NAME
SoLineWidthElement
SYNOPSIS
#include <Inventor/elements/SoLineWidthElement.h> Inherits SoFloatElement. Inherited by SoGLLineWidthElement.
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). - Public Member Functions

- 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.

- 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.

- Returns the default linewidth value if no value has been set
explicitly. - Referenced by init().
