CallbackGraphicsWindow

from panda3d.core import CallbackGraphicsWindow
class CallbackGraphicsWindow

Bases: GraphicsWindow

This special window object doesn’t represent a window in its own right, but instead hooks into some third-party API for creating and rendering to windows via callbacks. This can be used to allow Panda to render into an already-created OpenGL context, for instance.
