Trolltech Releases Qt 4.0 413

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 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."

      Will the KDE library be available for windows now?

      Wrong question. Nothing legally prevents a native, GPL, KDE for Windows.

      The problem I bet is all the dependencies. I suspect someone will tackle native KDE/Win, but if so it will take a long time, because Windows coders won't get excited enough to help until it's far enough along development.

      It'll take a while for Qt apps to get built for native Windows (longer than it did for GTK apps like Ethereal to be ported to Win32 native)
    • AFAIK some people is interested in getting a native windows version of KDE (not the cygwin crap) out with KDE 4.0.

      I guess that has been one of the major reasons to extend the GPL licensing for the QT-windows-version. Really, there's a lack of decent freeware software in windows (advertising/spyware-free, etc), most of the decent software in windows is comercial.

      A windows version of all KDE apps means lots of people will use those apps, and unlike most of the 3rd party software, KDE software is (and fe
    • More importantly for me, will KDE itself be ported to win32 so I don't need to run cygwin beneath it!

      Whatever problems Linux has on the desktop, they are unrelated to KDE. I want to replace Explorer with KDE. Badly.

    Trolltech sounds so...dubious. I mean, when I think of Trolltech, I think of spyware. Hell, anything that is profession with the name "Troll" rubs me the wrong way.

    I can imagine their future... "The current stock value of Trolltech rose to 300 dollars a share..."
    • Spyware tends not to fly in GPL'd projects.

      Maybe people who get put in places of responsibility to make buying decisions have the capability to look at what they're actually selling, rather than going, "Eww! Their name has 'troll' in it!"

      They're from Norway, dude. Anything with 'Troll' in it is popular there. They even named one of their biggest oil-fields [] "Troll".

      So since Norwegians like trolls, obviously they don't call annoying people on the internet 'trolls'. They usually call them 'americans'.

      Personally I think of (obligatory dictionary quote): Troll \Troll\, n. [Icel. troll. Cf. Droll, Trull.] (Scand. Myth.) A supernatural being, often represented as of diminutive size, but sometimes as a giant, and fabled to inhabit caves, hills, and like places; a witch. This usage of the term "troll" predates the internet term "troll" by atleast 200 years, and is still the most common usage of the word in Scandinavia.

    I've worked with my fair share of windowing APIs and QT's OO approach to the problem is very well done. On the one extreme we have the heavy MFC which has grown out of control into a mammoth mess. wxwindows, pretty much a clone of MFC, shares the same issues as MFC. WTL seems hopeful, if only anyone was using it and it had any sort of support.

    The Win32 and Gnome APIs are written in C, so though they are fast, they doesn't get any of the programming benefits of Object Orientation.

    Thought it has a funny macro kludges in certain places, the QT API is absolutely a joy to work with.

      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.
    • Thought it has a funny macro kludges in certain places, the QT API is absolutely a joy to work with.

      Yes, it is a joy. I am compiling it right now, and I even left my BitTorrent client open for everyone else downloading it :-)

      They did make good on their promise to release it in the second quarter, which ends on Thursday. Still, I have a few GPL GUI applications I want to write for Windows, and it was worth the wait. Qt is much more pleasant to work with than GTK+ or Win32 API.

      I consider a huge ego a prerequisite to being cool. It's a warlord thing, so lesser beings might not understand.

      As for attempting world domination, that just comes along with the super powers. You get some free time, you get that old itch to conquer, and one thing leads to another.

  • would be a story about how KDE can be cross-compiled on linux to run on wine or natively on windows.

    at present, the only way to compile KDE for windows is by compiling it under windows (which requires that you have windows).

    and that means you have to utilise a specialised forked version of kde source code, which has a bastardised version of configure, called configure.bat.

    • I don't see what's vague about it. They are simply asserting that using the libraries directly (via. C++) and indirectly (via say PerlQT) still leaves you subject to the same license. The license makes QT GPLed. So if you distribute a PerlQT app internally you won't be able to assert copyright if an employee chooses to redistribute.

    From the /. summary:

    Trolltech has released Qt 4.0 both under commercial and GPL licenses [...]

    I think what was meant here was proprietary licenses, not commercial licenses. This is a rather common misunderstanding that stems from not seeing the GNU GPL as a license under which one may do commercial work []. But many developers and distributors have done commercial activity involving GPL-covered works over the years. What the GPL prohibits is distribution of proprietary derivatives, hence the GPL is not a proprietary software license.
