[PyQt] Bug in QTableView.setModel()

[Aaron Digulla]

Hello,

When I create a python implementation of a table model derived from
QAbstractTableModel and use that in QTableView.setModel(), I have
spurious errors afterwards: Sometimes, the redraw doesn't work,
sometimes, I can't select anything, etc.

The root cause is that setModel() doesn't increment the usage counter of
the python class passed in, so Python will GC it if I don't save a
pointer elsewhere.

My quick fix was to write a helper class that extends QTableView and
saves a reference to the model in setModel() but it would be better if
that could be handled in the SIP layer.

Regards,
