[Sugar-devel] [DESIGN] Browse PDF handling

[Walter Bender]

2012/2/2 Manuel Quiñones <manuq at laptop.org>:
> I'm proposing, for the new and fresh Browse wearing WebKit, the
> following behaviour when clicking on a link to a PDF:
>
> - the PDF is shown in a new tab, next to the current
> - basic document navigation is provided to the user
> - as well, a button to save to Journal is provided
>
> Using the save to Journal button, the kid can now read the PDF
> starting the full-featured Read activity.
>
> This behaviour is similar to what Safari does, and I think it fits
> Sugar user interface better than other approaches we where thinking
> before, like start Read directly, which provokes an interruptive
> activity switch.  Also this way, an entry in the Journal is made only
> if the user ask for it, and allows a quick read of the PDF then you
> can decide on storing.
>
> If we go for this, some design decisions should be taken:
>
> - How can we provide basic PDF navigation?
>  1. Overload Browse buttons? This are: View zoom-in, zoom-out, Edit
> copy, paste, Go back page, go forward page buttons.
>  2. Add a special toolbar for PDF, add Save to Journal option in that toolbar

#2 seems to be the way to go.

>
> - Where to append Save to Journal button?
>  1. In the activity toolbar, like other activities have.  This
> matches well basic navigation 1 above.
>  2. In a special toolbar.  This matches basic navigation 2 above.
>
> For 1, I fear that may confuse users and may complicate code.  For 2,
> we can take Safari as reference.  It adds an overlay horizontally
> centered near the bottom of the screen [1].  We can do this with the
> new widget GtkOverlay [2].
>
> Am I overlooking something?  Comments?
>
> Credits go to Simon for the investigation :-)
