A ComplexShape node for Inventor/Coin that defines an arrow or pointer.
This class combines a cylinder with 0,1, or 2 cones that serve as arrow heads. This makes it easy to add arrows to an Inventor scene without defining the pieces separately. The lengths and radii of the various pieces can all be customized.

| SoArrow::~SoArrow | ( | ) | [private, virtual] |
Deletes the child nodes that make up this node.

| void SoArrow::addPart | ( | Part | part | ) |
Turns on a part of the arrow.
Definition at line 100 of file SoArrow.cpp.
| void SoArrow::generateChildren | ( | ) | [private, virtual] |
This is called once to generate the child nodes that make up this complex shape. The child nodes consist of a cylinder, transforms, and cones. A calculator node caluculates the height of the cylinder from the total height field and the height of any present arrowheads.

Returns whether a given part is on or off.

| void SoArrow::initClass | ( | ) | [static] |
Initializes the SoArrow class. This is a one-time thing that is done after database initialization and before any instance of this class is constructed.
