    Qt 4 for a GUI?

    Wondering if anyone here is using it. Is it good? Any major restrictions?

    Thanks.

    Thumbs up

    QT is the best!
    Personally I would go with GTK-- cause it's free.
    What do you mean restrictions? you still cannot divide by zero

    Ha!

    Well, by restrictions I meant things like, "it works great on Windows but doesn't on a Mac", or, "if I distribute an application, will it cause the user to have to install some runtime" type stuff.

    General info that a QT4 wannabe might want to know before he lays out some cash.

    In fact, you can have QT for free if you are developing open source software (or doing some non-proprietary thing, i don't know much about licenses but i think you can find a version of QT released under the GNU GPL license, just go on the official site and you'll find).

    And as far as i know, QT has been ported to a lots of platforms. If you are writing your application with QT, you are indeed writing portable apps and you'll only have to recompile your source code if you want it to be run under some platform. I think.

    But i don't know much since i never really used it... didn't have the time too...

    Anyway, I suggest you read more on it over the internet or try to find a book about it.

    I did pick up a book just Friday night. "C++ GUI Programming with Qt 4" by Blanchette and Summerfield.

    Trolltech indeed does have an open source version, and they are pretty emphatic about not using it if the application will be commercial. I can't tell what the commercial licensing costs, but I've been in the software business long enough to know that if they don't publish the price on their web site, it ain't going to be cheap.

    I will most likely download the open source version at some point to get familiar with it and test out some sample apps. But for now, I've too many other irons in the fire.

    True, QT has a dual license. one for open source and one for closed source.
    The only thing I don't like about QT is it price. I don't remember exactly but I think it is around 3000$ +- 1000. which I think is alot for a small business.
    Especially since there is a good alternative - GTK.

    The open-source version is under the GPL. Part of the free nature of this license is that Trolltech has no say about what you use the application for. You can use it for a commercial application - just remember that your application will have to be under the GPL, too, which means, among other things, that anyone buying your app has the right to redistribute it.
