Overscore Tabs in Mtext

AutoCAD 2005

Seems you can underline a 'tab character'
but you can't overscore it.

(setq
ms
(vla-get-modelspace
(vla-get-activedocument
(vlax-get-acad-object))))

(setq p (vlax-3d-point '(0 0 0)))

; works
(vla-addmtext ms p 0.0 "abc{\\L\t}def")

; doesn't work
(vla-addmtext ms p 0.0 "abc{\\O\t}def")

; works
(vla-addmtext ms p 0.0 "abc{\\Osome-other-characters}def")

Anyone know of a work around?

 

Jason,

I ran your code snip and noticed that regarding the overscore Mtext
example, the overscore *is* present but is displayed as just a small
speck (you have to look closely). If you use a font like Arial, the
speck becomes larger but still is not acceptable.

Don't have a solution for you. But just for your information, I also
tried the formatted string below, which doesn't use the curly braces for
grouping. Thought maybe that might help but no. Go the same results as
you did.

; Still doesn't work
(vla-addmtext ms p 0.0 "abc\\O\t\\odef")

So perhaps it is futile to try to generate the overscore if the Font
doesn't like to overscore a Tab character (don't know for sure).

Hi Steve,

I checked a couple of different fonts but didn't
see the spec you are referring to, nonetheless it
doesn't do what I need it to do.

For this particular application I might be able to
introduce a line of tab characters above what I
wan't overscored, and use an underline on those
tabs instead. Don't really like the idea, but if it
will work....

Thanks for taking a look at this.

 

Hello Jason,

You're welcome. I should have added to my previous post that the fonts I
was using was Txt.shx and Arial.ttf

Don't know why you didn't see the teeny tiny overscore; I had to zoom
extents to the single Mtext entity.

Maybe if Dave from TC Fonts is watching, he could give us a better
explanation to this tab formatting issue.

I went back and tried the txt.shx and Arial.ttf
and didn't see the spec.... Possibly different
versions of these fonts? Good thought on Dave,
Dave? you out there?
