orphan headline

[Andrea Valle]

[-- Attachment #1.1: Type: text/plain, Size: 1994 bytes --]

Dear all, 

I’m finishing a book, and getting the following undesired result.
Many times I have section or subsection title at the bottom of a page, with no text. Text starts on the next page.
I have looked at 

http://wiki.contextgarden.net/Widows_and_orphans_control

but I wasn’t able to solve.

I guess it could depend on the formatting of my headlines. Here they are: 

\setuphead[section]
[style=\ss\tfa, before={\blank[0.5cm]\startframedtext[offset=0.25cm,framecolor=black,
rulethickness=0.01cm, frame=off, topframe=off,  bottomframe=on]\crlf},after={\stopframedtext\noindentation\blank[1cm]}]

\setuphead[subsection]
[style=\ss, before={\blank[0.5cm]\startframedtext[offset=0.25cm,framecolor=black,
rulethickness=0.01cm, frame=off, topframe=off,  bottomframe=on]\crlf},after={\stopframedtext\noindentation\blank[1cm]}]

thanks 

Best

Hi Andrea,

you may replace \blank[1cm] with \blank[samepage,1cm].

This should move the heading to the next page.

Just in case it helps,

Pablo

In a much simpler case, it seems to work:

    \setuphead[section]
    [style=\ss\tfa, after={\hrule\blank[samepage,big]}]
    %~ [style=\ss\tfa, after={\hrule\blank[big]}]

    \setuphead[subsection]
    [style=\ss, after={\hrule\blank[samepage,medium]}]
    %~ [style=\ss, after={\hrule\blank[medium]}]

    \starttext
    \dorecurse{10}{\section{Section}
    \input knuth
    \subsection{Subsection}
    \input zapf}
    \stoptext

Do you really need headings to be inside framed texts?

Your lack of a working minimal example makes it hard to give a solution
but adding changing the way how the frame is added should improve things.

\startsetups[section:andrea]
     \ifconditional\headshownumber
         \scratchdimenone\dimexpr\headnumberwidth+\headnumberdistance\relax
         \scratchdimentwo\dimexpr\headnumberdistance\relax
     \else
         \scratchdimenone\zeropoint
         \scratchdimentwo\zeropoint
     \fi
     
\startframedtext[offset=0.25cm,loffset=\scratchdimenone,rulethickness=0.01cm,frame=off,bottomframe=on]
         \dontleavehmode\llap{\headnumbercontent\hskip\scratchdimentwo}
         \headtextcontent
     \stopframedtext
\stopsetups

\defineheadalternative[section:andrea][alternative=vertical,renderingsetup=section:andrea]

\setuphead
   [section]
   [alternative=section:andrea,
    numberwidth=1em,
         before={\blank[0.5cm]},
          after={\blank[1cm]}]

\starttext

\section{\input ward }

\subject{\input ward }

\stoptext

Sorry, I know, but I didn’t know to reproduce the situation.

look likes it solves all the problems! I really have no idea of what’s going on here. Luckily this mailing list is super friendly.
Manuals are cool, but I always miss the big picture that would allow me to generalise over a problem!


Thanks

A good idea but it can be improved.

\definevspace[sectionrule][3mm]

\setuphead
   [section]
   [       width=0.8\textwidth,
    commandafter={\vspace[sectionrule]\hrule},
          before={\blank[0.5cm]},
           after={\blank[1cm]}]

\starttext

\section{\input ward }

\subject{\input ward }

\stoptext

Wolfgang,

many thanks for the improvement.

I have a question about your code:

What prevents page break between heading the next paragraph?

I might guess that is the two distinct options commandafter and after.
But this is only my suspicion on what may work there.

Many thanks for your help,

Pablo

a rather complex method of weighted penalties that also needs to make 
sure we don't break between successive heads but at the same time makes 
sure that we don't overflow the page
