OpenGL. platform. baseplatform

Base class for platform implementations

Functions

_find_module( exclude = ('OpenGL.platform.baseplatform',) )

Classes

class BasePlatform( object ):
Base class for per-platform implementations
Attributes of note:
EXPORTED_NAMES
set of names exported via the platform module's namespace...
GL, GLU, GLUT, GLE, OpenGL -- ctypes libraries
DEFAULT_FUNCTION_TYPE
used as the default function type for functions unless overridden on a per-DLL basis with a "FunctionType" member
GLUT_GUARD_CALLBACKS
if True, the GLUT wrappers will provide guarding wrappers to prevent GLUT errors with uninitialised GLUT.
EXTENSIONS_USE_BASE_FUNCTIONS
if True, uses regular dll attribute-based lookup to retrieve extension function pointers.
CurrentContextIsValid( self )
Return boolean of whether current context is valid
GetCurrentContext( self )
Retrieve opaque pointer for the current context
checkExtension( self , name )
Check whether the given extension is supported by current context
constructFunction( self , functionName , dll , resultType = <class 'ctypes.c_int'> , argTypes = () , doc = None , argNames = () , extension = None , deprecated = False , module = None )
Core operation to create a new base ctypes function
raises AttributeError if can't find the procedure...
copyBaseFunction( self , original )
Create a new base function based on an already-created function
This is normally used to provide type-specific convenience versions of a definition created by the automated generator.
createBaseFunction( self , functionName , dll , resultType = <class 'ctypes.c_int'> , argTypes = () , doc = None , argNames = () , extension = None , deprecated = False , module = None )
Create a base function for given name
Normally you can just use the dll.name hook to get the object, but we want to be able to create different bindings for the same function, so we do the work manually here to produce a base function from a DLL.
createExtensionFunction( self , functionName , dll , resultType = <class 'ctypes.c_int'> , argTypes = () , doc = None , argNames = () , extension = None , deprecated = False , module = None )
Create a base function for given name
Normally you can just use the dll.name hook to get the object, but we want to be able to create different bindings for the same function, so we do the work manually here to produce a base function from a DLL.
errorChecking( self , func , dll )
Add error checking to the function if appropriate
finalArgType( self , typ )
Retrieve a final type for arg-type
functionTypeFor( self , dll )
Given a DLL, determine appropriate function type...
getGLUTFontPointer( self , constant )
Retrieve a GLUT font pointer for this platform
install( self , namespace )
Install this platform instance into the platform module
nullFunction( self , functionName , dll , resultType = <class 'ctypes.c_int'> , argTypes = () , doc = None , argNames = () , extension = None , deprecated = False , module = None )
Construct a "null" function pointer
safeGetError( self )
Safety-checked version of glError() call (checks for valid context first)
wrapContextCheck( self , func , dll )
Wrap function with context-checking if appropriate
wrapLogging( self , func )
Wrap function with logging operations if appropriate
class _CheckContext( object ):
__call__( self , * args , ** named )
__getattr__( self , key )
__init__( self , func , ccisvalid )
__repr__( self )
__setattr__( self , key , value )
class _DeprecatedFunctionPointer( _NullFunctionPointer ):
__call__( self , * args , ** named )
class _NullFunctionPointer( object ):
Function-pointer-like object for undefined functions
__call__( self , * args , ** named )
__init__( self , name , dll , resultType , argTypes , argNames , extension = None , doc = None , deprecated = False )
__nonzero__( self )
Make this object appear to be NULL
load( self )
Attempt to load the function again, presumably with a context this time
