If the developers plan to use any of those features Jay mentioned then they
will need QT 4.3. That would become the minimum required version as soon as
one of those features was used, would it not? And Janne mentioned using
qtscript for theming. So it seems sensible to just make 4.3 the minimum now
rather than saying 4.2 now and then requiring 4.3 in 6 months time anyway.

Just to dive right in here....

This is a great time to do some housekeeping. QT4 port is a big change.
Personally I'd vote for the almost-released 4.4. The webkit argument is
good enough for me.

Stop whining that x distro only has QT 4.2 and therefore you should live
in the past. It's not that hard to upgrade Qt4. I'm sure repositories
for your distro will have qt4.4 builds available when it's released.
Amarok2 and other apps already require it for the webkit support, and
Myth should too IMO.

Certainly in Mandriva we have 4.3.1 in our stable release and we'll have
4.3.4 in the next version due out shortly. 4.3.4 has also been
officially backported to our stable release for those that want it and
when we switch to 4.4 in our devel os we'll do the same with that.

By the time .23 is out Qt 4.4 will be out and there will be repositories
available for it for all major distros.

Upgrading is not that much of a pain IMO and should not stifle development.

That's not insulting people. If I wanted to insult people I'd call them
whiners. This is just an observation.

Thanks for ignoring the whole point and the constructive part of my
response which was talking about the availability of pre-built binaries
for more recent versions of Qt and how this should not be a major
problem for anyone (at least not anyone tracking Myth development). Nice
take on my reply, I'm sure I could find a nice website link that has
some sort of rhetoric on that, if only I could be bothered to sink to
that level.

Personally, I agree with moving to Qt 4.4. I see little reason to
require Qt 4.3 over Qt 4.2. However, replacing MythWeb's kdelibs
dependency with webkit would be nice. I maintain MiniMyth and I would
love to get rid of the extra bloat created by including the MythWeb
required parts of kdelibs.

I know that upgrading to qt4.4 is not that difficult. I have regularly
rolled custom RPMs for different packages until my patches were accepted
upstream and found their way into the distributions RPMs. However, there
should be a compelling reason to make it a requirement.

What happened to 0.22?

Currently, Qt 4.3 is the minimum required version. Your example (which I
agree with), will be in Qt 4.4. Therefore, making Qt 4.3 the minimum
required version does not make the feature available.

I take that back. I see you've done this in a separate mail.

Sorry for whining :p

:p Time Travel. It's only available in Qt 4.5 previews tho' :p

Yeah, sorry if I wasn't clear. I think Qt4.4 (when released) should be
the minimum too.

the 4.4 is going to be released in about two months from now - probably
months or even years before the 0.22 stabilizes ;-)

Beeing a developer myself (not mythtv), I see it like as long as
MythTV is pre-1.0, it's considered pre-release software, and when you
use pre-release software, you should be prepared to upgrade some
dependencies along the way. If we were at 1.21 however, this kind of
upgrade should be held until a major release (ie. 2.0). If using Qt4.4
has valuable benefits over any previous versions, I say go for it.

For all those reading, that would be MythBrowser that has a KDE lib
dependency, not MythWeb. MythWeb has no dependencies on any KDE stuff
(I'm sure of this because I have no KDE stuff and I do have MythWeb--and
I don't have MythBrowser ;).

Thank you for the correction. I am not sure why I wrote MythWeb.

Mythweb has no kde requirements. Mythbrowser does.

Umm.. If Qt 4.4 hasn't been released yet then why make it a requirement?
Clearly the work being done on the port needs to be done with at most
4.3. Requiring pre-release software even for developers is generally
a bad idea. It significantly limits the breadth of testers who can
test the code for you because they might not have the ability (or
desire) to change the distro-provided Qt4. For example, my version
of Fedora provides Qt 4.3.3 but who knows when (or if!) they would
provide a 4.4 package. I'm certainly not going to try to build a 4.4
pre-release just to test Myth.

The compelling reason is much of the widget manipulation and customization
that I see MythTV requiring isn't available until Qt 4.3. Text layouts,
button views and theming. etc.

I have a couple of issues of Qt Quarterly on my desk discussing the *new*
amazing features of Qt 4.3 with regard to control over widgets and such. It
of course makes a casual reference that this stuff was available back in Qt
3 days so it's not really new... While it's been some time since I've plowed
through MythTV code. Some of the techniques discussed are items I know
MythTV relied on from the Qt 3 series.

Thank you for the explanation. That is the kind of thing I was trying to

Well a lot of this discussion is about QT4.3 vs QT4.2. I think the most
sensible thing to do is to just not concentrate on mythbrowser right now
and get everything else working on QT4.3, then, after the QT4.4 release,
switch over to it.

Getting a QT4.4 build for any distro is not that huge a hurdle for devs
IMO (but then I'm used to building packages).

Regardless, I think if the min requirement for 0.22 will be QT4.4 then
there is no point in saying that QT4.2 is the current min version. Just
my €0.02.
