Detailed Description

The SoShapeKit class provides templates to insert what is usually needed for shape nodes.

Member Function Documentation

SoType SoShapeKit::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoSeparatorKit.

SoType SoShapeKit::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example: 

  void foo(SoNode * node)
  {
    if (node->getTypeId() == SoFile::getClassTypeId()) {
      SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
    }
  }

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: 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 for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoSeparatorKit.

const SoFieldData ** SoShapeKit::getFieldDataPtr (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.

Reimplemented from SoSeparatorKit.

const SoFieldData * SoShapeKit::getFieldData (void) const [protected], [virtual]

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoSeparatorKit.

const SoNodekitCatalog * SoShapeKit::getClassNodekitCatalog (void) [static]

Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoSeparatorKit.

const SoNodekitCatalog * SoShapeKit::getNodekitCatalog (void) const [virtual]

Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoSeparatorKit.

const SoNodekitCatalog ** SoShapeKit::getClassNodekitCatalogPtr (void) [static], [protected]

Returns the pointer to the pointer of the nodekit catalog for this class.

Reimplemented from SoSeparatorKit.

void SoShapeKit::initClass (void) [static]

Does initialization common for all objects of the SoSeparatorKit class. This includes setting up the type system, among other things.

Reimplemented from SoSeparatorKit.

void SoShapeKit::setDefaultOnNonWritingFields (void) [protected], [virtual]

(Be aware that this method is unlikely to be of interest to the application programmer who does not want to extend the library with new custom nodekits or draggers. If you indeed are writing extensions, see the information in the SoBaseKit class documentation.)

This is a virtual method, and the code in it should call SoField::setDefault() with argument TRUE on part fields that should not be written upon scenegraph export operations.

This is typically done when:

1.
field value is NULL and part is NULL by default

2.
it is a leaf SoGroup or SoSeparator node with no children

3.
it is a leaf listpart with no children and an SoGroup or SoSeparator container

4.
it is a non-leaf part and it's of SoGroup type and all fields are at their default values

Subclasses should usually override this to do additional settings for new member fields. From the subclass, do remember to call 'upwards' to your superclass' setDefaultOnNonWritingFields() method.

Reimplemented from SoSeparatorKit.
