(&self) -> &dyn AnyEventArgs

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.
