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.

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.

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.
