The pygtk bindings used until F14 to use the evince backend in Read activity, are no longer present in F16.

We need use the new gi based bindings

* This feature depends on evince 3.4 (shipped in F17)

* The bindings are already fixed and packaged in Fedora Rawhide

=== Implementation plan ===

=== ~~Implementation plan~~ ===

The first step is port this simple demo to gtk3:

e = evince.View()

docmodel = evince.DocumentModel()

doc = evince.document_factory_get_document('file:///path/to/file/example.pdf')

docmodel.set_document(doc)

e.set_model(model)

With gtk 3 is:

from gi.repository import Gtk, Gio

from gi.repository import EvinceDocument

from gi.repository import EvinceView

class HelloWorldApp(Gtk.Application):

def __init__(self):

Gtk.Application.__init__(self, application_id="apps.test.helloevince",

flags=Gio.ApplicationFlags.FLAGS_NONE)

self.connect("activate", self.on_activate)

def on_activate(self, data=None):

window = Gtk.Window(type=Gtk.WindowType.TOPLEVEL)

window.set_title("Evince Gtk3 Python Example")

window.set_border_width(24)

scroll = Gtk.ScrolledWindow()

window.add(scroll)

EvinceDocument.init()

doc = EvinceDocument.Document.factory_get_document('file:///home/gonzalo/Desktop/AjedrezyLeyendas-Postmortem.pdf')

view = EvinceView.View()

model = EvinceView.DocumentModel()

model.set_document(doc)

view.set_model(model)

scroll.add(view)

window.show_all()

self.add_window(window)

if __name__ == "__main__":

app = HelloWorldApp()

app.run(None)

=== More information ===

Not directly related. Evince developers have a request to support epub format [https://bugzilla.gnome.org/show_bug.cgi?id=539347].

We are implementing our own epub reader displaying it with webkit. If implemented in evince, we can simplify our code a lot.

== Benefit to Sugar ==

''What is the benefit to the platform? If this is a major capability update, what has changed? If this is a new feature, what capabilities does it bring? Why will Sugar become a better platform or project because of this feature?''

~~''Make sure to note here as well if this feature has been requested by~~ a ~~specific deployment, or if it has emerged from a bug report~~.''

Have a working Read activity. Evince does not include the old bindings anymore.

== Scope ==

Line 36:

Line 88:

== How To Test ==

~~== User Experience ==~~

Need be tested in a F17 based image

~~''If this feature is noticeable by its target audience, how will their experiences change as~~ a ~~result? Describe what they will see or notice.''~~

== Dependencies ==

Evince 3.4

== ~~Contingency Plan~~ ==

== Release Notes ==

''If you cannot complete your feature by the final development freeze, what is the backup plan? This might be as simple as "None necessary, revert to previous release behaviour." Or it might not. If your feature is not completed in time, we want to assure others that other parts of Sugar will not be in jeopardy.''

~~== Documentation ==~~

''Is there upstream documentation on this feature, or notes you have written yourself? Has this topic been discussed in the mailing list or during a meeting? Link to that material here so other interested developers can get involved.''

~~== Release Notes ==~~

This change is a internal implementation issue. To the users should be almost equal than the previous version.

~~''The Sugar Release Notes inform end-users about what~~ is ~~new in~~ the ~~release. An Example is [[0.84/Notes]]. The release notes also help~~ users know how to deal with platform changes such as ABIs/APIs, configuration or data file formats, or upgrade concerns. If there are any such changes involved in this feature, indicate them here. You can also link to upstream documentation if it satisfies this need. This information forms the basis of the release notes edited by the release team and shipped with the ~~release~~.''
