Did you try:
template<typename T>
struct MyObj : T
{
~MyClass()
{
// handle deletion; output something to stderr, console, debugger,
file, etc.
}
};
{
osg::ref_ptr<MyObj<osg::Group> > pobj = new osg::Group;
// use pobj
} // should call destructor here.
Instead of a template class, you may derive directly from
osg::Referenced or osg::Object as the most common base types, but then
you lose full functionality of actual type and need to cast.
I didn't test the code (have no osg neither a compiler on my Omnia
PDA), but I'd expect that to work regardless of project, as long as
base type has a virtual destructor and gets deleted (in case delete is
applied onto pointer to base type, which is the case in osg).
