Trait guion::handler::Handler[−][src]

pub trait Handler<E>: Sized + 'static where
    E: Env, {
    fn _render(l: Link<'_, E>, r: &mut RenderLink<'_, E>);

    fn _event_direct(l: Link<'_, E>, e: &EventCompound<E>) -> EventResp;

    fn _event_root(l: Link<'_, E>, e: &EventCompound<E>) -> EventResp;

    fn _size(l: Link<'_, E>, e: &EStyle<E>) -> ESize<E>;

    fn _send_event(
        l: Link<'_, E>, 
        e: &EventCompound<E>, 
        child: E::WidgetPath
    ) -> Result<EventResp, GuionError<E>>;
}

Handlers are stacked inside a Context and any render/event/size action goes through the handler stack
