です。
前回までのプログラムで定義だけして活用していなかった変数 fileClean をチェックするようにして、アニメデータが変更されているのに新しいファイルを開こうとしたりウインドウを閉じようとすると
のようなダイアログが出て保存を促します。いままではメインのフレーム（アニメのフレームではなくＳｗｉｎｇのJFrame）のデフォルト終了処理に EXIT_ON_CLOSE を指定していましたが、今回からは DO_NOTHING_ON_CLOSE にしてウインドウリスナの windowClosing メソッドで終了処理をします。
また、ＭＳＸ版と同様に一番最後のフレームで「＞」ボタンを押すと
のようなダイアログが出て新規フレームを作成できるようにしました。
以下、プログラムソースです。
