Starting with some recent release of SIP, some of my exposed C++
classes are being marked as abstract to Python. Obviously, some
change in SIP requires that I make some changes to my .sip files. I
haven't been able to figure it out. Any hints?

Is there a reason that
QApplication ( int argc, char ** argv, bool )
is not exposed to Python in PyQt. We could use it.

Yes, it works both ways. In my
Using sip.transfer(), as Phil suggested, keeps the destructor of my
object created by clone() from being destroyed. However, my object
is still not useable as it can't find the Python implemented methods
when it is called from C++ after return of clone.
Poking around, I found that

You must either keep a reference or transfer ownership to C++ using
sip.transfer() - and make sure you call the C++ dtor explicitly at
some stage to avoid a memory leak.
I'll try sip.transfer().

What if you implement __str__() for your exception class?
I suppose you mean to implement this in the .sip file. Can you
point to an example of doing this in the PyQt sources?
grep __str__ *.sip = qbytearray.sip,
18 matches
