Summary
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
Owner
Current status
- Targeted release: 0.96
- Last updated: 31 Jan 2012
- Percentage of completion: 100%
Initial information
- This feature depends on evince 3.4 (shipped in F17)
- The bindings are already fixed and packaged in Fedora Rawhide
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 [1].
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
Have a working Read activity. Evince does not include the old bindings anymore.
Scope
What work do the developers have to accomplish to complete the feature in time for release? Is it a large change affecting many parts of the distribution or is it a very isolated change? What are those changes?
UI Design
Does the feature have a direct impact on the work flow, or does it need a UI? Link here mockups, or add detailed descriptions.
How To Test
Need be tested in a F17 based image
Dependencies
Evince 3.4
Release Notes
This change is a internal implementation issue. To the users should be almost equal than the previous version.
