Re: [evince] plugin: save document interaction

[Mike Marchywka via evince-list]

It seems to be mostly Gtk but the filenames AFAICT go with the document not 
view. 
It looks like the document interface has a get uri function but you would have 
to look.

EvDocument *document = view->document;


#include 
#include 
#include

thanks for your replies.

If I got you right, there are variables in   ev-view.c  that contain 1) 
filename 2) cursor position 3) "scroll information" ( btw, how is the scrolling 
implemented?)

what are the names of these variables?

One of the reasons I sent the mouse click positions as time stamped
datagrams was to develop a general set of plain "c" code to hack  around
interfaces for hacks like this. It is also a good base for remote
attachment. You might be able to work out a reasonable scheme to just
broadcast stuff and receive commands to invoke some methods-
I need to reload the pages for example- and then the control
logic can go anywhere. While maybe "void*" is not the most OO data type,
you can pass pointers and strings and whatever in any agreed upon way :)
Much of this stuff should be just calling existing functions and can be quite
separate although you need some hook to get the event info to send.

Evince doesn't have that kind of plugin so this would require code
changes to evince, possibly in EvWindow or EvView. Evince does have
backends for different document formats, which are loaded via a plugin
system, but the kind of plugin you are talking about is different.

[evince] plugin: save document interaction

[Stan Srednyak via evince-list]

Hello,

I would like to have a plugin for evince that upon a scroll of a document,
would save ( in a specified file) the time of the scroll event and the new
position of the scroll bar ( for the given document).

How do I write such a thing?
