linked list for virtual base classes??

Recommended Posts

Hi, Just working on the Renderer object for my small gaming library... I have virtual base classes defined in the static library, then implemented in a DLL file which the user of my library must use... I've got most things working properly, HOWEVER I have a few objects in the static library which I want to contain a linked list (or array) of interfaces....??? sorry if my explanation sucks...I'll try it this way..
    
class Font
{
  virtual render() = 0;

};

//the following class resides in my rendering DLL

class OGL2DFont : public Font
{
   render(); //define the inherited pure virtual function

};

//now I WANT to do the following but because base is

//a pure virtual class, the compiler won't let it happen

class fontManager
{
  private:
     Font    *m_bases; //pointer to a base array


};
    
Where I'm trying to go with this is I can just hold an array of Font objects which are then implemented inside my opengl renderer DLL.. any ideas?? Or am I stuck with the "hack" solution of NOT making the base class pure virtual..(ie. just using regular virtual instead of a pure virtual definition).. thanks in advance...
