Detailed Description

The SoLineWidthElement class changes the linewidth setting of the render state.

Requests from the scenegraph to change the linewidth 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).

SoLineWidthElement::~SoLineWidthElement  )  [protected, virtual]
 

Destructor.


Member Function Documentation

void SoLineWidthElement::initClass void   )  [static]
 

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

Reimplemented from SoFloatElement.

Reimplemented in SoGLLineWidthElement.

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.

void SoLineWidthElement::set SoState *const  state,
SoNode *const  node,
const float  lineWidth
[static]
 

Set up the current state's lineWidth value.

void SoLineWidthElement::set SoState *const  state,
const float  lineWidth
[static]
 

Set up the current state's lineWidth value.

float SoLineWidthElement::get SoState *const  state  )  [static]
 

Returns the current line width value.

float SoLineWidthElement::getDefault void   )  [static]
 

Returns the default linewidth value if no value has been set explicitly.
