That was fine until it ran into \setupwhitespace with a non-zero value.
Fiddling with the after key \blank does not appear to help.
\define[2]\MarginHead{\inmargin{#1\\#2}}
\setuphead [section]
[command=\MarginHead,
distance=0pt,
after={\strut\blank[-2*line,samepage,disable]}]
%% With no \setupwhitespace, or any \setupwhitespace setting that
%% results in zero interparagraph whitespace, all is well.
%setupwhitespace [none]% okay
%setupwhitespace [fix]% okay
%% With non-zero interparagraph whitespace, the heading separates
%% from the text
\setupwhitespace [line]% bad
\starttext
\startchapter[title={Weisman}]
\input weisman\par
\input weisman
\startsection[title={Thuan}]
\input thuan\par
\input thuan
\stopsection
\stopchapter
\stoptext

Meanwhile, the following works for non-grid layouts with reasonable values for \setupwhitespace, although perhaps somebody can come up with a more eloquent way to write it: \newdimen\SectionHeadSkip \SectionHeadSkip\dimexpr-2\lineheight-\parskip\relax \setuphead [section] [command=\SectionCommand, distance=0pt, after={\strut\blank[\the\SectionHeadSkip,samepage,disable,nowhite]}, ] \define[2]\SectionCommand {\inmargin{#1 -- #2}} When enabling grid layouts, the number of lines needs to be adjusted. Floats that appear as the first thing after a heading may present problems, especially with larger values for \setupwhitespace. (The default, with no location= specified, is pretty good, but when location={left,force} or such, there is often an unwanted offset from the header. and page breaks still appear between the heading and figure at times, despite the samepage setting for \blank.) So, this is quite fragile. It requires careful checking of every heading, and manual tuning when one breaks. Not a desirable solution, but at least it is possible. -- Rik Kabel [-- Attachment #1.2: Type: text/html, Size: 5184 bytes --] [-- Attachment #2: Type: text/plain, Size: 485 bytes --] ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 4+ messages in thread
