[osg-users] Problem with derived class from osg::Drawable

[Saravanan Sivaprahasam]

Hi,
     i derived a class from osg::Drawable. When ever i try to create an 
instance, the compiler is giving me the following error

error C2259: 'TDrawable' : cannot instantiate abstract class
1>        due to following members:
1>        'osg::Object *osg::Object::cloneType(void) const' : is abstract
1>        C:\Program Files\OpenSceneGraph\include\osg/Object(80) : see 
declaration of 'osg::Object::cloneType'
1>        'osg::Object *osg::Object::clone(const osg::CopyOp &) const' : is 
abstract
1>        C:\Program Files\OpenSceneGraph\include\osg/Object(84) : see 
declaration of 'osg::Object::clone'

Here is the actual code


Code:

class TDrawable : public osg::Drawable
{
public:
        // Constructor
        TDrawable() {}
         
        // Destructor
        ~TDrawable() {}

        virtual void drawImplementation (osg::RenderInfo &renderInfo) const
        {
        
        }

};

int main()
{
       ..............

        TDrawable TBarDraw;

        ..................
        ..................

}





Please help me to solve this problem


Thank you!

Cheers,
