[PySide] Ann: porting PySide to Qt5

[Jumaroch Belpecajo]

Hi Christian,



Last year, I started a porting of PySide to Qt5.

I only worked on the QtCore module, but I succedded in having 99% of all
classes and methods sucessfully wrapped.

I made a quick python test with a custom class derived from QObject with
signal/slot connections, and everything was working well.

I didn't have time to continue with the QtGui porting since it's a huge
task due the QtWidgets modules split.



If you are interested, I can generate the patches and send them to you,
especially the ones related to "tricky" qt metaobject stuff :)

FYI, I used an old version of PySide (1.0.9), but hopefully there is not
much difference with the current version (even if in this version,
api-extractor was not yet merged with the shiboken module).



IIRC, the main difficulties were:

- replace Zc:wchar_t- with Zc:wchar_t to use the native type instead of
ushort typedef (Qt5 is now compiled with wchar_t by default)

- need explicit cast in qstring_convertsions:
QString::fromUtf16(reinterpret_cast<const ushort*>(unicode)

- headergenerator: need to order customized converter, due to dependencies:
QString before QVariant before QStringRef, ...

- replace deprecated macro qdoc with Q_QDOC (otherwise, the metaObject
method is not seen)



Cheers,

Romain
