Deserialization of QHash in PySide2

AndrzejO

Hello all

I'm starting with python for Qt and have quick question. How do you represent QList/QHash - I expect that these are "natural" python structures. But in that case I'm struggling a bit with deserialization of data. I have C++ application that stores some data that could be later read in C++ as (after some trivial reading of magic, version, ...):

QVariantHash header;
in >> header; // 'in' is a QDataStream

How would one do that in python? Direct translation (with header being empty dictionary) results in an error that __rshift__ accepts only following:

PySide2.QtCore.QBitArray
PySide2.QtCore.QByteArray
PySide2.QtCore.QDate
PySide2.QtCore.QDateTime
PySide2.QtCore.QEasingCurve
PySide2.QtCore.QLine
PySide2.QtCore.QLineF
PySide2.QtCore.QLocale
PySide2.QtCore.QMargins
PySide2.QtCore.QMarginsF
PySide2.QtCore.QPoint
PySide2.QtCore.QPointF
PySide2.QtCore.QRect
PySide2.QtCore.QRectF
PySide2.QtCore.QSize
PySide2.QtCore.QSizeF
PySide2.QtCore.QTime
PySide2.QtCore.QUrl
PySide2.QtCore.QUuid
PySide2.QtCore.QRegularExpression
PySide2.QtCore.QRegExp
PySide2.QtCore.QTimeZone
PySide2.QtCore.QVersionNumber

and there is no QDataStream.readHash or something like that. Do I need to take a peek at how it is done and do it myself by pieces (would prefer not to rely on the particular implementation - which could change between Qt versions).

I'd appreciate some help with this.

With regards
Andrzej

Hi,

Interesting use case. I would recommend asking this question to the PySide mailing list. You'll find there PySide2 developers/maintainers. This forum is more user oriented.
