ClientHandler, DisplayHandler, LifespanHandler, etc. · Issue #215 · cztomczak/cefpython · GitHub

Module cefpython.handlers.

When user's code creates MyClientHandler it can use these interfaces to check if his callbacks signatures are declared properly - to look for typos or deprecated callbacks removed from upstream CEF. Also would be useful for auto completion.

These handlers interfaces should be auto generated from source code - create it as part of translator.py? (Issue #214)

Python has the concept of abc - Abstract Bases Classes - see:

Example:

class ClientHandler(metaclass=ABCMeta):
    __subclass__ = {DisplayHandler, LifespanHandler, ...}

class MyClientHandler:
    def __init__(self):
        assert issubclass(MyClientHandler, ClientHandler)

The example above probably requires implementing all callbacks - we only need to validate functions that have been declared. Whether such callback name is valid and whether its number of parameters are valid.

Also do this for other non-handler classes, but which also act as callbacks:
