    Default Qt vs GTK licence question


    Hi,

    I have a few doubts about the Qt and GTK licences for commercial
    software. What I know is that with GTK you can do almost whatever you
    want, I mean you can develop your software, then sell it and it's up to
    you if you include the source code with the CD or DVD or the media you
    choose. On the other hand, with Qt you have to include source code if
    you are using it with the open source licence, but you don't have to if
    you paid for the commercial licence. Am I right with these points? or
    with GTK you always have to give away the source code?

    Thanks.

    As usual, it's always best to check with the official sites.

    Qt licensing:

    'Qt Licensing — Qt Software - Code Less. Create More. Deploy
    Everywhere.' (http://trolltech.com/products/appdev/licensing)

    Gtk+ licensing

    'GTK+ - About' (http://www.gtk.org/)

    in particular:

    >
    > GTK+ is licensed under the GNU LGPL 2.1 allowing development of both
    > free and proprietary software with GTK+ without any license fees or
    > royalties.


    Pretty straightforward I would say.

    Thank you, I get it now. Still it seems to me that if you use LGPLed
    tools it'd be not so nice to hide source code.

    I have never made any program under linux, yet have experience with
    c/c++ under windows so I'm checking what toolkit is better for me.

    I've been playing with both and GTK+ seems to be more simple yet
    powerful, but KDE 4 DE is awesome =) so I'll have to make my mind (which
    is tending to GTK)

    regards
