Hi,

Nop, that's not true. The only requirement imposed by PyQt to open source projects depending on it is that their licenses be compatible with the GPL. This is clearly mentioned in the PyQt wiki:

Cheers,
Carlos

Have you considered the licensing implications? PyQt is GPL, and actually *depending* on it (instead of using it as one of two possible options) would require Spyder itself to be released as GPL, wouldn't it?

    Hi all,

    Since today, we officially stopped to support PySide in the Spyder
    master branch (i.e. in the future Spyder 3.0, Spyder 2.3 still
    works fine with it though). This means that:

    1. If PySide is found in your system, and PyQt5 nor PyQt4 are
    installed, Spyder will try to use it. But at the moment, our
    master branch has several crashes with PySide that we don't plan
    to solve (at least not me, other core developers have shown
    interest in doing that but nothing has happened so far :-).
    2. We're not going to solve more bugs related to PySide in the
    future (again, at least not me :-)
    3. Support for it will have to come from the community.

    The reasons for taking this decision are explained in the link
    referenced by Anatoly, in case someone wants to know them. Nobody
    is getting paid to support only PyQt (4 or 5). It was just a
    pragmatic decision based on the amount of time the development
    team has to support several Python Qt bindings. Given that we're
    now supporting PyQt5 (and that PyQt5 is going to be our default
    choice for Spyder 3.0), we don't have time to support both PyQt4
    and PySide. And because of the uncertainty of PySide's future, we
    decided to not support it anymore.


    Cheers,
    Carlos

    Hey guys, where is the discussion about that?
    I am just curios - does anybody is getting paid
    to make Spyder work only with PyQt4?

    Yes. PySide needs more companies interested
    in this binding to support this initiative, but the
    project is far from being dead.
