GTG needs a GTK3 port

[Izidor Matušov]

This bugs was created by a splitting of bug #885320

GTG needs to be rewritten into PyGObject / GTK3 [1] Althoug it should be mainly about refractoring the code, it will be a big change for GTG.

Few links to documenation to port GTG:

The migration is needed, e.g. because Evolution library and current PyGTK doesn't play well anymore ( See bug #931539 )

[Lionel Dricot (ploum-deactivatedaccount)]

I don't consider it's critical. GTG is still usable as GTK2

[Vaibhav Mathur (silverspade-vaibhav)]

I really want to this. Can this be assinged to me?

[Joe R. Nassimian (nassimian-joseph)]

Vaibhav Matchur: I already started the port:
- finished the liblarch port to gtk3
- finished porting gtg's gobject, gtk, gdk, pango, and gdkpixbuf related code to pygobject's dynamic binding. (Gtk3 if you will).

checkout my branch and base your work on it. The process I used to port is documented here: https://live.gnome.org/gtg/GTK3Port

Liblarch can be found here:

I've pushed two patches in pygobject, that fixes some problems I faced when using the conversion script in pygobject, and adds 3 ways for programs to check pygobject's version.

import gi
gi.__version__ is a string containing a string representation of the version
gi.version_info is a tuple representing the version as (major, minor, micro)
gi.check_version() which takes either a string or a tuple and checks the version, and raises an exception when requested version is superior to available version, otherwise is returns None.

All this to say is that because of GtkTreePath's improvements in the git version of pygobject, I can avoid some of the hacks i used in the porting effort that aren't necessary anymore.

requesting version 3.3.5 which is the first version with my patches that came a little after the major fixes concerning tree related fixes in pygobject (namely gtktreemodel and gtktreepath).

I'm in vacation right now, and returning next monday to my normal routines, you can probably find me on irc as placidrage, most probably on the gimpnet server , the #python channel.

The big blocker for the port is the gnome-keyring part which is to be completely changed. I kind of have a solution for it back home, so take a shot at that, if nothing happens, find me on irc on monday and we'll take a shot at it together.

I planned a lot of other changes for gtg as well (not related to new features) but I've been busy fighting with pygobject related fixes and tests lately.

As far as I can tell the minimum dev version of pygobject required is 3.3.5, and according to this: http://packages.ubuntu.com/source/quantal/pygobject it is safe to consider that things will work correctly.

I'll soon (in less then a week) add the necessary information for developing with a working version of pygobject.

I began where Joe finished -- I merged his Gtk related changes with the current trunk and started a new dedicated branch for this bug: lp:~gtg-user/gtg/port-to-gtk3

It will be fun during next following days :D

[Parin Porecha (parinporecha)]

I had branched huxuan's branch to lp:~gtg-user/gtg/port-to-gtk3-py3

It has been merged in revision 1345.
There are still minor bugs, which will need to be fixed before releasing the port as 0.3.2

[Jeff Fortin Tam (kiddo)]

Thanks for your efforts on finishing that work Parin, much appreciated :)

Hi,

I'm maintaining gtg in Debian.

Is the migration was completed? Anybody knows if gtg-0.3.2 is comming?

Thanks
