Trolltech Discontinue Non-Commercial Qt 101

Posted by timothy from the tradeoffs-and-obligations dept.
An anonymous reader submits "Trolltech has quietly discontinued their non-commercial version of Qt for Windows. This eliminates Qt as a choice for those wanting to develop free multi-platform software." Actually, according to the linked page, "if you write Free software (Open Source software covered by the GPL) you are welcome to download and use the Free Edition of Qt," and Trolltech points out that one can buy the current edition of Qt -- seems fair enough.

    In the free software world, QT is just a dependency for KDE (hence, only the free *nix version is important). Other libraries such as WxWindows are already more widely accepted by free software developers.

          Technically the wxWindows license is LGPL with exceptions. The exceptions make people like me happy (*), while still keeping the source under strict GPL.

          There is one significant problem that still affects wxWindows and that is that many Linux based PDAs use Qtopia which is based on QT and the QT license. This makes it difficult to do wxWindows for the Zaurus etc.

          • you hinted at one fault in wxWindows. There is no binding yet for KDE and gnome. I hope there will be some day. It would make wxWindows even better.
            • The binding on Linux is to GTK which is close enough to Gnome. They are currently working on the GTK2 binding which is mostly complete. I suspect that a runtime switch to GTK or KDE as appropriate would be WAY too hard to implement. Hopefully the freedesktop.org people together with the combined talents of the best GNOME and KDE hackers now at Novell will help make toolkits like wxWindows even easier, and always look normal to a user.

        • The lack of a Free Software Qt for Windows is a problem. But under X11, the dual QPL/GPL license grants *ALL* of the benefits of the LGPL.

          But that's for Free Software developers. For commercial proprietary developers, if they're going to bitch at paying for commercial Qt, then I'm going doubly bitch at paying for their stuff. Fair is fair.

    Qt/Free on Windows was decreasingly useful .. it was a crufty old binary-only Qt 2.3, which is quite aged when you consider that Qt is up to 3.2.x. Being pre-3.0 there were notable differences between it and more 'modern' Qt versions.

      Well, you can do free cross-platform QT development on any platform you want, as long as that platform runs X11 and has a POSIX-like interface (and what platform doesn't, nowadays?). Now that XFree86 is available for Windows (which is awesome, BTW) it should hardly be any trouble at all to develop QT/X11 applications for Windows as well. But if you want native QT/Mac or native QT/Windows, you still have to pay.

    Since there is no Free Edition of Qt for the Windows platform, is Trolltech making some kind of statement that Free software does not exist for Windows? I can think of an example off the top of my head of a GPL program which is available only on Win32: FileZilla [sourceforge.net].

    I'm not saying Trolltech is obligated to make a Qt Free edition for Windows, but perhaps they should word things a bit differently on their website, along the lines of "If you write Free software for X11/Mac..." It's just plain misleading, to my thinking, to state it the way they are.

    Methinks we'll be seeing a lot more of this in future, ie: release software for free, let it become established for a few years, then discontinue the "free version" so people are, to some extent, forced to buy the commercial version.

    Companies should either do free or commercial software, or both. They shouldn't establish their product as free and then start charging for it once people rely on it.

    Trolltech is saying that there is no free lunch. It gives the source out freely to Free Software users because they receive so much from Free Software and the Open Source model. They could build a viable business model with their free software alone.

    The reason why they refuse to give away their source code and add value to the Windows codebase is because they get nothing in return from them. In fact, they have to pay Microsoft for the "privilege".

    It's also much more difficult to code for the Windows platform than for the standard free software *NIX platforms.

    One of the reasons is the lack of reliable documentation. Sure, there are tons of documents out there on Windows, but there are too many contradictions in them. Which one is correct? Which calls may cause seg faults? Which ones will cause the entire system to fail? No one seems to know. Microsoft has a mysterious habit of presenting second-rank "experts" to the community, while hiding the first-rank and true experts from public view. This means when you go read an article written by an "expert" in the field, it is really a nice PR ploy with little or no true substance. I guess you have to pay a lot more or live on the Microsoft campus if you want access to the actual experts.

    The other is the short, abrupt upgrades that totally invalidate their previous work. Imagine rewriting the entire KDE codebase every year or so because Linux and XFree86 decide to move around all their APIs and invalidate previous ones. That is what Microsoft is forcing people to do. I've experienced it first-hand from about 1997-2000, as I was writing a game based on Direct3D. How many times did the API to Direct3D experience a complete rewrite? I don't recall, but I think it was something like 4. I also had to code up from '95, to '98, and then to 2000 and NT. That was a very painful experience for me. I feel the pain of the people who are chained to their desks and forced to code for windows. You really are slaves to the whims of Redmond.

    The other reason is that when they have a problem, they cannot "dig down" into the source code or the community to discover if the problem is on their end or the OS's end. When developing for Linux or *BSD, when you run into some serious problems, you can either look into the source code itself or even ask the kernel community if there is a bug there or what you are doing wrong. Such is not possible with Microsoft unless you shell out some cash and spend a lot of time speaking with phone monkeys.

    If you really, really need a Windows version of Qt, and if it really is going to save you a lot of time in your project, then you should gratefully shell out the money to get a developer's version of Qt for Windows. And you can't complain that it is not open source -- neither is Windows, and yet you use that. Your money is going to hire people who really don't want to code for Windows. You will be paying to have them trained on the latest versions of windows. Not just the APIs, but the new applications as well. Your money is going to be used to purchase the latest and "greatest" windows platform for them to code, test, and build on. Your money is going to go to the phone monkey department as they call in to see if there is a bug in the Windows OS or if they are just reading the wrong version of an "expert's" analysis. Your money is going to be spent lining Bill Gate's pockets, and hire a few people who would rather be coding for Linux, in other words.
