java - 物质外观的问题

Question

我已经按内容下载了最新的库，我还下载了用于支持 SwingX 组件的插件。当我运行我的应用程序时，我仍然收到以下错误

第一个问题是你在 EDT 上正确添加了 Substance L&F

现在

SwingUtilities.invokeLater(new Runnable() {

        @Override
        public void run() {
            try {
                UIManager.setLookAndFeel(new SubstanceOfficeSilver2007LookAndFeel());
                SwingUtilities.updateComponentTreeUI(frame);
            } catch (UnsupportedLookAndFeelException e) {
                throw new RuntimeException(e);
            }
        }
    });
