手动设置Swing JInternalFrame lnf [英] setting Swing JInternalFrame lnf manually

问题描述

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);

为什么在启动时未设置内部框架的标题背景?

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

我尝试将其设置在整个JFrame init上，但没有区别(通过对比，我可以在此位置更改其他JFrame ui组件的外观，例如MenuItem.background，所以我认为可能是因为JInternalFrame并不是顶级组件，即在选项卡式窗格下，所以可能需要在其他位置进行更改，但是在哪里?)

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?)

在正确的地方打电话给JInternalFrame的任何提示吗?

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

推荐答案

最终得到了它-在JInternalFrame创建之后，对put()的调用工作正常，但是在将组件添加到容器中之前我做到了.然后，我仍然必须设置它的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);
