Macのアプリケーション名メニューのaboutメッセージを作成するにはどうすればよいですか？

Question

Macの[アプリケーション名]メニューの[バージョン情報]オプションをどのように作成できますか？私はアプリケーションのバージョン名を表示するメッセージを持っていると思います。

は、このリンクを試してみて下さいとのJMenuBarとのJMenuItemについて読ん

を慎重にあなたの質問を読んだ後、今、私はあなたが望むものを理解試してみてください

System.setProperty("apple.laf.useScreenMenuBar", "true"); 

をメインの方法で使用し、動作するかどうかを確認してください。

例 - コードは、例示の目的のために編集されて

私は（ここでは、挿入アプリケーション名）遍在オプションで、画面の最上部にあるメニューバーにそれを置くことを意味
