greek symbols in GUI

Jonas — Sat, 27 Oct 2007 22:24:17 -0400

Hello, I'm building a GUI and I like to know how to get a
greek symbol for example in a static text or in a push
button. I'd then like to write

set(handles.static_text,'String','\alpha')

to display the greek letter alpha but this doesn't work.
Thanks!

There is a submission on the file exchange for doing this
at http://www.mathworks.com/matlabcentral/fileexchange/
loadFile.do?objectId=10743&objectType=file

Yes, that is one way to do it, although it is easy to run
the function i wonder if there is a simpler way to do it?

If all you want is Greek letters then you can just use the Symbol font:

set(handles.static_text,'String','a','FontName','symbol')

Well, I also need subscript letters so that I can write a
variable with its index.

Well, that's okay because the Symbol font has normal numbers. It should
look fine.

But what about a letter in normal size plus a subscript.
For example to get a title for a plot with subscripts one
would write

title('E_\theta');

So is there any simple way of doing this for a GUI control
such as in a static text? Or is this really a limitation in
GUI controls?

No, there's no simple way. UIcontrols don't use the tex or latex
renderers, I don't know why. Anyway, that's why I wrote uibutton. Just
use that.

You can use an undocumented feature of all Matlab
uicontrols, which is the fact that they use underlying Java
Swing controls, and these in turn accept any valid HTML
strings. So you can do the following for example:

uicontrol('string','<html>12345</html>')

This is equivalent to the tex string '\bf1_23^45\rm'. You
can set font faces, colors, sizes, bold/italic and any other
valid HTML 3.0 property. It's limited, but should do the
trick in most conceivable cases.

The same is true for tooltips, by the way: try setting
multi-line ( ) multi-colored ( ...
) tooltip once and you'll never use the standard
boring single-line black tooltip again...

And just in case you were wondering - yes, it also works for
menus, listboxes etc.

Hello, this was a great feature I didn't know about.
However, this works with every uicontrol except with static
text, the one I needed. So I guess the text uicontrol
doesnt' have this underlying Java Swing control. But thanks
to all of you who tried to help.

Try

uicontrol(['string','<html>π</html>'])

and use a decimal value for the stuff between the html tags.
You'll get a pi button.

The values can be found at the handy chart at
http://htmlhelp.com/reference/html40/entities/symbols.html

I just wish it would work for disp() too.

Hello,

The java syntax '<html>&lambda</html>' works great on the
recent MATLAB version with greek lambda.

But it does not work on a GUI fig created by 2006B version:
The text appears as it is on the screen:'<html>
&lambda</html>'. Is there a way to make it work on 2006B?

Thanks,

Bruno

Type Correction:

uicontrol('string','<html>π</html>')

Hi,
Is it possible to make a string for static txt not only with greek letters, ie Impedance (Ω) using the symbol font? Any other alternatives?

Thanks

Of course it is possible: http://undocumentedmatlab.com/blog/customizing-matlab-labels/
