この質問、Java Swing：固定幅と可変高さの垂直レイアウトは、ApachePivotを試す機会を与えてくれました。私はPivotでちょうど1日の経験があります。
これが私が作成できたGUIです。
私の質問は次のとおりです。
、、、がウィンドウの幅を埋め、任意の量のテキストを保持するのに十分な高さになるように、の
TextArea一部のサイズを設定するにはどうすればよいですか？ExpanderExpanderScrollPaneTextAreaTextAreaすべてのテキスト領域が展開されたときに3がウィンドウの高さに合うように、の高
ScrollPaneさのサイズを設定するにはどうすればよいですか？ExpanderExpander
GUIを作成したソースコードは次のとおりです。ApachePivotのバージョン2.0.2を使用しています。
