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...

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.
I downloaded the movie via BitTorrent, but it does not seem to work. Is this encoded in some funky format?
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.

While GTK+ is written in C, they have always used the object-oriented paradigm. There are, of course, wrappers which make both branches of GTK+ easier to use in whatever language you choose.

Haavard and Eirik Eng were thinking about what to call the company for a while. One night,Haavard had a dream where the company was called "Trolltech". In the dream his wife hated the name, so he asked her what she thought when he woke up. She liked it. The rest is history.
As to being referred to as "Trolls", we don't mind. Trolls are something very Scandinavian, and in a way provides a title for all of us to share. It's kind of a bonding thing.
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.
Do not click on the link in parent! This is a troll which makes your browser go nuts.
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!!
Well, you must have messed up your system. Have you enabled the keyboard layout switcher in KDE? I can type not just accented letters, but Greek, Russian and devanagari in KDE, and I've never seen a difference between distributions.
So: inputting accented characters does not have to be fixed, it has never been broken; you need to fix your system.

It is BSD licensed, it comes with IDE on both Linux and Win32, and it kicks ass for productivity.
See comparison with Qt.

For the click-alergic people:
Please note that the Open Source Edition of Qt will support the MinGW compiler. Visual Studio support and integration is provided with the commercial Editions of Qt.
They also provide a package that will install the binaries, and tries to install the right version of MinGW. A Torrent is:

WxWidgets doesn't have Developers Fees, and uses the Native GUI on Windows, GTK, Mac, and even embedded systems (There's that crossplatform you claim only Qt has)...and All with standard C++ (No stupid Metacompilers needed). WxWidgets used with MinGW or Cygwin make for the ultimate competition, without the Qtlib nonsense. And considering WxWidgets uses STANDARD C++, I'd say it is more portable than Qtlib. Finally, compared to WxWidgets, I'd say that, yes, $5000 per developer is expensive for its type of toolkit.
I don't mind you FUDsters promoting Qtlib or Trolltech, but at least be truthful about it.
And, for your information, here's the info about WxWidgets differences...this might help you keep your facts straight: http://wiki.wxwidgets.org/wiki.pl?WxWidgets_Compa
I like it.

Looks like a troll, but it seems it's better to clean up other people's misconceptions anyway.
No can do. GPL and BSD are incompatible according to our friendly psychos at FSF.
Only that archaic, ancient, malicious BSD with advertising clause.
The more modern variant is not, and it's 100% OK to use it in Qt programs, it's just that the recipient has to be able to distribute it under the GPL if he so wishes.
