Hi Phil,
I found a new bug in SIP (it used to work with a SIP from September 2007).
If you declare a class with a single constructor, you write %MethodCode
for that constructor, and you make
, for instance, which can contain very large
documents.

to be a problem here.
It's the kind of problems that re-surfaces now that Qt's .DLLs are
separated from .PYDs. In fact, till now I hadn't realized this was a
problem even if you installed Qt's .DLLs next to PyQt's .PYDs, but
that's the way Windows works...

to build it as a single static
_qt.pyd or with .pyd + Qt's .dll files. The former gives you a much
smaller installer file which might be a feature; the latter gives more
flexibility to final users. Either way it's fine.

I personally saw a *large* increase of interest in Python Windows
programmers since the consolidated installer was released. It would be a
shame to see a regression there.
I really hope you reconsider your choice.

() (the C++ function), Qt doesn't
know how to cooperate with Python for CTRL+C, and this is why it does
not work. I don't think there's a good way to make it work; you may
want to see if you can handle it through a global event filter.

the QObject dies, the Python object is
flagged as invalid, and any usage of it results in a RuntimeError;
moreover, you can check for this invalid condition through
sip.isdeleted().
Thus, I'm not sure what you are speaking of.

anything more than it would be done one opcode later when the method
exits and its locals are destroyed. In fact, calling takeItem() without
binding its return value to a name achieves the same effect and it is
clearer.
Thanks again for a nice article!
