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.

Seesaw: Clojure + UI

"killing CamelCase, proxy and reify, one class at a time"

Seesaw's experimental and subject to radical change

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-dae and trustworthy.

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.

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 "1.2.0"]
                [org.clojure/clojure-contrib "1.2.0"]
                [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: As mentioned above, Seesaw is experimental and changing daily. Thus, there's a good chance that what's on clojars and what's written here are out of sync. 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
