Nice article with useful information. But i have problem. I try overline text, but it doesnt work.

htmlStr = ['Matlab'];
jEditbox.setText(htmlStr)

Is there any change, how to make overline text ?

Thank you for answer

@Noushin - of course; HTML is not multi-line by default, as you will notice if you prepare a multi-line HTML file and load it in your browser. To separate lines, you can use the HTML

or
tags. The W3Schools website is a good reference & tutorial for HTML and related technologies.

Hi
Thank you very much for the useful info. In my GUI, I first read a long string from an editbox (multiple lines) and then I’d like to change the font color of a portion of this text and display it in the same editbox. I’m not familiar with HTML coding but that’s what I did using your example above:

hEditbox=handles.my_editbox;
jScrollPane = findjobj(hEditbox);
jViewPort = jScrollPane.getViewport;
jEditbox = jViewPort.getComponent(0);
jEditbox.setEditorKit(javax.swing.text.html.HTMLEditorKit);
htmlStr = [str_part1,'', str_part2,'', str_part3);
jEditbox.setText(htmlStr);

the formatted string is displayed in the editbox however, it is no longer divided nicely between multiple lines! There is a very long first line where most of the string is out of the right margin. I was wondering is there is another setting that I need to tune for this to be properly displayed?

I appreciate your help, Noushin

Regular Matlab uicontrols do not support syntax hiliting – you need to use one of the controls I mentioned in http://undocumentedmatlab.com/blog/syntax-highlighted-labels-panels/

Hello,
it’s possible to set this property (Matlab Syntax) in a uicontrol type text?
thanks.

Thank you!

Best regards

Camilo

@Youlian and any other reader interested in syntax highlighting – I posted an expanded article about this topic in http://undocumentedmatlab.com/blog/syntax-highlighted-labels-panels/

Hello Yair,

thank you very much for your fast response. The code you posted worked quite well, with one exception, which is probably Matlab version dependent. The statement:
codeType = com.mathworks.widgets.text.mcode.MLanguage.M_MIME_TYPE;

led in Matlab 2008b to the following Matlab error:
??? Undefined variable “com” or class
“com.mathworks.widgets.text.mcode.MLanguage.M_MIME_TYPE”.

Instead of it I used:
codeType = com.mathworks.widgets.SyntaxTextPane.M_MIME_TYPE;

I tested it in Matlab 7.1, 2006b, 2007a and 2008b and it worked well.

Thank you very much once again!

Best regards

Youlian

@Youlian – Yes it is possible. Here’s a short code snippet demonstrating this (I will provide more details and other possibilities in an article sometime in the upcoming weeks):

jCodePane = com.mathworks.widgets.SyntaxTextPane;
codeType = com.mathworks.widgets.text.mcode.MLanguage.M_MIME_TYPE;
jCodePane.setContentType(codeType)
str = ['% create a file for output\n' ...
       '!touch testFile.txt\n' ...
       'fid = fopen(''testFile.txt'', ''w'');\n' ...
       'for i=1:10\n' ...
       '    % Unterminated string:\n' ...
       '    fprintf(fid,''%6.2f \\n, i);\n' ...
       'end'];
str = sprintf(strrep(str,'%','%%'));
jCodePane.setText(str)
jScrollPane = com.mathworks.mwswing.MJScrollPane(jCodePane);
[jhPanel,hContainer] = javacomponent(jScrollPane,[10,10,300,100],gcf);

SyntaxTextPane panel (Matlab MIME type)
