Detailed Description

The SoLineWidthElement class changes the line width setting of the render state.

Requests from the scene graph to change the line width when rendering line primitives will be made through this element, which forwards it to the appropriate native call in the underlying rendering library.

Subsequent nodes rendering line primitives will use the width setting (for instance SoLineSet nodes).

Destructor.

Member Function Documentation

createInstance()

void * SoLineWidthElement::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.

get()

float SoLineWidthElement::get ( SoState *const state )

static

Returns the current line width value.

getClassStackIndex()

int SoLineWidthElement::getClassStackIndex ( void )

static

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

getClassTypeId()

SoType SoLineWidthElement::getClassTypeId ( void )

static

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

getDefault()

float SoLineWidthElement::getDefault ( void )

static

Returns the default line width value if no value has been set explicitly.

init()

void SoLineWidthElement::init ( SoState * state )

virtual

Initializes the element to its default value. The default value is 0.0.

Reimplemented from SoFloatElement.

Reimplemented in SoGLLineWidthElement.

initClass()

void SoLineWidthElement::initClass ( void )

static

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

set() [1/2]

void SoLineWidthElement::set ( SoState *const state, const float lineWidth )

static

Set up the current state's lineWidth value.

set() [2/2]

void SoLineWidthElement::set ( SoState *const state, SoNode *const node, const float lineWidth )

static

Set up the current state's lineWidth value.
