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).

Member Function Documentation

SoType SoLineWidthElement::getClassTypeId (void) [static]

This static method returns the class type.

Reimplemented from SoFloatElement.

Reimplemented in SoGLLineWidthElement.

int SoLineWidthElement::getClassStackIndex (void) [static]

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

Reimplemented from SoFloatElement.

Reimplemented in SoGLLineWidthElement.

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.

Reimplemented in SoGLLineWidthElement.

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 *conststate, SoNode *constnode, const floatlineWidth) [static]

Set up the current state's lineWidth value.

void SoLineWidthElement::set (SoState *conststate, const floatlineWidth) [static]

Set up the current state's lineWidth value.

float SoLineWidthElement::get (SoState *conststate) [static]

Returns the current line width value.

float SoLineWidthElement::getDefault (void) [static]

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