Qt "The PySide project provides LGPL-licensed Python bindings for the Qt cross-platform application and UI framework. PySide Qt bindings allow both free open source and proprietary software development and ultimately aim to support all of the platforms as Qt itself." Previously, the PyQt bindings were not licensed LGPL. If one wished to make a commercial application, then one previously had to purchase a commercial license for PyQt. Now it is possible to dynamically link to the LGPL-licensed PySide bindings instead. The PySide bindings are API compatible with PyQt.

"It's sad that Nokia hasn't found an agreement with Riverbank.


Previously if Riverbank's policy or FAQ or something stated that you were not allowed to use a commercial license for something that was developed using the GPL version. This was a restriction on the commercial license.
"

The restrictions were exactly the same as for buying Qt commercial licences at that time: something which actually has nothing to do with either of the licences (despite uninformed whining from various people) and everything to do with the policy of selling commercial licences in the first place.

Now there is nothing saying that I can't develop my closed source application in house using the GPL PyQT and switch to PySide when both my app and PySide are stable. If I made no distributions during development I don't need to release any source.


Some victory for Free Software that is.

With this particular project, Nokia has shown that its way of managing relationships with its corporate partners comes straight out of Microsoft's playbook. Still, it's yet one more area where Nokia gets to show off its complete lack of originality.

You weren't in the room when they were talking to riverbank and neither was I. They tried to work out a deal and couldn't agree on terms.

This doesn't seem like Microsoft at all. They tried to work out a deal, couldn't, and implemented it themselves from scratch, and released it as LGPL. In the end it is giving back to the community. If Nokia saw a benefit of releasing Qt under LGPL rather than GPL they certainly have that same benefit with any kind of bindings. Riverbank would never answer the question of whether it would change their license or not. Nokia didn't do this in the dark pretending that PyQt didn't exist.

It seems they are not starting completely from scratch; they are using boost::python and some binding generation stuff they used for Jambi.
