## 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).

## Constructor & Destructor Documentation

SoLineWidthElement::~SoLineWidthElement | ( | ) |  |

protectedvirtual

Destructor.

## Member Function Documentation

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.

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.
