问题


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:

I do not understand what is happening.

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.
