私は、JGoodies を使用して JTable 行をテーブルの下のテキスト フィールドにバインドする Java EE プロジェクトで顧客のために働いています。これは正常に機能しますが、1 つのダイアログにフィルタリング チェック ボックスがあります。すべてのチェック ボックス (3 つ) をクリックすると、すべての項目が表示されます。チェックされていない場合、テーブルは空のままです。一部の行をフィルターで除外することは可能ですが、テーブル モデルを使用する JGoodies はこのフィルター処理を認識していません。フィルタリングされたテーブルの最初の行をクリックすると、フィルタリングされていないテーブルの最初の行の要素が下のテキスト フィールドに表示されます。この問題を回避する方法はありますか?
私の意見では、問題は JGoodies の問題ではなく、フィルタリングされたテーブルのテーブル モデルを使用してテキスト フィールドを JGoodies にバインドすることです。
テキスト フィールドを Bindings.bind メソッドでバインドできなかった例を添付しましたが、問題が示されています。私は自分の目的のために、インターネット上で見つけたいくつかのコードを採用しました。
テーブルは、コンボ ボックスの内容に従ってフィルター処理されます。GENERAL タイプの食事が選択されている場合、下のテキスト フィールドのバインドは問題ありません。ただし、コンボ ボックスでテーブル コンテンツの一部を選択した場合でも、下のテキスト フィールドは (フィルター処理されていない) テーブル モデルから情報を取得します。ここで、適切な方法でこれを行う方法についての情報が必要です。
事前に助けてくれてありがとう！
