Hi!
How do I highlight the current chapter in the table of contents? The
TOC is displayed on each page. For illustration I misused the
interaction colour, which of course only works for the first page of
a chapter.
\setupheadertexts
[\setups{headlist}]
\startsetups [headlist]
\framed[align=normal, frame=off]
{\placelist [chapter] [alternative=f, criterium=all]}
\stopsetups
\setupinteraction
[state=start,
color=lightgray,
contrastcolor=darkgreen]
\starttext
\startchapter [title=alpha] \stopchapter
\startchapter [title=beta] \page\input knuth \stopchapter
\startchapter [title=gamma] \stopchapter
\stoptext
Marco

The problem for the solution below is to get a expandable version of the list entry because \currentlistentrytitle itself isn’t expandable and can’t be used in \doifelse. Instead of using \ctxcommand better ask Hans for a raw/expandable version of the tile/pagenumber commands. \setupheadertexts [\setups{headlist}] \startsetups [headlist] \framed[align=normal, frame=off] {\placelist [chapter] [alternative=highlight, criterium=all]} \stopsetups \definelistalternative [highlight] [renderingsetup=list:highlight] \startsetups [list:highlight] \par \startlinealignment[middle] \doifelse{\fetchmark[chapter][first]}{\currentlistentrytitle} %\doifelse{\fetchmark[chapter][first]}{\ctxcommand{listtitle("\currentlist",\currentlistindex)}} {\color[red] {\currentlistentrytitle}} {\color[blue]{\currentlistentrytitle}} \stoplinealignment \par \stopsetups \setupinteraction [state=start, color=lightgray, contrastcolor=darkgreen] \starttext \startchapter [title=alpha] \stopchapter \startchapter [title=beta] \page\input knuth \stopchapter \startchapter [title=gamma] \stopchapter \stoptext Wolfgang ___________________________________________________________________________________ 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] 16+ messages in thread

Is this a good description of the command's behavior? All structure heads, regardless of level, get a location number in the order in which they appear. Like so (see also MWE at bottom of this e-mail): \section{Alpha} % location number: 1; type: section; section number: 1 \section{Beta} % location number: 2; type: section; section number: 2 \subsection{Aap} % location number: 3; type: subsection; subsection number: 1 \subsection{Noot} % location number: 4; type: subsection; subsection number: 2 \section{Gamma} % location number: 5; type: section; section number: 3 \namedstructureheadlocation{X} then returns the location number of the current X, where X is the name of a structure level (e.g. 'chapter', 'section', etc.) If you ask for e.g. \namedstructureheadlocation{chapter}, and you are not in a chapter, then 0 is returned. Anything missing? @Marco: sweet job on http://wiki.contextgarden.net/Command/definelistalternative. I have taken the lazy liberty of redirecting Command/currentlistentrylocation Command/structureheadlocation Command/currentlistentrynumber etc to that page for the now, so that they at least appear in the list of commands. --Sietse \starttext \startsection [title=alpha] \stopsection \startsection [title=beta] \startsubsection[title=aap] \namedstructureheadlocation{section} \namedstructureheadlocation{subsection} \startsubsection[title=noot] \namedstructureheadlocation{section} \namedstructureheadlocation{subsection} \stopsubsection \stopsection \startsection [title=gamma] \namedstructureheadlocation{section} \stopsection \stoptext ___________________________________________________________________________________ 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] 16+ messages in thread

A predefined alternative works perfectly in a layer. Header and footers are added and calculated after the page is finished but when you put a text in a layer it is fixed at this moment. The problem in your example with the custom list alternative is that you haven’t defined it when it is needed, when you put \definelistalternative and \startsetups … \stopsetups before \setlayer you can see it. For a dynamic layer take a look at this wiki page: http://wiki.contextgarden.net/Layers#Use_dynamic_content Wolfgang ___________________________________________________________________________________ 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] 16+ messages in thread

In most cases, metapost is sufficient for drawing backgrounds, but occasionally using tikz is nicer. For example, when tikz provides a solution that is not available in metapost (e.g., drawing "snake" paths), or extremely difficult to get right in metapost (drawing shadows). As Hans said, overlays can be used for anything, including tikz background. Here is a proof of concept implementation: \usemodule[tikz] \usetikzlibrary[decorations.pathmorphing] \def\TIKZdecorationoverlay {\starttikzpicture \expanded{\draw[\overlaylinecolor, line width=\overlaylinewidth, decorate, decoration={\framedparameter{decoration}}] (0,0)--(\overlaywidth,0) -- (\overlaywidth,\overlayheight) -- (0,\overlayheight) -- cycle;} \stoptikzpicture} \defineoverlay[decoration][\TIKZdecorationoverlay] \setupframed [decoration=snake] \starttext \framed[frame=off, rulethickness=3bp, background=decoration, backgroundoffset=3mm, framecolor=red, align=normal] {\input ward \endgraf} \blank[2*big] \externalfigure [cow] [frame=off, frameoffset=5pt, backgroundoffset=frame, background=decoration, decoration={coil, amplitude=4pt, segment length=5pt}] \stoptext Aditya ___________________________________________________________________________________ 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] 16+ messages in thread
