プログラミング上の問題操作リスナー-FillRect

Java GUI形式のゲームマスタを再作成しようとしています。私の問題は、ActionListenerが私のNewPanelクラスにアクセスすることができないことに由来します。どんな助けも素晴らしく、本当にこれに執着しています。プログラミング上の問題操作リスナー-FillRect

ボタンに応じて色を変更するボックスがあります。私はあなたがここからそれを取りたいと思っていませんが、これは良いスタートになるはずです。

したがって、すべてのJPanelsをnewPanelクラスに置き換える必要がありますか？ – Matt

この宿題はありますか？ – eabraham

これは宿題ではありませんが、私は別のフォーラムからそのアイデアを得ました。私はguiに新しいと試して楽しいプロジェクトのように聞こえました – Matt
