OpenGL.GLU.glustruct

Base class for GLU callback-caching structures

Classes

class GLUStruct( object ):

Mix-in class for GLU Structures that want to retain references to callbacks

Also provides original-object-return for the "datapointer" style paremters

Each sub-class must override: CALLBACK_TYPES -- maps a "which" constant to a function type CALLBACK_FUNCTION_REGISTRARS -- maps a "which" constant to the registration function for functions of that type WRAPPER_METHODS -- maps a "which" consant to a method of the structure that produces a callable around the function which takes care of input/output arguments, data conversions, error handling and the like. Creates a dictionary member dataPointers if original-object-return is used Creates a dictionary member callbacks if callback registration is used

_as_parameter_

Gets as a ctypes pointer to the underlying structure

addCallback( self , which , function )

getAsParam( self )

Gets as a ctypes pointer to the underlying structure

noteObject( self , object )

Note object for later retrieval as a Python object pointer

This is the registration point for "original object return", returns a void pointer to the Python object, though this is, effectively, an opaque value.

originalObject( self , voidPointer )

Given a void-pointer, try to find our original Python object

ptrAsArray( self , ptr , length , type )

Copy length values from ptr into new array of given type
