## Detailed Description

The SoMultiTextureEnabledElement class is an element which stores whether texturing is enabled or not.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

  Coin 2.2

## Constructor & Destructor Documentation

## SoMultiTextureEnabledElement()

SoMultiTextureEnabledElement::SoMultiTextureEnabledElement | ( | void |  | ) |

protected

Constructor.

## ~SoMultiTextureEnabledElement()

SoMultiTextureEnabledElement::~SoMultiTextureEnabledElement | ( | void |  | ) |

protected virtual

Destructor.

## Member Function Documentation

## getClassTypeId()

SoType SoMultiTextureEnabledElement::getClassTypeId | ( | void |  | ) |

static

This static method returns the SoType object associated with objects of this class.

## getClassStackIndex()

int SoMultiTextureEnabledElement::getClassStackIndex | ( | void |  | ) |

static

This static method returns the state stack index for the class.

## createInstance()

void * SoMultiTextureEnabledElement::createInstance | ( | void |  | ) |

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Creates a new instance of the class type corresponding to the SoType object.

## initClass()

void SoMultiTextureEnabledElement::initClass | ( | void |  | ) |

static

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

## init()

void SoMultiTextureEnabledElement::init | ( | SoState * | state | ) |

virtual

This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.

Reimplemented from SoElement.

Reimplemented in SoGLMultiTextureEnabledElement.

## set() [1/3]

void SoMultiTextureEnabledElement::set | ( | SoState * | state,
|  | SoNode * | node,
|  | const int | unit,
|  | const SbBool | enabled )

static

Sets the state of this element.

## get()

SbBool SoMultiTextureEnabledElement::get | ( | SoState * | state,
|  | const int | unit = 0 )

static

Return current state of this element for unit.

## setElt()

void SoMultiTextureEnabledElement::setElt | ( | const int | unit,
|  | const int | mode_in )

virtual

virtual element set function.

Reimplemented in SoGLMultiTextureEnabledElement.

## push()

void SoMultiTextureEnabledElement::push | ( | SoState * | state | ) |

virtual

This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.

Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().

Reimplemented from SoElement.

Reimplemented in SoGLMultiTextureEnabledElement.

## matches()

SbBool SoMultiTextureEnabledElement::matches | ( | const SoElement * | element | ) | const

virtual

This function returns `TRUE` is the element matches another element (of the same class), with respect to cache validity.

If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function.

Implements SoElement.

## copyMatchInfo()

SoElement * SoMultiTextureEnabledElement::copyMatchInfo | ( | void |  | ) | const

virtual

This function creates a copy of the element that contains enough information to enable the matches() function to work.

Used to help with scene graph traversal caching operations.

Implements SoElement.

## getEnabledUnits()

const SbBool * SoMultiTextureEnabledElement::getEnabledUnits | ( | SoState * | state,
|  | int & | lastenabled )

static

Returns a pointer to a boolean array. TRUE means unit is enabled and that texture coordinates must be sent to the unit. lastenabled is set to the last enabled unit.

## getActiveUnits()

const SoMultiTextureEnabledElement::Mode * SoMultiTextureEnabledElement::getActiveUnits | ( | SoState * | state,
|  | int & | lastenabled )

static

Returns the mode of all units. Also returns the last enabled unit in lastenabled.

Since
  Coin 2.5

## enableRectangle()

void SoMultiTextureEnabledElement::enableRectangle | ( | SoState * | state,
|  | SoNode * | node,
|  | const int | unit = 0 )

static

Enable RECTANGLE texture mode.

Since
  Coin 2.5

## enableCubeMap()

void SoMultiTextureEnabledElement::enableCubeMap | ( | SoState * | state,
|  | SoNode * | node,
|  | const int | unit = 0 )

static

Enable CUBEMAP texture mode.

Since
  Coin 2.5

## enableTexture3()

void SoMultiTextureEnabledElement::enableTexture3 | ( | SoState * | state,
|  | SoNode * | node,
|  | const int | unit = 0 )

static

Enable Texture3 texture mode.

Since

## getMode()

SoMultiTextureEnabledElement::Mode SoMultiTextureEnabledElement::getMode | ( | SoState * | state,
|  | const int | unit = 0 )

static

## disableAll()

void SoMultiTextureEnabledElement::disableAll | ( | SoState * | state | ) |

static
