Thank you for your swift reply. Is it possible to get a cmake based
buildsystem integrated with CI and those quality services, if that is
the "final" build system for an essential or add-on module ?

You're going to have to volunteer to do the CI integration too.

Subject: [Development] Source incompatible proposal: removing Qt::WA_
values for widget orientation

Hi,
I'd like to propose a source-incompatible change for Qt 5: the removal
of Qt::WA_*Orientation.
The justification for this source-incompatible change is that (as far
as I'm aware) the API has never really worked anywhere except Symbian
(indeed, I only see code for S60 in the brief look I took now), even
Maemo5 took a slightly different route with QWidget orientation
(http://doc.qt.nokia.com/qt-maemo/maemo5-rotation.html) - and my
understanding is that QWidget is not the platform of choice for mobile
platforms now, so I don't expect this to work in the future either.
This not working universally has caused a lot of confusion in the
past, for the latest example that caused me to write this mail, refer
to: http://lists.meego.com/pipermail/meego-dev/2011-December/484371.html
The affected enum values are:
Qt::WA_LockPortraitOrientation
Qt::WA_LockLandscapeOrientation
Qt::WA_AutoOrientation
Comments?
BR,
Robin

And documented. :)
Can you please add to http://wiki.qt-project.org/Who_does_what the core
people responsible of Jira? (Gerrit, Mailman and any other web tool we
are using are welcome too).
If you feel busy or plain lazy you can simply reply here and I will add
the information to the page...

So...
When are we supposed to freeze? During Dev Days two weeks ago, we started
discussing about it being in January.
Can we set a more precise date? Let's say, a week [*]?
Also: what are the things we must still do before feature freeze?
[*] note: week numbers in 2012 will differ from the ISO reckoning and the US
one again, by 1.

What's state if the modules?
For WebKit I think an API feature freeze would be okay in January. I think
we are in good shape for that. Alexis, what do you think?
In terms of implementation WebKit is still a few months away from release
quality (think WebKit 2).

That's fine, I think the plan is to release around the beginning Summer, so
it
gives you a couple of more months.

Hi,
I would like to work on a 3D Audio module in Qt Playground [1] that might be
beneficial later for projects, like Qt3D, game engines, development
platforms,
or games without a platform underneath. Surprisingly enough, certain media
players also prefer using 3D audio and OpenAL in general for their goals.
The module name would be either QtOpenAL or 3D Audio. Either one works for
me.
The short description would be something like: "This module offers classes
that
make it easy to use OpenAL in Qt applications". It currently also deals with
convenient and more common tasks, like decoding from various compressed
formats
into raw PCM data. There are no license problems about using openal-soft
[2],
and one of main purposes is to be cross-platform, apart from Symbian at the
momment (tested on Harmattan as well). A lot of projects, including Qt based
game development projects, use "alure" currently which is a convenient
wrapper
around OpenAL, but not Qt based. Also, according to the author, it has some
design issues as well.
The project is currently hosted here:
https://projects.kde.org/projects/playground/multimedia/qtopenal
It is currently cmake based because I have more experience with that build
system, and I am happy with it. I also like the services provided by CDash
and CTest. I do not have any plans to change it in the near future. The
documentation is entirely missing, but will be amended as soon as possible.
Feedback is king! :) Thank you for your consideration!
Best Regards,
Laszlo Papp

Hi,
I hereby propose Alex Wilson for the role of approver.
His contributions to QtLocation (at the time still part of QtMobility)
started a bit more than a year ago and now that he joined us again he has
continued his contributions as part of Qt5. So far he has made contributions
to the Maps and Positioning API. I am certain though that there is much more
to come.
David Laing is seconding this proposal.

Hi,
Just confirming that I'm seconding the proposal. He's done and
continues to do work. His impact is even net-positive after the
confusion of having two Alexs in the same team is factored in :)
Cheers,
Dave
