Thank's for your example! But I'm sorry to say, I didn't get it.
When I run context on it, it results in a 2x2 matrix of pictures.
Two of them show some reaction (change the color somewhat)
when I click on them. (the cows don't). That's all.
Maybe it has to with the following lines in the log file:
...
interaction : active
references : unknown reference [][VideLayer{1}]
references : unknown reference [][VideLayer{2}]
references : unknown reference [][VideLayer{3}]
references : unknown reference [][VideLayer{4}]
...
I tried the following example from the Wiki:
=======
\defineproperty[my-hasitations][layer][state=stop]
\startproperty[my-hasitations]
To \ConTeXt\ or not to \ConTeXt?
\stopproperty
\button{Show Decision}[VideLayer{my-hasitations}]
\button{Hide Decision}[HideLayer{my-hasitations}]
\button{Toggle Decision}[ToggleLayer{my-hasitations}]
========
This produces the analogous messages for these three buttons.
My Context Version - "MTXrun | current version: 2010.11.03 19:42"
My LuaTeX Version - This is LuaTeX, Version beta-0.63.0-2010090921
on Debian AMD64. I looked at the files with Acrobat Reader 9 on Windows XP
(BTW. I also tried this completely using a MiKTeX 9 Installation on WinXP
without
success)
Am I missing something?
kind regards

Dear Contexters! In the last few days I could read a few posts about "animations" in a resulting PDF document. Some statements mentioned java script as possible means to create an animation. Is it possible to do the following (which is rather simple using html and javascript)?
-- Have a bunch of thumbnail pictures -- When you click on a thumbnail you see a larger version of the same picture -- With the next mouseclick the picture vanishes (you see the gallery of thumbnails again)
if yes, how? Any hints are welcome.
Not perfect (it’s not possible to close the big pictures) but it should give you a first impression:
\setupinteraction[state=start]
\defineproperty [1] [layer] [state=stop,global=yes] \defineproperty [2] [layer] [state=stop,global=yes] \defineproperty [3] [layer] [state=stop,global=yes] \defineproperty [4] [layer] [state=stop,global=yes]
\starttexdefinition properties \startoverlay {\startproperty[1]\overlayfigure{cow}\stopproperty} {\startproperty[2]\overlayfigure{mill}\stopproperty} {\startproperty[3]\overlayfigure{hacker}\stopproperty} {\startproperty[4]\overlayfigure{cow}\stopproperty} \stopoverlay \stoptexdefinition
\defineoverlay[properties][\properties]
\startTEXpage[background={foreground,properties}]
\bTABLE[width=4cm,height=4cm,offset=none] \bTR \bTD \goto{\overlayfigure{cow}}[VideLayer{1}] \eTD \bTD \goto{\overlayfigure{mill}}[VideLayer{2}] \eTD \eTR \bTR \bTD \goto{\overlayfigure{hacker}}[VideLayer{3}] \eTD \bTD \goto{\overlayfigure{cow}}[VideLayer{4}] \eTD \eTR \eTABLE
