[PyQt] Version matching: Qt and PyQt

[James Polk]

Thanks for you responses,...

lol,.yes, I am aware that Maya requires a certain version combination...
My apologies for not being clearer...I was thinking of version relationsship
between Qt and PtQt.
> In practise, you determine the lowest Qt version that you need to support
yes,...this is precisely why I was wondering if there was a version table,etc..

Putting Maya aside for a moment, and speaking only in terms of Qt and Py terms..


Phil,...you seem to suggest that for OSX Lion, I can grab the latest version of Qt
(or the version that Lion needs) and then grab the latest version of sip/PyQt ?
(in a Python 2.6 world)


Thank you guys very much for responding,
Cheers,
Jim

This is a constraint induced by Maya then.

Well, in theory, all versions of PyQt4 should work with all versions of Qt4.

If you depend on a Qt feature that appeared in a certain version, this feature 
is available only, if PyQt4 is adapted to that feature and is compiled 
against a Qt version containing that feature. This is possible due to sips 
timeline feature and a complex version dependency scheme.  

In practise, you determine the lowest Qt version that you need to support, and 
build the newest sip/PyQt4 against it. Keep in mind, that sip/PyQt4 depends 
on the particular Python revision, it is build with. I cannot say anything 
about Mayas PyQt bindings, though.

Hth,
Pete
