[NTG-context] \fieldstack

[Wolfgang Schuster]

Hi,

fieldstack based animations result in a broken PDF document.

\setupinteraction[state=start]

\starttext

\definesymbol[one][\tt 1]
\definesymbol[two][\tt 2]

\definefieldstack[some][one,two]

\defineoverlay[some][\overlaybutton{Walk{some}}]

\framed[frame=off,background={foreground,some}]{\fieldstack[some]}

\stoptext

This is LuaTeX, Version beta-0.70.1-2011051908 (rev 4277)

[NTG-context] \fieldstack with mkiv

[Peter Münster]

Hello,

What is needed to get \fieldstack working in mkiv?

The following example works with mkii, but not with mkiv:

\setupinteraction[state=start]
\definesymbol[step1][AAA]
\definesymbol[step2][BBB]
\definefieldstack[test][step1, step2]
\starttext
\fieldstack[test]

Just click \goto{here}[JS(Walk_Field{test})] to walk through the fieldstack!
\goto{(restart)}[JS(Set_Field{test, 1})]
\stoptext

TIA for any hints!
Cheers, Peter

Re: [NTG-context] Weird Fieldstack problem

[Zhichu Chen]

Hi Aditya,

In my situation, I can't use buffer conveniently. So is there an easy way to
\includeMPgraphic recurrently? I've tried

\newcount\steps

 repeat the following block several times
\advance\steps\plusone
\startuseMPgraphics{step\the\steps}
. . . % Some random graphics
\stopuseMPgraphic
%

\startuseMPgraphic{aa}
\dorecurse{\the\steps}
 {\includeMPgraphic{step\recurselevel}}
\stopuseMPgraphic


but, it's not working.

Yes, \definesymbol[a][b] is roughly equal to \def\a{b}, for example

\starttext

\def\something{aa}

\definesymbol[aa][\something]
\symbol[aa]

\def\something{bb}
\symbol[aa]

\stoptext

This is what is also happening in your case. You need to go back to the
definebuffer and processbuffer as suggested in metafun manual.

I do not know if it makes sense to have a \edef version of
definesymbol. In any case, getting expansion to work with \getMPdrawing
is going to be difficult.

Re: [NTG-context] Weird Fieldstack problem

Hi Aditya,

Actually, they should have the same boundingbox, the first MPdrawing
environment draws a line from (0,0) to (2cm,2cm) and the sequence MPdrawing
environments just add two lines that are in the previous boundingbox.

I know what's happening now. \definesymbol doesn't define a symbol
from \getMPdrawing at once.

I haven't tested this, but I think that all elements in the fieldstack
should have the same bounding box. Look at the widget manual, where
Hans shows how to make sure that all elements have the same bounding
box.

[ Acrobat is required, but the trial version should work. Maybe also

[NTG-context] Any idea about copy or clone fieldstack?

[Zhichu Chen]

Hello everyone,
 
I want to display dynamic system time on each page of my presentation. Displaying system time can be manipulated by _javascript_ but, a field can be shown only once. So I used clone field and it works very well for me.

 
But when I want to change the font (xxx presents the variable that gets the field):

xxx.textFont = font.LucidaBright ;

it can be compiled successfully, but when I open it with acrobat reader, there are many errors from _javascript_ console. So I think that JS don't know the font, and I don't know how to embed the font into pdf file and make JS knows it.

 
Then I turned to use field stacks. I use MetaPost to draw some needles and use JS to set_Field the fieldstack to the correct frame. But when I want to display the second clock, it seems that I should write another JS code to control the other fieldstack.

 
So is there some command that clones the fieldstack just like \copyfield? Or how to assign the font of the field as I like?
 
Thank you.

Took some time, but it works now. What I don't understand, is the
strange behaviour of the offset parameter in this case. See attached file.

The one I pointed out doesn't have an obvious solution since (I think)
the reserveobjnum spacing change breaks with pdftex 1.30 but is needed
with pdftex 1.21.  I guess the magic line could be wrapped in a test
for pdftexminorversion or something like that (and that wrapped in a
test for using pdftex at all).

