[PyQt] Question about the PyQt future (PyQt5)

[Detlev Offenbach]

Hello Phil,

thanks for the answers. Work is in progress to make eric5 and all it's plug-ins compatible with 
Python2. Once that is accomplished, support for eric4 would be dropped starting with the next 
stable eric5 release (whenever that will be after Py2 compatibility is reached). One future 
step in eric development could be to port it to PyQt5. Hence my interest in your plans. 
Meanwhile I got a few more questions.

1) Will PyQt5 and PyQt4 be API compaitble (i.e. exchangable) as long as only stuff that is 
covered by PyQt4 is used?
2) Will PyQt4 support Qt5 after the release of PyQt5 or will that be dropped?
3) What could be the benefit switch eric5 over to PyQt5?

Btw, did you realize, that it is now a bit over ten years you handed over the 'broken' eric 
debugger to me and pulled me into the business? It was on 24.11.2002, when the first alpha 
release of eric3, the first eric IDE, was announced.

Regards,
Detlev
