[PyQt] PyQt4 Support for Multiple APIs

[Detlev Offenbach]

Hi,

eric is using the new APIs (i.e. sip.setapi(…, 2) in order to allow it to be executed with Python2 and Python3 using PyQt4 and PyQt5. Dropping PyQt4 support for the new API would be a slight disaster for me. Hope I read the post correctly.

It was never intended that production code should make use of it - although I doubt I ever made that as explicit as I should have. For example, all the packages used by an application must agree to use the same APIs, which makes using third-party code problematic.
