Trolltech have released Qt 4.4. This is a major release with many new features including WebKit, KDE's Phonon, Concurrency, Widgets on the Canvas and XQuery. This video covers what's new. Ars Technica has an in depth look while release dude Thiago has blogged with the now traditional developers' group photo.

Releasing on Qt 4.4 is a great news. This is a great toolkit and now it become ever better.
But what the hell?! Toolkit intended to work on all current major computer platform have released with a demo video, encoded in mov which require proprietary and unavailable for many platforms browser plugin and player. Really, the name of toolkit is not a reason to use video format of the same name.
It's the eternal disconnect between engineering and marketing. But at least Quicktime is more portable than Flash, the other common alternative.
Sorry but the .flv of the flash streams can be downloaded with some firefox extensions and viewer under VLC which is insanely portable. I'd rather have a flash applet than getting the unstable embedded video player to work btw. Embedded video players under linux sucks.
Please do not speak solely from your own experience when advocating decisions that affect many people. There isn't even such a thing as a functional Linux flash player. There's a binary plugin which happens to run on a few kinds of linux, and some open source attempts which barely run. MPEG4, DivX, some kinds of MOV, some kinds of AVI, Ogg Theora, a simple slideshow... all would be more portable.
I don't agree. I've tried Adobe flashplayer on several Linux distributions and it worked fine on every one of them. The only problem I've had was with a 64-bit install. Even with that I've got it working with a plugin (I believe it called nspluginwrapper in Debian) which makes 32-bit flashplayer work with 64-bit firefox.
And about a year ago I tried gnash and gave up on it because it wasn't stable enough. But I've recently tried the newest version and it's getting pretty decent; I'm using that now instead of flashplayer.
Okay, so you made it run on ONE architecture. Not even on an architecture that is really very similar to x86 -> x86_64
And you still call it portable? Please look up the word.
You're putting words in my mouth. The only thing I said was that there are 2 flash players to choose from in Linux.
Please do not speak solely from your own experience when advocating decisions that affect many people. An Ogg Theora video wouldn't play out of the box on Windows and OSX machines.

You only have to install a plugin:
http://www.illiminable.com/ogg/ (DirectShow/WMP)
http://xiph.org/quicktime/ (QuickTime)
so it isn't any harder to get to work than Flash on those broken OSes. And good OSes support Theora out of the box. :-)
A mov file won't play out of the box on Windows either..
Flash does not work under unapproved systems. That includes FreeBSD, OpenSolaris, and many others. I have not had good luck extracting .flv out of streams. But I've never had a problem with Quicktime on any platform.
I never watch Quicktime movies with a proprietary player. Install a codec pack and then watch a .mov file in any player you want.
Yes, that works OK for me.
HOWEVER, it only works on an x86 system!

Can't see the movie on my machine either. ALL codecs installed... Opensuse10.3 btw. Agree with VLC/Flashvideos, AVI and others. Even RealVideo would have been better since it is at least officially supported on Linux platforms.
Please everybody get your facts straight!
The video is h264+aac+mov. These formats are partly covered by patents, but they ARE documented. It is absolutely possible to play the video with free software (no extra binary codecs required), mplayer and xine should play it out-of-the-box.
While I would have preffered an entirely free codec-combination like ogg, this is way better than flash, real media or windows media. Even the download link is provided...
Btw. kmplayer plays the video fine inside konqueror, if your browser doesnt play embedded video, well...
With all the video formats on the web, the problem is not the "video format" part (even though it is a strange twist of fate that FOSS people would ask for flash+flv over h264+aac+mov), it is the "on the web" part.
I have yet to see an embeded player (Free or proprietary, any platform) that's really nice to use and works all the time, whereas some desktop players are really good (and most will play any file you throw at them).
Conclusion ? Please please please allways provide a download link for the video. For sites like Youtube it's a business decision not to provide one, but for promotional material like this it doesn't make any sense. If the embeded player works fine for some people, that's cool. For all the others (technical problems, slow connection, repeated views, file sharing...), all we need is a download link and we'll be happy.
You did realise that there is a download link on the bottom of the page?
;)
Like I said, I use kmplayer embedded in konqueror. I have no w32codecs installed and I've never encountered a video that doesnt play with the free software codecs mplayer has.
Then again, I did build mplayer with support for "patented-but-free" codecs.
dmiceman,
offtopic question: are you the fusecram/fuseiso guy?
I'm thrilled by the release!!!
Do anyboy know how much the Qt codebase grew after adding all the stuff it's been added since Qt 4.3?? Did it double??
Wonderful, Trolltech's unstoppable ;-) They're very inspiring to me!
i had to use windoze to view this video and why do i see a mac pc and not linux??
Because Henrik (the author of the video) uses Mac as his main platform. Really, Qt is a cross-platform toolkit, he could have shown the demos in any platform.
Have you seen the video on the demos on Embedded Linux and Windows CE?
so... any youtube link?
you can see it on linux with firefox/mplayerplug-in/mplayer
I think it depends on the Linux distribution. I have all those components on my Debian Lenny install and it doesn't work.
mplayer plus some codec packages (maybe not all 100% Free though) can play almost any format, including the format used for this video - I watched it. Don't waste your time with the crappy mplayer GUI though :)
Dude, you just said "windoze" you are so cool

To summarize: "3rd party" includes Webkit which is a large piece of code.
Phonon is also in 3rdparty, so those added files are not all WebKit.
Phonon is a drop in the bucket compared to WebKit (as far as LOC), let's be honest. :)
For those chasing KDE SVN, 4.4.0 is in qt-copy since last night. :)
...is that Qt 4.4 draws things _faster_ than Qt 4.3.4!
I recently ported Gambas GUI component to Qt 4.3.4. On my Core Duo with Linux (Mandriva 2008.1) and a NVIDIA 8300 GS graphic card, the Gambas IDE is almost unusable. Drawing and resizing are as slow as GTK+!
Then I downloaded Qt 4.4 RC1, and compare the demos and examples: at first glance, drawing is now twice faster, maybe faster than Qt 3. But using OpenGL for drawing does not work at all.
Of course, these are completely subjective tests.
But now I am happy, I will be able to finally use Qt 4 with Gambas! :-)
I believe that Qt slowness is derived partially from your nvidia card. People with certain Intel cards did not seem to have problems in Qt 4.3 ...
so basically it means that Qt 4.4 is fast in spite of Nvidia?
My guess is that credit goes to "Alien": now Qt applications appear to X as one big widget, so like resizing operations especially should be faster.

Interesting, if this really happens, then we will have Qt browser with Gecko engine! I still prefer KHTML though, but some sites really force me to use Firefox.
hehe, i was about to post the same link, it is a great news, and it looks like Nokia is pushing it, so with a real browser with qt, now kde is complete ;)as far as i love and use konqueror, i want just a browser not a super browser+file manager+ file viewers.
thanks mozilla and nokia
This is really good news: :-)
"Overall, though, what's on the Qt branch now works pretty well under X11;"
"I hope that in the future that the Qt port will be a toplevel supported Gecko port, alongside gtk2, Win32, and OSX"
I can't wait to try and build it!
:)
Excellent! Good job, Trolltech, we are with you!
Maybe this is slightly off topic but does anybody know when I might expect to see the option to use mac dashboard applets in plasma. I saw it in a blog entry a couple months ago and have been waiting for it since. If I remember correctly, using them relied on some changes in Qt that weren't in qt-copy. Now that the final Qt 4.4 has been released, is that possible?
It's possible now, and will be in KDE 4.1 ;-)
It's on digg now: http://digg.com/programming/Qt_4_4_Framework_Broadens_Rich_Application_D...
