Detailed Description

The SoConeDetail class contains information about the parts of a SoCone shape.

Instances of this class are used for storing information about hit points on cone geometry after pick operations, and for storing information returned to tessellation callbacks.

Destructor.

Member Function Documentation

SoType SoConeDetail::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 SoConeDetail::getClassTypeId (void) [static]

Returns the type for this class.

Reimplemented from SoDetail.

void SoConeDetail::initClass (void) [static]

Initialize relevant common data for all instances, like the type system.

Reimplemented from SoDetail.

SoDetail * SoConeDetail::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.

void SoConeDetail::setPart (const intpartarg)

Set the part of a cone which was selected. A cone has two different conceptual parts; SoCone::SIDES or SoCone::BOTTOM.

int SoConeDetail::getPart (void) const

Returns selected cone part, either SoCone::SIDES or SoCone::BOTTOM.

Member Data Documentation

int SoConeDetail::part [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
