Detailed Description
Base class for all group nodes.
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).
FILE FORMAT/DEFAULT
- Group {
ACTION BEHAVIOR
- 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.

Constructor & Destructor Documentation
| SoGroup::SoGroup | ( | ) |
Creates an empty group node.
| SoGroup::SoGroup | ( | int | nChildren | ) |
Constructor that takes approximate number of children.
Space is allocated to contain the specified number of children, but the group does not contain any actual child nodes.
