class ExtensionManager(object) |
| |
Object managing OpenGL extension loading and initialisation
There are a large number of OpenGL extensions available,
and it is generally necessary to initialize the extension
for each OpenGL context. This class attempts to provide
a generic interface for instantiating and querying for the
extension's current status with regard to a particular
Context.
This object is normally accessed via ContextObject.extensions,
which is set up by the setupExtensionManager method of the
base Context class, which is called before the OnInit method.
Attributes:
modules -- mapping from "cleaned" module name to module
object (that is, the actual python module representing
the extension)

Methods defined here:
- __init__(self)
- Initialise the extension manager
This implementation simply creates the modules attribute.
- hasExtension(self, moduleName)
- Query whether an extension is currently loaded
moduleName -- the "cleaned" module name being queried
- initExtension(self, moduleName)
- Initialise an extension module for the context
This must be called within a "setcurrent" environment
to ensure that the owning context is the one that's
initialised...
moduleName -- the module name being queried, will be
"cleaned" before processing...
If the extension has already been loaded, this just
returns a pointer to the already existing module.
- listGL(self)
- Return list of OpenGL extension names
- listGLU(self)
- Return list of GLU extension names
XXX This is currently broken with PyOpenGL 2.0.1
- listWGL(self)
- Return list of WGL extension names
