NAME
SoCylinderDetail -SYNOPSIS
#include <Inventor/details/SoCylinderDetail.h>
Inherits SoDetail.
Detailed Description
The SoCylinderDetail class contains information about the parts of a SoCylinder shape.
Instances of this class are used for storing information about hit points on cylinder geometry after pick operations, and for storing information returned to tessellation callbacks.

Member Function Documentation
SoType SoCylinderDetail::getTypeId (void) const [virtual]
Returns the type identification of a detail derived from a class inheriting SoDetail. This is used for run-time type checking and 'downward' casting.
Usage example:
void fuhbear(SoDetail * detail) { if (detail->getTypeId() == SoFaceDetail::getClassTypeId()) { // safe downward cast, know the type SoFaceDetail * facedetail = (SoFaceDetail *)detail; } return; // ignore if not a SoFaceDetail }
For application programmers wanting to extend the library with new detail classes: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through Inventor/nodes/SoSubDetail.h: SO_DETAIL_SOURCE and SO_DETAIL_INIT_CLASS.
Implements SoDetail.
SoType SoCylinderDetail::getClassTypeId (void) [static]
Returns the type for this class.
Reimplemented from SoDetail.
void SoCylinderDetail::initClass (void) [static]
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoDetail.
Referenced by SoDetail::initClasses().
SoDetail * SoCylinderDetail::copy (void) const [virtual]
Return a deep copy of ourself.
Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you must make sure that both the Coin DLL and the application executable is using the same instance of a C Run-Time (CRT) library. Otherwise, you will get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes.
Implements SoDetail.
References part, and SoCylinderDetail().
void SoCylinderDetail::setPart (const int partarg)
Set the part of a cylinder which was selected. A cylinder has three different conceptual parts; SoCylinder::SIDES, SoCylinder::TOP or SoCylinder::BOTTOM.
References part.
int SoCylinderDetail::getPart (void) const
Returns selected cylinder part.
References part.
Member Data Documentation
int SoCylinderDetail::part [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Referenced by copy(), getPart(), and setPart().
