Transition from pygth to python-gobject necessary in the long term

[PeterPall]

The next version of ubuntu will switch to gnome3.

Backintime-gnome is using pygtk. According to http://blog.rabbitvcs.org/archives/293 pygtk will never be ported to gnome3. http://www.pygtk.org/ does acknowledge that pygtk will no more be actively developed but does not tell about it being not supported at all in gnome3: "Existing authors of PyGTK applications are also recommended to port their applications to PyGObject to take advantage of new features appearing in GTK-3 and beyond.". Seems like they are right since on Ubuntu Oneiric backintime-gtk is still working under gnome3.

The successor of pygtk is http://live.gnome.org/PyGObject. The good news is that according to http://live.gnome.org/PyGObject/IntrospectionPorting (you have to scroll down a bit about to find any valid information on porting) porting seems to be doable, at least. The result of the first few porting steps can be found in the bazaar branch lp:~peterpall/backintime/gnome3/

Did try to convert the application.
Most of the gtk functions seem not ho have changed their name. But the gnome.* and vfs.* functions have. The latter seem to have moved to Gio. But I cannot find
 mime_type = gnomevfs.get_mime_type( gnomevfs.escape_path_string( path ) )
and
    gnome_props = { gnome.PARAM_APP_DATADIR : '/usr/share' }
    gnome.program_init( 'backintime', cfg.VERSION, properties = gnome_props )
anywhere.

Hi,
it looks like you never pushed your changes to your branch ~peterpall/backintime/gnome3. If you still have your changes could you please push it with 'bzr push ~peterpall/backintime/gnome3'?
BIT changed a lot since you've posted this but your changes still might be very helpful.

Thanks you very much.
Germar

We decide to drop Gtk+ GUI for a pure Qt4 GUI. This will come with next major version 1.1.0
