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).

Constructor & Destructor Documentation

◆ ~SoLineWidthElement()

SoLineWidthElement::~SoLineWidthElement ( )
protectedvirtual

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.

◆ init()

void SoLineWidthElement::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 SoFloatElement.

Reimplemented in SoGLLineWidthElement.

◆ set() [1/2]

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

Set up the current state's lineWidth value.

◆ set() [2/2]

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

Set up the current state's lineWidth value.

◆ get()

float SoLineWidthElement::get ( SoState *const  state)
static

Returns the current line width value.

◆ getDefault()

float SoLineWidthElement::getDefault ( void  )
static

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