ページの作成:「==Jython JTextComponent 1== [JTextComponent 1][Jython Swing][Swing][Jython][Python] ===方針=== *半ば強引に、[JTextComponent 1] [Swingで作成したサンプ…」

新規ページ

==Jython JTextComponent 1==
[JTextComponent 1][Jython Swing][Swing][Jython][Python]

===方針===
*半ば強引に、[JTextComponent 1] [Swingで作成したサンプル]を Jythonに書き換えてみる。

===内容===
*メニューとアクションの割付
*キーボード押下との割付
*Undo、Redoの実装
*Documentの利用
*Documentのイベント感知
