Nimbus 的 Matlab 外观和感觉

发布于 2025-01-04 14:51:54 字数 8739 浏览 1 评论 0原文

我正在尝试使用 Java 更改 Matlab GUI 的外观。按照此处找到的帖子的说明，我尝试了这段代码：

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

但是，结果未正确显示，并且我收到以下错误消息：

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');

However, the results are not shown correctly and I am getting the following error messages:

阅读您提供的链接的评论部分。引用:

更改 L&F 确实会导致 Java 异常出现问题
抛出。要更改整个桌面，请设置 L&F 然后调用：

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

我尝试过，但只是更改了某些部分，并且 GUI 变得相当无法使用。我在 Linux 上运行 Matlab 2010。

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

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);

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