手动设置 Swing JInternalFrame lnf

UIManager.put("InternalFrame.activeTitleBackground", new ColorUIResource(new Color(207,255,247)));
UIManager.put("InternalFrame.inactiveTitleBackground", new ColorUIResource(new Color(207,255,247)));
JDesktopPane baTabbedPane = new JDesktopPane();
JInternalFrame iframe = new JInternalFrame("Cheapest To Deliver",true,true,true,true);
iframe.setSize(400,150);
baTabbedPane.add(iframe);

为什么我的内部框架的标题背景在启动时没有设置？

我尝试在整体 JFrame init 上设置它，但没有什么区别（相比之下，我可以更改其他 JFrame ui 组件的外观和感觉，例如 MenuItem.background 在这个位置，所以我认为这可能是因为 JInternalFrame 不是顶级组件，即选项卡式窗格下的组件，也许它需要在其他点进行更改，但是在哪里？）

关于为 JInternalFrame 调用 UIManager.put() 的正确位置有什么提示吗？

原文

UIManager.put("InternalFrame.activeTitleBackground", new ColorUIResource(new Color(207,255,247)));
UIManager.put("InternalFrame.inactiveTitleBackground", new ColorUIResource(new Color(207,255,247)));
JDesktopPane baTabbedPane = new JDesktopPane();
JInternalFrame iframe = new JInternalFrame("Cheapest To Deliver",true,true,true,true);
iframe.setSize(400,150);
baTabbedPane.add(iframe);

why is my Internal Frame's title background not set on startup?

I've tried setting it on the overall JFrame init but made no difference (By contrast I could change other JFrame ui component look n feel such as MenuItem.background in this location so I thought it might have been because the JInternalFrame was not a top-level component i.e. under a tabbed pane, that maybe it needed changing at some other point, but where?)

Any tips on the correct place to call UIManager.put() for JInternalFrame?

最终得到它 - 在 JInternalFrame 创建之后对 put() 的调用工作正常，但我在将组件添加到容器之前确实做到了。然后我仍然需要设置它的用户界面：

JInternalFrame iframe = new JInternalFrame("blah",true,true,true,true);
UIManager.put("InternalFrame.activeTitleBackground", new ColorUIResource(new Color(248,250,175)));
UIManager.put("InternalFrame.inactiveTitleBackground", new ColorUIResource(new Color(248,250,175)));
javax.swing.plaf.basic.BasicInternalFrameUI ui = 
    new javax.swing.plaf.basic.BasicInternalFrameUI(iframe); 
iframe.setUI(ui);

got it eventually - the call to put() works fine after JInternalFrame creation but I did make it before I added the component to a container. I then still had to set it's UI:

JInternalFrame iframe = new JInternalFrame("blah",true,true,true,true);
UIManager.put("InternalFrame.activeTitleBackground", new ColorUIResource(new Color(248,250,175)));
UIManager.put("InternalFrame.inactiveTitleBackground", new ColorUIResource(new Color(248,250,175)));
javax.swing.plaf.basic.BasicInternalFrameUI ui = 
    new javax.swing.plaf.basic.BasicInternalFrameUI(iframe); 
iframe.setUI(ui);
