Today we have released the absolute latest version of Qt for all those cutting edge folks that want to try out the newest stuff – The Qt 4.7 Tech Preview.
The 4.7.0 TP is the first step of the 4.7 release cycle, and our goal is to showcase our newest technology (such as Qt Quick) and solicit feedback so that we may improve it before locking down our APIs down for the beta. Although the quality isn’t at production level quite yet, it should be good enough for demonstrating the new features we have in mind for 4.7 final. The final 4.7.0 release is scheduled for around mid 2010, pending feedback on the new features/designs, and the overall product quality.
For an overview of all our neat new features, then please check out:

To report bugs, and file suggestions, visit our bug tracker at:

This is a source only release, and thus, the zip file for Windows users, and .tar.gz file for all others can be found for compilation at:
http://qt.nokia.com/developer/qt-qtcreator-prerelease
My personal favourite feature of this release which I urge all of you to try out is the Qt Creator 2.0 Tech Preview which has full Qt Quick integration. With these tools you can create really neat stuff with big wow factor pretty quick 
Thank you all for your feedback so far, and please don’t hesitate letting us know what you think and what bugs you find!

Woohoo! I have been waiting so long for that post, the F5 key on my keyboard was getting worn.
@detro: It’s neither of those. The technology preview branched from 4.7 a short while ago to allow for a bit of testing and stabilizing.
@detro Indeed, Thorbjorn is right. It was branched at 1dca379031381eb7bff91970aec8056f1b7f2efb into a release branch where it was stabilized and only the more critical changes were cherry-picked into.
Any chance you could merge QtIOCompressor, QtLockedFile, and QtSingleApplication classes (part of Qt Solutions right now) into Qt 4.7?
Oooook. So, what should I do?
Working with master, first, and 4.7/4.7-stable now is a bit like “living on the edge”.
I wouldn’t mind some stability BUT I want to keep enjoying QML.
Should I use this release or stick with 4.7 from gitorious?
@detro we try to keep 4.7 stable as well obviously 
If you want the absolute cutting edge, that may break at times, then just stick with using the 4.7 branch. However, if it’s too much for you, then just fall back to the (a bit more stable) TP.
For Qt4.7 I want overall :
- QFlowLayout
- QtMessaging
- Qt3D
- QtContact
- QtMedia (not QtMultimedia)

Will mouse wheel events be available in QML?
Phones do not have mouse wheels…
@albert: but mouses have mouse wheels. And it’s bad if QML does not support this. See the “Bauhaus” visual designer which seems to use QML itself. You cannot scroll the element library using the mouse wheel. QML is not for phones only.
@TheBootroo and anyone interested:
There is already a Flow positioner in QML but I don’t know why it’s not still documented
You can run the following snippet on the QML Viewer
import Qt 4.7
Rectangle{
width: 320
height: 240
Flow {
width: parent.width
spacing: 3
Repeater{
model: 10
Rectangle { color: “blue”; width: 80; height: 60 }
}
}
}
QDeclarativeFlow
http://qt.gitorious.org/qt/qt/blobs/master/src/declarative/graphicsitems/qdeclarativepositioners_p.h
This brings a more general question, then: How well will QML be supported for non-phone applications?
Still trying to get a win32-msvc2008 build to work. And when is support for 2010 planned?
@Dom @Albert @Nils: QML does support mouse wheel. It’s all built on the top of the classic Mouse events. So, don’t worry
@Jesper: Indeed. 4.7 TP1 you released is enough for me and it’s stable enough. For the work I do I need to “show off” my doing: it would be HARD to justify a temporary 1-day break to management that barely understand what programming means
@diego.marcos thanks a lot but I don’t want to use QML
@TheBootroo: why not use QML?
Is there any new function for support REST in 4.7 ??
@albert: actually they do. Some phones have, in the middle of the keypad, an optical mousewheel. We support this (at least on Symbian)
Some times ago you had done nightly builds of Qt for Symbian/S60. How about qt 4.7 TP for symbian?
When are there going to be publicly available QT developed end user applications for s60v5 devices, instead of just the same demo pack? How about a QT based browser for s60v5
Hello,
I’ve filed a suggestion here http://bugreports.qt.nokia.com/browse/QTBUG-9606 .
This is basically asking for progress bar smooth animation in time for Qt 4.7/KDE 4.5.
And it has youtube videos and all too!
Was playing with KDE 4.4 code but realised you need it baked in to QProgressBar itself for best results.
Regards,
Vishal
Will the support for android be part of 4.7 ?
