Note that current development is on the develop branch, not master

There's now a [Google Group] (https://groups.google.com/group/seesaw-clj) for discussion and questions.

[Here's a brief tutorial] (https://gist.github.com/1441520) that covers some Seesaw basics. It assumes no knowledge of Swing or Java.

Seesaw: Clojure + UI

See [the Seesaw Wiki] (https://github.com/daveray/seesaw/wiki) and [the Seesaw API Docs] (http://daveray.github.com/seesaw/) for more detailed docs. Note that the docs in the code (use the doc function!) are always the most up-to-date and trustworthy. t Seesaw is a library/DSL for constructing user interfaces in Clojure. It happens to be built on Swing, but please don't hold that against it. It's an experiment to see what I can do to make user interface development funner in Clojure. It's kinda inspired by Shoes, Stuart Sierra's Swing posts, etc. clojure.contrib.swing-utils is useful, but minimal and still means a lot of "Java-in-Clojure" coding.

Features

Seesaw is compatible with both Clojure 1.2 and 1.3.

• Construct widgets with simple functions, e.g. (listbox :model (range 100))
• Support for all of Swing's built-in widgets as well as SwingX.
• Support for all of Swing's layout managers as well as MigLayout, and JGoodies Forms
• Convenient shortcuts for most properties. For example, :background :blue or :background "#00f", or :size [640 :by 480].
• CSS-style selectors with same syntax as Enlive.
• Unified, extensible event API
• Unified, extensible selection API
• Widget binding, i.e. map changes from one widget into one or more others in a more functional style. Also integrates with Clojure's reference types.
• Graphics
• i18n
• An extensive test suite

There are numerous Seesaw examples in test/seesaw/test/examples.

TL;DR

Here's how you use Seesaw with [Leiningen] (https://github.com/technomancy/leiningen)

Install lein as described and then:

$ lein new hello-seesaw
$ cd hello-seesaw

Add Seesaw to project.clj

(defproject hello-seesaw "1.0.0-SNAPSHOT"
  :description "FIXME: write"
  :dependencies [[org.clojure/clojure "1.3.0"]
                [seesaw "x.y.z"]])

Replace the Seesaw version with whatever the latest version tag is. See below!

Now edit the generated src/hello_seesaw/core.clj file:

(ns hello-seesaw.core
  (:use seesaw.core))

(defn -main [& args]
  (invoke-later 
    (-> (frame :title "Hello", 
           :content "Hello, Seesaw",
           :on-close :exit)
     pack!
     show!)))

Now run it:

$ lein run -m hello-seesaw.core

NOTE: Here's how you can run against the bleeding edge of Seesaw:

• Clone Seesaw from github. Fork if you like. Switch to the "develop" branch.
• In your Seesaw checkout, run lein install to build it
• In your project's project.clj file, change the Seesaw version to X.Y.Z-SNAPSHOT to match whatever's in Seesaw's project.clj.
• Run lein deps
• Move along
