What is the best way to do GUIs in Clojure?

Question

What is the best way to do GUIs in Clojure?

Is there an example of some functional Swing or SWT wrapper? Or some integration with JavaFX declarative GUI description

Answer 1

I will humbly suggest Seesaw.

Here's a REPL-based tutorial that assumes no Java or Swing knowledge.

Seesaw's a lot like what @tomjen suggests. Here's "Hello, World":

(use 'seesaw.core)

(-> (frame :title "Hello"
       :content "Hello, Seesaw"
       :on-close :exit)
  pack!
  show!)

and here's @Abhijith and @dsm's example, translated pretty literally:

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

(defn handler
  [event]
  (alert event
    (str "Hello from Clojure. Button "
      (.getActionCommand event) " clicked.")))

(-> (frame :title "Hello Swing" :on-close :exit
           :content (button :text "Click Me" :listen [:action handler]))
  pack!
  show!)
