[PyKDE] Handling exceptions in SIP

[Denis S. Otkidach]

I hope it's correct place to ask general questions about SIP.

Am I correct that automatic exception handling in SIP is useless?  I see
several problems with it.  First, the code for method with signature
"void error() throw (exception);" is:

    try
    {
    sipCpp -> Test::error();
    }
    catch (exception &e)
    {
            /* Hope that there is a valid copy ctor. */ 
            exception *sipCpp = new exception(e);

            sipRaiseClassException(sipClass_exception,sipCpp);
            return NULL;
    } 

The copy of exception is generated and important information is lost (in
fact, std::exception used above is never raised itself, but holds what()
virtual method redefined in subclasses).

Second, the only way to map C++ exception to python object is wrapping
exception class, %MappedType doesn't work.  But then I see no way to
subclass standard Exception class.

Am I missing something?
