- cleanupContext(context=None)
- Cleanup all held pointer objects for the given context
Warning: this is dangerous, as if you call it before a context
is destroyed you may release memory held by the context and cause
a protection fault when the GL goes to render the scene!
Normally you will want to get the context ID explicitly and then
register cleanupContext as a weakref callback to your GUI library
Context object with the (now invalid) context ID as parameter.
- delValue(constant, context=None)
- Delete the specified value for the given context
constant -- Normally a GL constant value, but can be any hashable value
context -- the context identifier for which we're storing the value
- getContext(context=None)
- Get the context (if passed, just return)
context -- the context ID, if None, the current context
- getValue(constant, context=None)
- Get a stored value for the given constant
constant -- unique ID for the type of data being retrieved
context -- the context ID, if None, the current context
- setValue(constant, value, context=None, weak=False)
- Set a stored value for the given context
constant -- Normally a GL constant value, but can be any hashable value
value -- the value to be stored. If weak is true must be
weak-reference-able. If None, then the value will be deleted from
the storage
context -- the context identifier for which we're storing the value
weak -- if true, value will be stored with a weakref
Note: you should always pass the same value for "weak" for a given
constant, otherwise you will create two storages for the constant.
