Change TITLE font size of the message box.

Hello,

I'm trying to change the TITLE font size of the message box I created.

I wrote the following:

CreateStruct.Interpreter = 'tex' ;
CreateStruct.WindowStyle = 'modal' ;

waitfor (msgbox ( '\ fontsize {15} Check for font size.' , '\ fontsize {15} Testing ...' , 'help' , CreateStruct));

which worked perfectly for the text (message). However the same cannot be said for the title.

I'm wondering why it is not applicable for the title, once the structure is exactly the same and the MATLAB documentation says that if the interpreter value is 'tex', MATLAB interprets the message and title values ​​as tex.

Any suggestions on how to solve this, would be appreciate.

Thanks in advance.

You need to removed the spaces for the fontsize commands to work in the main body of the msgbox.

msgbox ( '\ fontsize {15} Check for font size.' , ...
% Remove   ^        ^

The interpreter does not affect the title of the msgbox which is really just the figure name.

Hey Adam,

thanks for your comment.

Actualy these spaces were done automatically when I transfer the code to here. These spaces are not like this in the tests I did (real code).

And, even removing the spaces, the changes are not yet applicable to the title of the msgbox, only to the message (text - central body of the msgbox).

I don't know why the same idea cannot be applicable for the title of the message box, since MATLAB's own doccumentation says that this is possible.

What version of MATLAB are you using?

[THULYO NEDER]

R2018b.

[Adam Danz]

The r2020b documentation does not state that the interpreter will be applied to the title

"If the Interpreter value is 'tex', MATLAB interprets the message value as TeX"

The title is just the figure name and the figure does not have an interpreter property.

[THULYO NEDER]

It is R2018b, not R2020b.

[Adam Danz]

I see where the 2018b documentation mentions that but I'm fairly certain it was a mistake that has since been corrected. I remember creating a function to control the fontsize of msgbox back in 2018 and could not make it apply to the title text (aka, figure name).

Ok, Adam.

You must be right about this issue. Maybe this is a mistake in the documentation, once it is not applicable for the title.

Anyway, thank you very much for your attention and clarification.

I'm pretty sure you cannot format the text in the title bar. The formatting here is set by the operating system. You can set the text, but not the properties (i.e. font style, color, size, type, etc).

Ok, Cris.

Anyway, thanks for your attention and clarification.
