Hi,
I have a little problem, i can't find a way to call a pure virtual function
from C++ on a Python object taking a specific class object as argument :
// Base Class for a component
class BaseCmp
{
public:
~BaseCmp() {};
};
// Base class
class Base
{
public:
Base() {};
virtual ~Base() {};
virtual void testVirtualPure( BaseCmp* pBaseCmp ) = 0;
};
struct BaseWrap : Base, bp::wrapper<Base>
{
void testVirtualPure( BaseCmp* pBaseCmp )
{
this->get_override("testVirtualPure")( pBaseCmp );
}
};
// Module TestScript
BOOST_PYTHON_MODULE(test)
{
// BaseCmp Class exposition
bp::class_<BaseCmp,boost::noncopyable>("BaseCmp", bp::no_init)
;
// Base Class Wrapper exposition
bp::class_<BaseWrap, boost::noncopyable>("Base")
.def( "testVirtualPure", bp::pure_virtual(
&Base::testVirtualPure ) )
;
}
I need to call my testVirtualPure function from C++ side :
BaseCmp* bc = BaseCmp();
Base* b = Base();
b->testVirtualPure( bc );
But this causes an error :
TypeError: No to_python (by-value) converter found for C++ type: class
BaseCmp
Does someone know how i can do that ?
Thanks a lot
