Changeset 9754 for branches/plugin-system/plugins/length_notifier.py

Timestamp:

Author:

Message:

Added plug-in deactivation mechanism, which allows plug-ins to clean up after themselves (eg. disconnecting handlers made in GUI); GUI extension points handlers are removed from list.

Updated Length Notifier plug-in so that it can be properly deactivated.
