      Wrapping classes which return shared pointers in a virtual method leads to this message

       

       #error: CppGenerator::writeVirtualMethodNative: B::genA(): Could not find a minimal constructor for type 'QSharedPointer<A >'. This will result in a compilation error.

      This is the header file which should be wrapped:

      #ifndef TEST_H
#define TEST_H

#include <QtCore/QSharedPointer>

// if uncommented, you will get the following error when calling shiboken
// #error:  CppGenerator::writeVirtualMethodNative: B::genA(): Could not find a minimal constructor for type 'QSharedPointer<A >'. This will result in a compilation error.
#define SHIBOKEN_ERROR

class A
{
    public:
        int a;
        A(int _a);
        virtual ~A();
};

class B
{
    public:
        int b;
        B(int _b);
        virtual ~B();
        void doSomething(QSharedPointer<A> a);
#ifdef SHIBOKEN_ERROR
        virtual
#endif
        QSharedPointer<A> genA();
};

#endif
 

      and this is the typesystem xml file:

      <!--?xml version="1.0"?-->
 <typesystem package="ptest">
 <load-typesystem name="typesystem_core.xml" generate="no" />

<smart-pointer-type name="QSharedPointer" type="shared" getter="data" />

<object-type name="A" />
 <object-type name="B" />
 </typesystem>
