Another wa would be to save all objects which pass through SIP in map
(QObject -> Python wrapper), connect to the destroyed(QObject) signal
and check the state when it is emitted. Does SIP notice when the python
wrapper is destroyed? If not, it's probab

Thanks, to you, too. :)
The difference is that in C++ the effect of
the bug is a memory leak, but in PyQt it is often a crash.
This part is what bugs me, and surely caught every PyQt user in

As it is, the class pointer is copied into the view class and then python

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
