%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
%D This style is derived from the ninth style, which was
%D used first at \EUROTEX\ 99 and later at \TUG\ 2000. This
%D alternative build up a page.

%D We use blue colors instead of yellow ones. Since we have
%D used symbolic names, we can easily overload the existing
%D scheme.
\definecolor[LineColor][r=.40,g=.40,b=1.00]
%D Here we don't use fixed dimensions, but fit the sample
%D windows and derive the text windows's width from this one.
\setupframedtexts
[SampleText]
[width=fit,height=fit,
background={background,nextpage}]
%D The topic goes to the top right corner of the screen which
%D means that it is positioned left down to the reference
%D point. Watch how we make data on this layer (here only
%D the topic but it can be more) persistent.
\setuplayer
[topic]
[y=0pt,x=\makeupwidth,location=lb,state=repeat,
hoffset=-\FrameSkip,voffset=\FrameSkip]
%D Clicking on the page brings us back.
\setupbackgrounds
[page]
[background={previouspage,color,topic}]
%D All layers end up on the text area. This could have been
%D the page area too since these have the same dimensions.
\setupbackgrounds
[text]
[background={common,sample,text}]
%D Because we build up the text window step by step, we will
%D separate the entries by white space.

%D The \type {\Topic} commands can be simplified to:
\def\Topic#1%
{\resetlayer[topic]
\setlayer[topic]{\bfb\setstrut\color[TextColor]{#1}}}
%D We also provide a way to erase the topic.
\def\NoTopic
{\resetlayer[topic]}
%D We have to redefine the structuring commands to support
%D the resetting of buffer counters.

\def\StartSample

\stopstandardmakeup}
\def\StopSubText
{\startstandardmakeup

%D The \type {\DoSampleText} command is adapted to support
%D addition of subtexts (each subtext goes into its own
%D buffer).

%D Since we are no longer swapping windows, we end up with a
%D much simplier \type {\Stopidea} macro. We don't reset
%D samples at the inner level.

%D Here we determine the width of the text window. It is
%D derived from the width of the sample and stays the same
%D within a sequence.
\def\SetTextWidth
{\ifnum\TextN<1 % yes or no, may change
\scratchdimen=\makeupwidth

%D We use the (already implemented) second alternative of

\defineoverlay[joke] [\useMPgraphic{joke}{n=1}] % not to be changed !
\doifnotmode{demo}{\endinput}
%D The demo section. The original presentation uses proper

\StartIdea
\StartSample
\SomeSymbol{7cm}{1}
\StopSample
\StartText
This symbol can be used to indicate a hyperlink to a
previous page.
\StopText
\StopIdea
\StartIdea
\StartSubText
As one can expect there is also a symbol for going to
the next page.
\StopSubText
\StopIdea
\Topic{Previous}
\StartIdea
\StartSample
\SomeSymbol{9cm}{2}
\StopSample
\StartText
This symbol is actually just a mirrored version of the
first symbol we showed.
\StopText
\StopIdea
\NoTopic
\StartText
Is this nice or not?
\StopText
\Topic{First and Last}
\StartSample
\SomeSymbol{11cm}{3}
\StopSample
\StartSample
\SomeSymbol{11cm}{4}
\StopSample
\StartIdea
\StartSample
\SomeSymbol{5cm}{3}
\StopSample
\StartText
A few screens back, we saw this symbol.
\StopText
\StopIdea
\StartIdea
\StartSubText
This symbol represents the beginning of something.
\StopSubText
\StopIdea
\StartIdea
\StartSample
\SomeSymbol{5cm}{4}
\StopSample
\StartSubText
Just like this one represents an end.
\StopSubText
\StopIdea
\StartIdea
\StartSubText
They look just like the symbols found on audio and
video players.
\StopSubText
\StopIdea
\Topic{Summary}
\StartIdea
\StartSample
\SomeSymbol{6cm}{1}
\StopSample
\StartText
So we have a symbol for previous \unknown
\StopText
\StopIdea
\StartIdea
\StartSample
\SomeSymbol{6cm}{2}
\StopSample
\StartSubText
\unknown\ and one for next \unknown
\StopSubText
\StopIdea
\StartIdea
\StartSample
\SomeSymbol{6cm}{3}
\StopSample
\StartSubText
\unknown\ and yet another for first \unknown
\StopSubText
\StopIdea
\StartIdea
\StartSample
\SomeSymbol{6cm}{4}
\StopSample
\StartSubText
\unknown\ and of course for last.
