Hi,
In case you are on M$-WIndows, I'd like to mention a nasty bug in Visual C++
2012
that took me days to dig out of google:
http://bugs.python.org/issue17797
In short: when you embedd the python interpreter into an application compiled
as "WINDOWS" (not as "CONSOLE"), the operating system doe
ng symbols:

> (?sipTypeDef_hello_MyNamespace@@3U_pyqt4ClassTypeDef@@A)
> release\hello.dll : fatal error LNK1120: 1 unresolved externals
> What's the proper way to describe this to sip?
Hi,
Are you really compiling and linking all C++ files generated by SIP?
Best Regards,
Mathias Born

Thanks.
Using VS2012, it now works out of the box with python 3.3.2 and Qt 5.1.
Have not tested the mingw stuff yet.

The log_window.ui instantiates a QHBoxLayout, with all margins set to the same

However, my Qt5 build created libraries named "Qt5Gui.lib" and so on, not

If I replace

If "statusbar" were given an extra reference to "window", the crash could be
avoided,
but then "del window" would not delete the window anymore. This would be safer,

o debugg your entire project is slim. On a mailing list
such as this one, the best way is to reduce the problem to a self
contained, minimum size test case which reproduces the bug.

The names of these objects, which are both "i", come into existence at
different times. While this is perfectly legal C++, it obviously
obfuscates your program. Just naming them differently should a
to get hold of the wrapper instance. This instance is then used in the
C++ code. It transparently forwards method calls to the Python part.
(That's why it was so important to have the wrapper "re-throw" Python
exceptions as C++ exceptions.)
Thanks to "sipTransfer(obj, Py_None)"
working properly anymore.
sip.h declares
typedef void (*sipVirtErrorHandlerFunc)(struct _sipSimpleWrapper *);
but the generated code containes error handlers that look like
void sipVEH_ltse_app_defaultVirtualErrorHandler(sip_gilstate_t, PyObject *)
And inside other functions they are referred to as, for example
extern void sipVEH_ltse_app_defaultVirtualErrorHandler(sip_gilstate_t, PyObject
*);

I believe you need to add

to the "parse" function
ith my sip file. Don't have time right now
to look at it, though.

C++ function creates a new object that will
be owned by the
Python side. I'd like to have another annotation which tells sip that the
Python implementation
of a class method creates a new object that will be owned by the C++ side.

(So an additional annotation is necessary to activate this behavior.)
I believe an extension like this would make sip a lot more useful

What about:

Is there an official way for my wrapper to have the "SIP_CPP_HAS_REF" flag set?
It would then automatically dispose its Python counterpart.

age the Python part myself.
In the sip sources, I can see a flag "SIP_CPP_HAS_REF" that
might just achieve that, but there appears to be no official
way to use it.

Hi,
During my first steps with SIP I discovered that it accepts
function parameters like
void example_function(const T&);
but not
void example_function(T const&);
It would be nice if SIP supported this, too.

Mathias Born
