EventHandler
from panda3d.core import EventHandler
- class EventHandler
Bases:
TypedObjectA class to monitor events from the C++ side of things. It maintains a set of “hooks”, function pointers assigned to event names, and calls the appropriate hooks when the matching event is detected.
This class is not necessary when the hooks are detected and processed entirely by the scripting language, e.g. via Scheme hooks or the messenger in Python.
