Java 操作系统外观错误？

我试图在我的应用程序中使用操作系统的外观，但我在按钮的显示上遇到了问题

基本上，我把代码放在我的JFrame中，从JFrame中我可以访问我有问题的GamePanel

下面是GamePanel的外观：

这些不是windows按钮

JFrame代码：

public class Fenetre extends JFrame {

        private JMenuBar menu = new JMenuBar();
        private JMenu file = new JMenu("Fichier");
        private JMenuItem neew = new JMenuItem("Nouveau");
        private JMenuItem score = new JMenuItem("Score");
        private JMenuItem quit = new JMenuItem("Quitter");
        private JMenu about = new JMenu("About");
        private JMenuItem how = new JMenuItem("Règles");
        private JMenuItem who = new JMenuItem("Credit");
        private int i=1;
        private ScorePanel scorepan = new ScorePanel(900,650);
        private ReglesJeuPanel rgpan = new ReglesJeuPanel(900,650);
        private GamePanel gamepan = new GamePanel();
        private JPanel pan = new JPanel();

        private JLabel label = new JLabel("------------------------SAMAIKOM------------------------");
        private JTextArea texte = new JTextArea(    "Vous avez sept coups pour trouver le mot caché. Si vous réussissez, on recommence !\n" +
                "Plus vous trouvez de mots, plus votre score augmente. Alors, à vous de jouer !\n" +
                "Proverbe :\t« Pas vu, pas pris !\n" +

在添加按钮之前，需要先放置uimanager.setLookAndFeel。我会把它放在main方法以及按钮和setVisible中。我通常不会制定设置LaF的方法。

您是否按照文档中的说明进行了尝试。请显示你的代码。我编辑了我的帖子，添加了JFrame和GamePanel代码，在你的主要方法中设置了外观。你的主要方法在哪里？FrankelStein，用这个代码。但只有在加载swing组件后动态更改外观时才需要它，否则，在主方法中创建任何swing组件之前，只需设置OS外观，并跳过对updateComponenetTreeUI的调用；setLookAndFeel很好，是的，Anthony是对的。在初始化应用程序之前设置L&F时，不需要设置updateComponentTreeUI：
