Description
As agreed in the last two meetings, we must comply with LGPL license conditions. This means that any group that is developing code that uses PyQt must have a commercial license before the code starts shipping. The cost is 450 Euro (+ VAT) as a one-off payment, for each seat. See https://www.riverbankcomputing.com/commercial/ for details.
GPhL has now bought a license; could the rest of you check whether you 1) never develop Qt-related code? 2) Already have a commercial Qt license? or 3) are going to buy one now?
The operative part of the Riverbank license FAQ is as follows - I gather we are not distributing PyQt, but having the users use their own copy:
Q. | Can my proprietary application be used with the copy of the GPL version of PyQt that the user already has installed (as part of their Linux distribution for example)?
A. | Yes, so long as you meet the following conditions:
- you are using the LGPL version of Qt
- your proprietary application has been developed with the commercial version of PyQt
- your commercial PyQt license covers the version of PyQt that the user has installed.
Q. | Can I distribute my own copy of the GPL version of PyQt with my proprietary application?
A. | Yes, so long as you meet the following conditions:
- the GPL version of PyQt is packaged and installed separately from your pr

oprietary application
- you meet all of the obligations of the GPL regarding your PyQt package
- you are using the LGPL version of Qt
- your proprietary application has been developed with the commercial version of PyQt
- your commercial PyQt license covers the version of PyQt that you are distributing.
