presentations: help needed

[Eckhart Guthöhrlein]

Hello all,

I am preparing my first presentation with context, and I have some ideas 
which I simply can't get to work. Time is really short now and I like 
s-pre-01, so I decided to take this style as a starting point.
My document is structured into four main \Topic parts, each of which is 
devided into several \Subject parts.

1. I want the \Topic command to output nothing -- nor its title nor a list 
of subjects -- at the place where it is used. But I do want the titles to 
appear in the list of topics on the right of the screen.

2. Each topic is highlighted in the list on the right when the first page 
of the topic is reached, but not for subsequent pages belonging to the 
topic. I would like the current topic to be higlighted for every page.

3. \presentationstep does not have any noticable effect. This is the 
command to be used to build a page stepwise, isn't it? Like 
bla\par\presentationstep bla? How to do the trick?

Thank you very much for any help with these questions -- especially if they 
should have trivial answers (rather likely...).

Eckhart

ps: is there a setup command to change the default text colour including 
the colour of captions?

I suggest you take a look at s-pre-01.tex. This probably helps to
decide what to adapt, and what is easy and what is difficult.

Not easy I think.

A feature I would like to have too :-)

Look at s-pre-00.tex, there are some comments there which might help.

Again look at s-pre-01.tex which colors are used. Override with:

\definecolor[white][blue]

for example, or hack s-pre-01.tex

megs)

Yes, sorry, it was not that difficult. Now I have this file:

\input s-pre-02

\enablepresentationstep
\definereference[Whatever][JS(NextPresentation{\realfolio})]
\definecolor[StepColor][BackgroundColor]

\starttext

    \dorecurse{10}{This is some great text! }

    \presentationstep

    The even greater rest.

    \page

    Hallo

\stoptext

I get a stepwise result now.  Two problems remain, the first one very annoying:

1) The final line before \presentationstep gets cut at the baseline, 
resulting into truncated letters g, j etc.
This makes it unusable. In s-pre-00.tex I found
\def\dopresentationstep#1% not ok yet
   {...
       \def\presentationshade%
         {\presentationshield
            [\c!breedte=\tekstbreedte,\c!hoogte=\presentationstepheight]{}}
   ...}
I think the height has to be increased here (by the depth of a \strut)? I 
tried it and it worked ok for the text lines, but the shields overlap from 
the text into the page area. How to do it?

2) How to bind the Whatever reference to a key, the return key if possible? 
Any action that does a nextpage now should do a Whatever instead.
(probably very basic)

To be precise: I want to change the colour of the glyphs from black to 
something, not the colour of the background. I am sure there is a command 
for this, but I can't find it...

Yes, until now I have no real success. My best solution now is to set the 
head colour for \Topic to the background colour of the text area and 
skipping back with after=\vskip... - better to stop here, I already said 
too much, but it even works (kind of)...

So I guess you tried and didn't succeed. Which means that I am probably 
wasting my time if I try it after work tonight.

This gives me an idea:

Something like:

\setuphead
  [Topic]
  [command=\NoTopic,
   page=no,
   before=\relax,
   after=\relax]

\def\NoTopic#1#2%
        {}

This makes topic not skip to the next page, with \NoTopic I attempt to
do really nothing. There might be some white space though.

Take your choice: hidden titles, or extra list entries

\definehead[mytitle][chapter]

\setuphead[mytitle][placehead=no]

\starttext

\placelist[chapter,mytitle]

\chapter{test} test \page
\mytitle{test} test \page
\writetolist[chapter]{}{oeps}
\chapter{test} test \page

\stoptext

I tried this, but it makes the list of topics on the right disappear 
completely. Seems the title has to be typeset somehow to get to the list, 
and that's why I tried typesetting it invisibly (in the background color). 
Alas, thank you!

This is perfect, so this problem is solved now! I didn't suspect the 
placehead key to do exactly what I want, although it is in the list of 
parameters in the manual .

I have once defined something like:

\def\pagenull {\gdef\subjpage{\page}}
\setuphead[chapter][before=\page, 
                    after=\pagenull,
                    style=bold]
\setuphead[section][before=\subjpage]

This way, a new section starts with a page break, but not if it is the first 
of a chapter.

actually this is default behavior and can be controlled by the "continue" 
key (so there is page=yes,continue=yes by default for chapters)
