SoGroup — base class for all group nodes

SoGLRenderAction,SoCallbackAction,SoGetBoundingBoxAction,SoHandleEventAction,SoRayPickAction
          Traverses each child in order.

     SoGetMatrixAction
          Does nothing unless the group is in the middle of the path chain the action is being  applied  to.  If
          so, the children up to and including the next node in the chain are traversed.

     SoSearchAction
          If searching for group nodes, compares with this group. Otherwise, continues to search children.

     SoWriteAction
          Writes  out the group node. This method also deals with any field data associated with the group node.
          As a result, this method is used for most subclasses of SoGroup as well.

       This  node defines the base class for all group nodes. SoGroup is a node that contains an ordered list of
       child nodes. The ordering of the child nodes represents the  traversal  order  for  all  operations  (for
       example, rendering, picking, and so on). This node is simply a container for the child nodes and does not
       alter  the  traversal  state  in any way. During traversal, state accumulated for a child is passed on to
       each successive child and then to the parents of the group (SoGroup does not push or pop traversal  state
       as SoSeparator does).

SoGroup()
          Creates an empty group node.

                         SoGroup(intnChildren)
          Constructor  that  takes  approximate  number  of  children.  Space  is  allocated for pointers to the
          children, but the group does not contain any actual child nodes.

     voidaddChild(SoNode*child)
          Adds a child as last one in group.

     voidinsertChild(SoNode*child,intnewChildIndex)
          Adds a child so that it becomes the one with the given index.

     SoNode*getChild(intindex)const
          Returns pointer to child node with the given index.

     intfindChild(constSoNode*child)const
          Finds index of given child within group. Returns -1 if not found.

     intgetNumChildren()const
          Returns number of children.

     voidremoveChild(intindex)
          Removes child with given index from group.

     voidremoveChild(SoNode*child)
          Removes first instance of given child from group.

     voidremoveAllChildren()
          Removes all children from group.

     voidreplaceChild(intindex,SoNode*newChild)
          Replaces child with given index with new child.

     voidreplaceChild(SoNode*oldChild,SoNode*newChild)
          Replaces first instance of given child with new child.

     staticSoTypegetClassTypeId()
          Returns type identifier for this class.
