[pygccxml-development] Implicit virtual functions in derived classes

[Julian S. <jul...@rs...>]

Hi,

I ran into the following problem with Py++ 0.9.0. Consider this class 
hierarchy:

class A
{
   public:
    virtual void foo() {}
};

class B: public A
{
};


This will not generate a wrapper for B even though B inherits A's 
virtual function. Now if I have the following Python code:

class C(B):
	def foo(self):
		print "C.foo"

... then when foo() is invoked on this instance on the C++ side of 
things, the Python code won't be executed as the wrapper is missing.

I managed to force generation of a wrapper for B, but even then it won't 
generate the necessary override code (virtual void foo, void 
default_foo, and the registration code.)

My workaround is currently to manually add any implicit virtual 
functions that I need to override, but this is cumbersome and 
error-prone. Is there a way to configure or patch Py++ so that this is 
not necessary?

Thanks in advance,

.Julian
