Struct intuitive::event::handler::Handler

pub struct Handler<T> { /* private fields */ }

A generic handler for mouse and keyboard events.

Implementations

impl<T: 'static + Copy> Handler<T>

pub fn handle(&self, event: T)

Call the handler on the event.

pub fn handle_or<F, R>(&self, event: T, alternative_handler: F)where F: FnOnce(T) -> R,

Call the handler on the event, defaulting to the alternative_handler.

pub fn then<F>(&self, next_handler: F) -> Selfwhere F: Fn(T) -> Propagate + 'static + Send + Sync,

Create a new handler that propagates to next_handler.

Propagation only occurs if this handler returns Propagate::Next.
