When I open a dxf file ( which contains many blocks and line entitys),

I want to know each information (color ,vector ) of objects for
1. all entities
2. all blocks

I notice that RS_Graphic -> RS_BlockList blockList might fetch the block list ?
                  RS_GraphicView -> RS_EntityContainer* container; // Holds a pointer to all the enties

are these the collection of all entities and all blocks ?  if that,  I am just confused why not there are defined in one class .

BTW,  I want to change the color by programming.  how to do that ?

Thanks.
