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).

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.
