[Caml-list] [ANN]Amthing - a multi-threaded GUI library

[Satoshi Ogasawara]

Hello list,

I'm please to announce the first public release of Amthing, a multi-threaded
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 ()

you can clone the repository from OCamlForge subversion :

svn checkout svn://svn.forge.ocamlcore.org/svnroot/amthing

or view souce code on the web.

1. Are there any screenshots?

2. Is there a widget system like in GTK/Qt?

3. What is the domain space covered by this library? Was it made for
a specific purpose? IT Planning, Inc. is apparently a Japanese company
using OCaml but the main software is using Java Swing GUI.

Sincerely yours,
david

Widgets are under developing. We will support button, label, textbox,
checkbox, radio button, tab, listbox, tree, grid,..etc. We already supports
Pango and XIM for textbox.

The main purpose is to develop an ordinary desktop application covered
by GTK/Qt. In addition, Amthing is applicable to rich client which access
to internet services. Animation makes application rich. Concurrent environment
helps us to write asynchronous communications.

Have you planned to write a little introductory tutorial so that we could do
some tests and give feedback about Amthing ?

Thanks.

Great. Keep us updated :-)
