Trolltech Releases Qt 4.0
lypanov writes "Trolltech has released Qt 4.0 both under commercial and GPL licenses for X11, Mac OS X and MS Windows. It is the first time that a MS Windows GPL edition is available. To celebrate the release Trolltech employees have created a song and a music video (Bittorrent download, Ogg Theora version). Read the Qt 4 Overview and the online Qt Reference Documentation for more information. You can download Qt from ftp.trolltech.com or from one of its mirrors. Work on KDE 4 has already started with making a development branch of KDE compile and run with Qt 4."
Has been for a while.

I think I need a new sig here.
. . . Object Orientation.
Is that kind of like Freshman Orientation? Show the objects around, get them used to the system, play volleyball with them, take them out behind the intramural fields and leave them to find their own way back...
SIGSEGV caught, terminating
wait... not that kind of sig.
1) QT doesn't suck
2) QT is GPL'd, not LGPL'd, so whoever wishes to use it in closed-source software must buy a license to do so. This means TrolTech can afford to continue developing it full time, while still getting it well-used in open-source projects.
3) The commercial license is very affordable.
4) QT is very cross-platform.
5) QT is very full featured, but still fast and light.
6) QT includes a very nice GUI designer.
Trolltech does have income. There are many businesses that won't touch the GPL with a 10 foot pole.
There are also Qtopia Pda and Phone Editions.

The company I work for has over a dozen enterprise-level licenses. We do it solely for the support. For us, it's essentially the same as using GPL code and contracting a 3rd company for fulltime support. Also, if Trolltech ever bit the dust, we've got the source code.

"Oh, uhm... would not time be better spent at kde.org fixing the many bugs in KDE 3?"
What makes you think they won't? Migrating to a new version of the Qt framework doesn't require rewriting all of the underlying logic, therefore allowing for bug fixes in a major portion of application code. Not to mention, there are plans for another release in the 3.x series (development can happen in parallel). Also, you should be happy to know that the things you complain about, kicker and kdesktop, are slated to undergo a major overhaul for the KDE4 release.
You have to use Mingw for the GPL'd version. The paid version supports Visual Studio, though.
what is the difference between mingw and a cygwin installed gcc/g++ environment ?
MingW is a native windows app that doesn't require the cygwin dll and creates exes that are standalone in windows.
I was quoted out of context in my autobiography...
I struggled with this a bit earlier today. The docs are pretty weak right now.
First, get and install mingw from http://www.mingw.org/download.shtml
Second, from Trolltech, get and install "qt-win-opensource-desktop-4.0.0-mingw.exe", NOT "qt-win-opensource-desktop-4.0.0.zip".
Then, from the Start menu, run "Qt 4.0.0 Command Prompt" to get a DOS box with everything set up properly. Then play with the examples and demos, using qmake to create the makefiles.
Hope that helps!!
