widow/orphan control in columns?
Hello, We have a document with a 2-column layout where we have section headers that keep ending up at the bottom of columns. E.g. \startsectionheading{2. Foo bar baz}\stopsectionheading where \startsectionheading is defined by: \definestartstop [sectionheading] [before={ \startalignment[middle]}, after={\stopalignment \bigskip}, style={\switchtobodyfont[...,...]}] In order to make sure this section heading gets followed by a line or two of actual text, I saw on web pages [1] and [2] that you can use \testpage[n] to check whether there is room for n more lines, and if not, to produce a page break. I checked the manual [3] and command reference [4] but couldn't find information about \testpage. Is there a corresponding command to conditionally produce a column break? Thanks, Lars [1] http://getfo.org/context_xml/page4.html [2] http://wiki.contextgarden.net/Layout [3] http://www.pragma-ade.com/general/manuals/cont-eni.pdf [4] http://texshow.contextgarden.net/

I just looked at the implementation of \testpage in base/page-ini.tex and found \testcolumn. I imagine that should be analogous to \testpage, but hesitate to rely on an undocumented feature, as it might be unused or obsolete code. I can't find any examples of anyone using \testcolumn. Yet it seems that keeping a section header with the following text in a column would be a common layout requirement; even Microsoft Word does it. Am I missing something? Does anybody know if \testcolumn is intended for public use? Thanks again, Lars

tex does not know about columns, so any implementation is kind of a hack; some time next year in mkiv we will have a more advanced skip/penalty model that might handle such cases

if it works for you ...

using \testpage in one column mode is ok; i use it often (if you look in the source you will notice that there are several strategies related to it) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
