 ### 発生している問題
-パネルに後からパネルを貼り付けて拡張するようなイメージで記述したのですが，上手くいきませんでした.
+現段階では送信ボタンを押すと，メッセージを出すようにしているのですが，その描画が反映されない状況です。
-そもそも作り方として合っているのか分からないため，なかなかほしい情報がヒットしなく手が止まっちゃっています.
+また，送信ボタン周りの操作クラスが再描画によってつぶれてしまい，適切な領域が割り当てられていなく，スクロールもない状態になってしまっています．
+ChatBounddaryの継承をJPanelに変更したことで，add(scrollPane, BorderLayout.CENTER);を書く適切な位置がわからなくなってしまいました．

-### 試したこと
-panel以外でチャットの枠を構成できないか調べ,JListを使って出来るのかと今ネットを探っている段階です.

完成したイメージの図を新たに付け加えた。
