SoTextDetail.3coin2

NAME

SoTextDetail -

The SoTextDetail stores information about a character in a string.

Instances of this class are used for storing information about hit points on textual 2D or 3D geometry after pick operations, and for storing information returned to tessellation callbacks.

SYNOPSIS

#include <Inventor/details/SoTextDetail.h>

Inherits SoDetail.

Detailed Description

The SoTextDetail stores information about a character in a string.

Instances of this class are used for storing information about hit points on textual 2D or 3D geometry after pick operations, and for storing information returned to tessellation callbacks.

Constructor & Destructor Documentation

SoTextDetail::SoTextDetail (void)Constructor sets up an 'empty' detail; all indices are set to -1 to indicate this.

SoTextDetail::~SoTextDetail () [virtual]Destructor. This class does not allocate any extra resources, so no actions are taken.

Member Function Documentation

void SoTextDetail::initClass (void) [static]Initialize relevant common data for all instances, like the type system.

Reimplemented from SoDetail.

SoDetail * SoTextDetail::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.

int SoTextDetail::getStringIndex (void) constReturns the index of the string where a character was hit / generated, from a set of multiple strings.

int SoTextDetail::getCharacterIndex (void) constReturns the index of the character in the string which was hit.

int SoTextDetail::getPart (void) constFor SoText3, returns the part id of the text geometry. The id numbers matches those specified in the SoText3::Part enumeration.