Thanks Sanjoy for pointing this out. Both problems are still *unfixed*
(beta from 17.04). Unfortunately fixing them doesn't solve my problem.
I'll try it again later. Maybe I was to tired yesterday to solve this
and the error is on my side...

> there are still some problems with spurious spaces.

Just on the off chance that it's the same problem I had with some section
numbers getting an extra space before them (in pdf mode):

If you are running pdf(e)tex 1.21, you might need the patch below;
then remake the formats.  I think (but haven't tried it myself) that
pdftex 1.30 wants the original spacings (i.e. don't apply the patch in
that case).  See

Bad news...
I just tested this and it works only as long as you don't stack the
button and the fieldstack.

The only solution I have found, is to seperate the interaction button
into a pdf layer. Things work as desired (you need a context version not
older than 2 month), but there are still some problems with spurious spaces.

Example is attached.

Mhh, looks like you are going new ways with making the fieldstack
interactive (maybe not intended?). Sorry, but I can't help you any
further in this direction.

Another possibility that I can think of is to add an invisible button
field (same dimensions) behind a normal fieldstack, that calls
JS(Walk_Field...). Should cause no conflicts with the readonly (non
interactive) fieldstack [but this is untested!]. You can simply check
this with a button beside the fieldstack and if this works ok, you can use

\nointerlineskip
\smashedvbox{YOUR WALKBUTTON FIELD}%
\placefigure[here]{none}{\fieldstack[fgolds3]}

to place it under your fieldstack.

Re: [NTG-context] Fieldstack Walk

[Michal Kvasnička]

Good afternoon.

Many thanks, this  solves the problem -- at least partially. The frames 
are `walking' now, but new problems appeared. I found that when I set 
`clickin=...', it is set it automatically to `clickout' as well, so one 
mouse click runs the JavaScript code twice. So I've set it this way:

\definefieldstack[fgolds2]
  [sgolds1,sgolds2a,sgolds2b,sgolds2c,sgolds2d,sgolds2]
  [frame=off,option=,clickout=JS(Walk_Field{fgolds3}),clickin=]

It's better, but I found that now frames are walking in a strange order. 
It is rather puzzling, since when it is invoked by \goto{...}[JS(...)], 
it works well. Moreover, it does different things at AdobeReader 7.x 
under Linux, and Acrobat 4.x under Windoze.

Can you help me to solve it?
Many thanks once more.
M.K.

I see  :)

Can you try the following:

\definefieldstack[fgolds3]
 [sgolds1,sgolds3a,sgolds3b,sgolds3c,sgolds3]
 [frame=off,option=,clickin=JS(Walk_Field{fgolds3})]

^^

option is "readonly" as default (see \dodofieldstack in core-fld.tex),
so there can be no interaction (if I'm not again completely wrong).

first define the symbols, then define the fieldstack.

[NTG-context] Fieldstack Walk

[Michal Kvasnička]

Good morning.

I use a fieldstack in my presentation. I'd like to go to the next frame 
when I click on the figure. I tried this:

\definefieldstack[fgolds3]
  [sgolds1,sgolds3a,sgolds3b,sgolds3c,sgolds3]
  [frame=off,clickin=JS(Walk_Field{fgolds3})]
\definesymbol[sgolds1][{\externalfigure[golds1]}]
\definesymbol[sgolds3a][{\externalfigure[golds3a]}]
\definesymbol[sgolds3b][{\externalfigure[golds3b]}]
\definesymbol[sgolds3c][{\externalfigure[golds3c]}]
\definesymbol[sgolds3][{\externalfigure[golds3]}]
\placefigure[here]{none}{\fieldstack[fgolds3]}

I thought that `clickin=JS(Walk_Field{fgolds3})' makes precisely what I 
need, but it does not. How can I make it work?

With many thanks yours
Michal Kvasnicka
