问题描述

我正在尝试使用Java更改Matlab GUI的外观.按照在此找到的帖子的说明，我已经尝试过此代码:

I am trying to change the appearance of my Matlab GUI using Java. Following the instructions of the post found here, I have tried this code:

javax.swing.UIManager.setLookAndFeel('com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel');

但是，结果无法正确显示，并且出现以下错误消息:

我不知道发生了什么.

推荐答案

阅读您提供的链接的注释部分.报价:

Reading the comment section of the link you provided. Quoting:

更改L& F确实会导致与Java异常有关的问题 抛出.要更改整个桌面，请设置L& F，然后调用:

Changing the L&F does cause problems with Java exceptions being thrown. To change the entire desktop, set the L&F then invoke:

f=com.mathworks.mde.desk.MLDesktop.getInstance.getMainFrame();
javax.swing.SwingUtilities.updateComponentTreeUI(f); 

我尝试过，但是只有一部分被更改，并且GUI变得相当不可用.我在Linux上运行Matlab 2010.

I tried it, but just some part are changed, and the GUI becomes fairly unusable. I was running Matlab 2010 on Linux.

这篇关于Matlab的Nimbus外观的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
