Qt 3.3 Released; OSNews Talks With TrollTech's CEO 28

Posted by timothy from the little-trolly-footprints dept.
JigSaw writes "The new version of Qt (to be released Wednesday) features .NET support, full 64-bit support, IPv6 and backend support for two more databases. In light of the release, OSNews features an article with TrollTech's CEO, Haavard Nord. Nord says that he sees Linux strengthen its position in both business computing and embedded systems, while he forsees Qtopia and Linux taking over PDAs and Smartphones in the next few years." It's Wednesday, and Qt 3.3 has been officially released -- read on below for some more info.

Cronopios writes "The Norwegian company TrollTech has just released version 3.3 of their excellent cross-platform Qt toolkit, which is the foundation of KDE. This version adds support for .NET framework, 64-bit processing, IPv6 and gcc on MS Windows. The announcement and the complete list of new features and improvements are available at their website. As usual, the Qt libraries are released under several licenses, including the GNU GPL :-)"

    The main problem is that as a C++ developer on Windows, I cannot do /any/ development with Qt without paying a $2000 license fee. The only way to get a GPL version on the Windows platform is to purchase a $50 book that comes with a "limited edition" of Qt/Windows, but lord knows what that means. I wish they had a development version of Qt/Windows that didn't include any deployment licenses...

      Actually, you of course could use the X11 version in combination with Cygwin or Services for Unix and any X Server for windows. The X11 version of QT is QPL, GPL and commericial, but it is not restricted to Linux due to the cross platform nature of X11.
    • That WAS how it went in the beginning. The reason they removed the free Windows version is becuase too many people used it to write commercial, non GPL software, which goes against the license agreement.

      Having received that $39 book this week, let me offer a quick review of the enclosed Qt for Windows.

      The Non-Commercial Qt 3.2.1 for Windows is fully functional. You don't get source code, but you do get binary libraries for VC 6 and .NET, and Borland 5 and 6. Included is the Borland 5 compiler. Compare this to the earler noncommercial 2.3 version which only supported VC6. The library is a DLL, so you can't statically link. I don't think this should be much of a problem for most people, though.

      Functionally, it is identical to the Free Qt. Nothing has been removed. OpenGL, XML, tables, etc. Everything you're used to with the X11 Qt is there. The database component only supports SQL-Lite (included), and not OBDC or MySQL. Not being a database developer, I don't know how much of a problem this is. One might be able to create db plugins with the x11-free source code.

      Licensing-wise, it's the standard noncommercial license. Your resulting applications must be freely redistributable and source code available. And they have to be strictly non-commercial. Any Open Source license is satisfactory, though you might need to add an exception if you use the GPL. The DLL is freely redistributable WITH your open source application. The license does stipulate that your app must not be a mere wrapper around Qt, so as to export its functionality.

      This version does stick a "[Non-Commercial]" string in front of your title caption. This is the only functional change from the GPL/QPL version that I could find anywhere.

      The upshot: If you intend to write noncommercial Open Source software for Windows, this version of Qt is far from onerous. If your purpose is to provide Windows versions of your X11 or Mac Qt software, this will more than meet your needs.
    • I was wondering how u all consider using together Qt and quicktime api for video capture and as a basis for developing video editing tools. Did anyone started writing some capture, playback, image processing QT widget based on quicktime ? If some sample code could be published just as a starting point (the quicktime api in itself is well documeted but attached to win32 api on windows) , i am sure that would help many people frustrated by the lack of video i/o object oriented API. Thanks for any replies...

  • SuSE to use Qt3.3 with their KDE 3.2? (Score:4, Informative)

    I've noticed the following passage in their readme [kde.org] for the SuSE KDE 3.2 build:
    "Known issues:
    * Qt 3.3.0 final has not been released yet, we expect it next week
    and it will be avaible on ftp.suse.com.
    The qt packages in these directories contain a late snapshot
    (Qt 3.2 would need many patches, so we decided to go the 3.3 way)"

    As far as I can tell then expect a rebuild of KDE 3.2 now that the final of QT 3.3 is available... so SuSE users who've just upgraded to that KDE 3.2 you should have read the readme first if you have problems later when stuff built with the real Qt3.3 gets released... :)

    • In the readme [trolltech.com] of Qt-3.3.0b1, it says:
      The Qt version 3.3 series is binary compatible with the 3.2.x series - applications compiled for 3.2 will continue to run with 3.3.
      So I guess that means no rebuild after final Qt-3.3.0 is available because of the source and binary compability.

    I keep hoping that they will create PHP bindings for QT. They have been created for Python, they have been created for Perl, when is PHP's turn?

    Maybe with the new object model in Zend Engine 2, PHP5 will be deemed worthy.

  • When I tried QT for Windows last time, perhaps a year ago, it did not appear use the look and feel of the Windows platform, despite the company implying that QT adjusts to the native platform. If they would use actual native widgets, then not only would the user interface automatically change as the Windows controls are updated, but it would also at all times feel like a true Windows GUI -- because that is exactly would it would be! It's possible that QT's architecture is not well suited to mapping the cont
  • At several times in my career I would have simply gone with Qt but for the price and my unwillingness to be forced into releasing my code for free (freedomn is important even for developers). I mailed them and they won't even allow you to develop with the free edition and deploy with the commercial edition. Good luck to Troltech, their bottom line probably matters most.
    • I mailed them and they won't even allow you to develop with the free edition and deploy with the commercial edition

      That's because you could buy one commercial license and have your other 1,000 programmers using the free edition.

      As I understand it, the reason that the windows version of Qt has different licensing from the other versions is that many people were using the free version for their internal development (which the majority of software development is), so they were theoretically GPL, but neve
    • So basically your frusrations come from having to abide by the terms of the GPL. If you don't like it, buy QT and you can develop all the commercial apps you want. Or you could just use any of the dozens of other completely free GUI toolkits that are available, such as wxWindows or GTK+.

      And wow, I never would have guessed that a company would be concerned about making money. Who'd have thunk it? What would you have them do? Pay for their software development with t-shirt sales? Whatever.
      • " So basically your frusrations come from having to abide by the terms of the GPL. "
        Well not quite. The last time I looked and it might have changed is that you can not do any development under Windows using QT for Windows. I looked at there downloads so I am sure no GPL development using the latest version of QT for Windows.
        Also using GPL software for internal development and use is not a violation of the GPL. You have to give the souce away if you distribute it. Most people would not count internal develo
