JythonからJavaFX 2を利用する
Windows XP環境で
JavaはJDK 1.7.0_10の場合
Javaはすでに使える状態を想定しています１ Jythonインストール
このサイト（http://www.jython.org/downloads.html）よりDownload Jython 2.7a2をゲット２ インストール手順はこちらInstallation（http://wiki.python.org/jython/InstallationInstructions）
java -jar jython_installer-2.7a2.jar
特に難しいところはないです
D:\jython2.7a2へインストールしたとする
３ ユーザー環境設定（jfxrt.jarのクラスパス設定、jythonのホームとパス設定）
jfxrt.jarのクラスパス設定はコマンドプロンプトから実行するため必須
SET JAVAFX_HOME=D:\Program Files\Java\jdk1.7.0_10
SET CLASSPATH=%JAVAFX_HOME%\jre\lib\jfxrt.jar;%CLASSPATH%
SET PATH=D:\jython2.7a2\bin;%PATH%
SET JYTHON_HOME=D:\jython2.7a2
定番のHello Worldで動作確認
CX's Hello, World!
http://cx20.main.jp/blog/hello/2012/11/28/hello-javafx-jython-world/
jython Hello.py
Mac OS X 10.7.5の環境でなら
１ Jythonインストール
このサイト（http://www.jython.org/downloads.html）よりDownload Jython 2.7a2をゲット２ インストール手順はこちらInstallation（http://wiki.python.org/jython/InstallationInstructions）
java -jar jython_installer-2.7a2.jar
特に難しいところはないです
ホームディレクトリへjython2.7a2がインストールされます
３ .cshrcファイルへ設定
a. まだjfxrt.jarのクラスパス設定をしていない場合はターミナルでJavaFX 2を使えるようにするためjfxrt.jarをクラスパス設定
jfxrt.jarのクラスパス設定はターミナルから実行するため必須setenv CLASSPATH ${CLASSPATH}:/Library/Java/JavaVirtualMachines/jdk1.7.0_10.jdk/Contents/Home/jre/lib/jfxrt.jar
JavaFXホーム設定
setenv JAVAFX_HOME /Library/Java/JavaVirtualMachines/jdk1.7.0_10.jdk/Contents/Home
b. Jythonホームとパス設定
setenv JYTHON_HOME /Users/hshino/jython2.7a2
setenv PATH ${PATH}:/Users/hshino/jython2.7a2/bin
４ 定番のHello Worldで動作確認
CX's Hello, World!（http://cx20.main.jp/blog/hello/2012/11/28/hello-javafx-jython-world/）

５ 既存のJavaFX 2 FXMLアプリをJythonから起動するなら
同じフィルダ内でfxmlファイル名がAnalogClock.fxml、メインクラス（メインスクリプト）をAnalogClock.pyとすると
AnalogClock.py
#!/usr/bin/env jython import sys from javafx.application import Application from javafx.fxml import FXMLLoader from javafx.scene import Scene class AnalogClock(Application): def start(self, stage): root = FXMLLoader.load(self.getClass().getResource('/AnalogClock.fxml')) scene = Scene(root) stage.setScene(scene) stage.show() if __name__ == '__main__': Application.launch(AnalogClock().class, sys.argv[1:])
