I've got a couple quick questions about SIP's handling of object destruction.
The docs for sip.setdeleted says
This marks the C++ instance or C structure as having been destroyed or
returned to the heap so that future references to it raise an exception rather
than cause a program crash. Normally SIP handles such things automatically, but
there are circumstances where this isn't possible. obj is the Python object.
How does SIP handle this situation "automatically?" I don't see anything going
on in the release_XXX methods in my class wrappers, other than
delete reinterpret_cast<XXX *>(ptr);
Also, some of my classes have a Destroy method whose implementation is to just
Without the SIP wrappers defining a virtual destructor of their own, is there
any way for SIP to recognize that it should mark any existing Python instances
