Struct wayland_client::EventQueueHandle

pub struct EventQueueHandle { /* fields omitted */ }

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 + Send + '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 + Send + '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.

fn add_handler_with_init<H: Init + Any + Send + 'static>(&mut self,
                                                         handler: H)
                                                         -> usize

Insert a new handler with init

Allows you to insert handlers that require some interaction with the event loop in their initialization, like registering some objects to it.

The handler must implement the Init trait, and its init method will be called after its insertion.
