        If you can't do Windows, it kind of throws out the whole crossplatform thing.

            Check out wxWidgets [wxwidgets.org] (formerly known as wxWindows) for an alternative. No, the support isn't as good as Qt, even if you pay. On the other hand, unlike GTK, your app won't look and run like ass on windows. And the community support via IRC and mailing list is excellent. wxWidgets is, in fact, the only toolkit I know of that is mature, cross-platform, and free.

        You really can't compare Qt with GTK because Qt is more like a development platform/framework than a just a GUI-library. WxWidgets [wxwidgets.org] is much closer to Qt than GTK will ever be (and it uses GTK for GUI-drawing on X11), but Wx is nowhere as mature as Qt at this point.

        I started to use Wx for an application I'm working on, but it was impossible to even get a decent looking TreeView/CList with checkboxes which resizes in a sane way. After much frustration with Wx I switched to plain GTK in which I could great a GUI the way I wanted to, but now instead I have to look for external libraries for everything like sound playback, database connectivity, networking support, regexps, and much much more. It's like hell to support on several platforms. :P

        If Qt-Free was avaiable on Windows I could stick to Qt-conventions and support the application on all platforms with just a simple recompile.

          I've been using wxWidgets for quite a while. I must admit that it took a little getting used to, but I don't think the parent post does wx justice. Sure wx isn't as mature as Qt, but it is Open Source (which /. ers should like), it can be used in commercial apps (which people that like selling software should like), and the guys working on it put in a ton of time making a great library. The differences between wx 2.4.2 and 2.5.2 are quite impressive, and their current MacOS guy seems to be making an effort to bring wxMac along by leaps and bounds.

          Resizing isn't as tough as you think, look into wxSizer objects. If you want a more robust basic tree control, take a look at wxTreeMultiCtrl [xs4all.nl], or sub-class wxTreeCtrl and make your own. It's the beauty of the system. I've used tree controls in several applications without such pains.

          It's always a bit of a trip learning a new GUI toolkit, but the sheer volume of great tools included in wxWidgets overshadows any pitfalls found right now.

          Just MHO.

    Qt has always been techically superior and rather geek-friendly. Looks like in the new release they have found PHB-friendly names for their existing components. For example, they call the QTL (Qt Template Library - their replacement for STL) "Tulip".

    Seems like they have changed more classes than they usually do, and have moved a whole set of "obsolete" classes into a separate compatibility library to help the transition from Qt3 to Qt4. This probably means that developers have a few years to remove these classes from their codebase before they go from "deprecated" to "completely removed".

    The press release seems to be quiet about their previous challenge to Java (they have claimed a few months ago to produce a Qt4 that will be in "direct competition" to Sun's offerings). I'm kind of happy about this.

    Secondly, under the GPL for non-commercial usage only

    However, QT for Windows is not released under the second license, meaning that if you want to develop with QT and the Windows platform - even if you are a non-commercial entity - you must purchase a commercial license (or manage to persuade the nice folk at TT to grant you a license, as a few open source projects have managed to do).

    Other technologies are trying to open up to more languages, but TrollTech has decided that C++ (their own version of C++) is all that anyone needs. Even as a C++ developer, I recognize that this is a bad strategy.

      GUIs are inherently object-oriented and amenable to dynamic programming techniques. That's why people like Objective-C (Cocoa), and Smalltalk so much for GUI programming. The STL style of C++ is very anti OOP and anti dynamic programming. Indeed, the creator of the STL, Alexander Stepanov, has said OOP is a hoax. [c2.com] While Stepanov is entitled to his opinion, and the STL is certainly useful for a wide range of tasks, it's silly to try to shoe-horn Qt into a programming style that doesn't fit it's problem domain.

  • Qt Non-commercial version for Windows (Score:4, Interesting)

    I've been reading a lot of posts to this article which claim that there is no free version of Qt for Windows. If so, then what's this [trolltech.com]?

    I don't program on Windows, so I can't tell definitively, but that web page reads right. It sounds like there's a GPL version for Windows that lets you write non-commercial software without paying a dime to Trolltech. It's based on version 2.3, but it is Qt.

    If I'm wrong here, please educate me.

    • Qt Non-commercial for Windows is based on ancient Qt 2.3.

      Qt Non-commercial for Windows requires Microsoft Visual Studio 6, which is priced out of my league. Most hobbyists on Windows would prefer something that works with MinGW, a port of GCC to Windows, and Dev-C++, an IDE around MinGW.

      Qt Non-commercial for Windows is not published as source code and is thus incompatible with libraries published under the GNU General Public License.

        Free is out of your price range? [microsoft.com]

        Everything else I do agree with however.

        • Visual C++ Toolkit 2003 is the command line compiler, roughly comparable to the MinGW 3.0 distribution; it's not the Studio (IDE). I guessed that Qt for Windows required some sort of IDE integration. Even if not, is Visual C++ 2003 compatible with libraries and project files from Visual Studio 6? There are two differences involved here: newer compiler (different flags) and lack of IDE (possible different project file format).

          • It's a commandline compiler, yes, but it's fully optimizing and all, it's the full blown compiler. It's so much faster than gcc it's not funny. I can hardly imagine it requires the graphical capabilities of the IDE, merely the workspace/project file format. I think you can be pretty sure the flags won't change -- it's converting MSVC5 projects that's cumbersome, since MSVC6 got rid of LIB.EXE for LINK.EXE (which *is* different). If you know someone with MSVC6, you can ask them to output makefiles from t
        • That's a link for the vc toolkit 2003. The Qt non-commercial Windows edition requires Visual Studio 6 and will not work with earlier or later compilers.

      There is a non-commercial 3.1.2 version, but it's only available with the new Qt book (forget the title). It's much better than the 2.3 NC version. Besides being newer, it also supports many more compilers (and even comes with an older BCC).

      Unfortunately, as you can see by those verions, it limits you to certain versions. How long after 4.0 is released until a NC version is available somewhere? For some people this is an insurmountable problem. For others, like me, it's merely an annoyance because Unix/Linux is my primary target platform.
    • While not completely free, a book written by two trolls is available here [trolltech.com] and sold through Amazon.com for $31.49. That book includes a non-commercial version of Qt 3.2 for Windows.
  • Gotta love the fact that this whole comment page is filled with plugs for WxWindows and arguments over licenses that I've heard 100 times. Qt is GPL, get over it, so is the linux kernel. You want a Qt backend for Windows, then visit sourceforge or pay up. I don't think anyone actually read the damn article and discuss the new features. The new paint engine, SVG and Unicode Text layout I'm really excited about. Not so much about the template stuff, although interesting.
