goto with external document

goto with external document

[Matthew Baker]

Hi,

I'm trying to make a PDF file (actually a collection of linked PDF files)
idiot-proof.  I have a top-level PDF file with links to others.  When you
click on the others, they close themselves (\goto{....}[CloseDocument]).
The trouble is, if the user doesn't have Acrobat set up to open links in
separate windows, the top level document disappears because it's already
been replaced by the other document.  Anyway around this?  Can you make a
\goto go to the previous view if it is the only open window and close the
document otherwise?  Or something similar?  I can't provide two buttons
because the linked-to document only contains one thing: an image.

Of course, the user can click on the back arrow instead of clicking on the
document but that requires a bit of brain and I can't guarrantee the users
would have that unfortunately.

- Matthew

I fear this isn't possible. But how about only adding a \goto[PreviousJump]?
I haven't tested it, but this should always work. If a seperate window is open,
well then you end up with several open windows (if you don't use
\goto[ExitViewer] in the main document ;-) but I think this is best.

It might also be possible to set this value, but I don't know how.

Well you can assume they have more brain than you think -- in finding settings
which prevent your program/document from working ;-)

In spec-fdf.tex search for: 

             {\uppercasestring R /F (#4.pdf)\to\PDFfile}}% /GotoR

and change it into 

             {/NewWindow true \upper.....}}%

maybe that works (untested). If so, I can add it as an option.

My new line looks like:

{/NewWindow true \uppercasestring R /F (#4.pdf)\to\PDFfile}}% /GotoR

Is that right?  I get the text

  /NewWindow true 

in my document and Acrobat complains about not having the required plugin.

Ah yes, I see. Now tested it myself. 

First add: 

  \newif\ifgotonewwindow \gotonewwindowtrue % false by default, will be
key/value

Then change two times in spec-fdf.tex

  {\uppercasestring R /F (#4.pdf)\to\PDFfile % /Goto+\PDFfile=/GotoR ...
   \ifgotonewwindow\edef\PDFfile{\PDFfile\space/NewWindow true}\fi}}

so, the command is appended only when the bool is true.

Ah.  Works beautifully.  Can you make this an option?  Or, can I replace
it with something in my source file so that it doesn't happen by default?
