Special characters in DCL labels

I'd like to use "greater than or equal" in a radio button label. DCL
doesn't seem to like unicode. Is there a way to use unicode in a DCL
label? Any help would be appreciated.

Bill,

Thanks. Regular text is no problem. I have a situation where I need to
set a temperature range, and I have very limited space in the dialog
box. Being able to insert a "less than or equal" would make the
selection technically correct and would fit the space available.
Changing the screen font is not an option, and the "less than or equal"
symbol appears to be available only as unicode, based on the Windows
character map.

Can't you just concantenate it with the rest of the string?


(strcat (chr 60)(chr 61) "TEMP")


Bill

 

Sure. No strcat is necessary for that: (print "<= 140ºF") will do
that. What I'm after is the single character "less than or equal",
which is at \U+2264. It's mostly aesthetics....

(strcat "\U+2264" rest_of_txt)

Disgard that. Only works for text inserted in .dwg - not
in 'ascii' range for 'text' in a DCL file.
To see what I mean, do a Text in drawing, make it "AA".
Edit the text and change to "\U+2264AA".
Should show the <= symbol as 1st character.
When 'text' or 'label' applied in a .DCL, the .dcl file is just
'plain' text of range 32-128.......and doesn't know how to
handle the unicode.

Thanks, but I get an error on the label line with:

: radio_button
{
key = "30deg" ;
label = (strcat "\U+2264" "140°F");
}

The error report is:

====== DCL semantic audit of fd.dcl ======

Warning in "fault_drop". (widget type = radio_button, key = "30deg")
Attribute 'label' has a value of the wrong type.
It should be a quoted STRING.


label = "\U+2264 140°F"; labels the radio button as '\U+2264 140°F'.
Am I missing something in the syntax?

Martin

 

Ya,
Sorry bout that, read my last post.
Bob

 

Ah,

I see the unicode is "less than" with an underbar....


Bill

 

One way to do this would be to use an image tile. Draw the symbol, make a
slide, then display the slide in your dialog with the same background color
as the dialog to make the boundary and background disappear. If you make it
small enough, it could work. It's not a very elegant solution, but it could
work.

You won't believe this one.

label = "&<TEMP"

Bob

 

You won't believe this one.
<<<

I believe it Bob.

But really all you did was make the back arrow be the mneumonic character.


Bill

 

Well...
Just avoid using that Mneumonic

Bob

 

Just avoid using that Mneumonic<<

Well using the mneumonic wouldn't be the problem , esp being the it's the "label" of a radi button.

The limitation would be that you can only do it in the dcl and not the set_tile or concantate it into a run time variable.

But good idea for a fixed label.
