Thread Subject: waitbar TeX warning

Is there a way to stop the following warning from appearing without
hacking the waitbar function?

>> filename = fullfile('path', 'file')

filename =

path\file

>> waitbar(0.1, sprintf('Processing %s', filename))
Warning: Unable to interpret TeX string "\file".
> In waitbar at 188

It doesn't have any effect on the waitbar appearance, but it's a bit
annoying that the warning keeps appearing. I can stop it by turning
off the interpreter in the waitbar function,

tHandle=title(name); % original line 188
tHandle=title(name, 'Interpreter', 'none'); % new

but I'd rather something I could switch off only when needed, rather
than permanently disabling TeX. Is there a way to do this without
actually rewriting waitbar to accept a new input?

Hi,

See the MATLAB TeX reference doc page, you have to avoid \file which may be
tentatively interpreted by replacing any \ by \\.
" To print the special characters used to define the Tex strings when
Interpreter is Tex, prefix them with the backslash "\" character: \\, \{, \}
\_, \^. "


% One of the possible way to avoid the warning.
filename=fullfile('path','file');
TexFileName=strrep(filename,'\','\\');
waitbar(0, sprintf('Processing %s', TexFileName))
%
Please note that since Tex interpretor is not disable, special symbol or
typo are possible to display

The text interpreter can be modified by locating where that
property in the heirechy of objects. For the statement

   hwait = wait('Some message');

Run the program to that statement in your code, then
examine hwait with

   get(hwait).

hwait doesn't have a Interpreter property, so look at the
children.

   hchild = get(hwait,'children');
   get(hchild);

hchild also doesn't have an Interpreter proprety, but does
have a title property, which is set in the waitbar
function. Look at the properties of title.

   htitle = get(hchild,'title');
   get(htitle);

Here, the Interpreter property is set to Tex. Change it
with

   set(htitle,'Interpreter','None');

In your code, enter the following commands to set the
Interpreter to none.

   hwait = wait('Some message');
   hchild = get(hwait,'children');
   htitle = get(hchild,'title');
   set(htitle,'Interpreter','None');
