Default destructor.


Member Function Documentation

SoType SoVectorizePSAction::getTypeId void   )  const [virtual]
 

Returns the type identification of an action derived from a class inheriting SoAction. This is used for run-time type checking and "downward" casting.

Usage example:

  void bar(SoAction * action)
  {
    if (action->getTypeId() == SoGLRenderAction::getClassTypeId()) {
      // safe downward cast, know the type
      SoGLRenderAction * glrender = (SoGLRenderAction *)action;
    }
    return; // ignore if not renderaction
  }

For application programmers wanting to extend the library with new actions: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through Inventor/nodes/SoSubAction.h: SO_ACTION_SOURCE, SO_ACTION_INIT_CLASS and SO_ACTION_CONSTRUCTOR.

For more information on writing Coin extensions, see the SoAction class documentation.

Reimplemented from SoVectorizeAction.

SoType SoVectorizePSAction::getClassTypeId void   )  [static]
 

Returns the run-time type object associated with instances of this class.

Reimplemented from SoVectorizeAction.

void SoVectorizePSAction::addMethod const SoType  type,
SoActionMethod  method
[static]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Reimplemented from SoVectorizeAction.

void SoVectorizePSAction::enableElement const SoType  type,
const int  stackindex
[static]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Reimplemented from SoVectorizeAction.

const SoEnabledElementsList & SoVectorizePSAction::getEnabledElements void   )  const [protected, virtual]
 

Returns a list of the elements used by action instances of this class upon traversal operations.

Reimplemented from SoVectorizeAction.

SoEnabledElementsList * SoVectorizePSAction::getClassEnabledElements void   )  [static, protected]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

This method not available in the original OIV API, see SoSubAction.h for explanation.

Reimplemented from SoVectorizeAction.

SoActionMethodList * SoVectorizePSAction::getClassActionMethods void   )  [static, protected]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

This method not available in the original OIV API, see SoSubAction.h for explanation.

Reimplemented from SoVectorizeAction.

void SoVectorizePSAction::initClass void   )  [static]
 

Initializes the run-time type system for this class, and sets up the enabled elements and action method list.

Reimplemented from SoVectorizeAction.

void SoVectorizePSAction::setDefault2DFont const SbString fontname  ) 
 

Sets the default font name. This font will be used for rendering Text2-nodes which have no Font-nodes preceding them. The default value is "Courier".

const SbString & SoVectorizePSAction::getDefault2DFont void   )  const
 

Returns the default font name.

setDefault2DFont()

void SoVectorizePSAction::setGouraudThreshold const double  eps  ) 
 

Sets the Gouraud shading threshold. A threshold of 0.0 will disable Gouraud shading. A smaller value will yield more accurate Gouraud shading. Default is 0.1.

Since the postscript language has no support for Gouraud shaded triangles, each triangle will be split into subtriangles approximately of size eps postscript units. One postscript unit is approximately 1/72 inch.

SoPSVectorOutput * SoVectorizePSAction::getOutput void   )  const
 

Returns the SoPSVectorOutput used by this instance.

Reimplemented from SoVectorizeAction.

SoPSVectorOutput * SoVectorizePSAction::getPSOutput void   )  const
 

Returns the SoPSVectorOutput used by this instance. Provided for API compatibility with TGS HardCopy support.

void SoVectorizePSAction::printHeader void   )  const [protected, virtual]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoVectorizeAction.

void SoVectorizePSAction::printFooter void   )  const [protected, virtual]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Should be overridden by subclasses to print file footer data.

Reimplemented from SoVectorizeAction.

void SoVectorizePSAction::printBackground void   )  const [protected, virtual]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Should be overridden by subclasses to print background data.

Reimplemented from SoVectorizeAction.

void SoVectorizePSAction::printItem const SoVectorizeItem *  item  )  const [protected, virtual]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Should be overridden by subclasses to print an item.

Implements SoVectorizeAction.

void SoVectorizePSAction::printViewport void   )  const [protected, virtual]
 

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Should be overridden by subclasses to set up the current page viewport.

Reimplemented from SoVectorizeAction.
