In the Qt backend we use event filters a fair but so we don't need to subclass qt widgets, but this has led to some issues around reference cycles and object lifetimes.
We should develop and implement patterns for testing that the even filters work as expected and also that they are cleaned up properly during garbage collection (eg. can handle situations such as Python objects not longer existing).
