Ah, that explains it. Thanks, Yair. Perhaps other LNFs (weblaf, PgsLookAndFeel, etc.) are the same way as well.

@HAC – JTattoo LNFs cannot be used like simple LNFs. Take a look at the source code of the utility to see how they can be used.

 
hFig = figure;
hc = uiflowcontainer('v0', 'Units', 'norm', 'Position', [0.1 0.1 0.8 0.8]);
h1 = uicontrol('String', 'One', 'Parent', hc);
javaaddpath ./JTattoo-1.6.10.jar;
m = javax.swing.UIManager();
oldLF = m.getLookAndFeel;
newLFName1 = 'com.jtattoo.plaf.aero.AeroLookAndFeel'; % This one fails!
newLFName2 = 'com.jgoodies.looks.plastic.Plastic3DLookAndFeel'; % This one works!
m.setLookAndFeel(newLFName1);
[j2, h2] = javacomponent(javax.swing.JButton('Two')); 
set(h2, 'Parent', hc);
m.setLookAndFeel(oldLF);

I expect to see two buttons, each with a different look and feel. However, I’ve tried every iteration of accessing the jtattoo LaF’s and can’t seem to set them. The .jar shows up when I type ‘javaclasspath’, so I think it should be accessible. This same error occurs regardless of which LaF I try to access from the JTattoo library, as well as any other 3rd-party library. However, if I use ‘newLFName2’ above, things work nicely.

So, I suspect I’m not understanding how to access the 3rd-party classes correctly. Any advice for a beginner?

@Kilojoules – of course you can – read here: http://undocumentedmatlab.com/blog/modifying-matlab-look-and-feel/

Thanks.

@Digna – I normally use ‘/folder/file’ format for compatibility (this works on all platforms), it was simply an oversight in this case… – thanks for pointing it out

javaclasspath( {folder, [folder '\JTattoo.jar']} );

to:

javaclasspath( {folder, [folder filesep 'JTattoo.jar']} );

because in GNU/Linux the file separator is “/” and not “\” 🙂
