我已经按实质内容下载了最近的库,并且我已经下载了插件以支持SwingX组件。运行我的应用程序时,我仍然收到以下错误

1.问题是您在EDT上正确添加了物质L&amp; F
f.e。
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(new SubstanceOfficeSilver2007LookAndFeel());
SwingUtilities.updateComponentTreeUI(frame);
} catch (UnsupportedLookAndFeelException e) {
throw new RuntimeException(e);
}
}
});
