How to do AddonPreferences using extensions_framework? I have seen scripts taking user preference values using classes built over AddonPreferences. Is it possible to do the same using extensions_framework by Doug Hammond. Why I am asking this is I need to get a path to an executable from the user, like a path to a renderer. The script which I made does all its class registration / unregister happens through EF. So is it possible to get the path from pref?
No (as of 2.68), the Python extensions_framework directory has no references to AddonPreferences.

You could contact Doug Hammond about this or check on adding support yourself.
