How to handle unexpected exceptions? Is there any type of error event?

[Apocryphon-X]

Hi, I want to know if there is a way to handle unexpected errors using the event system (the closest discussion I found is #2819). I want to catch any non-critical error without having exit the app. This way the end user doesn't see the app crashing but instead it can see (i.e.) a nice notification/toast like this:

Note: I made the image above using on_worker_state_changed but I want to see if it's possible to handle errors that aren't from async workers this way.

There isn't, and I wouldn't generally recommend it. If an error is unhandled, your app could be a an unpredictable state.

If you really want it, you could wrap your handlers in a try / except block. Or you could implement a decorator which catches exceptions and posts the notification.

I see, thanks for the advice. Then I'm closing this as answered:)
