Ok! this sounds very promising this should decouple the rendering thread and the input handling thread. so i can set to the wl_seat client object a new queue and then pass this queue to wl_display_dispatch_queue call in the input thread.
but one question to this: the documentation of wl_display_dispatch_queue says: "For other threads this will block until the main thread queues events on the queue passed as argument." So will pass the events in the queue or how to achieve this it the second thread( rendering thread is sleeping)?? In my use case the input thread should wake up when input event arrives from the compositor also when all other thread of the client are idle. 2013/10/19 Giulio Camuffo <giuliocamu...@gmail.com> > You can move a client-side wayland object to a queue using the function > void wl_proxy_set_queue(struct wl_proxy *proxy, struct wl_event_queue > *queue). > All the client-side objects are really wl_proxy, so you can safely cast > them. > If you move to a queue an object which creates new objects and > dispatches them through > an event those objects will be in the same queue too. > > > 2013/10/18 Eugen Friedrich <fried...@gmail.com>: > > Hallo Giulio, > > thanks a lot for the fast replay. > > > > if my understanding is correct the frame callbacks and the input handling > > events are coming from the compositor to the main wayland display queue > on > > the client side. > > So how i can get the different queues on the client site or is there a > > possibility to get a separate queue for input events? > > > > > > 2013/10/18 Giulio Camuffo <giuliocamu...@gmail.com> > >> > >> Oh, I sent my mail before the second one arrived. > >> > >> Yeah, you need to use different wl_event_queues, and the relative > >> functions like > >> wl_display_dispatch_queue. > >> > >> 2013/10/18 Giulio Camuffo <giuliocamu...@gmail.com>: > >> > And what is it that doesn't work?
