1) Amthing - a multi-threaded GUI library

Here is the latest Caml Weekly News, for the week of April 07 to 14, 2009. Archive: <http://groups.google.com/group/fa.caml/browse_thread/thread/af09a302fa8ab70e# >

------------------------------------------------------------------------
** Ogasawara Satoshi announced:


GUI library for OCaml.

Features are:

- Multi-threaded design using Concurrent ML style message passing.
- Time-line animation and functional reactive sprite system.
- X11 Binding.
- 2D vector rendering by cairo.

Here's a "Hello world" example of Amthing.

 open Ccell
 open Event
 open Amthing.Util.Persavatives

 module W = Amthing.Core.Window ( Amthing.XWindow )
 module K = Amthing.KeyCode
 module E = Amthing.WinEvent
 module S = Amthing.Sprite
 module C = Amthing.Component
 let wh = W.make  (Amthing.XWindow.default_parameter ())
 let tc = lazy (W.make_text_context wh)

 let _ =
   W.resize wh {| x = 0; y = 0; w = 200; h = 200 |};
   let hello =
     new S.label !$tc "hello world!"
       +> S.set (`X 55.)
       +> S.set (`Y 90.)
       +> S.set (`Color Amthing.Color.blue)
       +> C.make
   in
   W.add_visible wh hello;
   W.set_title wh "amthing hello world!";
   W.show wh;
   let main_loop () =
     match select [ Bcast.receive (W.event wh) ] with
       `KEY_PRESS input when E.key_code input = Some K._q ->
              W.close wh;
              exit 0
     | #E.t -> ()
   in
   forever main_loop ()

Here is a quick trick to help you read this CWN if you are viewing it using (alan.schm...@polytechnique.org) and I'll mail it to you, or go take a look at The hacker: someone who figured things out and made something cool happen.
