[PySide] Shiboken not generating right code for member pointers?

[Luiz Vitor Martinez Cardoso]

Dear,

I'm new to PySide/Shiboken but I'm enjoying it!

To be honest I don't like the lack of good and reasonable documentation and
examples.

I decided to create a git repo (
https://github.com/Grabber/shiboken-binding-examples) together my friend *Yann
Lanthony *to archive all the solutions we get to work in our lab. At the
end we plan to write a very detailed and extensive article including
everything from the installation (Win, OSX and Linux) to the binding
process itself.

Today the master's help to solve a little trouble.

I'm trying to wrap the following code:

class LIBFOO_EXPORT CustomType
> {
>


> public:
>         CustomType() {}
>         virtual ~CustomType() {}
>         CustomType(const CustomType&) {}
>         int a;
>         int * b;
> };


Using the following TypeSystem:

<?xml version="1.0"?>
> <typesystem package="foo">
> <primitive-type name="int"/>
> <load-typesystem name="typesystem_core.xml" generate="no"/>
>     <object-type name="CustomType" />
> </typesystem>


But I'm getting some pointers erros in the generated wrapping code:

/home/lmvc/Projects/shiboken-binding-examples/build/foo/foo/customtype_wrapper.cpp:
> In function ‘PyObject* Sbk_CustomType_get_b(PyObject*, void*)’:
> /home/lmvc/Projects/shiboken-binding-examples/build/foo/foo/customtype_wrapper.cpp:166:33:
> error: invalid conversion from ‘int*’ to ‘int’ [-fpermissive]
> /home/lmvc/Projects/shiboken-binding-examples/build/foo/foo/customtype_wrapper.cpp:
> In function ‘int Sbk_CustomType_set_b(PyObject*, PyObject*, void*)’:
> /home/lmvc/Projects/shiboken-binding-examples/build/foo/foo/customtype_wrapper.cpp:187:33:
> error: invalid conversion from ‘int*’ to ‘int’ [-fpermissive]
> /home/lmvc/Projects/shiboken-binding-examples/build/foo/foo/customtype_wrapper.cpp:189:18:
> error: invalid conversion from ‘int’ to ‘int*’ [-fpermissive]
> make[2]: *** [foo/CMakeFiles/foo.dir/foo/customtype_wrapper.cpp.o] Error 1



The generated wrapping code was:

static PyObject* Sbk_CustomType_get_b(PyObject* self, void*)
> {
>     ::CustomType* cppSelf = 0;
>     SBK_UNUSED(cppSelf)
>     if (!Shiboken::Object::isValid(self))
>         return 0;
>     cppSelf =
> ((::CustomType*)Shiboken::Conversions::cppPointer(SbkfooTypes[SBK_CUSTOMTYPE_IDX],
> (SbkObject*)self));
>     int cppOut_local = cppSelf->b;
>     PyObject* pyOut =
> Shiboken::Conversions::copyToPython(Shiboken::Conversions::PrimitiveTypeConverter<int>(),
> &cppOut_local);
>     return pyOut;
> }
> static int Sbk_CustomType_set_b(PyObject* self, PyObject* pyIn, void*)
> {
>     ::CustomType* cppSelf = 0;
>     SBK_UNUSED(cppSelf)
>     if (!Shiboken::Object::isValid(self))
>         return 0;
>     cppSelf =
> ((::CustomType*)Shiboken::Conversions::cppPointer(SbkfooTypes[SBK_CUSTOMTYPE_IDX],
> (SbkObject*)self));
>     if (pyIn == 0) {
>         PyErr_SetString(PyExc_TypeError, "'b' may not be deleted");
>         return -1;
>     }
>     PythonToCppFunc pythonToCpp;
>     if (!(pythonToCpp =
> Shiboken::Conversions::isPythonToCppConvertible(Shiboken::Conversions::PrimitiveTypeConverter<int>(),
> (pyIn)))) {
>         PyErr_SetString(PyExc_TypeError, "wrong type attributed to 'b',
> 'int' or convertible type expected");
>         return -1;
>     }
>     int cppOut_local = cppSelf->b;
>     pythonToCpp(pyIn, &cppOut_local);
>     cppSelf->b = cppOut_local;
>     return 0;
> }



Could someone tell me what is going on? I feel I have to inject some code
in TypeSystem but I don't know well...

I appreciate your help!

Best regards,
Luiz Vitor.
