We had a GTK+ BOF today (2004-06-29) at GUADEC. I don't have
complete list of people there. There were about 30-40 people
total, with a good set of frequent contributors
(Tor, Matthias, Soeren, Anders, Jonathan, Manish, and others
that I'm forgetting)

The first topic of discussion was GTK+-2.6; trying to finalize
a rough feature set.

Some of the possible features discussed were:

Command line parser; Anders seems to have this pretty close
to completion. The big remaining question is how we do the
gnome_init() function of integrating command line arguments
from various libraries into the parsing.

The consensus we came to was perhaps a surprising one;
libraries shouldn't have command line arguments, except perhaps
one or two exceptions like --display.

Regular expressions; Matthias's stuff based on PCRE still
isn't quite ready to go in. It needs some actual use, and
it also needs to be modified to integrate with the Glib
UTF-8 functions in a more comprehensive way; it can't, for
instance, handle case-insensitivity beyond ASCII. The
current idea is to land it in libegg for now.

Icon list. The main open question here is whether to use
GtkTreeModel as the backend. Jonathan and Anders got together
after the meeting to take a look at this and decided that
it was not entirely trivial, but feasible. Anders took
an action at the meeting to write up the API and status
of EggIconList and send it to gtk-devel-list.

Rotated text and labels should be simple if Owen finishes
up a few more things for Pango-1.6.

Matthias took an action to look again at his GtkAbout dialog
work with the goals of a) keeping it very simple; if
you want any more you can write it yourself b) forgetting
about the single function call g_object_new() construction
and just having some setters.

Various picker buttons / entries were discussed:

File/Directory picker. There was some considerably discussion
of whether such a beast was an actually a good idea; it seems
that at least *some* apps do genuinely need file and
directory selection, and we're better off providing a widget
to do it well than have everybody do it themselves badly.
James Cape was nominated in absentia to write up his work
as a proposal and send it to gtk-devel-list

Date/Time. Seems useful, not clear if we have a close
enough prototype to get something in for 2.6. During
this discussion the ancient "Time API to go with date API"
bug (http://bugzilla.gnome.org/show_bug.cgi?id=50076) came
up. Apparently JP Rosevear has strong feeling about some
capabilities in this area that should be in GLib, so
he was encouraged in absentia to write this up for
gtk-devel-list.

The next two topics were

GTK+-2.8 plans. Didn't really have any time to discuss
this. See http://people.redhat.com/otaylor/guadec5/ for
discussion of Cairo plans.

How to deal with the big accumulating pile of bugs.
The idea of releases targeted at particular areas
(resolve/wontfix *all* GtkNotebook related bugs) came up again.
Should this targeting be for a stable release or an unstable
release? There's a good argument for doing it for unstable
releases ... some of the bugs are going to be API bugs.
But you'd want to apply relevant patches to the stable branch
at the same time.

And as a corollary to the last, the question of when
the first unstable release of GTK+-2.5 should be made
came up. "Almost immediately" was the thought.

Regards,
Owen
