[osg-users] osg::ref_ptr problem

[Panagiotis Papadakos]

Hello.

I have a vector with elements of osg::ref_ptr<SubClass>, where SubClass 
inherits from baseClass,
and I want to create a vector with elements osg::ref_ptr<BaseClass>. How can I 
do it?
 
BaseClassVector vec;
SubClassVector::iterator item = m_Items.begin();
for(;item != m_Items.end();++item) {
        vec.push_back(*item);
}
G++ throws the following error for this code:
no matching function for call to ‘std::vector<osg::ref_ptr<BaseClass>, 
std::allocator<osg::ref_ptr<BaseClass> > 
>::push_back(osg::ref_ptr<SubClass>&)’

Thanks.
