私はこのコードで何時間も働いており、ついに完成まで近づいてきました。右クリックで鉱山にフラグを立てる機能を追加する方法を見つけたら、私は鉱山カウンターとタイマーを追加します。 JButtonは右クリックを認識しないので、MouseEventを使用する必要があります。そこから、私は失われています。誰かが私に正しい方向に微笑んでくれますか？Minesweeper GUIゲームのためのフラッグボタン
これは私が現在持っているものです。

私はあなたの質問を理解していません。 'e.getButton（）== MouseEvent.BUTTON3' – Jhonny007
@ Jhonny007' MouseEvent.BUTTON3'はあいまいです。 Button3は、マウス/ OSなどによって異なるかもしれません...また、彼は右クリックの検出が、それがホバリングしているボタンにどのように結びついているのかを尋ねています。彼が言うように、ボタンは右クリックを直接検出することはできません。 – Cutter
