\setupitemize[afterhead=...] not working

\setupitemize[afterhead=...] not working

[Peter Münster]

Hello,

The parameter "afterhead" seems to be ignored (MKII and MKIV):

\setupitemize[afterhead=:]
\starttext
\startitemize
\txt{bla} bla
\stopitemize
\stoptext

Cheers, Peter

There is no \head in your numeration.

Try:

\def\aftercolon{\groupedcommand{}{:}}
\setupitemize[headstyle=\aftercolon]

Indeed, but "headstyle" applies nevertheless.

Thanks, nice workaround!

Yes, this is how \txt is defined

\appendtoks \letvalue\v!txt  \itemgrouptext  \to \itemgroupcommands

\def\itemgrouptext#1%
{\def\symsymbol{\doitemattributes\currentitemlevel\c!headstyle\c!headcolor{#1}}%
    \settrue\symbollistitem
    \settrue\txtlistitem
    \itemgroupitem}

So, headstyle and headcolor are used, but not afterhead. Actually, is you 
use \head, the result is interesting :)

\setupitemize[afterhead=:]
\starttext
\startitemize
   \head This is a test

     what happens here
\stopitemize
\stoptext

Certainly not what I would have expected.

It is what you expect after you have read the definition but funny for
the first moment.

@Peter: afterhead is meant for vertical material like skips, rules
etc. or you could
use to draw a frame around the itemize head.

Ok, so afterhead applies only to the \head command. I've chosen \txt{},
because I need something like this:

\setupitemize[headstyle=\bf\groupedcommand{}{:}, width=5em, distance=1em]
\starttext
\startitemize
\txt{Short}
\input tufte
\txt{Very very very long}
\input tufte
\stopitemize
\stoptext

Should \head better be used for this purpose? And if yes, how?

Cheers, Peter

You should better use descriptions, this is what your example looks
like and what I guess only by looking at the output.

Indeed, but I don't know how to do that with descriptions... :(

Me too, I come close to what do you want but two problems remain,
it's no possible to set a minimum width for the label and a unwanted
space is between the end of the head text and the colon.

\definedescription
  [peter]
  [align=left,
   location=hanging,
   margin=5em,
   width=broad,
   command=\groupedcommand{}{:}]

\starttext

\peter{Short}
\input tufte

\startpeter{Very very very long}
\input tufte
\stoppeter

\stoptext

Regards
Wolfgang
