How to do this in ConTeXt

How to do this in ConTeXt

[R S Ananda Murthy]

Hello,

I need the format shown below:

-------------
|Example 1-1|
-----------------------------------------

Here Example 1-1 should be in a black box and text should be in white.
The line attached to this box should run up to the right margin.
I need a counter for examples to count up and display the example number
as shown above for more examples. I am new to ConTeXt. So, I need help.

Thanks for your help.

Anand

Here is (almost) what you want to acheive, but without any macros:
\blank
\starttext
%\def\Ex#1{ \line{\framed{\red #1}} }
\line{
  \framed[background=color,backgroundcolor=black]{
    { {\white Exemple 1.1\ }}}\hfill
  }
\hrule
\blank
To have numbers, you should use ennumeration.. And a try.. but I don't 
know how to adjust things... Others have to complete...

\defineenumeration[Exemple][location=serried,headstyle=bold,width=broad,
     text={\framed[background=color,backgroundcolor=black]{\red\sc 
Exemple}\textrule},margin=0.5cm,before=\blank,after=\blank]

\startExemple
This is a nice exemple.
\stopExemple


This is the end.
\stoptext

one of you has to wikify this answer ...

\setupcolors[state=start]
\setupbackgrounds[text][text][background=color,backgroundcolor=red,backgroundoffset=3pt]

\defineenumeration
  [example]
  [way=bychapter,
   separator=\compoundhyphen,
   chapternumber=yes,
   color=white,
   command=\exampleframed]

\defineframed
  [exampleframed]
  [background=color,
   backgroundcolor=white,
   foregroundcolor=black,
   style=bold,
   frame=off]

\starttext

\chapter{One}

\input tufte

\startexample
    \input tufte
\stopexample

\input tufte

\stoptext

Hi,

    Hans, it's so instructive to read yout post... I have learned from 
this last post 2 new commands !
However, I think the original poster wish a line who run to the right 
margin, so I added to your code
in the "defineenumeration" a "inbetween=\vskip-4pt{\hrule height 
1.5pt}\blank". This is not very elegant,
but this works. By the way, I'm interested to know if there is a better 
solution.

I'm not sure how to do this, but I can try how this works.
The complete code follows.
FL.

\setupcolors[state=start]
\setupbackgrounds[text][text][background=color,backgroundcolor=darkred,backgroundoffset=3pt]

\defineenumeration
  [example]
  [way=bychapter,
   separator=\compoundhyphen,
   chapternumber=yes,
   color=white,
   command=\exampleframed,
   inbetween=\vskip-4pt{\hrule height 1.5pt}\blank]

\defineframed
  [exampleframed]
  [background=color,
   backgroundcolor=black,
   foregroundcolor=white,
   style=bold,
   frame=off]

\starttext

\chapter{One}

\input tufte

\startexample
    \input tufte
\stopexample

\input tufte

\stoptext

if you say \showstruts you will notice why you need to skip back; your 
4pt is a gamble, best do something:

\defineenumeration
 [example]
 [way=bychapter,
  separator=\compoundhyphen,
  chapternumber=yes,
  color=white,
  command=\exampleframed,
  inbetween=\setups{example:inbetween}]

\startsetups example:inbetween
    \removedepth     % nils strut depth
    \nointerlineskip
    \blackrule[height=1.5pt,width=\hsize,depth=0pt]
    \blank
    \nobreak
\stopsetups

btw, this makes a nice example for a regression test
