NAME

       SoFontStyle -

       The SoFontStyle class changes the appearance of fonts for text
       rendering nodes.

       Successive text rendering nodes will use fonts with the style settings
       of this node, if a font with the given settings can be found and loaded
       from the system.

SYNOPSIS

       #include <Inventor/nodes/SoFontStyle.h>

       Inherits SoFont.

Detailed Description

       The SoFontStyle class changes the appearance of fonts for text
       rendering nodes.

       Successive text rendering nodes will use fonts with the style settings
       of this node, if a font with the given settings can be found and loaded
       from the system.

       If the specified font style cannot be found on the client system, a
       default fallback will be used. So the application programmer must
       consider SoFontStyle nodes as nodes giving hints about font settings,
       as you are not guaranteed to get exactly what you want.

       Currently the SERIF family is mapped to ’Times New Roman’, SANS is
       mapped to ’Arial’ and TYPEWRITER is mapped to ’Courier New’.

       Please note that this node is inheriting SoFont. Previous font settings
       in a branch will therefore be overwritten with the default values of
       SoFont if an empty SoFontStyle node is inserted in the branch.

       NB! This node is provided for reasons of compatibility with Open
       Inventor 2.1 but will in most cases result in the default font being
       rendered. It is highly recommended to use the SoFont node instead.

       FILE FORMAT/DEFAULTS:

           FontStyle {
               name ’defaultFont’
               size 10
               family SERIF
               style ()
           }

       Since:
           Inventor 2.1

Member Function Documentation

   void SoFontStyle::initClass (void) [static] Sets up initialization for data
       common to all instances of this class, like submitting necessary
       information to the Coin type system.
       Reimplemented from SoFont.

   SbString SoFontStyle::getFontName (void) const Returns a system-specific
       text string to use for font loading, based on the style settings of
       this node.
   void SoFontStyle::doAction (SoAction * action) [virtual] This function
       performs the typical operation of a node for any action.
       Reimplemented from SoFont.

   void SoFontStyle::getBoundingBox (SoGetBoundingBoxAction * action)
       [virtual] Action method for the SoGetBoundingBoxAction.
       Calculates bounding box and center coordinates for node and modifies
       the values of the action to encompass the bounding box for this node
       and to shift the center point for the scene more towards the one for
       this node.

       Nodes influencing how geometry nodes calculates their bounding box also
       overrides this method to change the relevant state variables.

       Reimplemented from SoFont.

   void SoFontStyle::GLRender (SoGLRenderAction * action) [virtual] Action
       method for the SoGLRenderAction.
       This is called during rendering traversals. Nodes influencing the
       rendering state in any way or who wants to throw geometry primitives at
       OpenGL overrides this method.

       Reimplemented from SoFont.

   void SoFontStyle::callback (SoCallbackAction * action) [virtual] Action
       method for SoCallbackAction.
       Simply updates the state according to how the node behaves for the
       render action, so the application programmer can use the
       SoCallbackAction for extracting information about the scene graph.

       Reimplemented from SoFont.

   void SoFontStyle::pick (SoPickAction * action) [virtual] Action method for
       SoPickAction.
       Does common processing for SoPickAction action instances.

       Reimplemented from SoFont.

   void SoFontStyle::getPrimitiveCount (SoGetPrimitiveCountAction * action)
       [virtual] Action method for the SoGetPrimitiveCountAction.
       Calculates the number of triangle, line segment and point primitives
       for the node and adds these to the counters of the action.

       Nodes influencing how geometry nodes calculates their primitive count
       also overrides this method to change the relevant state variables.

       Reimplemented from SoFont.
