Even after that, it'll require quite a fair bit of help from Scribus's core code to support even notification of events in a safe way. Intercepting events to do something /instead/ or to ignore the event will probably be trickier too. The only exception is events that're clearly related to a single Qt signal, in which case the event hook can be a method that calls a series of Python hooks and if none of them handles the event just re-emits the signal to the "real" slot. Those are not only fairly easy and safe to handle, but the hook has zero runtime cost (since the signal can point straight at the real slot) until a Python script asks for a hook to be created. So, it's possible, and I was interested in doing it for a few things like file open, etc. It should even be possible to support event filters in python for at least some hooks. Right now, though, it's not implemented and it'll probably wait (as Craig B. said) until the Scripter gets an update/rewrite to make it more maintainable once the 1.3.x core code settles down. -- Craig Ringer
