What about queryList()/findChildren()? In my original code, the
C++-allocated instance was accessed through a queryList() call. It's
basically the same (getting a reference to a C++ instance never seen
before by Python), but I guess the annotation won't be enough...
You didn't answer this: is the annotation going to work also for the
queryList() / findChildren() case?
It would work if it was applied - but I haven't applied it to PyQt4.
I've applied it to those methods that are known to return an
internally generated instance.
findChildren() might or might not return an internally generated
instance, depending... on the instance. I guess that needs to be handled
in hand-generated code, right?
Sorry for being dense, but I still don't understand what I should do for
code that accesses C++-generated objects through findChildren() and add
attributes to them.
