Itemize columns with MPgraphics: another vertical spacing puzzle

Itemize columns with MPgraphics: another vertical spacing puzzle

Hi List,

I need to itemize graphics when I use those graphics as the choices in a multiple choice question. When I do that in columns, I am getting excess space below the graphics. See example code and output below. Any suggestions for how I get rid of this space?

I’m not sure if this is related to the itemize column spacing in my previous comment.

Thanks, again!
Gavin


\starttext

\defineitemgroup[choices]
\setupchoices [each] [A,joinedup] [left=(, right=), width=1.7em, stopper=,]
\define\choice{\item}

\def\mycolor{.625red}

\startuseMPgraphic{name}
  fill fullcircle scaled 40pt withcolor \mycolor;
\stopuseMPgraphic

\define[1]\mycolordot{\def\mycolor{#1}\framed[location=top,offset=0pt,frame=off]{\useMPgraphic{name}}}

What is your favorite color? (There is too much space after these choices.)
\startchoices[columns,four]
  \choice \mycolordot{.625red}
  \choice \mycolordot{.625blue}
  \choice \mycolordot{.625green}
  \choice \mycolordot{.625magenta}
\stopchoices

A ruledhboxs show the extra space is in the itemize, but not in the item contents.

\ruledhbox{\startchoices[columns, four]
  \choice \ruledhbox{\mycolordot{.625red}}
  \choice \mycolordot{.625blue}
  \choice \mycolordot{.625green}
  \choice \mycolordot{.625magenta}
\stopchoices}

Putting a ruledhbox around the first item shows that each item has extra space that is not part of the item contents. (The ruledhbox also messes with the horizontal alignment, but I don't care about that.)
\startchoices[columns]
  \ruledhbox{\choice \mycolordot{.625red}}
  \choice \mycolordot{.625blue}
  \choice \mycolordot{.625green}
  \choice \mycolordot{.625magenta}
\stopchoices

The extra space is not present without columns.
\startchoices
  \choice \mycolordot{.625red}
  \choice \mycolordot{.625blue}
  \choice \mycolordot{.625green}
  \choice \mycolordot{.625magenta}
\stopchoices

\ruledhbox{My favorite color is:\def\mycolor{.625blue}
    \framed[location=top,offset=0pt,frame=on] {\useMPgraphic{name}}}

Re: Solved! Itemize columns with MPgraphics: another vertical spacing puzzle

Hi List,

I solved this problem, but the solution is a bit mysterious to me. I was trying to solve another problem – removing the small space underneath the graphic in the framed box. I did this by adding boffset=-\strutdepth to the framed command. That not only got rid of the space inside the frame, it also removed the excess space between the rows in the itemize columns!

I don’t know why this fix solved both problems, but I’m happy with the result. Now I can use options for the choices – like packed and joinedup – with consistent results for any number of columns. I’ve put the fixed code and output below, for anyone who is interested.

Even when I’m a bit confused, I’m glad to be working with ConTeXt rather than any other system!

Best,
Gavin

Here are a few great looking multiple choice questions about colors.
\startquestions
\question What is your favorite color?
\startchoices[columns,four]
  \choice \mycolordot{.625red}
  \choice \mycolordot{.625blue}
  \choice \mycolordot{.625green}
  \choice \mycolordot{.625magenta}
\stopchoices

\question What is your least favorite color?
\startchoices[columns]
  \choice \mycolordot{.625red}
  \choice \mycolordot{.625blue}
  \choice \mycolordot{.625green}
  \choice \mycolordot{.625magenta}
\stopchoices

\question Toward which colors do you feel indifferent?
\startchoices[one]
  \choice \mycolordot{.625red}
  \choice \mycolordot{.625blue}
  \choice \mycolordot{.625green}
  \choice \mycolordot{.625magenta}
\stopchoices
\stopquestions

That's it for questions about colors!

% your hack:

\define[1]\mycolordot{\def\mycolor{#1}\framed[location=top,offset=0pt,boffset=-\strutdepth,xframe=off]{\useMPgraphic{name}}}

% but ... you just don't want struts

\define[1]\mycolordot{\def\mycolor{#1}\framed[location=top,offset=0pt,strut=no,frame=off]{\useMPgraphic{name}}}

% and no offset but also no invisible frame

\define[1]\mycolordot{\def\mycolor{#1}\framed[location=top,offset=overlay,frame=off]{\useMPgraphic{name}}}

playing with framed for a while alway spays back

Thanks, Hans!

That works, and it makes sense. Playing with frames always pays, indeed.
