飛行機をボード全体に移動したいです。私は「私は（真）setFocusableまし 前にそれをやったので、 これは非常に単純である必要があり、私はのKeyListenerを追加しました、と私は私が何か分からないKeyListenerが応答しません
）（requestFocusInWindowもしまし間違っ
キーが押され、それも私が「こんにちは」プリントアウトしようとすることでテスト
KeyPressed方法を入力しないであろう。

を私はちょうど方法を入力したい、私は後で移動の事を変更します
助けてください！これは私の合計です –
いいえ[mcve]、なぜですか？コードを実行してテストするにはどうすればよいですか？ Key Bindingsの使用を推奨する類似の質問とはどのように違いますか？ –
