NAME

       SoLineWidthElement -

       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.

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

   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 *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.
