gnome-pdf-control

Hello,

I work with students on a card we plug in the parallel port that
regnonizes some words (for example :"next", "previous", "up",
"down",...). Our goal is to enable spastic people to read book on a
computer.

So, we would like to have entire control on the gnome-pdf-control from
this card : changing page, zoom in, zoom out and scrolling the window.

- Zoom in, Zoom out : gnome-pdf-control has a zoomable interface that
enables that. Good !
- Changing page : thanks to some developers on gnome-devel-list and
pygtk, we can do that now. :-)
- Scrolling the window : I don't know how to do it. I can't find the
right interface (wouldn't it be a good idea to add a method allowing
this in Bonobo_Zoomable ?). Gnome-pdf-control has not verbs to do that.

Should I make changes in my gpdf sources ?

Thanks in advance.

David.
