Using match case for key pressing in different class

[JPLost]

I was poking around coding and noticed problem.

If the loop is

      while running:
          while sdl3.SDL_PollEvent(ctypes.byref(event)) != 0:
              result = event_handling.react(event)
              if event.type == sdl3.SDL_EVENT_QUIT or result == sdl3.SDL_EVENT_QUIT:
                  running = False
                  break

And I have event_handling.react as instance running from different file

import sdl3

class EventsHandler:
    def __init__(self):
        self.action = None

    def react(self, key):
        self.action = sdl3.SDL_DEREFERENCE(key).type
        match self.action:
            case sdl3.SDL_EVENT_KEY_DOWN:
                if self.action.key.scancode == sdl3.SDL_SCANCODE_Q:
                    return sdl3.SDL_APP_SUCCESS
                return self.action
            case sdl3.SDL_EVENT_KEY_UP:
                if self.action.key.scancode == sdl3.SDL_SCANCODE_Q:
                    return sdl3.SDL_APP_SUCCESS
                return self.action
            case _:
                return self.action

It will give AttributeError: 'int' object has no attribute 'key', but still work as expected.

You're trying to access the key variable from SDL_Event.type instead of SDL_Event.

def react(self, event: sdl3.SDL_Event) -> sdl3.SDL_AppResult:
    match event.type:
        case sdl3.SDL_EVENT_KEY_DOWN:
            if event.key.scancode in [sdl3.SDL_SCANCODE_Q]:
                return sdl3.SDL_APP_SUCCESS

    return sdl3.SDL_APP_CONTINUE
