I have used the same reference and also this suggestion for including the
other attributes shown here:
http://stackoverflow.com/questions/11448735/boostpython-export-custom-exception-and-inherit-from-pythons-exception
However, this doesn't solve my problem.
It works fine when I throw the MyException in C++, but when I raise the
MyCPPException in Python, the translator is not called (which makes sense), so
the attribute 'cause' does not change.
Actually, before I throw the MyException for the first time in C++,
MyCPPException does not have the attribute 'cause' at all.
Of course.
This issue should be the same, if I set the exception with PyErr_SetObject,
since the translator is not called, when I 'raise' it.
Very likely the SetString uses SetObject under the hood, but I never used
SetObject.
I'd try to:
*) As you were writing before, declare a C++ class MyException: public
std::exception {
MyException();
MyException(int code, const std::string &string);
int code();
const char* what();
int errorCode;
std::string errorMessage;
};
*) Wrap it as a bpy::class_ so you can use it like a standard exception with
all the attributes you need.
*) Register an exception translator as defined before. Maybe the to-python
conversion performed in the exception translator does work even if you have
wrapped MyException as a standard class.
