The following macro places the title right

\unexpanded\def\HeadTitle#1#2%
  {\framed
    [frame=off,
    width=broad,
    align={broad,nothyphenated,left}]
    {#1\blank#2}}

I wish the chapter title on right of the page. The numbering of the chapters is fixed at 0, why ?
thank you,
Fabrice



\unexpanded\def\HeadTitle#1#2%
  {\vbox \bgroup
   \setupframed[offset=0.5em,frame=off]
   \inframed[width=fit,align=right]{#1}%
   \inframed[width=fit,align=right]{#2}%
   \egroup}


\startusableMPgraphic{chapter}
      picture r ;
      r := image ( graphictext
        \MPstring{chapter}
        scaled 3pt
        withfillcolor \MPcolor{lightgray}
        withpen pencircle scaled 1pt ; ) ;
      draw r ;
    \stopusableMPgraphic

\unexpanded\def\processMPheadnumber#1%
  {\setMPtext{chapter}{\bf#1}
   \useMPgraphic{chapter}}

\setuphead
   [chapter]
   [command=\HeadTitle,
    numbercommand=\processMPheadnumber{\currentheadnumber}]

Thank you Hans, the code would be :

\unexpanded\def\HeadTitle#1#2%
  {\hbox to \hsize \bgroup
   \hfill
   \setupframed[offset=0.5em,frame=off]
   \inframed[width=fit,align=left,frame=off]{\darkred#1}%
   \inframed[width=fit,align=right,leftframe=on,rulethickness=4pt,framecolor=darkred]{#2}%
   \egroup}

Thank you Hans, the code would be:
Could I ask you how to have the chapter number is like the http://www.pragma-ade.nl/general/manuals/cont-enp.pdf book?
This is a macro Metafun but I do not quite understand the mechanism.
thank you,
Fabrice

Hello,
In the manual, there is the macro below.
Why theword "Matrice" is not on the same baseline as the number "1" ?
thank you,
Fabrice

\unexpanded\def\HeadTitle#1#2%
  {\hbox to \hsize \bgroup
   \setupframed[height=1cm,offset=0.5em,frame=on]
   \framed[width=fit,align=left]{\darkred#1}%

\framed[width=fit,align=right,leftframe=on,rulethickness=4pt,framecolor=darkred]{#2}%
    \egroup}

\setuphead
   [chapter]
   [command=\HeadTitle]

\starttext

\startchapter
  [title={Matrice}]


\stopchapter

\stoptext

fonts and such ... better use:

\unexpanded\def\HeadTitle#1#2%
  {\hbox to \hsize \bgroup
   \inframed[width=fit,align=left]{\darkred#1}%

\inframed[width=fit,align=right,leftframe=on,rulethickness=4pt,framecolor=darkred]{#2}%
   \egroup}
