外观在Swing中不会更新JTabbedPane

我已经在Java Swing中创建了一个应用程序。我提供了从菜单中更改应用程序的外观和风格的选项，但是在JTabbedPane中添加了新选项卡之后，它没有得到新的外观和感觉。外观在Swing中不会更新JTabbedPane

我已经使用这个代码：

Window windows[] = Frame.getWindows(); 
for(Window window : windows) { 
    SwingUtilities.updateComponentTreeUI(window); 
}

你能告诉我们一些更多的代码，也许是添加你的Jtabbedpane的代码？ – Kostronor 2012-08-14 06:05:56

您是否设定了新的外观？听起来很明显，但有时显而易见的东西会丢失：D'UIManager.setLookAndFeel（lnfName）;' – zip 2012-08-14 06:07:19

凭借@安德鲁example和这个老thing，它似乎为我工作。
