Handle to an event queue

This handle gives you access to methods on an event queue that are safe to do from within a callback.

They are also available on an EventQueue object via Deref.

Methods

impl EventQueueHandle

fn register<P: Proxy, H: Handler<P> + Any + 'static>(&mut self, proxy: &P, handler_id: usize)[−]

Register a proxy to a handler of this event queue.

The H type must be provided and match the type of the targetted Handler, or it will panic.

This overwrites any precedently set Handler for this proxy.

fn add_handler<H: Any + 'static>(&mut self, handler: H) -> usize[−]

Insert a new handler to this event queue

Returns the index of this handler in the internal array, which is needed to register proxies to it.
