[Plib-users] ssgaShape subclass -- how to handle ssgaType*?

[Daniel S. <djs...@uc...>]

I have been subclassing ssgaShapes to customize the shapes I am drawing.

I need to implement ssgaShape::getTypeName() -- should I do this with my 
own name or one of the existing ssg shape names? What are the 
implications of using my own name?

In a similar vein, my shapes implement a "Type" function, like this

#define _SSGA_TYPE_RECT       0x00200000
inline int ssgaTypeRect  () { return _SSGA_TYPE_RECT   | ssgaTypeShape ();}

This simply follows the example of the shapes defined in ssg.

I'm not comfortable doing this, as it may be incompatible with future 
additions to the ssg shape collection. At the same time, I don't see 
where this type is used after I initialize the 'type' member in my 
class's constructor. Can anyone educate me on this?

Is there a cleaner way to do this, so that I won't have trouble if/when 
ssg adds new shape def's?
